Here is an alternative that might work for those who want a little lighter tail.
If is from the free Hi-Max plans on Team MiniMax website.
I have a Hi-Max 1700R, which has this tail wheel and it apears to work well, My Hi-max on the weight and balance weighs 332lbs.
The aluminum tail has a nice spring action. I need to make a new wheel mount as the one from previous owner seems a bit small and is very close to the topp of the wheel.
Let me know what you think.
