Does anybody know the CG for this plane? Any help is appreciated.

Anybody?

Newman?

.

According to Peak manual it is 150mm from the leading edge.
According to the SDS it's 100mm. I maiden my on Saturday and 150mm CG was super sensitive.
On approach plane just sat there and needed down elevator to land.
All though wind was getting up to 37k/h so I'll try again when the weather gets better.

Thanks!!

My friend just calculated the CG in Auto Cad, and the calculations are at 4". I bet you are really tail heavy.

Let me know how it goes on a first flight.
I’ll give it a shot with a CG at 4’’ and a ¼ hopefully before Toledo.

I moved the batteries on the engine box and could only get to 5". I will try that.

I did the maiden today with the cg at 5" and it was good. It was still tail heavy, so I am not sure what I will do yet. I might put an aluminum spinner on it and try that. It flies nice though.

It is still a little cold out for my old fingers. Congratulations on the maiden. Sorry to hear you are having troubles with the balance. If I read correctly, you are tail heavy with your Mintor 38. I assume it would be even more tail heavy with a DLE 30cc. Hope you get it figured out.

Mostly in the way I set it up. I had the incorrect cg when I was placing servos, so with the wrong cg, the rudder servo balanced with it in the tail. I will probably move that to the stock location and do a pull-pull.

According to the specs, the DLE weighs 2.4lbs, and the Mintor weighs 2.2. The DLE30 would probably solve the tail heavy situation.
