I have to disagree with you goinstriaghtup,
Rule of thumb overpowered ANY plane is better then underpowering it.
I have a Kadet and because of the weak engine on it OS .40LA its really hard to take of and perform simple maneuvers. This is actually prolonging me to solo (i so i like to think, lol).
Also if you do go with a LA (i would at least go to a .46 with this engine) Youll only need 5-10% nitro not 15% thats just a waste.
For the .40 trainers i would get either .40 or .46 in a ball bearing engine (yes the TT is a ball bearing engine) for two reasons.
1) They give more power
2) More importantly they last longer. I dont know about others but i personally want my engine to go through as many planes as possible.
I personally regret buying the .40 LA and much rather have gone to the .46 fx and just taking very good care of it so i could pass it on to another 3 or 4 planes.
I dont have time to read all the posts so if this has been siad im sorry,
Yes all those planes you have leasted fall under the cateogory of ARFs and theyre also all under glow.
