If you have built the Hangar 9 Sopwith, then this question is for you. The specs show the Sopwith coming in at 7.25 - 8.75 lbs. I have installed an OS .61 for the engine and when I weigh the plane (no fuel), ready to fly, it weighs 9.18 lbs and it is tail heavy. This is with the battery inside the cowl and with the weight box and lead weight being used that came with the kit. However to achieve the correct CG, I need an additional 2.07 lbs. This will bring the total weight to 11.25 lbs exceeding the specs by 2.5 lbs. Have you talked to anyone who has experienced this same scenario or can you tell me if this will be "ok".
Thanks for your help,
