ow...sorry......
not only the rex rer12s3 but also the novarossi NS series.....rc concepts......
as I said before.......running 16% nitro JP engines are nothing but crap......
don't know about running 30% nitro....because the engine won some important races in USA, but here in Brazil, specially at the world championship, I saw every motor regardless of brand simply kigking every JP asses.....
lot of brazilian drivers that started the championship running JPs has switched to other brand........
not even jean paul calandreau was able to make his engines at least competitive........
