It's rather funny. in another thread I gave advice on things to check for a truck that didn't move. I blew 2 of those things myself yesterday.
every rc needs things fixed from the factory, pretty well. 8th scale buggies are the toughest I will admit. I raced them for many years for that reason. that said, 2 seasons ago was nitro hell for me. I had so many motor problems throughout the year, and I had really high end (expensive) motors that were custom ported and stuff, and it finally did me in for nitro.... the roar race, all weekend thing. I bet I spent 12 mins on the track actually driving all weekend. not bad for my $45 entry fee. the roar prez was my pitman lol so can't fault him.
that stupid motor would either run 300 degrees and blow glowplugs... or 1/8 turn richer and I couldn't make a 5 min qualifier without running out of fuel. he was putting in a third glowplug in the main when I said stop, enough is enough. I raced nitro for many years, and I loved it. The challenge of tuning, pitting, tweaking was a huge draw for me. the last few years, I didn't want to fight as much. I was the rc pro director last year here and I couldn't make all the races. I kept the points, posted them, got amazing prize sponsorship (I myself sponsored all the trophies) and I got complaints that I didn't attend all the races LOL. ya I run my own seasonal business. that did it for me. big scales here we come diving in without checking the depth. it's good cuz I can only fit 2 big scales in my shop.
I converted an 8th to brushless last year and ran that. sold it year end and bought a redcat 1/5. I had my semi and was putting it together. we ran 1/5 through the winter. no way any little rc was going to hit the track when we were up there. we had a lot of snow, and when some melted it was muck. an rc is dirty when you have to pull out the pressure washer

.... that is what draws me now. run and run.
I think people need to remember that these are really heavy rc's. they aren't meant to be jumped like 1/8 buggies. The draw is no tuning and fuel economy. able to go over more terrain than the little guys. they don't adjust attitude in the air like a 1/8 (I could go off jumps upside down and still be able to land on my wheels by hitting the brakes, no way with a 1/5).
