What motor are you useing in your SC104x4? is it one of the 1/8th scale motors? and are you running 2 cell with it? the reson i ask is i am using the blaze 550 and like it but SP is not going to put any more out any time soon so i am looking for a replacement motor.

Is this blinky class? reason I ask is that you may find you want to get some of the sensor boards then. The green one felt pretty good as a starting point but I can see guys going with yellow especially if the other guys are running full timing on there motors.

what exactly is going on with SP on the offroad front, in particular 1/10 SCT and 1/8 E buggy? I wanted to try one of there 1/8 offroad motors but for some strange reason they released their motors that are sensored in a very odd Kv range, and the ones that would have been perfect as sensorless. For racing nowadays, people pretty much want Sensored motors in the Kv range that there current sensorless lineup is in?

As for the blaze, I hope that maybe they are going to look into a 540 4 pole design at a minimum.

I have the Reventon Pro 17.5R kit. comes with 120amp esc and motor. I flashed the esc to allow reverse, yet reverse is very weak and sometimes doesn't work. any idea why this happens? running a version 3. with a 2s lipo on a b4.1 worlds edition.

my initial thought was the controller. its a skyfly gt3b. the controller works great for reverse in all my other cars/boats. (orion r10 pro, toro micro esc)

when you flashed the ESC software, did you reset your radio end points and rebind the radio to the ESC?

What amount of power to you have set for reverse as well?

I have switched from tekin rs pro to rev r in my b4 & a rev pro in my b44. I am extremely happy with the switch:nod:. I also switched from tekin rx8 to the SA II, but I'm not as happy with that switch:(. Has anyone heard any rumors of a new 4s ESC coming, maybe a reventon 8?:tire:

Thanks for the reply, I sent off another email today and got a reply within 1 hour. My first message must have not gone through.

Thanks!

yes, i have reset the radio endpoints to 100% and i recalibrated the radio to the esc. i have 50% for reverse. my throttle adjustment is at Neutral as well.

LSR is a great place to race hope to see you out there.

I take it 100% reverse isn't powerful enough either ... I know that from what I have seen of there reverse the few times I used it on the GT line, at times it would detect "brake" even though it should have found reverse on the second back push of the trigger, if my understanding of how it works make sense.

Curious if it could be that at some level we can't easily see, it is detecting "Forward" after we do "Brake", hence, instead of going in "Reverse", it thinks we should do "Brake" again?

Helping a buddy pick out a new system for his e-buggy. I am digging my Reventon Pro and am trying to find some Speed Passion stuff for him since he's being budgeted by the old lady. Is the Silver Arrow v2 the newest and greatest? Anyone have any idea where I can find one in stock? Also what motor would we be looking at. Some are listed in "turns" and some "Kv". Which is the newer version etc.. Thanks gents !

from speed passion, yes its there current unit.

You usually need to look on speed passion's stores to see in stock status. That is where to get it the cheapest usually. It runs about $75 or so shipped in the USA last time I saw it listed.

As for motor Kv, to be honest if this is for racing, you will want to get a sensored motor, and on 4S, the current SP line Kv range in my honest opinion is too high. I would want to stay around 1800Kv - 2200Kv max. I believe there lowest in sensored configuration is like 2400Kv or so. A real shame. You may find he likes the higher Kv however.

As for mating up the SAV2 with another brand motor, it works really well with Tekin's motors like the 1900Kv or 2050 Kv ones.

That's what I figured. Thank you good sir!

no prob. I feel its a great speed control. A bit big, but it feels robust.

SP_CS: What happened to the Cirtrix or whatever it was called R8 Speedo?

That's a good point. I will look into it and see if I can figure anything out by reprogramming it, and testing ALL settings on my controller. I will get back to you with my findings. I appreciate the help!

no prob! I rarely use reverse so take that with a grain of salt. I just noticed it when mainly playing with the vehicle my daughter was using which for her reverse is a must as the old man isn't able to do wind sprints to get her vehicle nowadays!

Something else to look at is your dead band. If it is to narrow the ESC might not see true neutral every time. I ran into this with my SAV2.

Coming from an RX8 to the SAV2 I find it EXTREMELY smooth & easy to drive. It has enough things to change in the setup to keep most any tinkerer busy for a while. It makes a great budget ESC or up grade from a RTR esc.

That said, an experienced racer will find some faults. The SAV2 is not as efficient as the RX8. This causes the motor to run a little hotter (only 15* difference, but it is hotter consistantly). I don't get quite as much acceleration or top speed either. All of these will only affect the top end racer who is looking for that tenth on his lap time. For mere mortals on a budget, the SAV2 is SO worth the money.

Personally I hope SP comes out with a Reventon 8 or another high end 4s-6s to compete directly with the RX8.

lol right now I need to turn down the punch on my SAV2 as with the Tekin 2050Kv motor its very beastly lol.

