CG check.
Hey guys, help me out here just a second.
I'm building a tailess plane powered by a .15 and I need your help verifying the balance point.
36" span
8" @root
5" @tip
2" sweep @tip
I'm thinking I should balance it at about 20% MAC
using http://www.palosrc.com/instructors/cg.htm
I get the result of:
MAC: 6.62" @ 8.31" from root
Balance point @root chord: 2.25"
When I plot out the CG location it doesn't look right.
I would appreciate if someone better versed in the science of aerodynamics could double check my work please.

RE: CG check.
I can use some help. I'm buliding a 46 size pusher using a Pica Touche kit for the wing and using the kit tail moment. I am having to build a long nose to get the C/G at the proper location on the wing, [Stock C/G on stock Touche plans,] My question is with the long nose [24'' in front of the LE.] Will I have to move the CG forward?
