Seems we are all suffering same problem. All our hits occur at approx 100ft+, regardless of s/c, d/c or pcm rec's. Everything seems to point to the radio.
As i said earlier sending the 2 units back twice to model engines(the importer), and repeated scanning of the field has resulted in no difference.
Most of what weve tried is original hitec equip with original crystals, usually straight out of the complete flypack. Frequency is making no difference at all.
Worst part is we all love the feel and programming of these radios, as Mossie said we just want them reliable.
We are losing members, and word is ... Dont buy hitec!! Surely this is going to lose retailers business? Bad news travels fast, as we know.
I am also flying heli's still with radio, but theres no way i'm going to do circuits until problem is found.
Also found (as smoothpass stated), digital servos intensifies problems. Why do we get lots of sevo jitter using 525bb/645mg/9525 servo's but not 422's? Tried 1100+1500mah packs(4.8 & 6v), no difference.
X-JET, would love to know results of your shoot out. Next we are going to try jr. vs. hitec on same model.
