I'm not going to race but I just read on the instructions it says "It's designed to be strong enough to handle Nitro .12 or .15 engines"
What do you think? I have an OS .18 in it
Now I'm thinking I should have got the heavy duty one. Should I email him and exchange it? That might be kind of difficult though.
I guess if you look at it this way. I've been taking it pretty hard, and if every other plastic part on the RS4 is holding up, this should.
