Hi folks. My First post.
I built myself a E-Revo by using some parts out of my Trex-600 heli. An align 600XL motor (1700kv) and the Align 75A ESC. I used the pistix gizmo to make the aircraft ESC work. I made my own motor mount. I kept the stock tranny and mechanical brake and even the reversing system and optidrive. I built a carbon shelf on the right side which holds 8S A123s. I relocated the receiver, receiver battery, and optidrive to a carbon shelf above the front shocks. Surprisingly the left-right balance works out very well. The truck has lots of power and plenty of run time to keep me happy. Before I geared it down I clocked it at 48 MPH with Proline Road Rage tires on it. I also have a set of Moabs for it and have geared it down to more manageable speed. I really like having the two speed still working because I can do some nice crawling in first gear, then on flatter ground it will kick into second and really take off. I may upgrade to a Neu motor and proper ESC at some point, but this setup works very well and the align motor and ESCs can be found used very cheap… 60-70 bucks for each. Top it off with the $100 Dewalt battery A123 source, and you've got yourself an E-Revo with serious performance for modest cost.
I've found that the airplane-style ESC and 8S1P A123s yield very good performance. I think 2P would be too heavy. I get at least 10 minutes of bashing time with mine, which I think is good enough considering it only takes 30 seconds to change the battery. Better off keeping the truck light IMO.
Cheers,
Ken
