Hi Skybluerob

It looks like we have the same problem, is there any chance that you can get your motor to Baileyn to have a look at. Hopefully I can then apply the same fix to my motor. I'm in New Zealand.

cheers,

Jaco

sorry, Morgy

Hi

I can not comment on the Zenith set up, but every Bailey V5 owner i know and have sold too have no issue restarting while in the air. Even the one's with Baboon arms

Firstly i would suggest going back to your dealer and get a hang check just to make sure the geometry is correct if you can not find the Pull cord.

Also You say it takes 5-6 pulls to restart??? What carb do you have PWK or the New CVK? The PWK can be a bit of a pig.

I regularly switch of while thermaling and ridge soaring and have not had an issue with the new CVK. My PWK carb V5 Had two starting procedures depending on how long i was turn off for. If i was thermalling at height and for a long time 45m 1h30m and the motor would get very cold and i would have to use the primer bulb switch on the choke. I also had to crack the throttle open a tad then pull start... Basically the same as you would on your back while warming it up. The other way was to just crack the throttle open a little no choke and pull.

The CVK is similar while cold on the ground But with no choke.

Prime until the bulb goes hard. Very cold conditions 5-6 pumps on the throttle then pull the pull start cord. It may fire once then stop. This is normal try again. As there is no choke it will need little pumps on the throttle to maintain rev's and to stop it from cutting out... Normal operating temps... Primer bulb until it goes solid. A couple of pumps on the throttle crack the throttle a tad 1/4 throttle then pull start. Again you may need to gentle pump on the throttle until it has warmed slightly... Again this is because there is no choke and uses a primer pump on the side of the carb.

The pull start should be almost touching the back of your head while seated in the machine. On a Bailey V5.

Basically go back to your dealer to fit you into the harness correctly and to show you the starting. Get the carb upgrade if you do have the PWK.

hope this helps

Remember me? Rob?I met you on the service station to take the V5.

I bought the V5 off you in August 2012 and had a problem starting the thing from new. Remember me phoning and texting you with the problem?

You say you don't know of any people you've sold these to that have had problems!!!

Mine has been terrible for starting...easy start my arse!!...and it isn't due to bad technique as you suggested!!

I need it sorting....

Hi

What trim settings do you use when doing spirals or wingovers on a revo2? I started doing shallow wingovers and they feel more stable when on 0 trim than on the 2/3 takeoff trim that Paramania suggests.

Does the Revo2 have any strange characteristics when doing a spiral? Is it easy to exit a spiral? Will it exit by itself without input?

Here I'm taking of from the town's 100m * 100m golf course

On my way to the site I noticed a 20Knt NE wind , but when I got to the site there was a light Southerly sea breeze. This made me very nervous but it was a 2 hour drive so I took of anyway After passing the town I also noticed white horses about 1km offshore, so it looks like the NE were blocked by the hills and then dumped 1k out to sea

I stayed low and it was smooth air most of the way.

Hi

sorry to bring this post back up again

I now have the problem with the pulley system mostly sorted out. (It is not as good as the Bailey frame , but good enough)

I have no problems anymore with starting the engine from cold, with the engine on my back.

I still sometimes have a problem when starting it once the engine is warm. What happens is, when I pull it feels like the engine fires and then rip the pull chord back, and then stops, this will then keep on happening and I then have to start it on the ground. Has someone experieced this problem? or know what might be the cause?

Other than this problem, I'm very happy with the Bailey engine and would buy one again.

Hi davidreckitt

I now have exactly the same problem with a revo2 and parajet zenith, it banks to the left on landing. I kill my engine when I flare.

Were you able to solve the problem? I know they said you should use weightshift , but it is not that easy when hanging from the leg straps.

Hi

No, I didn't know it was a private air field . But there was no other traffic and no one tried to stop me

Was it a paragliding accident?

Hi

This is from my flight, yesterday. Take-off from Whitireia park, Titahi Bay, NZ

Hi

I went flying today and the engine started from cold on the third pull.

Thanks to everyone on this Forum for all the help and suggestions.

btw. Parajet responded and told me that they are designing a new pulley which should make things even easier.

The engine now have 7 hours on it.

Here is a new video I made flying at Raglan on the west coast of the North Island: http://youtu.be/UYDufihUDUw

I think my problems are over

Yesterday I got it to start while it was on my back.

I started it on the ground and noticed it started very easy on the second pull, I then went flying for an hour, when I landed I killed the engine and tried to start it again, it started on the 6th pull.

It now pulls much easier and I notice the propeller keeps on turning over for one or 2 revolutions after I stopped pulling, previously it stopped as soon as I stopped pulling.

There was 2 differences from previous attemts:

1. Previously I kept the oil level at +- 85% full. After reading Paul Bailey's email, I filled it to 100% full.

2. On this flight I realy gave the engine a work out for the first time, climbing for minutes at a time with the throttle at 80 - 90 %. Previously I only used 50% or less throttle, except for take-off.

Hi

I'm still waiting on Parajet to reply now that the engine has been ruled out as the cause of the problem.

