im not switching losi, i had over 10 tanks replaced by the factory on my rc8 all of them with internal air leaks, i never broke a tank, they would just start leaking after a few tanks on the track, basically would start leaning the engine out during the race, wasnt to good for the engine, factory kept replacing the tanks but didnt offer any compensation for the engines that were taken out by the tanks, im gonna switch to one of the traditional 1/8th scale brands like mugen or kyosho
