Have a sig kougar in my fleet also with a jett 50, turned into a tail dragger, built very very light and the cg is dead nuts. Have had this hot rod for 3 years now. NO!!!!!! I do not want to change the prop for slower landings. Leave the windmilling effect on my stinger 120 with a g 26. Just want to fool around and spend about 2 ounces to HELP SOMETIMES not over shooting the runway on a bad hair day. Going to do this, but was wondering from the start what size and where would be best. Going to try first on my trasher plane which is the midstar, a flap that is the width of the fuse and 4 inches deep inside the landing gear. Flaps I do understand should have holes to have more drag! Come to think of it! THATS what I want. Induced drag at a flip of a switch at a cost of 2 ounces with no computor or flaps. That alligator canopy is sounding awfully good!! Its in the ballpark anyways. My king kobra and kougar is what I really would like to slow down. Have slow and fast planes.These I want to keep fast In the air but not landing however. Is that why speed brakes where invented a long time ago? Thankyou again!!!!! KELLDOG
