i used a two blade apc, it probably toped off at 90-100mph (gear retracted) in a shallow dive, it fly's little slower dirty, for some reason my little ys dose not like the 10x7 prop i only got 14,500 rpm out of it, i'm hopeful that a 10x6 will get me closer to 16, i might order a 9x7 zinger, but i never tried a wood blade to try to achieve speed, i'v been flying low and slow gas 3-D all summer but this little nitro jet has thrown the speed monky on my back.
i can't hardly wait until Friday, in fact i think my big planes will stay home all weekend.
