Rebuilt a crashed yak54 profile... looking for placement of landing gear and where to spot the cg. Could use a manual or some help! Thanks everyone !

Use a flashlight to look for landing gear holes just in front of the LE wing at the bottom of the fuse. CG, start at the tub and adjust to your liking.

The plane has been rebuilt from tube forward, I have no holes to find ! I was hoping someone could give me a measurement from the tube to the bolt holes...

Hopefully when it was rebuilt, there were hard points added where the gear need to go. You don’t want them too far forward or back. This is the RadYak I just finished and this is where and I would put the gear. The gear should be angled forward about five degrees. Put a piece of tape on the fuse, draw a line square to the bottom. Hold the gear up with one hole in front of the line, top hole behind.

Be patient and let me see if I can find the plans. I have a scratch built one.

My wings attach with one center nylon bolt accessible thru the wing hatch... I think this is the right plan tho... close enough right??

Looks like I have the yak sp-55m, Not sure how the yak 54 sticker got on the rudder, but its coming off !

Have that one too but never did anything since I didn’t like how the ARF flew.
It did have some 1/4 pieces of plywood glued to the fuse when I got it.
I’ll see if I can find the plans, unless Mo beats me again. :mrgreen:

I would guess a mount for the pipe.

Sorry, forgot about this, let me check.

I have figured out that I have the yak sp55m, not the 54 ! Previous owner had slapped on a yak54 sticker on the tail that doesn't belong !

Nothing on the plans, I’ll start at 40% of the root cord.
Doing some more research to see if I have the manual.
