- 300+ flexwing (pendulaire) newly trained on gyrocopter ((autogire)100h)
Morning folks.
I am now the proud owner of a Deluc Gyrocopter kit fitted with a Negrowsky (negrowski) rotors and a BMW K1200RS engine. Just at the final part of my Gyrocopter (autogire) training here in France and soon hoping to have the beast ready for the first run up later this year. I hope to replace all the nuts and bolts with new aircraft standard fixings, and replace the bearings in the head etc. Not sure all this is absolutely needs to be done, but, it's a question of personal confidence, changing them all will force me to check everything as I go. Also, I am a little mechanically minded so a deeper understanding of all the parts can only help.
Sizes etc should not cause too many issues, measuring the existing fixings and confirming the holes sizes hopefully should lead me along the right path. Are all aircraft standard fixings imperial sizes ??
The torque settings for the fixings I am not sure of. There are some big meaty bolts and I am guessing they will need a fair amount of torque, example the head and rotor mounting bolts.
Cadmium plated or stainless steel bolts, which are the better and why, I rather like the "looks" of the stainless steel, but, as my wife tells me when I'm looking woefully in the mirror "looks are not everything"
I read or heard somewhere a comment regarding the rotors and their cleaning, mine are resin, that one should only clean then with water and a gentle soap and never add a polish as this will make the rotors "too slippy" in the air and reduce their lift. Confused, I thought that making the rotors more slippy would reduce their drag and therefore improve their lift, am I missing something.
I will be posting lots of questions, some will be seen by some as silly or daft probably, but if i don't know or understand I would rather ask and look foolish than not ask and be foolish.
Looking forward to your learned replies.
Merci et Thank you
Phil
