I use a box like this to set up all the throws during assembly, that way you can do each servo individually and set the linkages up. Makes the radio set up a snap after you get it all together, well worth the $

Yeah, I've had two prop hub failures on my 38, one on each side. One at about 30ft so had plenty of time to turn in for a belly landing. The other happened right at rotation and had to just pancake in at the side of the runway. Other than having to re-glue both the firewalls and a busted vertical stab I only had to replace a couple nose gear doors. Not too bad considering.If it ends up looking too ratty I'll just replace it with a new one.

I repainted one of my Tigercats and was sloppy in keeping the fuselage control board protected and when I hooked everything up three of the flap servos chattered and didn't center or move properly and one didn't even work. I thought I had gotten too much paint on the servo's themselves and was about to order 4 all new servos but after I thought about it that didn't make sense. So, I did a little trouble shooting and bypassed the control board with a "Y" connector straight to the receivers and all the flap servos work like they should. All I had to do was replace the fuselage control board.
So, you may want to check if your control board has junk on the the pins or is itself bad by bypassing the board before ordering a new servo.

Hey rifleman-btx, I've had that experience before as well and didn't notice it 'til I touched down with similar results. What I've learned to do since then is to make a pass down the runway once after dropping the gear to verify that all the gear are down. Then if not, you can try cycling them a couple of times. If that doesn't do it, you can always make your approach gear up and kill the throttle for a dead stick in the grass. I've had to do this once and it saved the props, gear doors, etc. Brad

rifleman_btx, you may want to investigate if your nose wheel is rubbing up against the front wall of your retract bay sometimes when cycling. I had that problem with one of my mains and I ended up cutting a small channel out of the retract bay section it was rubbing against which cured the problem for good. Just an idea...My YouTube RC videos:

Hey rifleman-btx, you might also check for binding due to the strut getting bent back from a rough landing at some point. That will cause it to bottom out in the bay and stall the gear retract unit which in turn will cause it not to deploy on the next cycle. Intermittent problems are the worst!!! Brad

Those oleos are made from an aluminum alloy so I can't even begin to understand how you are breaking drill bits. What exactly are you drilling??
One of the more common robust aluminum grades is the 6061-T6 which does require a better strength drill in the Titanium class but in this model industry the material used doesn't even come close.Warbird Charlie
