    I find that working on helicopters is about two to one fly to fix. Fixing does not have an equal pace, but over time it comes out that way. It always comes in batches.

    A rotorway with the piston engine and belts was more like 5 hours work to get 1 hour flight, after the conversion to the T-62 turbine and drive line the trend reversed 5+ hours if flight to 1 hours work.

    "well the T/R gearbox mount had no support for the T/R torque loads so we used a dotco cutter and slotted the tube for cluster plates"
    Can you provide more detail on that, what tube are you referring and what is meant by "cluster plates"?

    "Main gearbox was soft mounted in an aluminum plate"
    Would love to see that, you happen to have any pictures?
    The rigidity/strength of that system in a tip over seems questionable.

    "added cluster plates at critical areas on the main frame"
    Where would those areas be and what is meant by cluster plates in this context?

    Thanks for the input.


    The old original frame always looked structurally great to me (definitely not the yellow) and found the better cabin shot.

    HAHA, so true, I purchased the Brantly because I was sick of working on the Helicom soon to discover that the only thing changed was the aircraft being worked on.

    A cluster plate is a flat sheet of 4130 put into the tubes to reinforce a set of tubes coming together at a welded joint, see the Bell 47 frame for details, the yellow frame has clusters of welded joints but no reinforcing plates.

    the pic shows a cluster plate on the gearbox mount of the EH 1-02 (the triangle pieces lower left and behind the rope)

    OK got it, have always called them gussets but now understand what you are referring too when you say cluster.
    Thats a good idea and I'll do that.

    Thanks

    Here is a good example to clarify.

    The main rotor blades on my Mosquito are to be replaced at 500 hours. I lost the paper work on them but I think they were made in Fla.
    Tail rotor blades are carbon fiber no tbo

    Chuck,
    You have any close up shots of the Mosquito tail rotor?

    BRS on a helicopter is flat out stupid, going from controlled flight to uncontrolled is not too smart.

    As for catastrophic failures a BRS is of little help.

    wires and CFIT accidents are #1 cause of helicopter accidents, cruise flight accidents less than 3% of totals.

    not worth the added weight.

    Very grainy Chuck, can clearly see what it is but seeing any of the T/R detail is not happening.
    One of the problems with some phone camera pics, they look perfectly crisp on the phones but this sharpness does not always translate to a PC monitor with the same sharpness or perhaps you optimised it too much before posting.


    How the heli doing so far?

    NO ballistic parachutes. Autorotation with full controls works better than no control with a parachute.

    I'll take some better pics and post later today. The helicopter is good, I've only had one problem with it so far had a cdi go out on one flight
    Hirth sent a new one the next day at no charge and payed return shipping for the bad one. They had a recall on the cooling fan it looks like they had a few bad ones in the same lot#
    The new fan is on and ready for the weekend. No ballistic parachutes for this guy
