It was good that you came back with the report even when the outcome was less than optimum.
BTW getting an underpowered warbird witn an aft CG back on the ground in repairable condition IS A RESULT. Mostly they go home in a trash bag.
Here is a RCU thread on the 95 discussing props.

IMHO it is a toss up between the 13 x 6 and the 14 x 6 in APC for your model.
When you have it on the bench look to see if you can move stuff forward. With short nose models I would often have all servos as far forward as possible up against the bulkhead at the back of the tank. The throttle servo can go on the side of the engine. The battery would get mounted on the engine bulkhead I have even fitted a small engine mount with long arms to the bulkhead and moved it to the front of that. [ Fokker triplane ] I really HATE having to add lead. Because light models fly better.
But better to have to add lead than to fly with a rearward CG.
