    Hi Geoff I have the latest and the early plans with the fuel tank on your lap will tray to make a copy fo the CD tonight, did you have alook at the Photo of the rear of the fus what do think?

    Hi Phil the right side of the fus looks bent out and there is no stiffner at the rear l have doublers in that area.

    will take pics so you can compare.

     

    cheers Geoff.

  3. Hi Phil l have the 2003 plans if that's any help, l would like the CD let me know what l owe you you can PM me for details .

     

    l have got my bits from Zenith l am going to order some brakes soon from Aircraft Spruce haven't made up my mind which way to go yet .

     

    What plans do you have .

     

    cheers Geoff.

     

     

  4. Hi Geoff have you the latest planes and cd from Zenith? On the cd the progresive photos of the fella building his 701 it shows how he has gone all around the L angles with a crimping tool and put tension in the rear fus good or bad idea do you think?

    Hi Phil l don't have the CD l don't know why they would do that not sure of the benefits l know l put crimps on the radius not on flat surface.

    Put my main spring on today so l could wheel it around l had to clean up my shed sick of tripping over stuff l have to many projects on the go l am doing a rebuild on my 912 it had a broken oil ring its done 351 hrs no 1 cylinder wasn't running properly so l have completely striped the motor down new piston and rings new seals also l am putting a gear box on with a slipper clutch taking of the standard .

     

    Putting wing tanks in and putting the slat attachment plates back on so l have to un pick the skins .

     

    Heaps of work to keep me busy.

     

    cheers Geoff.

     

     

  5. I saw a Hydrogen "thingy" on a 4wd recently... How does it work?

    Hi Winsor l have had mine working for about nine months l have two cells working they draw 25watts you can regulate the wattage by the electrolyte concentration l use distilled water and caustic soda l carry three lites of electrolyte l have only topped it up every three months and put about 500 mls.

    The hydrogen gas passes through white vinegar to neutrilise the caustic then feed into the air intake my cuts in when l push the throttle l run my cruiser on cooking oil diesel mix and hydrogen and sometimes LP gas as well.

     

    here is a diagram of how it is produced

     

    cheers Geoff.

     

     

     

  6. yep i do have a cigarette socket charger, i will bring that. I might still investigate a solar charger or a portable nuclear fission system/hydrogen generator or similar. :P all jokes aside, portable hydrogen fuel cells are already available, albeit at considerable expense and weight. Its only a matter of time until they are viable.I also wonder who will be the 1st manufacturer to make a phone or tablet (more likely due to size) with a PV cell on the back? Cases for ipads are already available with them, but they are around $200.

    Hi l run hydrogen fuel cells on my diesel 80 series land cruiser l often thought of putting one on 912 .

  7. Hi Geoff,That housepaint idea sounds very interesting! I have a few questions about that:

     

    Is that cheaper than paint normally used on planes?

     

    Is it lighter?

     

    Tell us a bit more about the hardener in the housepaint?

     

    How well does the housepaint 'bond' to the aluminium?

    Hi the previous own had painted it with house paint .

    l am painting it with polyu 400 two pack paint .

     

    l did paint a car years ago with house paint with hardner it was oil base paint it worked well but l will be using proper paint on my 701.

     

    cheers Geoff.

     

     

  8. Hi Phil l have finished make all the parts for my fire wall and nose gear and have started to rivet it all back together , will send pics when that part is done .

     

    l have imported my new control cables and swages l am using 7x19x 1/8 stainless steel cable .

     

    l have stripped all the paint from the 701 using citrastrip it is biodegradable and 3800 psi pressure washer worked well mine had been painted using house paint with a hardener .

     

    DONT sand aluminum you will encourage corrosion destroy the protective coating on the 6061 .

     

    when you get time could you take some pics of the Tyros engine free air cowling that l made a friend would like to copy it been along time since l did that .

     

    cheers Geoff

     

     

  9. Thoughts please, I have a 503 that i will be using in a tractor set up and it has always bothered me that the fan forced air cooling exhausts out the front of the tin covers in this application.I've read in a few places about people removing the fan and setting up a kind of air scoop and tin ducting around the heads and cylinders.

    As I have found nothing in specific detail of how this is made or perhaps bought, I'm hoping someone here may be able to point me in the right direction.

     

    Thanks

     

    JimG

    Hi JimG go Zenith CH-701 Thread post #32 there is a photo of my old Tyro with a free air 503 l will see if Phil will take some pics of the air duct l made for it year ago worked good.

    cheers Geoff.

     

     

  10. I hope your 701 project goes well (I have read bits and pieces about this on other threads). Do you find Zenith helpful in sourcing any parts you need?