I wonder what htey have in store too. I am curious as to what happened to the Cirtix R8 as it was supposed to be pretty good. Maybe it will return in some other form?

Heck, on the SAV2, I personally would like them to just use a plug setup for the various wires versus having them come out of the sides of the case. This would make it "fit" in more areas as because now, you need to factory in the wiring poking out of the case! lol

Hideeho
I'm beginning to wonder if my SAV2 had issues right out of the box!

For reference when I was running an RX8 I used no boost/timing/advance or any other power adding settings. I had the current limiter @ 80. The EPA on my transmitter would vari from 75-90 depending on the traction (almost always at 85). I was as fast as any other buggy down the straight & topped out in about 50' (about 75' of straight). Acceleration was a touch slower than the really edgy buggies of the fast guys. After a 10 minute main I would temp the motor at 110*-120* & the ESC at 110*.

To start out I set the SAV2 to no timing, 8 on the drrs. It was a little smoother, but no where near as quick out of the hole. On long straights I was a little slower & still accelerating when I would get on the brakes. On short shoots between corners it was dramatically lacking in speed. After a 10 minute main I temped at 130*-145* motor & 120* ESC.

I played around with the settings & ended up with 16* (+/- I can't remember what the exact oddball number was) timing & 5 on the drrs. I was still lacking on the bottom end, but the thing was so smooth I would make up the speed in about 30' & hit a higher top end at the same 50' on the long straight. The draw back (the reason I didn't add more timing) was heat. After 10 minutes the motor temped at 150*-175* & the ESC @ 160*-170*. I didn't want to push the temps any farther than that.

I managed to fry (completely my fault doing stupid stuff with the BEC) my SAV2 & have the $ right now, so I'm going to try the forth coming RX8 gen2. There are 3 other guys at the track running them who won't trade them for anything. One guy had gotten his SAV2 while waiting on his RX8 to get repaired. When his RX8 came back he kept the SAV2. He liked his SAV2 so much that when another buggy impaled his ESC & he had to switch to his RX8 (that had come back from service) to finish his race day, he ordered another SAV2. The good thing about getting the RX8 is if I don't like it any more than the gen1 I can sell it quick & buy 2 SAV2's with $ left over:lol:

lol, that is so true on cost. SP should really keep it around and promote it. Being able to actually run 1/8 that cheaply esc wise is awesome.

Been looking at the rev pro and now with current sale I am going to get one. Looking at running in spare B4 I have. Just wondering how the motors stack up. Are they revvy or torquey? Is an 8.5 V3 comparable to an 8.5 reedy sonic? Is the out of the box firmware the way to go or should I be loading something different? Starting place for gearing? Thanks.

I run a Rev Pro in my B4.2 with SP V3 8.5.
I use the MOD 2 profile, geared 78/23 (8.82FDR).
Haven't run the Reedy, so can't give you a comparison.

Hideeho
In my b4 I run the rev r with the sp v3 8.5. I gear 26/78. It is BLISTERING fast, but smooth as butter so I can use that speed when there is any kind of traction. I can't compare it to a reedy, but I can tell you it has more torque than an lrp x12 8.5, is much smoother, & runs SUBSTANTIALLY cooler at the same gearing. One problem I have had is the sensor wire falls out rather easily. It doesn't do it every run, but it does happen often enough to mention it. It is actually still smooth sensorless so I haven't bothered to fix it yet, but one of these days I'll put a clip on it or zip tie it to fix it & everything will be peachy with this combo.

One other thing I have heard people mention is that the brakes are kind of weak. I have experienced that exact opposite. The brakes are smooth & powerfull. I set the brakes at full on the ESC & control the braking force from the transmitter by adjusting the EPA. I set my EPA anywhere from 30%-45% & I adjust it everyrun during practice laps before the race starts. I set it such that when I'm at full speed & slam it to full brakes the buggy decelerates & then locks slightly at the end as the weight gets fully transfered.

I have an X12 7.5 in my B44 and I feel it has the most torque of any other 7.5 i have tried so I am surprised to hear that about the SP.

thinking about getting one for a wheeler. I want to run a reedy sonic mach 2 6.5 or a reedy sonic mach 1 6.5. or maybe a boosted 7.5 I haven't decided yet. I heard somewhere that the speed passion doesn't like the reedy sonic motors too much?

Hideeho
As far as I know the problems are with viper, lrp, & tekin gens. 2cansam races @ my track & I'm almost positive he just put a reedy in his b44 with a rev pro. Send him an IM & ask him about it.

What does everyone think of the older competition v3 motors? For $32 on the US store website I was thinking of picking up a couple. Just don't know if they are outclassed by current motors on the market.

