I'm in the process of installing the slotted flaps from Airframes Alaska. The slotted flaps are a bit heavier than the ones I built from the D&E kit. There were a number of problems because I had built flap and aileron hangers of my own design to accommodate the D&E flaps and ailerons, but I have worked out all of the problems but one. The flaps are too heavy for the flap return springs. The flaps will not fully retract. The springs that I am using I procured from Univair, so I'm looking for a solution. Stronger springs would be the obvious way to go, but I don't know where to get them and I don't feel like having them made at the local spring shop.
Any suggestions, anyone?
