Could one of you World Giant Scale (GS) P-51 owners help me with a CG question? I'm just finishing up a World P-51 GS and the CG seems way off. The instructions indicate 6.9" or 175 mm behind the leading edge "where the wing meets the fusealage." My problem is as-built, my plane is currently at about 1 3/4 inches ahead of that point! I've never seen a nose-heavy warbird like this and I'm a little stumpted. I've built the plane with an inverted Moki 1.80 (yes a little big for what the plane is spected for) with an aftermarket Pitts style muffeler on a 20x10 plastic prop. All the servos, fuel tank, etc, are in their correct locations as specd in the instructions. In the nose I've included an in-line fueler valve and a remote Ni-starter connection so I can connect the glow battery on the top of the cowl. So, I don't think I've added any appreacble weight.

I would appreciate any feedback on the actual CG's from any of you guys who are successfully flying the World GS P-51.

Thanks
Eric

Mine is balanced per the dimensions you list - it flies very well there. I use less travel on the elevator than they recommend. For landing i put expo on the elevator on all my warbirds - from -20% to -35% depending on the plane. since I have futaba radios the expo is negative. the expo makes the elevator less touchy on landing.

Thanks for the input rc34074! Did you find it necessary to add a lot of tail weight to achieve the correct balance?

This motor is a ASP 180 so is quite a decent size, its well hidden under the very nice 3 part canopy... It has a set of vents in the front of the motor and air can exit out around the rocker cover however I am considering using my tools to remove the fibreglass from the inside of the exaust stacks to give more air flow... what do you think? The rudder and elevator control wires are installed and work nice, I have included a little ackerman in the controls as well..

This plane is I guess a very plain Jane model but to be honest very very well made

I have my world gs miss america ready to fly but haven't flown it yet this year. I'm planning to fly it some as is with the stock super tiger 2300 I have in it, and then I will change the 2300 carb to a walbro wt499 carb, which will let me invert the 2300 and still run it on glow fuel. I have already tested the walbro on the 2300 and it works great on this engine with the same 10 % Omega fuel I usually run in the 2300 now.

once I have all this sorted out then I will strip the covering and redo it as a WW2 version. I would like to find a new set of the cowls for this plane - anyone have a set they would sell me that is not cut out yet?

Anyone know if a SuperTigre G-3250 is adequate for this plane? Has anyone had any experience with this engine?
