You feel you have the right to come acccross as the be all and end all..
You dont fly with heavy pay loads - Chopper jockey does,
i understand what he is trying to do,if you disagree FINE that is your right...
You were advising him to put much bigger blades on machine and change a rotor head, on machine that is belt driven and is similar size to my hotcat, if he did indeed follow your advice he would have had blades smashing into his tail blades.. you never advised him on a precaution of flying with big blades, or that he would have to change his boom and tail drive if he put blades over a certain size,
You just made the point you fly with 1/4 scale machine using 2.5meter blades, which is not helpful at all as it is a different machine all together, bigger size frame, bigger main shaft, and that it runs at a head speed he has just upgraded from..
he was asking the question what does he need to do to be able lift with his jetcopter..
I have flown with Bell bloke who uses a Hawk for camera work, he has also done tests on on his predator turbine lifting a heavy bike, they way he got round using a smaller machine was to increase the blades size up to 850mm that gave him a lifting capacity of around 30/40lb..
He also sped up the tail using a 14-13tooth gear, to cope with the heavy payload, this is a far cheaper way than what you are recommending,changing rotor head, etc...
The above that i have recommened will cost him about $300 max,and he can keep his current machine which he is very happy with, your method will cost him considerably more..
That is why i said increase your blade size to a point, cos at the moment he is flying with smaller blades, i also made the point that the biggest he could go to on his jetcopter is about 850mm/900.., using tapered blades will give an equal amount of lift... and help out with a heavy payload..
that info is correct, is it not ? it is just different to yours and as always you feel threatened by my comments and have to come on all aggressive... GROW UP.
