Ok first, I'd like to say hello to all. I've had my RC for a little over a month. I've already learned the wrecking stages. Already went through a handful of parts and about 1.5 gallons of fuel. First question is this. At the local shop the seller has a Hot Bodies .18 motor that will fit into most ".12 and .15 mounting spots". Will it fit into my RC10? I don't have any mods done yet except for the RPM replacement A-Arms for the front, since I trashed the right one last night. I want a little bigger engine for some bigger tires. And possibly some other things. Now he says that the HB motors are "iffy" and the chance of getting a good one is about 50/50. Is this true? And if so, is there any other types of motors I could bolt into my RC10 without doing any serious chassis moding? (more than .15 if possible) And, as for replacement parts, on to my next question. What parts should I replace on my RTR, for "quality" reasons. I learned about my A-Arms the hard way and saved more on buying the RPM replacements instead of the stock replacements. What else is there that I should replace before I trash. I already am going to buy a set of RPM replacement rear A-Arms. Blue as a matter of fact. I got new ball cups for my steering and camber assembly, RPM heavy duty of course. What else should I look forward to replacing? And just a couple more miscellanous questions. Is there a cool dunebuggy-ish body for the RTR? Can I get a 125cc or something close fuel tank for my RC10 without chassis modifications? Is there any other system of connecting things such as A-Arms to the mounts other than the pins and E-clips? (Something that can take more abuse than e-clips) I think that about does it. Heh, sorry for the long list. Just been wondering and couldn't get an answer.
