Center of Gravity before maiden flight

       Remove this ad - become a site supporter!
I'm getting the CG adjusted on a new De Havilland Beaver build and the instruction say the range for the CG is any where between 2 1/4"-2 3/4" from the leading edge.
I'm just balancing out at the far end at 2 3/4".
Should I add some nose weight and get it closer to the 2 1/4" mark to be on the safe side for the maiden flight or leave it at the 2 3/4"?
Don't want to chance being tail heavy at all.

Re: Center of Gravity before maiden flight

Especially for a maiden, I'd say shift or add weight to get the CG closer to 2-1/2" or even 2-1/4". After a few flights, if all feels stable, you can always remove weight which will have the effect of moving the CG back to the 2-3/4" mark. A bit nose heavy, ie @ the 2-1/4" mark, is safer than tail heavy.

Re: Center of Gravity before maiden flight

I would prefer it to be nose heavy than tail heavy on a maiden.

I would definitely go for more nose weight to get the CG more forward. As you have it now, its at the rearmost CG- making it closer to tail heavy.
