Bolink Econo Rail Dragster

[pipeous]

A buddy doesn't have his account setup here yet, so I am posting this for him to get some advice from the gurus here.

He picked up a Bolink Econo Rail Dragster and is planning on tossing his newly modded mamba max into it. He exchanged the caps for some 470uF (I added 4 of these externally to mine) as my bud flipped his brushless revo without a lid and one of the caps got road rash.

The guy that modded it goes by The Steve on forums. He does testing and such for castle as far as I understand. I do know he makes spektrum rx's, a lap counting system, and a drag timing tree, among other things. Pretty good at the electrics.

Anyway, he wants to do some speed runs with the timing tree and was going to toss a 3s lipo and a 7700 in. Steve told him they were tossing 4s with a 7700 in drag cars and getting 100mph....

I thought 3S was going past the motors max rpm?
