Just finished my Losi 5B Electric build and took it out last night. I launched it off some small hills near a park and ride, and ended up cracking the rear wing. It's pretty much a goner. I was thinking that it'd be nice to replace it with something sturdier, so the occasional roll doesn't affect it, but haven't found anything. Any recommendations? The other issue I'm having is that my Castle BEC 2.0 WP seems spotty. I'm driving it off two 4S packs (28.8 volts) and have it stepping down to 8.25 volts for my dual Spectrum 9020s for steering and a 9010 for an e-brake. I was getting unexpected steering and brake loss after only a few minutes of running. I suspect that I may be overheating the BEC. The 9020s whine a little. Could that be causing the BEC to run hot?
