My proposed plane
Your have made some wise choices! I have no experience with that particular radio but I have flown the LT-40 witht a Thunder Tiger .46. That is a great combination. I have several TT.46 and have them screaming and have never had any problems with them...ever! I converted my friends LT-40 to a tail dragger and put flaps on it for him. It flew so slow you could walk up to it on final approach and grab it and set it on the ground!, also with the flaps down and the engine at idle you could put the plane on final and set the transmitter on the ground and it would float on in(no wind of coarse). Speaking of wind, this will be the only draw back to the LT-40, it is such a floater that in a decent breeze it will be a little more work to get it to settle in. You will be able to grow with the radio and engine you have chosen. Take your time and ask for lots of help, no questions are dumb at this stage of the hobby, it could save you a lot of time,money and headaches in the long run and most importantly, have FUN!. Feel free to e-mail me any time if you have questions. Good Luck
