Hey everyone : )
I've been learning about the Cozy Mark IV for years now, and I'm trying to make a CG/ weight and balance calculation but having a hard time. I've found various spread sheets that compute it for a complete aircraft, but I'm trying to find out the distances (X axis only) between the tip of the nose, the front wheel, the rear wheel, the CG and the fire wall.
I've read up on the details of engine weight vs position to attain the original cg, (Link) but I'm trying to calculate a ratio, specifically, "Shifting the engine X inches back will add Y lbs weight capacity to the front seat".
Understandably, shifting the engine back will necessitate more nose ballast when flying solo, but as long as the total CG/weight and balance remains in the stable range everything should work. Yes, shifting really far back will make takeoffs/landings more difficult by decreasing the distance between prop and runway on rotation, but to me its worth the trade off. My wife and I together are about 450 to 475 lbs, and we do everything together, so no way is she taking the back seat on this.
Can anyone here provide these dimensions?
Nose tip to front wheel =
Front wheel to rear wheel =
Rear wheel to CG = ( not sure if target CG is before or aft of rear wheel)
Rear wheel to firewall =
Any help would be appreciated...
