Hi guys I recently bought this edf off a friend I believe it's the 55mm version not sure on brand. Anyway not realising it was 55mm I ordered 2 50mm Dr mad thrust 4s from HK these fans if I remember are 27amp and 690g thrust or close to it. Fans have been fitted and connected to a watt metre. On full throttle the metre is showing 50amp draw and 750watts The model weighs 1450g with a 4s 3000 60-130c Lipo installed. I could use 2200 4s to reduce the weight slightly but that would change the cog. Retracts are not fitted so it's hand launch only. If I put the model nose down on the kitchen scales full throttle it shows 650g Do these figures tally up as to wether this model will fly once I launch it or come crashing down? If held vertically there is not enough power to hold itself up or anywhere near it, none of my other edfs do either come to think of it but they fly well. Thanks
