The X & Z engine dimensions are wrong. The engine must be moved further ahead.

Dimensions are in inches and weights are in pounds.
Total weight is item quantity times item weight.
(1) The amount of fuel is too little.\
(2) It will be nice to pull the pilot back further; by ??(bringing the engine and radiator further forward)??
(3) The CofG is too far aft.
With the one pilot etc. this value will be closer to 0". It should probably be approximately -4", with average load. Move the Power train and Rotors back 1 - 2"? Or preferably, can the engine be moved closer to the firewall? Put more of the equipment under the pilot's seat.(4) If the pilot weighs 180 pounds then the CofG from Origin on X axis is
???"(5) The two-seat version is only the trainer
(6) The maximum weight for
European - JAR - VLR is 600kg (1,320lb). The maximum weight for US Sport Aircraft is 1232 lbs.
