I purchased a Turmoil on Friday and it is now Sunday.
It did not take me 2-3 hours to build.
I got the thing because I didn't want to spend time cutting out Depron...now I think cutting Depron is actually the better way to go. I also think I need to go walk on a beach somewhere....I am a experienced builder and now question my abilities. I agree with others that the instructions were poorly written. The basic engineering concept of the snap on hinges is good, but idealistic, barely practical and takes patience and agility of a watchmaker to install. When you are ready to "snap on" the ailerons you might also "snap off" something...I did! IF you get the ailerons on, you will then notice that the control horns per instructions mechanically conflict with a pair of wing struts! The whole feel of the aircraft is "brittle...brittle...brittle." This brittleness is worse in my opinion, if you use only "foam safe" CA. I used epoxy in many joints, of course the argument is it adds weight but maybe a wee bit more weight will hold the thing together instead of have it fall apart. I am not going to use their control horn idea and plan to use off the hobby shop shelf wire pushrods and nylon control horns.
