Tony, if you have read this thread you will see that there is an early version of this plane designed for the DLE30 v1 and a later version designed for the
DLE30 V2. Since the V1 has been discontinued make sure you get the latest version of this plane. The difference is the length of the motor box. The latest version has a motorbox length of 3.5 in from the cowl ring. Look back through the pictures here and you will see a long and short box.
You want the short box.
