Daren, I look Forward to Video!

Enterprise, do you have a document that explains the RPM to thrust formula's? I would love to try them with my Torque MK II on 16x7 Xoar

I have the same spreadsheet from PE.R

Hi guys, I was wondering what are the Max throws in High Rate for the Rudder, and Elevator for this plane? And I know, its as much as you can get right? I am just curious what the max you can really get without it hitting the opposing control surfaces.

Thanks guys, AKf

You have to be careful with the elevator. With too much you can get a cam over due to how close the pocket is to the horn. You get plenty of rudder throw, just that it is undersized compared to the crazy ones we see now and with the long fuse you do not get crazy yaw authority. 1.5 turns on a pop top is about all you can ever get from what I have been able to do so far.

You can see how close to cam over you are. I use a 2" arm and the forward spline to stop it.

Just redid my setup with Ty McCormack and we managed:
Elev- 46 deg, rudder- 48, aileron- 50. With Ty's help I got 5,5 and 8 more degrees out of it and the performance is great. PTs get 1.5-2 turns and 3 D is much easier with the wing staying stalled throughout the rollers with the increased throw. When I want to "spin a plate on a stick" doing pop tops I grab the 60" Laser!

The post with the three attachments don't work. The over cam image shows, but can you tell be how many degrees of of max thow the rudder and elevator.

Let's try this again.

Realize you hinge them yourself so it is possible to get 90 degrees up with enough gap. The linkage won't go that far. It had enough pitch authority for my tastes. Needs more rudder. If I ever get really really bored in the winter one could add some meat to the rudder aft.
