3D MOJO 65 w/20cc Build

[Alky6]

I am thinking the valleyview or dle 20cc. I currently have a DLE 20cc on my other Aerobeez profile and it does great, but can be a little persnickaty (if that is a word) about fine tuning. I am used to it though so no big deal. I have read so many great things about the VV 20cc engine.

Ha ha, yeah, word in my book. I have the vv20 and the 40. 20 has yet to be run. Been sitting in a box for a couple of years. Looking forward to getting it finished. Wings almost done now. Just have to add the rib caps on the bottom and then finish of the ailerons.

Hi
Im new on this forum and just foud this Mojo 65 build thread.
Just finnished mine with a Ys 110, works great.

Nice looking plane and welcome to GSN. Nice somebody else with a YS. I am presently flying a AW pro 260 with a YS 120 love the combination and for anything less than 30cc I still prefer nice four stroke glow.

Wings are done (sans ailerons). Pic is of the right wing.
Weighed some things up at this point:
Wings and wing tube (sans ailerons) - 21.02 oz
Fuse - 29.85
Tail pieces - 5.01
Engine complete - 32.58
Total = 88.46 oz or 5.5 pounds.
Not too bad at this point. Still need to make some landing gear out of aluminum & find some light wheels.
Shooting for under 8 pounds.

Are you going to use carbon fiber rod for wing tube, or aluminum? I have aluminum, but not sure as I have had aluminum wing tubes bend before. I just basically have to hing and cover mine at this point.

Aluminum wing tube. Bending - might need a bigger diameter? What kind of hinges are you planning on using?

I think you will destroy the wing before the tube bends in this plane. My 55cc edge profile has a 3/4" wing tube in it that is aluminum. Would rather it be aluminum as well. Would rather the tube bend and me see the wings with dihedral in them over a CF tube that will break. Under too much load and in 10 flights of wringing it out I ain't bent it yet.

I was going to use Robart pin hinges cause I have a lot of them, but changed my mind and will go with Dubro flat hinges. Once you drill a hole for the Robart hinges there is not enough meat left to suit my tastes, so the flat hinges will do.

I think you are right about the aluminum, although I have never had any issues with carbon. The aluminum tube is certainly a lot cheaper. I was looking at the wing tube sleeve and aluminum tube should hold up fine for this setup.

As for hinges I like the pinned hinges as well and normally just add another block during building as a hard point where each hinge will go.
