I have had around 10 flights now with my Wind S50E and cannot believe how well she fly's, She's very stable at all speeds, Take offs, Landings and Rolls are to die for, In the right hands the P11 Schedule is a breeze, (not by me i might add). The Build is very stright forward with very clear instructions, Everything fitted perfectly. She was set up as per instructions and hardly any trim adjustments were required. If you are thinking of getting into Aerobatic's this would be a great place to start. This is my first Sebart Kit and 1 would not hesitate in recomending them to anyone. Thanks Bill, Quality Products and Quality Service.
