ok well thanks to all for putting in information to me about the motor. I guess what i will have to do is get it running well enough for flight and start experementing with prop size and fueltank placement and all other suggestions.... i got it to run well with a 16x8 and 17x8 apc... which were a whole lot lighter then the dynathrust 18x8 i had it turned well and i wasnt getting the fuel problem anymore so its a start. Now for 3D i think this motor will do well enough to get me starterd... i agree that there is no replacement for saito and YS but for a poor college students affortable is what i was after. I will post as i begin to get it in the air... and let you all know how it is going... i will also put up a video of it when i can for all who want to see some performance with this motor on the funtana 100 and i will make sure to give to all specs as well when i get it finally weighed and all. Thanks again to all for the help i would have been lost without it!
