RE: KATANA 50 ENGINE SIZE
With a 61 flys like a brick, I mean a dead stick that happened about 40 feet up the plane only glided probably 20 forward before hitting the ground. A bit of a rough landing and the landing gear will snap (weight of plane too heavy) and hopefully it won't take the gear plate with it. I don't think the battery will be enough to balance it either. The one I knew of had 3oz in the tail i think with the battery sitting right at the back of the canopy area.
The plane that I'm referring to was later fitted with a Mag52 and a few things here and there to reduce weight. Flew great and really improved its glideability. Actually it took a bit of work to get it down to land after that and dead sticks weren't a problem. Seriously if you want fun out of this thing don't use the 61 and try to save weight everywhere. When the owner of the one has enough funds we are going to do another one but with at the light weight gear and lightening methods straight up. Should be a blast then cause this thing can fly really well.
And also with the 52 can side mount it and not have to cut a bit hole in the nice cowl.
