Don't let my problems with ST affect your choice.
I have not owned that size Super Tigers mine were all larger.
The worst being a G90, idled beautifully and plenty of power at full throttle but could not get a good mid range, I dead sticked just about every time I flew it. I have read threads were people have replaced the carb with an OS carb but I couldn't find a direct replacement for the G90, Don't remember where I saw it but there is a cross refference chart for replacing ST carbs with OS carbs and just about every model was on there except the G90.
From all reports on ST the biggest problem is getting them tuned in, from what I have heard not all ST models are as picky as with everything in life you can get good ones and bad ones.
