I did notice that I can't pop wheelys anymore I think going to a pair of 3s or reducing the size of the pinion gear would give it the torque to flip itself over from a dead stop. Right now I'm running 20 tooth pionion and stock 68 tooth spur. I'll test a pair of 3s (also saved from the fire) tomorrow."
From everything I've read, the Twin Velineon setup is impressive. But as with most things, there are pros and cons.
You listed just about every pro known to man. LOL
I don't mean to be negative, but there are a few disadvantages to it also.
1. Extra Weight.
2. More Amp Draw - Lower Voltage setups are going to draw more amps to produce the same amount of wattage output at the motor(s). Which brings us to #3.
3. More heat at the motor(s). I've read where people who run this setup, say it runs hotter than what they think it should.
4. 1/8" motor shafts. Easier to acquire pinion gears, but the shafts are alot weaker than 5mm ones. I've seen more than one broken.
Give it a shot on the 20/68 gearing, but you are probably overgeared. Keep a close eye on temps to make sure you don't fry those motors. I would run it for a minute, bring it in and check. Then run it for another minute or two, bring it in and check.
Let us know hot it works out.  |
Update:
I just tried a pair of 3s Lipo batteries in my twin-Velineon E-Revo. I am VERY impressed with the speed! Its about as much as I can handle. I have 8th scale Crime Fighter tires and the balloon into saucers at full speed and spin on asphalt!! The highest temp I saw after a short bashing session with a couple wide-open-throttle runs was 142 on the motor and 137 on the two speed controllers. The Traxxas instructions say the motors should be kept under 200.
I appreciate the Cons...those are some things I had not thought of. I'll continue testing, but I need to go somewhere with a little more room because it is so fast I cant keep it at full speed for more than a second near the house.
