Thomas,
thanks for the offer, I wished we I had known before but I have been working on this quite a while. All the parts are now being CNCed by a friend in WA and a wing mock up will be built to try the retrofit process. The correct pintle angle and rake is built in and will bolt to the main spar.
The down lock parts are for the A and D models though not for the 152 and will be driven by a linear servo.
VG, I will try Carr see what they have.
