Project OverKill (hehe)

[killajb]

With all due respect.. I've got quite a few 1/18 scale rc's now (8 of them) all of which are running on 3s or 4s. Attempts at "overkill" have often lead me to overheat instead. On 4s, Neu and Permax motors run cooler than any of my other motors and CC Mamba Micro Pro handles 4s just fine. Speeds at 4s running 4200kv motors takes a steady trigger finger and lots of wide open space. On 3s, Hyperion Y-22 motors(long can) are probably the best overall performance/cost option as they give you enough torque to gear up for speed and get relatively warm but not hot. I'm running a Quark Pro-Car and Dynamite Tazer speed controls without problems at all on 3s. If you can buy a MM for cheap, I'd keep it and use it for a larger application as it is simply not needed here. The Trinity truck isn't the heaviest 1/18 car out there, but it does need any of the above-mentioned set-ups to stay happy. Hyperion short-can motors(5000kv and up), Aon 6000kv, Wraith 7000kv motors all just made heat when I tried to push them in my Trinity truck.

As for batteries, I buy from United Hobbies. Cheap and available in different sizes and discharge rates to suit most applications.

It's nice to experiment with what-ifs, but at the end of it all, I think everyone wants a car they can simply charge up, drop on the ground and enjoy time and time again. Hope this helps.
