Foxcon Terrier 200
Have just finished test flying after putting on the Vgs at 7% of cord as recommended.
They have made a very noticeable difference to the low speed performance of this aircraft.
It certainly gets of the ground quicker and has increased the rate of climb by 200 ft/min.
Stall characteristics have not changed and they were very good any way. Stall has reduced by 5 knots with no flaps and 9 knots with 2 notches of flaps. Top speed and cruise appears to be unaffected.
Speed were measured on a 296 gps and tests were repeated four times in still air.
They give a very good bang for the buck.
I have yet to test with full flaps
