Hello! New to the boards here... I have an older Traxxas Nitro Rustler that came w/ a .15 on it... IT was okay until we wanted more power... and wrecked it a few times. Months later during winter we installed a used engine from a friend of mine, was a Megatech 2.6cc engine... now, I am not really an expert in the hobby yet, so if I make a mistake or two I apologize This engine moved good... SOmewhat lower compression (can turn by hand) but it ran, only problem is that it will not stay running, but when it does the thing runs fantastic! I am having trouble finding parts for this engine as my LHS says they are discontinued. Brings me to my next point....

I picked up a broken-in TRX 3.3.... 3.3, meet Rustler! I want to do this swap, and I want to do it bad. The 3.3 is used but only 1 quart of fuel ran thru it, still sounds phenomenal. My dilemma is this... Not knowing a whole ton about these yet and only having done two engine swaps, I want to know if there is anything I need to know about the 3.3 swap onto this chassis... Is it worth it w/ the single-speed trans? Should I bother? Or, should I swap the 3.3 onto the T-Maxx 2.5 I have here, and put the 2.5 on the Rustler chassis as that woudl probably make more sense.... IF I decide to go w/ the Rustler 3.3, are there any walkthroughs online? I didnt find any via google...

Thanks!
