One bad revew does not make a lousey engine either. I've read a lot of threads about the RCV. My observation has been that those that own RCVs are mostly satisfied. Many have said that they've been very reliable too. Those that have had problems with the engine, have said they have received good service from RCV. They are different, and I have heard people say, 'not for me', but that doesn't mean that there is anything wrong with the engine. I am putting the .90SP in my TF Spit. If all goes well, and I am satisfied with the performance, I will use them for other scale projects for the unique advatages they offer.
