Travelling much more than not so unable to get my CG/AUW notes. Plan to get a few days home soon, so hope to share details.

The big challenge I'm struggling with is access to wing bolts. Combination of large hands and pull-pull wires, results in so much frustration that plane sits on shelf. :-(

Cheers

Wing bolt access is not the best on the RV-4. I usually have to twist the rudder servo hard over so that my fingers can get down to the screw area. It's not perfect, but it's the best solution I've found so far.

Battery Compartment?


What is the length, width and height of the location where a electric motor battery will go? I'm thinking A123's here.

I would NOT worry about space for batteries! That's a 30cc smoke tank on the side and two flight batteries on the far left....TONS of space for your batteries. The battery tray measures ~10" by 5+" and is removable.

Thanks
Can you provide vertical clearance under the semicircle at the middle of the battery tray?

If my A123's fit, I may go this route for my Hacker A60-16M and its 19X12 prop.

4.5" from the floor. The battery tray lies on top of that a bit but I don't know how much.

So, per the attached photo, the vertical clearance at the arrow location is well over 3 inches?

(Standing on end, my A123 packs are 2.9 inches high.)

H'mmm
I have a Extreme Flight Turbo Bushmaster that also has its wing bolts located a fraction of an inch from the wing tube. Pain in the to tighten down. Solution was to take a 3/8 inch diameter wood dowel around a foot long, cut a slot in one end to insert over the wing bolt, and spin it on or off.

That works very well.

Wonder if that would work on the RV-4, but it would require a small diameter access hole on the opposite side of the fuse to insert the dowel. Or perhaps epoxy on a phillips screw head into a wood block, and epoxy that block to the wing bolt. Then build up a small diameter phillips screw driver with an extra long shank to screw it up, again needing holes on each side of the fuse.
