I have a RedWing 30cc Extra 330 sitting on my work bench for 4 years. I started working on it and something always came first, work, house, you know on and on and on. So for the last three weeks I've focused on it and last night everything was done except to CG the plane. Last night I fired up my computer and searched online to determine where to CG the plane. (Note to self, I should have done this first.) I learned I purchased the first production run of the plane which is inherently TAIL HEAVY. I installed a DLE 30cc to keep the model as light as possible only to find out after the fact that I should have installed a DLE 35 to offset the tail heavy model. I moved two 3600 mah batteries into the motor box and it's still tail heavy. I have a TruTurn heavy spinner, so I replaced the stock carbon fiber spinner and it's still tail heavy. I have DLE 35, however, since the RedWing is no longer in business I would have to modify the cowl again and we know how that will look. I can use dowels to repair the motor box and fender washers to spread the load and install a DLE 35. I haven't used weights for years to balance a plane but I decided I've spent enough time on this plane and it's time to move on.
