I recently bought a bunch of Falcon wood electric props for my new toad, figuring that they were the flavour of the month for electric F3A boys, how could I go wrong?
Well, for my purposes I thought they were junk - high amps to get about as much handle feel as a wet fish, compared an out of the bag knock-off APC from hobbyking at a 10th the price. In fact, I depitched that ugly Hobbykunk prop from a 12x6 to a 12x5 and it's the best prop you could ever hope for at $2.73.
Also, just quietly, Turnigy (from hobbykunk) beech gas props seem to be dead ringers for J Zingers, I had a 16x8 Zinger on my 1/4 scale Cap 10b, swapped it for a "Turningham" (as my 83Y.O. flying buddy calls them) and I couldn't see any appreciable change on a tach, or in the air.
