trim trouble after a crash

[tppjr]

Had a crash yesterday, hit the a sprinkler pipe in the ceiling at work, took out the main blades, sheared the shaft pin, broke the 3020 DD prop and broke the DD motor. After getting it all back together it wants to go backwards, full trim forward and I still have to hold a fair amount of forward elevation to hover. Swashplate looks level and all servos are still at 90 deg at zero throttle.

:dontknow Any ideas?? :dontknow

Someone has to have some idea.

A n00b here, but if all linkages are correct, is the battery in the same place? It could that the centor of gravity moved back...

One other thing...Did the frame crack possibly? That could cause the blades to lift (and pull backwards) if the break was in the right place...

Check all of your ball links, some may have hair line fractures, you will have to take them off to find the culprit. You may also have damaged a servo, make sure they have full movement.

I think I might have found it. On the alluminum swashplate where the pitch servo ball is was bent out a bit. I straightened it back up but was not able to test fly since the 9C's battery was dead from using it for the TRex setup.

Getting close with the build but will still have to wait about two more weeks till the BC-6 comes out so I can charge my batteries.

Man I am a lousy waiter :bawl

Thanks for the help, I will post tomorrow after the flight test.
