I modified my MM RC with antennas I picked up from ebay and did not really gain much from stock. The signal/antennas are finicky. One second full signal, next minute completely dropped signal. I ended up demodding and replaced the stock antennas and added a parabolic dish and have easily flown 12000ft from my home-point. I have just settled that this was never meant to be more than what it is. Plenty of people have pushed the package and lost this tiny-tot with plenty of evidence posted in this forum.
