There are a couple of Cierva type Gyroplanes in production (using a radial for originality).. Look great. But you have to to better than the video with regard to u/c design:laugh:

That is, of course, a bolt hole for a rod end, not a clevis.

Lol, then it's CASA for you my lad!

We all have. Thru' our RAA membership. The previous owner of my 19 reg. always had hull insurance.

only my head

so how was it the sump plug fell out? did the LAME forget to tighten it , then forget to wire it too ? Very difficult to believe.

That runs well with reliability based maintenance. When an engine is new the likelehood of failure is good. After some time the likelehood of failure lessens considerably and remains so for most of its life span (the "reliable zone") . ONLY if you don't mess with it.......... Everytime it's worked on the chance of failure goes up for a while, until you are back in the "reliable zone" again.....This clashes with some of the more common engines maintenance shedules. My thoughts? Observe and detect, ( I like solid lifters for that reason) don't do unneccessary work..get an oil analysis. Test compressions and leakdown, look inside the oil filter, look inside the bores, ....

Fantastic, but dont let the Iranians get a hold of the plans! (BTW, I flew in the trainer version of this!)

My Mitsubishi Triton just ticked over 4500hrs and it's on its 3rd set of plugs.

Look at still pic 1.06 minutes, clearly a model....when it's taxying no heat, from the tail pipe. What a joke, as bad as Kim dong's wooden rockets....Lol

how interesting!

I'm a fan

Congratulations

Luckily,by the time it would be built, I shall be too old to care, let alone fly......

Correct, it's near Lang Lang, apparently an air force base from the war.

Twins ? in RAA ? FFS

oh please match hole

Yes I know about "purge" I think its a poor choice of words...Probably translated from the German "säuberung" which means, in my German anyway, "cleaning" Cheers G

Anyway The remove oil pump and PRV and look at closely is a good plan.

Many exploded views but not much help. But lots and lots of warnings about priming/purging of the oil system. I would pull out the oil pump section and have a close look. Not a lot of tear down and easy access. Purge oil lines when you're finished. (whatever that means)...Cheers

weighs about 3 feathers, no effect.

I read through the whole story just now. I sympathise with you. What a nightmare. Most of your diagnosis efforts (and those of fellow readers) seem to be centered around the gauge(s) . I was thinking about it and came to the conclusion that the pressure does indeed flucuate! No amount of oil, filter, hose or gauge manipulation will change that. OK. The oil pump can hardly change pressure at fairly high speed.What retains the pressure on a Rotax?

Is the PRV at the "end" of the system or the begining? I mean is the PRV next to the pump or somewhere else?

I believe that you must look (again) at your pressure relief valve. I can't imagine anything else in an engine that will cause pressure to suddenly change. You wrote " Changed mushroom and spring" I assume that is the relief valve?. Did you have to lap it onto its seat? Is there some trick part that directs oil to the gearbox? Or jets that cause the pressure to be retained. (on a plain bearing engine the big ends and main bearings do this) On a roller bearing jobbie there must be a restriction that causes the pressure to be retained. Otherwise there would be none. I'll see if there is an "exploded" engine view somewhere. Good Luck.

I think the pilot in the VANS article mentioned above was really pushing the envelope when mounting a camera on the wing near the leading edge. Mount away from the wing please. On the wheel spat ? Great.

Quote from terryc ................ "We do have two distinct groups 1. Raa 2. Ga. Why for the love of god do we want ti fiddle with it."

I agree, you agree, so why are so many people ( see poll) wanting to change R.A.A. into Pseudo GA, with Cessna's Pipers, 760kgs? CTA , access to controlled airspace, Transponders, ADSB (probably) Aviation Medicals ect., ad nauseum?

Please go somewhere else and play ( in a nice way, of course)

From the poll you can see two distinct groupings. G.A. like, and Non-G.A. like. There's a good case to split the RAA into two groups and RAA can chase increased access and weight priveliges for those that want "G.A. Like" (non-derogatory! for want of a better description) and for Regs and Manuals and membership/insurance costs to reflect that. I really don't want the RAA spending my membership fees on chasing something that I have no interest in.I'm not "against"

anyone wanting more, I just don't want to pay for it.....

So the ribs are assembled onto the spar. Along comes the leading edge sheet (predrilled) clecoed onto the spar and ribs (keeping them in position) .And with straps and help it gets folded around and becomes the LE....... is there no internal support for the LE?. It looks very vunerable.

But I'm not familar with fuill size practice.
