I am currently flying the Matt Chapman 46 size with an OS 50 SX with an 12/6 prop. With stock fuel tank I am getting only about 5mins with 1/2 trottle. Sounds like the tank is way too small. I am looking to replace with a bigger tank only problem is there is a ply that barely holds the stock tank. Is anyone using a larger tank and if so what size and how did you get to fit in there.


Any help would be appreciated.
