The heavier servo just slightly ahead of the CG, the esc mounted between the cowl and the bottom of the slot for the power pod, and an 850 mah 3 cell placed into the space of the power pod gives me spot on balance that I can adjust from 1in to 1.5in as recommended, not to mention a sweet looking plane that is more durable and FAST (I'm using the Emax rs2208s, 6x5.5 HQ prop, and YEP 30 amp esc). During the wing building I used heavy coffee stirs and very fine gauge music wire to make my own flexible pushrods so everything is concealed (No unsightly servo sticking out the tops of the wings. I mount a 12 gram metal gear servo cut into the top of the wing just above and in front of the spar in the center section.

(Adds a little more weight upfront and looks the part). The cowl just didnt look right as designed (in my opinion) it ends up with a conical or truncated look which the corsair doesn't have so I modify the cowl to form a cylinder and laminate it with the rosin paper twice, radiusing the front edge by pinching and bending. I make the fuselage and empenage as per the plans. Makes everything MUCH stronger but doesn't add a ton of weight. Put it on the paper (the rosin paper, let it dry, put it on the foam and let it dry then use a cheap iron to iron it on. I remove the paper and relaminate it with red rosin paper and a slightly watery mix of regular white glue (PVA with a little food coloring). I always start my builds by modifying the DTFB. I've seen a lot of comments about the CG issue and I'll share what I did with mine that leaves it spot on, super fast and steady, and a blast to fly.
