Rob bought a 82" RTF Sea Breeze parachute and built the electric gondola from the included plans and says: "If it is to windy outside, take it inside!"
Here is what Rob says about his electric setup:  
I am using a 3s 2200 ma li-poly battery ( 140g) 11.1 volts
1500kv mega motor copy (cheep Chinese) of 480 size and a 9x4 prop or 8x6 apc-e props.
1 standard servo and a 25 amp align speed controller.
