Wow .... seem the TRX3.3 engine really not tough enough, let see if I can run this 2nd one one better.
I also thought to use another brand engine but the more $$$ not worth and may heavier
I also have an issue now, the air intake hose to the carb is so close to the spur gear, can I find some aftermarket to change it since the original one is very easy to break and leak, dust will get through the break hole to the engine directly. You can see why I wrapped the hose (the white part in the photo).
I'm considering Castle Mamber Monster 2200kv since I tried similar thing in the HPI Vorsa this combo is powerful as Tekin RX8+2650kv I'm using now but with significantly better low torque performance, it can push the heavy Vorsa without any lagging feel on your throttle finger.
Anyway I will test drive the 8.2e with my current Tekin combo first, if handling not fullfilled I may switch to this Castle combo
