  1. Hi Erfolg,

    I think you should rotate the HK head 90 deg. left or right and arrange 1 servo at the leftside and 1 servo at the rightside of the mast.. Mixing the servo control as V tail or Delta.

    Succes.

  2. Trevor, remove the spats. With longer grass you can't get realy control the panther because a lot of movements occur you don't be aware of. I'm still in the hopping stage, my longest flight was 47 seconds and ended in a crash.

  3. Hi Tim, after some "trimming" hops these were the best flights up to now laugh. Everything is repaired, Waiting now for some nice summerdays without much wind.

    Maybe it will take some time and more repairs but I think I get this thing flying.

  4. Rich, José,

    Make the top from the sanding block(s), instead of ply, from aluminum, because after some sparts of sanding the ply will show some wear and your blades get thinner.

    I have just finished profiling my second set of blades, ( spares ) and for the next set i need to make new sanding blocks.

  5. Steve, I used VIVAK or PET-G for the canopy, thicknes 0.7 mm or 0.0275".

    I don't know a good source in your country, I bought mine in Germany.

    Pictures from my Vac forming rig you can find in the forum Hints and Tips,

  6. The postman has just delivered my copy of the June issue, but it's only half,

    I'm missing all pages between 42 and 51, and also between 82 and 91 and the pages 35 to 42 and the pages 91 to 98 I have double.

    laughIf some one has the pages I'm missing, I would be glad to swap them for the pages I have double.laugh

  7. This one I found a while ago somewhere on the internet, it's from a german autogiro builder.

    Here runs the drum in the correct direction.

  8. Big T and all other readers,

    I would never use the sandingdrum as in the video, he can be lucky the motor has little or no power and quits running as soon he puts the wood under the drum. If the motor was strong enough he was missing probably 1 or more fingers. Use of a sandingdrum ONLY when the drum is rotating AGAINST the feed direction.

    To make a drum like that use the same principle as Bill Pettit used to make his sandingblocks.

  9. Questions to the above post:

    Question 1: Which of the distances is correct?


    Question 2: I have the spindle mounted as in photo 1, distance to spindle mount center 35 mm, do I have to move my CofG now further back, to 28 mm or 23 mm instead of 18 mm from the front of the mast?

  10. Yesterday I saw a picture of the assembled rotorhead, when I compared this rotorhead with the parts on the drawing I discovered some differences.

    photo 1: Part HD3, distance to spindle mount center is 35 mm.

    photo 2: assembly drawing, distance to spindle mount center is 30 mm.

  11. Hi all,

    Thanks for the helpfull reactions on my question about the crash on maidenfligth from my panther. I think the most difficult thing will be to put aside the fixed winger in me as Bill Pettit wrote.

    Thanks

    Koen

  12. Hello All,

    Today we had super weather to maiden my panther, but the first attempt wend wrong.

    As soon she was off the ground, she rolled to the right and with a damaged propellor and 1 blade, so the party was over for today.

    Maybe the experts are able to tell what possible caused the crash and give advise how to avoid this next time.
