Has anyone looked at putting a slightly bigger fuel tank in the Joker? Im looking at buying another Joker but I only have a KT 120 to put in it, (can’t afford an Ultra flash) but don’t want to only fly for 4 or maybe 5 mins, i’m sure this has as good a fuel economy than my Wren 100 I had in previously but I’d like to get at least a 6 min flight. Anyone know of a bigger tank that might fit? I wonder if CM Tanks could make a slightly longer tank.
