Below is a link to a W.M. SS60/180 that I stuck an Saito 180 on and sheeted the horizotal stab wih 1/16 balsa. I also built a new vertical stab and rudder. I installed a 24 oz. tank ans a 16/10 APC prop on it. The vertical is completly out of site and it will hover all day long at less than 1/2 throttle. This is a fun airplane to say the least and has now flutter at all because all surfaces are sealed. This plane is just a hoot to fly and I really was having a great time yestarday...I let 5 people fly it and all agreed they MUST have on. I have an O.s. 160 that is going it the one I have in the garage sitting in the box. The plane very easily handled the 180. I wish you could see the 180 haul the 10 lb plane from a dead stop in vertical....it look like the space shuttle.
