Hi Eveyone
I have done a lot of searching regarding moving the seat back on my RV4. I have just started building the fuselage so am trying to plan ahead.
From what I can find on the net most people just say move the roll bar back 1 to 1 1/2 inches, and this is where I get confused with the following:
1. Does one simply move the roll bar backwards, or must the F405 and F406 bulkheads also be moved as don?t they give strength to the roll cage mounts?
2. Regarding the bottom of the seat, does one simply move back the seat back hinge?
3.Will the roll cage now interfere with the canopy frame, and if so how do we get around this?
4. Will the aft stick need to be modified to get full movement?
Sorry for all the questions but this mod is definitely something I need to start planning for.
Thank you for any help
