Anyone tell me the recommended CG range on the DP 120 Ultimate? Just picked one up from a friend, sans instruction manual. DP website will sell a manual for $5.00, but has a $10.00 minimum order. I sure don't need two of 'em.

Thanks.

The CG range marker I put on my upper wing is 5-1/4 to 6 back from the LE, but I wish I could figure out were I put my instructions! Why don't you just call and ask Dave? I have always found him helpful.

The instructions say the cg is 1/2 to 1-1/2" forward of the rear cabane on the top wing. As with all planes start at 1-1/2" forward of the cabane and move back from there.

Thanks for the info. I ordered an instruction manual along with an extra canopy. A buddy confirms the 1/2 to 1-1/2 from rear cabane measurement. Sure is a nice looking, clean airplane. Can't wait to fly it.

when u start playing with your CG it still doesn't have any bad habits at the aft end of the range. 10 degrees of low rate elevator throw on this deal.
