Terry,

Try a APC 12 1/4 x 3 3/4 prop. You get heaps better throttle/thrust control and the plane doesnt fly real fast. We found out about the APC prop's when our club held the state pattern championships. Some of the pilots were using real cheap trainers (they reckon if they crash, for $120.00aus, they just get another one) for 3d fun during the breaks. No-one could beleive they were hovering etc using .40's and .46's etc in these trainers. Turned out the trick was the prop!!!!!!!Of course after that, most of our club members raided every hobby shop in close proximity for these props... Even my really heavy arrow became a pleasure to fly!!!!!
