Alright I've got a bad bad habit of not leaving things alone...
After messing around with adding a PMR frame to my A4fly long ago, I was at the proshop messing around and found 2 old PMR frames and boards cut out for Prangle use,
(Prangle)
I found out they also work with the stock IMP solenoid, Well no negative side effects so far atleast. it really basically plugged right in and gives you all adjustable modes for the Classic IMP without buying another board,
Only bad part is you kinda have to mill the Proto frames to fit the trays, I actually think they fell very good on it. puts the grip slightly farther forward.
my next project is to make a Proto board work in the stock frame.
