Well, I did a preliminary C/G check today with the wings attached, but no landing gear, T-can or canopy. The motor will also be moving rearward about 10mm. Using a 6S 5000 mah lipo I was able to achieve the proper C/G with the front of the battery about 6cm behind the fuselage former. I am pretty happy as it seems my efforts have paid off. Once I have the Apollo in RTF condition I will report back on the final C/G result and, of course, the actual flight performance.
