In search of a Bellcrank and controls to fit a Magnum

It seems as though my Magnum project has the incorrect bellcrank/mixer and isn't going to work as intended. Does anyone have a set they are selling? I am also willing to fabricate myself but I would need to get my hands on a set somehow to get dimensions unless someone has plans. I'd appreciate any help on this, thank you

Curious why you think it is the wrong mixer, or maybe how did you end up with the wrong mixer? Do you have any pictures to post that show the wrong parts and why they don't line up?

Hey Chris, the simple answer is clearance. The current setup has interference issues. What i have seems to be from a kitfox which has the elevator push rod down the center of the fuselage, whereas the magnum runs that push rod down the left side of the frame. Not to mention the controls I have are not mounted to the factory locations and other mounting holes have been drilled to accommodate. You can see in the pictures the bosses with the wire running through, that is where the elevator push-pull tube goes. The other picture shows how someone tried to run what i currently have, with the tube in the center. Not only does the stick run out of aft elevator because of the bungee support tube, but the linkage for the elevator does not clear as well. I hope that all makes sense.

That first picture sure looks something like the Kitfox 4 and newer mixer control.  JImChuk

Yes, I believe so. Here is a better picure of the bellcrank. Either way i need something to work, this just doesnt seem the easy way to go. This is why im looking for the original parts. Any suggestions would be greatly appreciated. Thanks

OK, I get it. I assumed you were working from a kit and could not understand how the parts that would not fit. I thought it might just be misunderstanding of how things fit together. I owned a magnum and spent a lot of time working on it and am very familiar with them so I thought I might be able to help.

Clearly those are not the right parts, and you are not building from an unfinished kit.  I understand now. Unfortunately I do not know where there are any parts you need :-(

Had i known you were that familiar with the magnum I wouldn't have gone into such detail lol. However I do appreciate your effort in helping me out. 

This is my first Avid or Kitfox, but i assume I will still be able to use the mixer I have if i can convert the bellcrank to function properly? Do you see any issues i might run into?

The magnum bell crank and mixer system is well thought out. I think you may be able to use parts you have, but find someone with a magnum, go look at it and take a ton of pictures so you know exactly what you are shooting for. I think it will help a lot.

I recently purchased a previously flying Magnum. No engine or prop.  The left flaperon had been damaged. Do you need pictures of the flight controls?
