i can see [ hopefuly im rong] a few bent machines comen from this mass hangn thats required.Im all for it, but i think theres a safer/easier way of findn your COM.Specialy wen sum members wouldnt let their neibours within coowee of their gyros, never mind hang it. And sum real deperived underpriviliged typs would have to supply a few slabs to git thir mates over, and the contents of the slabs would kinda defeat the purpose of askn for sum "safe" hands.Then there are the ferels who dont have neibours. I agree about possible machine damage Birdy. Before the double picture method I used a Chuck Beaty exl spread sheet. Much easier to do when the maths have been done in the spreadsheet. I am not smart enough to attach the spread sheet here so I will paste the US forum link.http://www.rotaryforum.com/forum/sho...?t=26856Aussie Paul.

"it would be very handy for those who need to move their COG up or down"It surely would. Been wondering how one would do it. Suck it and see was the only alternative I could think of.Graham

Ok just stole this from the Yanky site, it would be very handy for those who need to move their COG up or down, it allows them to find out how much you need to move so it should be right the first time.Thanks to Stan Forster for this formulaCG shift = percentage of weight moved X distance

Whatever percentage of the weight that you move.....multiply the same percentage times the distance moved...and thats how much the CG moves.Example.....You weigh 250 pounds....and you and your gyro weigh 1000 pounds. If you move your seat up 4 inches.....how much does the CG move up?Simply multiply the percentage of the weight moved....in this case 250 pounds....and this is 25% of the total...... times the disance moved.....which is 4 inches up......and your CG moves 25% times 4 inches...or one inch.Another example....you weigh 150 pounds....and you and your gyro weigh 1200 pounds. You raise your seat up 2 inches....how much does the CG raise? In this case...you are moving 150 pounds up 2 inches....or 1/8 of the total weight. You move your self up 2 inches....so your CG moves uo 1/8 times 2 inches...or 1/4 inch. Stan You neeed to keep in mind that if you have the seat tank, you need to add the weight of this also i would think

the home page has a heading of instructors with a "yes colomn." Could be worse, could be "yes colon".Graeme.

Have used a similar method myself. Was lucky enough to have the use of a mechanical workshop with a floor pit. Have also heard of people using their trailers for elevation.

Another way I have heard someone doing it is dig a trench (Yep probably a farmer) and tilt the gyro back into that with the mains still sitting on the ground.It would have to be wide enough for the HS to fit and would have to be done on a very still day so the reference string doesn"t sway around but still doable all the same.

Shot the bentnec yesterday and retrieved me mag. [ duno where the mailman went ???]First orrf, top efforts from the ASRA crew agin.Second, i can see [ hopefuly im rong] a few bent machines comen from this mass hangn thats required.Im all for it, but i think theres a safer/easier way of findn your COM.Specialy wen sum members wouldnt let their neibours within coowee of their gyros, never mind hang it. And sum real deperived underpriviliged typs would have to supply a few slabs to git thir mates over, and the contents of the slabs would kinda defeat the purpose of askn for sum "safe" hands.Then there are the ferels who dont have neibours. IOW, theres a way of findn your COM, on your own, without any risk of bendn your bird.You gota hang it from sumthn solid to get your hang angle, so while its there, do a double hang.While its still off the floor and youv gottn your dangle angle, simply attach an endless chain or winch of sum sort to the same point you hung it from, attach the other end to the nose sumwhere and pull the nose up so"s its hangn at a nose high angle [ same angle as it would if you were balancing on the mains.]Take anatha pic, with the suspension rope in view, same as the dangle angle pic.No more risk to the machine than the hang test, and you can tell ya mates to buy their own p1ss.

Were you talking brail or was I just reading it that way? ???

I think that is a not good, cause the gn didnt have me in it, and if this comes about i have to start training again.

[asra]

Keith, I will run that idea past the Board and see what everyone thinks.Sounds good to me.

[asra]

I recently received my Winter 2010 Gyro news, thank you.At this stage I have only "flicked" through the pages, however I note on page 39, the Instructor List seems to be missing the headings for all those little ticks...which made me think; rare thing for me to do!We should have a Gyro News tab on the forum where errors, ommissions and correction can be published so we don"t have to wait for the next issue.I would also recommend the tab be a read only, no "posts", and that any suggestions be directed through and posted by the gyro News Editor only...Your thoughts and comments appreciated.Keith.

[Greg Mitchell]

Got my GN mag today....very interesting read.Lots of work by a dedicated few. Big effort.I wish the ASRA Board every success with these new initiatives.

[asra]

Now thats a bit embarrassing . Have changed the spelling.

Very clever, would have been better if I had of thought of it though.Graeme.Maybe you would have thought of it,,,, but you WERENT UP early enough
