Giacomo, did you drop your man yet? I bought mine a year ago. Of the first dozen jumps, only 2 opened up fully. The rest opened up to some extent but were of course uncontrollable. I have just re-motored my Senior Telemaster with a 90 4-stroke. I also have installed an Eagletree Seagull wireless telemetry system to monitor the planes altitude. The final modification for this year is a FMA Co-Pilot to keep the wings level. When the plane was up over 500' and right over head the pilot was unsure of its orientation. It also allows the jump plane pilot to watch the jumpers descent for a while without risking diving /spinning the plane.

Hopefully I will get some successful jumps this season.
