The incessant desire for something new can be a nuissance and waste of energy and time. I ran a five-year old LST2 last weekend, with a stock Losi 454 engine, and had a blast.
It's a hobby.
Most people can barely get the maximum power out of the engines they already have(myself included). Most .21 engines are actually overpowered for racing - the trick is to reduce or tame the power. That however does not mean that nitro engines should be made "easier". It's a hobby, and should entail a learning curve. Real hobbyists I think don't care how childishly simplistic plug-and-play electric supposedly is. No matter how you spin it afaic, brushless is still like watching paint dry.
Long live nitro. Even if next year I have to run an RTR .28. I'll have fun with it.
