Well I didn't have any of the above mentioned issues with the landing gear. When I installed them I could feel them snap into place real well & pulled & tugged on them with no problem. They are still strong as ever today. Make sure you know that they are locked in good though. I went over all the bolts in & around the engine compartment & found them all to be very tight & ready to go. The place I spent the most time, & this pays off well, is in hooking up the pushrod linkages to the control surfaces. If you take the time to get them adjusted mechanically it will trim out that much easier for you when the time comes & will fly sraight & true. Turn on your radio & move the appropiate stick for the surface you are hooking up. Move the stick back & forth, make sure the trim tab is at neutral. This will get the servo centered out for you. Then make sure the control surface is at neutral as well. I use painters tape for this. Just tape the surface to the wing so that it stays perfectly at neutral. Then adjust the clevis so that when you hook it to the control horn the control surface does not move at all. When your done, the trim tab on the radio should be right in the center, & the control surface should be flush & neutral to the wing, Vertical stab for the rudder, & the horizontal stab for the elevator. If you take the time to do this for all three control surfaces, you should end up with a perfectly aligned airplane that flys good. Hope this helps & good luck!!
