IWANT ONE!!! LOL

Thanks Eric, this was the info I was looking for.
When you say Max timing on the end bell you mean 45* correct? I was looking at another guys setup on the weekend and he had the end bell timing cranked to 60*(?) his car was very fast and temped at 155* with a fan.

Just bought myself a new Schumi Cat SX3 4WD Buggy and need a good ESC/motor combo to match up to it. I was going to go with a VTX10R/8.5 combo but after reading through many pages here it seems moslty 2WD guys are using this system. I do not want to have any heat issues. Tekins are King where I live and through the winter months we run on indoor carpet with jumps so I may pick up a 5.5 turn motor if needed later on. Anything I should know before I purchase the system?

You will have no problems pushing your 4wd buggy around with the VTX10R and 8.5 or 5.5. I use the VTX10R in my 6lb 14oz 4wd SC truck with a 550 motor without the fan kit. It's really that good! :nod:

Well guys my 10r is Money I messed with some drag brake and i love it last night i tq'ed and won our mod buggy main. Had a few people drive my car after we were done everyone loved the speedo they just couldn't handle all the motor i had. lol

I also did my personal best lap time with a horrible driving car 14.2!! With the Track record held at a 13.7 by a B44.1 Driven by a AE sponsored driver so i felt accomplished.

Thank You Viper :nod:

You will love the 17.5. I currently run one in my 22 and it's a rocket. I plan to add 13.5 and 10.5 to my arsenal. I have lap record with the 17.5 on our small indoor carpet Offroad track so I'm in no hurry. :)

I use the VTX10R with a 7.5 in my 4wd (TQ SX10 4w), no holes cut to cool the motor or speed control, no fan - no heat issues. No every track is a little different but the three I have run it at have been great - too powerful at times.

I am planning on the vtx10r with my losi ten scte with a 4.5 motor. I am hoping there is heat issues. I will be the first to run viper esc at this track as tekins are very popular here.

Tq'd and won mod buggy at Trcr, lot's of good competition.
:nod:

Look back through the thread (sorry list the exact page), Losi Project Manager Ryan Dunford posted his esc set up, he does not use a fan and has no issues using the VTX10r and XL motors.

Larger Rotor
 

I changed to the larger rotor (13.8) in mod buggy 7.5 motor this past weekend. WOW it really helped with temp's and slowing the car down without using a lot of drag brake! I'm using Paul Sinclair set-up for the speedo, except for some personal preferences. Raced at the RC Factory in Ohio this past weekend. I qualified 3rd in the A with a lot of very good competition. Jason Engle (Butters) tq'd with Chris Doseck 2nd. The competition was incredible for this race. Racers that attended were: Curt Schlister, Eric Clark, Paul Sinclair, Dustin Richards, Luke Richards, Curt May, Dax Madden, Dan Griffin, Brandon Marsh, JP Richards just to name a few. If you need a little more braking, without changing speedo settings, try the larger rotor. Viper products and service are awesome.

Out of curiosity what size rotor comes stock in the 17.5? 12.3, 12.5?

12.5 if I'm not mistaken.

I was hoping that was the answer :)

What radio system/receiver are you using?
