RE: New to forum and Hobby
1st off, you have done a great job thus far. you have done your homework. too many people buy a nitro and expect to just fire up the motor and start beating on it.
even with fuels that say you dont need to use after run oil, i always did. afterrun oil is cheap, only takes seconds to put in the motor when you are done and will ensure that the motor doesnt rust.
i dont think the tornado's have much issue with the diffs(the 1/8 scales do tho)
still, since you are clearly someone who doesnt mind being detailed(good for you on locktiting and double checking mesh ect) you could pull out the diffs and use some diff lube or grease. im sure your local hobby shop can point out a good lub to use.
as far as the glow plugs, i want to say you should use a hot plug in colder weather. but i can never remember which way that goes.
i own a tornado epx pro(brushless version of the same buggy) the stock shock towers can bend with high jumps and bad landings. other than that, its a very strong chassis. and redcat does have billet alum shock towers(thicker than stock) that fix that problem.
seriously, you are pretty much on the ball, you have already done all the right stuff! many new to nitros fail to get a temp gun, or locktite or even follow the breakin procedures for that matter. glad to let hear its going well with your tornado, let us know what you think of it once you get to really open her up!
