as a rookie AND on budget...I'm glad I stumbled onto this thread. Lots of good information. 2wdMod, or any other guru's, I would like your suggestions. I've got an HPI Blitz ese roller and need advice for a brushless set-up that will be plenty powerful/fast enough to have fun with...but will also be at least competitive in a SC2wd Novice class (we can run what we bring). I'm leaning towards the HobbyKing esc 60a and a Tacon motor...just not sure which motor and if the 60a is high enough (may want to throw a lower turn motor in it occasionally for fun and a 3s lipo).

Bottom line, what woud be a good balanced set up for me to get going with, which will still be pretty inexpensive?

thanks

the 60a will handle down to a 5.5(5000Kv) motor...personally I would go with the 2950 kv..very versatile..through gearing and esc timing you can tame it down to run novice , but then if you want to haul the mail bump up a tooth or 2 and add some timing and she comes to life!!

I really liked the Tacon 3650 3500kv I had in my 2wd slash. I didnt feel like it was too much, but you did need a bit of throttle control. I like it cause it was punchy. If I got off line or in trafic and lost momentum I still had plenty of bottom to blurp the throttle and clear most anything on a short or no run up. the bottom line...it was fun to drive.
Compaired to my Novak balistic 13.5 3200kv....I could run faster and smoother lines, but it had no punch like the tacon...I had to run a good line and go WOT to clear most of the jumps, if i was off or lost momentum there wasn't enough extra there to get me out of trouble. of course it was better for racing to hook up and go, it got traction through lack of power

I would rather feather around the track and learn throttle control and have the extra power there when I want it. Its just more "fun" to drive

I never ran the tacon on 3s so I dont know how it would do. never felt the need it had plenty of power for me. I would run a smaller pinion on 3s

another note, if you want to know what the power of the tacon 3500kv, It was dead even with the Traxxas VXL 3500 that my buddy had in his truck. So if you have seen a Slash with a VXL and like the power, thats what you will get

if I remeber I think my Tacon ran cooler than the VXL

2wdMod and Dirtman...thanks for your thoughts. Really appreciate the insight.

Ok so the next Budget speedo on the testing block is the Hobbywing Justock 45a sensored system.I need to put my DEX 210 on a diet and by switching to this economy BLINKY ONLY speedo I trim 40gms from the wieght of the 60A with fan..Being only 45a I expect to use it in my 2wd buggy with motors down to either a cranked timing 13.5, or a mild timing 10.5, but for the most part it will see 17.5/blinky dutyprice is $63 and its in the US.

thats funny, I was just looking at the 45a HW this weekend. Know we will see. Cant wait

I thought I'd update with some experiences I had with a new Bullistorm 60A ESC, the one with the purple housing & heatsink. I purchased it for $42.51 with free shipping on eBay.

Overall, I'm happy with it but as it appears to be one of many Chinese knock-offs, quality was hit & miss. Some of my frustrations were my own doing--not having my FlySky GT3B transmitter set to "REV" for the throttle channel caused some unusual behavior for the Bullistorm, and I had some issues with my 8.4V NiMH battery pack--but not with 7.4V LiPo packs.

After connecting everything, I noticed the fan would only spin for a second or two, then stop. The ESC performed as expected otherwise, I was able to program it with the button, but it bothered me that the fan didn't spin. After a short time, I was noticing that dreaded "burning wire" smell. I disconnected my NiMH and re-checked everything. Nothing was amiss, so I reconnected the battery and tried to re-program the ESC. I saw a tiny wisp of white smoke emanate from the ESC.

After all was said and done, I'd removed the fan and saw that the fan was a cheap POS unit and the blades weren't even allowed to spin freely. Without too much pressure, I could easily distort the outer housing of the fan, and this seemed to be part of the problem. I think the fan being unable to spin caused the soldering inside the ESC for the fan leads to fry. I replaced the fan with a same-sized Novak unit that's plugged into CH3, and it runs fine, nice and smooth and almost silent. The ESC otherwise seems unharmed.

Now on to the other issue I experienced. After resetting the ESC's neutral/forward/reverse, I noticed that it would only spin the motor with testing for a few seconds, then die. (I'd removed the pinion gear so the motor could just spin freely.) It did this several times. Each time, I'd turn off/on the ESC and it worked for a few seconds, then would die again. I still had steering function but absolutely nothing from the ESC. When it did this, a red LED inside the housing would blink on and off.

I went through the Chinglish in the manual, reading as best I could, and it appeared this error light was indicating a low voltage cut-off was happening. It didn't make sense to me because the NiMH was 8.4V and quite recently charged. Maybe it lost it's charge in 2 weeks, or there's an issue with the unit's voltage detection for a NiMH battery pack, but whatever the case may be, the ESC functioned flawlessly with a 7.4V LiPo connected. It never died.

I'll have to recharge the NiMH pack and try again later to see what happens. Has anybody else experienced this with NiMH packs & these HobbyWing clone ESC's?

Anyway, in conclusion, the ESC seems to be working fine with a Tacon 3650 11.5T motor & FlySky GT3B with both channels set to reverse and a Novak fan powered by CH3 from the receiver.

I just put that combo in my SCTE. The motor runs a little warm, but that may be due to my truck binding a little. I'm going through it now to be sure. It makes good power and is pretty smooth for a sensorless setup.

I'm considering one of the Xerun combos for a 1/8 buggy, but I am having a hard time deciding between the M5A, M6B, or M7A combos. Which would be the best balance between power and run time on 5000mah 4s? I would like to get around 20 min of run time if possible while still having competitive speed. This is going in an Ofna LX2e.

I have a couple of the Xeruns wired with tekins 1400 and 1900 kv motors. Overall testing with 4s 5s 6s battery packs

I get around 25 minutes with 4s 5000mAH on the 1900kv (motor runs bit warm due to taller gearing but battery stays cool since its a gens ace 40C pack)
Around 10 minutes with 5s 2200mAH on the 1900kv (system runs hot have crappy gens ace 25C packs here motors quite cool to touch)
Around 20+ minutes with 6s 2650 mAH with the 1400kv (system runs super cool battery pack has no noticeable change in temp and motor's a tad bit warm)

Overall I like the tuning/punch/ cool running of the 6s with 1400 kv combo best. If you are already invested in batteries or if track forces 4s (which is stupid just for ROAR sake) then you got no choice. But I would go with the 6s option. Great power cool and efficient.

If I were you I would go with the xerun m7a with I believe the 1800kv motor. Its flexible enough to run with 5s/6s packs and of course 4s geared tall. Also if you use a sensored motor, you do drop some KV from rated value as compared to a sensorless motor.

You won't get 20minutes on none of those will. You need something with lower kv and higher voltage for efficency to make that runtime. Like me I run 1550kv/5s or 6s. With the higher voltage my truggy runs just as fast as a 4s 2000kv setup.
You have the best chance running a M7a 1800kv on like a 5300mah 5s or 50006s pack. Hobbyking has some good priced 5800mah 5 and 6s packs. Also they have a 8000mah 4s pack that will reach your goal almost all those choices.

Anyone tried the xerun sct pro esc? Was considering trying one in my scte and possibly my 1/8e buggy. Lookin for a sensored esc

Thanks! I am limited to 4s batteries at our local track.

hopefully you fixed the binding, if so how is it running now? gearing and temps?
one of the lhs is thinking of carrying them but is having one of their employees test it out and compare it with some of the high end brushless set ups, depending on your review and if they'll be carrying them maybe one will be in BNIB SCTE.


thanks!
