what engine would you recoomend, ive been wanting to put a jett on it but dont have cash so i was going to use the .75 till i could get a .60-.70 jett and start pooring lead in the tail. as for the firewall, i intended to fiberglass it and the forward part of the fuse unless there wwere objections to doing so. whats teh thrust to weight going to be onn a plane wit hthese specs?i kind of like how the .75 is cheap since this seams to fit my budgeeet more at the moment. but i would prefer a more powerfull engine what would fit better.still not sure about the nose gear, may have to buy a heavy duty nose retract?? not sure. anyway. how fast do you think it will go on the TH75 vs the jett50? for a little less than hallf the price id be more inclined to do the TH if the speed is close. btw i hope this is the case, itheres no foam or plastic parts is there? that just takesaway from the fun of building.
