Volfy,
Seems you have my problem: You just gotta bash a kit do ya? Yep, I added flaps to my Hobbistar too. Flys with authority with the .75 Tower engine. Monokoted the bottom of it in hot pink too, so I have no orientation problems. (My eyes aren't what they used to be with them Houston overcast shadows up there).

Now my Tower 40 Trainer resembles more of what I saw in your photo: After a minor crash I totally stripped it and rebuilt it. I also did flaps, bolt on wings, and I also removed the plastic end caps on all surfaces. Must admit I'll probably never use the flaps again on the Tower 40. Tried it once....talk about floating in with a balloon landing!

Which club you frequent? Spacecity, NW, Sparks, Scobee ???

Stick,
Just for arguments sake, don't forget to add another 2 lbs of fuel to make my plane 20 lbs. ready-to-fly. You're right that the 2.1 Moki should handle THIS plane just fine. (Precisely why I sold my brand new unrun Saito180 GK I originally planned on using and deliberatly chose a 2.1 Moki instead) But if this Moki were to be put in a 20lb aerobartic plane, I doubt the maneuvers would be unlimited. I would have preferred a little more powerfull engine to provide an extra margin of thrust, but didn't want to go to a gasser for this model. Anyway, I'm glad we're in a debate on how well it will perform, instead of how poor it won't. Ok, your turn. But please leave out the subject matter, and just start arguing about nothing, then I'll be much more comfortable. (-Cause then it'll be just like being home with the wife. But I'll promise not to call you Shirley)
