7.5 isnt really a low turn motor

Instructions for SP ESC's say hybrid boost from 4.5-10.5 turn motors.

I mainly just need more speed on the straights. Power is fine everywhere else. Going to play around with the Hybrid boost and see what I can come up with.

Are you using a SP 7.5 motor? I run a SP 7.5 v3 with 20 degrees of timing and run the Mod2 firmware with 11.5 degrees of esc timing. Geared at 81/20. My B44.2 is as fast as the guys with 5.0 motors.
My opinion is that you don't need boost for offroad. If you feel you do, get a lower turn motor.

After racing with my Reventon R in my T4.1 for a few weeks now, have to say I am very impressed with it. Very smooth and hastle free. Was using an LRP SXX V2 before, and this ESC is just about as smooth. Feeling of the brakes is awesome, makes for a very easy to drive truck and does not come on too hard.

The SP software is simple to use, and Speed Passion has a great tutorial on how to download the software and get your vehicle plugged into the programmer and computer.

My only complaints:
-BEC issue (Some come with the good BEC, other's don't, but SP will send you the replacement free of charge)
-Long reciever wire. Thankfully you can put a smaller one on, but out of the box, the stocker is easilly 200+mm long.
-A little tall, even with the fan off, might not fit easilly on the side of a 2wd buggy chassis and clear the body.

Is anyone using any other capacitors? Have another Reventon I want to use but need to find a cap local before Wed. Thanks!

I'm thinking of buying a 6.5 and see how it feels. Local track just got bigger, so I think a new motor might be the best option.

On the reciver wire, Depends on which ESC. I have the s in my SC10, little long, but long enough can plug in box set program box flat on table, (curl extra reciever wire around a screw driver pull it out) sensor wire long enough, My gt2.0 in ym B44.1 was like the shortest one they offer just barely long enough, But the sensor wire to short. not long enough to adjust ESC in a way wires werent pushing body up.

My s did come pre wires, All leads soldered to esc, and a deans plug on it. Score, Saves me a plug and some solder time.

Reventon Pro came with two wires. Short one for the receiver and then a longer one to reach the programmer. Once I saw all he extra stuff in the box I fell in love. Second night out and I take my class for the night. Was night and day difference compared to the on/off switch I had been using (MMP). Great unit!

Had my worst fear confirmed. While updating firmware via wireless, there was a load error and ESC would not stay on for more than a few seconds. Tried a few PC's to get the software restore working but we had issues with the windows USB drivers.

Left it for a local SP doctor to take a look at it. The more I understand how this tech works, the more it frightens me.

I was really excited to setup the wireless module in my car so I could make adjustments from the driver's stand in practice. I pulled into the pit lane and adjusted my ABS and drag brake a slight bit. Apparently, any adjustment requires the ESC to be power cycled. So really, the only thing that wireless provides me at runtime is real-time statistics. ESC temperature, battery voltage.

I understand having to power cycle but I wish there was a way to remotely do that. Maybe power down, wait a few seconds and power up?

for racing you need to be in blinky. running the other firmware with timing turned down is still cheating. (officially anyway).
DRRS - well, i think of it as punch. If you want more rip off the line, turn it up. For 17.5 I would expect all but the true novices would want it cranked to 11. haha jk it only goes to 9.

Got in some motors, trying to decide which to use. the ones I got in are:

13.5 1 cell Speed Passion motor
13.5R MMM SP Motor
17.5R MMM SP Motor

Now, mind you the track I will be using these at runs full mod. But its very tiny. Torque is king so guys run some really hot stuff to punch it over the jumps. Last year I did run a 17.5 as the layout was conducive to doing this and it worked well till it changed to more 180s.

I would like to run say a less hot motor (8.5 V3.0 Comp right now) and play with settings for power. I also have a 12.5 rotor I can drop in too which originally was going to my touring car for 17.5 class

So here is what I am thinking of trying, going with the MMM motor, possibly the 17.5R but put in the 12.5 rotor and maybe the black timing board instead of the Red one?

track is at best I think 50 x 50 or even smaller. carpet offroad with jumps, so I can put the power down. this would be in a 2wd buggy. I am using a GT2.1 Pro Stock ESC, 428 mod software but may change that to the stock one.

As a few have stated, you must run Stock0 to be "legal" in the blinky 17.5 class

One of Speed Passion's local guys here who runs for Xray just built up his XB4 with a MMM 6.5 and Reventon Pro. He plans to do more testing this weekend so I can see if we can get some of his setup info. His car is pictured here...

See my teamspeedpassion.com link above. It shows a good number of pictures of people running Reventons in 2WD buggies. The size really isn't an issue from what I have seen at various tracks.


What this guy said :) Only difference I would say is people seem to be anywhere from 5-6 to 9 DRSS based on how smoooth they drive. I just cut it in the middle and run 8 LOL

???? A little help please
 

What's the difference in buy rev pro & 10.5 motor on USA warehouse vs the box combo on intl site big price Disparity. Is the intl stuff better? Also want to run a 17.5 combo in an sc10 2wd is the rev r or s enough or do I need the pro?? Thanks for help

What firmware are you guys finding the best....I have a Reventon pro and R.. Off road sc and buggy

i really like the mod 2.
