that sucks, I had to go to a seperate gyro ( ripped my eflite HH gyro off my walkera ) after a collision with my brick house.. LOL luckily my 4 in 1 didnt fry, but the piezo sensor for the gyro seperated ( the chrome part in the top left corner of the pic) came off. thats more $ i didnt want to spend. Wish i could find somewhere that sells that part to replace it myself so i can free up my gyro for my other heli again.

Also, if your reciever is still intact then you can still use it even with the Eflite 3 in 1 combo, it would just mount more akward then a new reciever due to the plugs on the back of the reciever for ch 3 and 4
