Arm Rest Interference

Posted on May 1, 2011 at 12:50pm 3 Comments


Is anyone having issues with the back of the armrest sides being approx 10mm higher the the tunnel top panel when installed.


This problem has been dogging me since joining the rear and front fuselage. All other parts and pieces seem to line up just fine.



Any help or comments would be greatly appreciated.

I saw a picture of Conrad Watters 750.  It looks pretty good.

Thanks for the reply Leo.  It looks like we are both right and the Homebuilt Help video that I used as a guide has it wrong.

Now I can work on replacing clecos with rivets before the snow flies here in Iowa.

Best Wishes ...  Fred

I meant "drawback to having the gear channel flange outside of the fuselage"

Hi Leo

How did you fix the "arm rest interference" problem? 

I had the same situation and fixed it by clecoing the aft flange of the gear channel under the rear fuse instead of inside.  That brought the rear of the arm rest sides down to fit perfectly.  And I didn't need to use brute force to place the seat bases between the rear seat channels and the lower baggage floor.

Now I am trying to determine if there is any downside to having the gear channel flange inside the fuselage so I can start drilling out and riveting.

I will appreciate any information.

Added a discussion about the Jabiru that might answer some of your questions about it.  Feel free to contact me for any add'l info.

Deburring is important but check out this tool, it may make the process much easier: http://www.yardstore.com/browse.cfm?viewfrom=13&catid=334&step=2

The tool deburrs both sides of the hole at once.

Ditto Leo on the Demo ride on that Friday for me. Most impressive was the stall characteristic - flat and gentle - I wouldn't have know if he didn't tell me we were going down (pays to watch the altimeter).
I finished inventory last nite and have all the parts in separate kits...finally.

Leo ,
The stretch through North west Ontario looks like it will need a way point at Fort Francis --for sure.
So far I have flown with Angus in his 750 for 3+ hours.It is very responsive and feels particularly solid ---for a fellow who has enjoyed flying Challengers for the last 10 yrs.
no doubt you have seen Angus' pirep

Leo I do not see my reply re: corrosion protection.
Yes I will be covering any and all exposed metal. My plan is to be on floats in fresh water. Ultimately I would like to fly to all coasts --east, west and perhaps north, if I can manage it. Conrad
