Are you flying your tiger stick as a tail dragger or trike? If trike then switch it out to Tail dragger and fly it some more If your already flying it tail dragger ask yourself this question... can I do any better with this plane? if your greasing your landings EVERY time(ok almost every time), keep it tracking straight down the runway during take off and can do ALL the basic aerobatics with it your ready to move up... in this case a 4* would be a very small step up... the tiger II would be a bit more... personally I think you would be ready for something like the spacewalker. The seagull arf spacewalker fly's VERY nice with no real bad habits on the ground or in the air... it will take a bit more skill to handle than your tiger stick set up as tail dragger BUT not that much more. You seem to be looking for something that looks like a real plane(scale) the spacewalker fits the bill and makes a good 3rd plane... yeah it's only your 2nd BUT you you started out with a 2nd plane


Good luck with what ever you choose
