Now its 5100 gram, but i use a aluminium spinner from Protech and it weight about 94 gram which make it nose heavy and i have to put 80 gram in the tail to have a proper cg. Was looking at a 65mm spinner from DuBro and its weight is 46 gram, if i change it to Dubro i will save 48 gram in nose and could take away 80 gram in the tail and only there save 148 gram.

So with some thoughts about equipment it would be able to get it about 4850 gram i guess. But it flyes with almost unlimited power vertikal with todays weight. Im using OS 140 RX and Hatori (OS pipe) and 18x10 APC prop. I had set the pipe lenght 15 mm longer than the recomendet for max rpm. This gives more torque and definitely more silent engine.