    Hi yes zenith have all parts needed but l make most of the parts myself because its all aluminum aircraft its easy to fabricate parts, sourcing the quantity of aluminum is the hard part because you only need small amounts

     

     

  11. A big "silence" to this question SF1. I think the Zenith 701 owners who could give you relevant info are all too busy flying 022_wink.gif.2137519eeebfc3acb3315da062b6b1c1.gif

    Hi Eightknots that post was five months ago l have got my 701 and stripped it down the only way to find out the question is to do it myself.

    cheers

     

     

  12. Hi Phil mine is coming along slowly l am waiting for some rivets from Zenair and some other parts then l can start to assemble the fire wall.

     

    l have made doubles to put in behind where the main spring and strut attachment brackets are it is very weak in that area it does most of the work .

     

    Have you put a shim under the rudder hing bracket ,did you measure the rear of the fus or is it the bracket on the rudder itself it maybe on an angle.

     

    Is the thimble on the cable hard up against the swag on the bottom looks like it in the pic needs to have movement, are they gal or stainless cables l am replacing all of mine l make them up myself l like to use stainless cable .

     

    the swag looks alright like to swag the center of the swag to make sure l have the best grip we took some swages a few years ago to Morrabin airport for testing on there machine the cable broke and my sway stay perfect so l have done them the same way ever since.

     

    l will send some pics of my updates shortly.

     

    cheers Geoff..

     

     

  13. Geoff , is the bottom of the fuse bent down in your 701, the doublers where it looks like a carry through look odd?Met

    Hi Mat are you taking about where the hole is, that's where they put the battery it was 8.5 kg had no extra support it has bent the doubles

    l am going to replace them l am in the process of straightening the fus it is not square the whole aircraft has been out of square some sections have been loaded up the rear of the cargo area has split, it was in tension it must have been flexing on the ground and in flight causing the tear it was hidden by the carpet .

     

    cheers Geoff.

  14. Hi Phil thank also for the pics l have some from in side the fus for you they are different how people construct of the plans

     

    The Tyro looks a bit different than when l built it pod has change color different wind screen l built of plans 12 years ago does it still have the same 503 motor .

  15. Hi Geoff good mate ownes the Tyro has not been doing mutch with of late has lost conferdents in engine he is looking to repower her.I have to move the Tyro every time I take the club Jab for a run.Will have a look at zenith web site for VGs .I have done the same as you on the nose leg but cant get tension on my bungie but all the measurements are the same as the plans mite have to move the bungie pin down Cheers Phil

    Hi Phil l got a new bungee from zenair it is small than the one that was on it l was the same couldn't get enough tension so l made a new center section move the pin with the new bungee l had to use a breaker bar to lever it on should be plenty of tension now just hope its not to much here are some pics so far not quiet finished yet still some cleaning and filing to do but nearly there.

  16. Hi Geoff , I live and fly from Portland. You have some work ahead of you. Did you make the vgs youself? I have seen some home made ones that work alright, I fly a lot in a mates Savannah which has plastic vgs. I have spent a lot of time upgrading my front end, still not finished. Working on the oil canning at the moment, next week hope to start fitting the engine.

    Hi Phil l got the VGs from zenair it has taken me nearly a month to completely rebuild my front end l have modified it, it will be strong now l have made it out of stainless steel, l have a 750 nose leg l have braced it up to give it strength and have nylon bushing top and bottom and on the steering rods slides.

    l am going to try and stop some of the oil caning but it is awkward to get in the back of the fuselage .

     

    Is there a orange Tyro at Portland still ,l sold mine that l built years ago a police officer with one eye bought from me .

     

    cheers Geoff.

     

     

  17. Thanks Eightknots l have read that information quiet a few times and articles like that made it hard for me to make up my mind so l will test it out then see whether l keep them or not .

     

    cheers Geoff.

     

     

  18. Hi Geoff, I'm not going to get the thrust from the jab motor that you need for stol flying so I'm thinking that I will not get the benefit from putting the slats on. My plane came with a very heavy EA81 so I pulled it out. Wanted to put a Rotax 582 in but not much change from 10k so got hold of a jab motor with 2 hours on it veary cheap. Wanted to be as light as I can. Do you know of the histroy of your plane? I was talking to the original owner of my 701 and he said he went to gippsland for a ride in a 701 and the pilot clipped a wire coming in to land, scared the **** out of him! Cheers.

    Hi Phil that is the plane l bought the owner was playing around with vertex generators when that happened this aircraft has had a lot of hard landings that's why l have stripped it down completely l am just finishing off a new fire wall it was bent and split replaced the main spring, wheels and nose leg l am putting in wing tanks l got rid of the 40lt fuel tank sitting over my lap l am not keen with fuel in the cabin.

    l am changing the wing struts with airfoil type of a savannah this 701 used to drop the right wing severely in the stall ,this 701 has done 351hrs it is the original 701 that was first designed for the 503 or 532 it has a 912ul in it now.

     

    cheers Geoff.

     

    ps are you far from gippsland .
