Rob, this is a copy/paste from my recent reply to your post on my YouTube version of this video. I have re-posted it here for the info of others, and to elicit any ideas.

G'day BB

I think I can keep the mech to one servo. As she is slightly tail heavy I am thinking of refabricating the front pivots out of aluminium and having some heavier duty carbon rods back to the main gear?

Cheers

Yeah that would help. One of the probs is the arm that connects to the nose gear. The grub screw is stripped & won't tighten enough. Maybe no "flat" was filed into the shaft it's on. The is a bit of force required to retract to main gear from their over centre position (which in fact, locks them down s they don't collapse with no servo power), so as the servo is pushing on the nose gear arm to retract everything, it comes loose. Zap has helped temporarily. TBC.........

@aviaterred PT 2. Don't think carbon rods are necessary because when the gear extends fully, they are all past the vertical...ie, nose gear points fwds, mains point back, so the weight of the heli keeps them locked down, even with servo unpowered. This means there is no tendency to bend the main gear rods. The prob you & Gaz had was the gear was never fully extended, so it tended to collapse under weight with no servo, hence bending the rods. Hope that makes sense. BB.
