Concept CG

I have a Concept Models FLeet Biplane, the smaller one.
It is gas powered.

I don't have the plans handy, (would have to find them).
but the the CG can be guestimated by
taking the max thickness point of top wing and max thickness
of bottom wing and drawing a line between the two points.

Halfway (front to back) would be the approximate CG based on the two wings.

Works best for me when I balance mine right on the rear cabane screws.

Just checked my plans for 1/6th scale Concept Models Fleet Bipe:

3" from top wing leading edge (25%) for trim flights
3 5/8" from top wing leading edge (30%) once airplane is trimmed
4" from top wing leading edge (33%) - Do not exceed

Hope this helps.

Jeff, have you flown yours at those CG's? I was having a terrible time trying to land mine when I first completed it and had set the CG according to the plans. I found someone that had been flying one for awhile, and he told me to set the CG right on the rear cabane screws. I did, and all my problems went away. This measures about 4 3/4" back from the leading edge of the top wing.

Of course, maybe some of my incidences are off or something, but it also worked for the very experienced modeler that advised me to move it back there.

Haven't even built it yet. Those are just the measures on the plan.

CG for Fleet Bipe

I have vintage IC plans by Bill Neukom showing cg in line with rear cabane strut attach point on bottom of upper wing and about 1/2 inch behind leading edge of lower wing.

Who sells the kit/plans you guys are buiding from? Would like to try one

Fleet Bipe

I built mine from a Concept Models Kit. I have flown it for about five years. I changed the motor set up lately and just forgot where the CG was . I thought it was at the rear cabane strut on top wing, but when I went back to the plans it didn"t add up. Thanks for all your help

Concept Models' Fleet biplane

The model was originally a construction article in Model Builder, contact Bill Northrop for a set of the plans. For the newish modelers, Bill created and published the magazine for nearly all its life, and now has the entire plans list available for sale. Look in Flying Models for his ads.

Concept Models Electric Fleet Bipe

I enquired and found that Concept makes a large Fleet for Geared AF 40 power. Wish they made a 36" span version for geared S400.

36-inch Fleet

You could alway purchase the Model Builder plans from Bill Northrop and take them down to your local friendly 24-hour copy shop and reduce them to whatever size you like. The airplane has virtually no sheetwood in it except for the foward fuselage - - - substitute strip balsa for the spruce called for in reduced cross-section and have at it. I think this would be a very successful model.
