I have the Just Flight Chipmonk . Reading AirdailyX review about the Chipmonk the man mentioned that he liked it but couldn't vouch for the fde .

The thought occurred to me about Bernt Stolles fde for the Chipmonk, so swopping and renaming the .air and cfg ( transfering the skins too ) I upgraded my Chippy.

I have just had a couple of good fun flights . Check it out and see what you think . If you currently own the JF Chippie I am sure you'll enjoy this .
