I should add on my LT-40 I'm using a Super Tigre GS40 it has a lot more power than the OS Max LA series and the price is a lot more atractive. For the radio I went with a Futaba EXA 6 channel its programable and once you trim out the model it storres the settings and it can store settings for 6 models. The local club has had interference problems with other brands in my area. Check with your local group they can advise you on radio and frequencies that work best in your area.
