Hi guys, I'm new to nitro RC. I started with a redcat earthquake 3.5 which I broke in then bashed the hell out of. I just received my revo 3.3 that I bought used on eBay. The thing is an animal. It has a decent amount of aluminum upgrade parts and I added a roll cage since I don't like running bodies. I took it out to a church parking lot to get it tuned.
First issue was that I had to richen it up significantly from factory settings. High speed runs were running way hot and not much smoke at 4 turns out on the HS needle. Once I got a good HS setting I played with the LS needle until I got it doing wheelies off the line. It was idling too high at that point, even with the Carb gap around 1mm. I richened up a little bit and got a nice idle but no more wheelies.
Any advice on what I should have done differently there?
Now the main part of this post. Once I got it tuned I began screwing around jumping the bark mulch islands going way too fast
. I found off first hand that I need practice with control on jumps since I was landing on the cage more than the wheels. I probably had the biggest smile ever though. Until of course I noticed the pos cage was starting to bend. I kept driving since I had the factory plastic engine guard on still too. Of course I jumped a grass section, lost it pretty bad and ended up upside down on the pavement. Suddenly the rpms shot up and it ran full throttle until it stalled a couple secs later. I inspected it and found that the engine head had hit the ground. This stress cracked the motor mount on the frame side and engine side. Somehow the motor pushed into the spur gear which ate through the air filter tube and into the Carb. Somewhere in there the Carb snapped off at the base causing the rpm spike and stall. So picked up a new Carb, spur, and mm. Also am switching back to the factory air filter from the motor saver.
Does anyone have any advice on this engine setup? I really don't mind things breaking because I bashed them, but I don't want to lose an engine to external damage.
Sorry for the long read...
