I have a backlit M8... i got it with module only no servos. The Airtronics part number on the box is 90281TX27. TX27 means it has a 27 meg module in it. But ordering it from some other supplier will not let you use this number. Most suppliers have a different number than the factory part number. You are probably best off getting on the phone and calling Tower Hobbies, they are usually pretty good at giving you correct information, even if you dont order from them.
...you better run like im booger flickin...
