Hello, I am building the fuselage for my 801. Does anyone have plans, drawings and specs for the no slot flap system? I don’t want to cut a big banana slot in the side skin if I can make help it. Thanks, Bill Phillips CH 601 XLB (sold) RV-8a (flying) CH 801 (building)

Here is a possible source, albeit CH 801 model.   Go to 8:50 for this mod.


Then go to PART 2 at 3:12 for the interior view.

Oops .  did not have my reading specs on.   Should not have used "albeit" .   Hope the link helps.   

I believe the owner recently sold that 801.   Gorgeous build and wonderful craftsmanship.      

Yes that is where I saw the modification, but I did some drawings or plans to replicate. Thanks, Bill 

Back in the old days, we called it the "Frisby-Haas No Slot Flaperon", named for the two guys that invented it.   I think I purchased the "kit" from either Jim Frisby or Ben Haas for my 801.  I'm not sure if Jim is still around.  Last address I could find: n801za(at)hotmail.com  JAMES FRISBY 5704 N FARM LOOP, Palmer city, AK 99645.  Ben Haas died in 2016.

Here is a good summary with pictures of the mod and all it's components:  http://www.liming.org/ch801/FHNSF.html

Two more links may get you to some design specs.

Scroll through this thread for email addresses:


and here a bit more recent - 


If you manage to get drawings, please post them here so this valuable information can be preserved.   Lots of times builders are solely focused on their own aircraft and forget the future builders who need their knowledge.
