Bruce,
See this thread for an idea of getting flap motor from under the floor for better serviceability:

I'm planning on going this direction on my build since these motors are known to be problematic at times.
Thanks for the thread, it was a good read. But I'm a bit confused.
#1 it's not in the floor it's in the right passenger side boards, but it could work for an RV-6.
#2 it doesn't mention the motor drive or an alternative. Is there a more reliable linear drive motor recommendation?
I'm still waiting on someone who knows the linear drive details. ebay has a ton of linear actuators. I'm starting to do my own WAGs. This is going to start sounding like a 8th grade math word problem about moments... but here we go;
I measured the throw where one would install the stock electric as about 4".
From my own "arm-strong" flap history RV-3/4, it takes about 30lbs at VFE to extend a 24" lever. I measured the arm at 6" for the motor, that's 4x or 120lbs of dynamic load.
The actuators on ebay are typically rated around 225 lbs. So I think I've got it close.
So there are two options... Try to mount it more like stock in the middle, or try to install it up against the side wall per that RV-4 thread above, I actually like this way a lot, and I think I will pursue it first.
