world models cub
I flew the Cub for the first time today. It flew great. I ended up putting the OS 40 FP 2 stroke on it. It was the only one of the three engines that I had avaliable that the LHS had a pitts muffler for. I could not justify buying a new 4 stroke engine when I have 5 or 6 engines laying on the shelf that are not being used. The 4 stroke will come later. It turns out that the FP is the perfect engine for this plane. It has plenty of power and flies scale like at about 1/3 throttle. I have other tail draggers so taking off was no problem. I just eased the throttle on and kept it tracking straight. I had to give it a lot of up elevator to get it off of the ground. The plane also required a lot of l right trim. I had to run it almost to the stop to get it to trim out. I flew around for about 15 minutes and then landed. When I inspected the plane I found the right wing twisted. I will try the heat gun and see if I can straighten it out. It needs washout from the servo out. The twist is very noticable when looking at the plane from in front of it. I wonder why I didn't see it before. The plane flew good anyway but needed alot of trim to fly straight. I will work the problems out and fly it again later this week.
