hi, only got one battery pack at the moment, so thought I would give it some pre flight checks and just a gentle hover.
This was a pre built heli so did the usual visual and mechanical checks, and noticed the tail rotor was not moving fully across it range.
Had a look in radio settings and servo set for 100% travel, thought perhaps that is all that this one needs, WRONG the blades span up clock wise and the whole heli span anti clock ways. This on 1/4 throttle further investigation found the culprit, the guy who built it had forgotten to tighten the tail servo bracket to tail boom and I missed it too
So I found the position on tail boom where the servo arm was at 90% and tail rotor in middle tightened it up and gave it another go.
Tail rotor slider now moved equally both ways, so up the throttle and it lifted up to a great hover at about five feet, noise was awesome.
No room to do any flying in garden so brought it down again, my hands where shaking by this time anyway the noise and power from it compared to my little king will take some getting used too.
waiting now for some more battery packs before taking it up to the field, to say I am like a puppy with two tails would be an understatement.
