bem, I contacted TOPMODEL after seeing the Dalotel link you provided with questions about the weight of the aircraft shown on their web site. I believe it said 13 to 14 kg and contacted them because my math was coming up with a very heavy model. TOPMODEL replied to my question that the all up aircraft would weigh 28.5 to 31 pounds<-can this be right? I mean a 60cc engine will not pull that heavy of a model.

Thanks
