No they dont mike... My Nova Bf21 is still very new but even fresh off the track it wont roll over... Even my severly overheated NR528 is difficult to roll when running in the correct temp range...

Hey traxxas... Where the head bolts loose???

thatsd what i was thinking cause thats what happened to my friend....but i dont think so.

but for now on im putting my own thread lock on

oh shit...you know what i think they might have been. not severly loose but when i took it home they werent hard like they normally are.

but they still seemed decently tight, so i dont no.

I know how to tune and i know it couldnt have been overheated, because the temps were fine, it saounded good, and i have never fried an engine from being too lean. maybe the head bolts were loose enough to do this

FYI NO LOCK-TITE ON THE HEAD BOLTS. YoU WILL NEVER FORGIVE YOURSELF IF YOU DO!


That is all. lol

what ae you talking about dude?

If you thread lock the head bolts then you'll end up stripping them and they're a PITA to get out when stripped.

yep, no loctite on head bolts, he's right.

ok......then ill make sure theyre real tight

Actully thread-lok (blue) when heated past like 200 degrees breaks down, So techincally theres no point in using it..

Really? Wow...Well just to be safe (like if you had to tear down the motor before you drove it or something) I still wouldn't do it lol..

roc it will break down, but those threads are so fine and crappy that the dust and junk from the threadlock ends up making the screws tough to get out unlse the engine is hot and then u strip the heads.......I did it about 4 times as a NOOB hahaahaa

I use loctite on my carb cinch nut and my backplate.

True true.... The aluminum does strip easy , and then you need a new block or a tap kit!

same here tex.....my carb nut always strips out after taking it off and putting it on a few times
