Does anyone know anything about or has anyone had any experience with the thundertiger 120 rear pumped motor.

I know it's no OS 140, but I have one on hand and am looking at slowly getting back into pattern after some 3 years absence.

My last plane used an OS 108 on a pipe with a cline pump. It seemed to hold its own with the 120 4strokes.

If anyone also knows where I can get a header for it that would be much appreciated.
