Thanks. I'm a longtime Viper guy... Yes, this is for my son's Tekin. I was considering the viper caps as they would allow for a real nice/tidy install. I think before I do, I'll just add another cap to his existing esc and see if he can tell any difference. Thanks for the info.

Thanks Wildcat.

I'm more anal. I re-calibrate every time I change motors. Do I need to? probably not but it's just something I started doing a while back.

I recalibrate every time I pig-handedly choose the wrong model on my transmitter and wonder why nothing then works.

lol...I made a video on how to change profiles, calibrate and how to fail at it, lol. I will link after upload is done. I show what NOT to do. And sure sure, I did it wrong on purpose...yeah thats right....

Hahaha, the expression on your face when we were talking about it afterwards was priceless. I was just happy that I wasn't the only person who did dumb stuff like that

with A64 - profile 2, set the brakes how you like them, adjust punch to control wheel spin (less is better). Vent holes always help in 4wd, I have even backed off physically timing in motor before to give little better control.

To answer the cap question from the other page --
Yes adding more caps does help the system - will make everything a bit more efficient and provide little extra power when getting on the throttle. There is a limit with battery size. Example on 2s, really don't need more than our Pro6 pack -- but we have done it before.

Calibration -
Anytime esc is used with new or different receiver, its a good idea. Shouldn't make a difference with motors - think Bob has little OCD -

ya think? maybe it's just time to up my meds :P

ok viper is sending me a replacement esc. man these guys are quick. only have to hit 1 button before a real person is on the line. everyone i talked to was great. very cordial and understanding.

Thanks nikos, And thank you everybody else for the 2 cents. Hopefuly I can get out this week end and put some laps down with the B5 and see how it does.

+1, great people

Viper VTX10 gearing for DEX210

In case anyone googles this, I ran my DEX210v1 last weekend with the VTX10 ESC and 8.5 turn combo. 78 tooth spur and 23 tooth pinion. 15 degrees Celsius outside, the motor came off the track at under 100 degree f without timing and the ESC at 86f.

Tempted to screw around with timing since I have ample heat to play with, but I can't use all the speed as is, and as it is a loose track, I certainly don't want any more torque. Runs nice and cool, even without a built in fan. Might just leave it as is.

lol sounds like what I was getting close to gearing on my end of things using a 10.5 in my dex 210. I have to see what gearing I am at but I was basically cool to the touch, no timing.

Deven - if you can't put the power down, don't try to add timing. Sure the theory is the motor will run faster (it will), but if you don't have any control, it will not help you. Focus on the chassis, get more grip -- use the power you can't right now before you try to add more.
