The propellers look like they are fairly efficient for mini rc use...they are made by hobbico too...so that's a good sign. they are 1 dollar each at the local hobby shop.
parts of two full balsa wood planes.
im going to use the infra red pcb(great range) from the Key RC that i posted about yesterday. it has extra channels on it..making it perfect for
prop,rudder,lift control aerlons or dual prop and rudder..or whatever works the best.
