TGY are pretty thin too, or is it TGS. GC are the same as Hobbyking? If so yeah, they're prob what you're after too. Check them out tho as they're reported as some sizes being inaccurate, i.e. 6x5 is 6x3!? On the 2836 2300kv motor the 6x5 pulled 10a less than a APC 6x5.5, so somethings not quite right. But not all sizes are out. 5x5 is right for example. The Graupner 6x6 should work IMO. When I did tests I'm sure (could be wrong tho
)that it pulled 4-5a less than the 7x5 flightline prop. Granted tho the 7x5 had more pull if that's what you're after.
