Very simple, quick, and cheap mod will improve performance of forward and backward movement. Replace tail rotor with the "bigger" Double Horse 9104 tail rotor and reverse power wires. This mod should cost less than five bucks for the rotor and shipping. I'm sure there are other tail rotors that will work just as well, this is what worked for me. I definitely recommend this helicopter, it's only about fifty or sixty bucks and it is very easy to fly.
Thanks for Watching !!!