In mod, they are very viable.

If you are going to run blinky 17.5, you may want a few things with the motor that basically get it similar in price to other ones configured out of the box.

The big thing being the sensor unit for adjusting timing.

I hope that if they release a new motor in the future, they :

- Make a sensor unit that will give you the full timing range on 1 board
- Provide high torque rotor or high RPM rotor options out of the box

AND / OR

- Do like novak and allow you to configure a custom motor

When I asked about offroad motors, I was suggested to still look at the v3.0 versus the MMM by Solara I believe. I have the MMM 17.5 configured with the high torque 12.5 super 7 rotor and a variety of timing boards (Green right now) and I like it.

I too went from a rx8 to a SA v2 and never went back to the tekin. Ever since then I've owned over ten of the sp escs and all have ran great with zero issues.

We are going to start building an 8th scale outdoor track in the near future. I have an early Rc8e and updated worlds suspension. I was looking at budget minded Escs and the SA really looks promising.

Will it work on >4s? If I wanted to use 3s is it feasible? (Our indoor track allows 8th scale buggies toward the end of the tracks life cycle once It's blown out and about to be changed, and imo 4s still might be a lot)

My rev r started acting funny at practice today. I would run for about 5 minutes or so & the speed would dump down to the super low speed like it has hit lipo cut off. The 1st time it did it I assumed the battery wasn't as fully charged as I thought, so I put it back on charge & changed some setup stuff without checking it out. The lipo charged extremely quickly (>5 minutes) so I went back out. It did the same thing. This time I checked the LEDs. They were alternately flashing red then orange:confused:. One it cutoff the other is temp, but couldn't find what both together are. I temped the motor (sp v3 8.5) @ 118* on the end bell (hottest spot). The ESC temped @ 136* per the program card & 7.3v with cut off at 3.2v. I'm running 4* timing on the end bell, 18* in the ESC, & drrs 3, w/ mod 1 mode (iirc, the one with reverse). The temp on the ESC is a touch higher than usual (8*-10*), but the track was very loose today so I was spinning the wheels more than usual.

I didn't have time to go through & trouble shoot everything, so I'm trying to figure out the error code. Alternately flashing red then orange is not listed in the version of the manual I have. It does list flashing red as temp cutoff (temped way to low to trigger that) & flashing orange as low voltage cutoff (program card listed well above where its set). Any ideas what happened &/or how to fix it?

Its rated for no greater than 4S. 3S I am curious as well if it could work.

I know this is a late reply, however I just wanted to drop a note that this past weekend I got my DEX408 ready to race, which included the Blaze 2450kv. It fits fine. It's tighter than the T8 was in my buggy.

I recently got the DEX210 RTR could someone explain to me how to program the ESC to have reverse as I am just learning how to run on a track and reverse is a must when you hit the tubing and are in a wheelchair and can't get it yourself.

Hideeho
What does alternately flashing red-orange-red-orange leds indicate?

Sensor connection problem. Maybe the sensor wire have a bad contact. What motor are you using?

Hideeho
THANK YOU! I'm running an SP v3 8.5t. That might explain explain why my problems happened all at once. I was having problems with the sensor wire falling out of the motor, so I zip tied the wire to the motor. I probably got it too tight & pinched a wire (but it hasn't fallen out again :( ). The wire is rather old & used, guess I'll pick up a brand new one from the lhs tomorrow.

I also noticed tonight my fan has quit working. How much does the fan actually cool the ESC? Previously, with the fan working & the ESC not cutting off, I could run a full pack to cutoff & the ESC would temp 120*-130*. Tonight each time it cut off the ESC temp was 158* (exactly 70*c). Between no fan & sensor wire issues, would that account for 30*-40* difference (same gearing). The ESC temps are all per the program card. The motor has continuously temped @ 120* (temp gun on the hottest part of the can).

Happy so far, I purchased a Rev Pro and 8.5 first thing Monday morning. It was in my mail box Thurs. Installed electronics last night. Pretty straight forward. Got the buggy fired up, set slipper and went to bed. Can't wait to run it!

Hideeho
That was part of the problem. A new sensor wire made it SO much better. I'm still having issues with it hitting temp cutoff after about 7 minutes, but at least it is reading as temp cutoff now:lol:. I was running 25/78 w/ 5* on the can & 18* in the ESC that was hitting the cutoff after about 6 minutes. The program card showed 158* (70*c) & 120* on the motor. I went down to 23/78 & made it about 9 minutes, still not good for a 10 minute main:(. I took all the timing out of the ESC & ran to cutoff with the card showing 130* (100* on the can). I was going to start playing with ramping the timing & gearing back up, but I snapped my dif bolt:confused:, so I'll fix that & start playing with it during practice & qualifying tomorrow.