In the mean while I start the engine on the ground, then lift it onto a cooler bin and then slip into the harness, but it is just a matter of time before I get a finger chopped off

I made this video on Saturday, it is probably the first time anyone has flown this site: [youtubevideo]

I'm happy with Bailey's reply.

Hi

reply from Bailey:

"When the starter is pulled the engine appears not to turn over as easily as it should, this could be a number of things, firstly (and rather obvious) has the engine got the correct grade of oil in, it should be 10W-40 or 10w-60 fully synthetic and filled up to the top of the oil window.

Secondly there is a 'whirring' noise from the starter pulley as the rope is pulled, this suggests friction, I am not fully familiar with the Parajet pulley arrangement but if this is a 'bushed' pulley rather than a ball raced one it may need some lubrication.

Thirdly, as the rope is pulled, for the first 6 inches or so it is clear of the harness shoulder pad, after that the rope touches the pad at a progressively increasing angle as the pull reaches its full travel, this will cause a great deal of friction. I would suggest adjusting the harness straps so the machine is much higher on your back to prevent/reduce this.

One more thing I noticed is that when the engine is pulled and does not start the prop stops rather abruptly, this could be drive belt tension slightly loose (see manual for correct tension adjustment DO NOT OVERTIGHTEN) which would make starting slightly harder due to the reduced inertia effect of the prop as the belt slips slightly. It is possible and quite easy to start the V5 on your back without the prop on though i.e. zero prop inertia.

My conclusion is that I do not think there is a fault with the engine but would recommend reducing the friction affecting the rope during its travel. 1)Pulley, lubrication??? 2)Stop rope fouling harness pad during travel, (adjust harness so machine is higher)."

The spars on the Zenith clips onto the engine mount plates with a spring clip, it won't be able to support a pulley. They will have to build a 20-30cm extention that screws onto the plate where the pulley is now mounted and then the pulley will have to go on top of that.

Parajet told me that they have other customers with Zeniths's and Bailey motors and that they don't have a problem with starting. I'm still not convinced that the main problem is with the pulley or technique.

I would say on my engine it gets about 30% harder to pull once the engine is warm. This is just enough to force me to use to hands to start, because I then have to use 2 hand, I can't pull the cord as far out as with one hand, or control the throttle as well as with one hand, this justs adds to the problem

I mean it is much harder to pull once the engine is warm.

The first start (cold) I could pull it over with one hand. After it ran for 3 minutes, I had to use 2 hands.

cheers,

Jaco

thank you Barry

Maybe Parajet can build me an extention that will lift the pulley by 20/30cm.

But that still does not explain why it got so hard to pull after the engine ran for 3 minutes.

cheers,

Jaco

Hi Al

It is as high as it can go, I can't tighten the shoulder straps any more. Because it is so hard to pull, the only way I can generate enough power is to pull it down.

thanks,

Jaco

here it is: https://www.dropbox.com/sh/7ypg27lenuhn3jz/y5uC3cPLBl

I have not heard back from Bailey or Parajet.

cheers,

Jaco

Hi Morgy

Yes, I agree, it is in a uncomfortable position, if it can be raised 20cm it will make a big difference,it might just be a case of a new engine that is hard to start and pulley that is in the wrong position.

After how many hours did your engine get easier to start?

Bailey and Parajet have asked me to send them a video of me trying to start the engine, if they don't see anything obviously wrong I'll return it to the dealer and they will sort out the problem with Bailey's /Parajet help.

I really hope it is something I'm doing wrong, or something easy to fix, otherswise I won't be flying for months.

Hi Mark

There is no point where the compression stops when pulling the cord. It goes from very hard to pull, the first 20cm to hard to pull. There is no point where it gets easy to pull.

When pulling it , it feels like you are pulling a rope that is wrapped around a heavy wheel with a heavy weight on on side of the wheel. The first 20cm is very hard to get the wheel moving then it get slightly easier when the wheel starts moving, but you still have to pull extra hard when the weight is at the bottom of the wheel, to keep the wheel moving. .

cheers,

Jaco

Nope, still no luck, I now believe the main problem is with the engine, the cord moves freely over the pulley even when pulled at an angle

This is what I noticed yesterday:

1)First attempt of the day with the engine cold and primed.

With the engine on my back I can pull the cord with one hand, but can't pull hard or fast enough to get it started.With the engine still on my back I got a bystander to start it and it started on the first pull.

2)Second attemt of the day, the engine has been running for 5 minutes.

Now I can't pull the cord with one hand, I have to use 2 hands, it is very hard to pull. I get the same bystander to start it, he is struggling to pull it, he has to pull so hard that I have to brace myself before he pulls.It started after 5 pulls.

3)Third attempt of the day, after 45 minutes of flying.

Have to use 2 hands to pull ,give up, tried starting it on the ground, give up after 10 pulls.

(I have send this to Bailey and Parajet)

I think I found the problem

I watched myself in a mirror when I pulled the chord and the chord moves over the throttle cable that mounts next to the pulley when it is pulled at an angle to the right. This will cause a lot of friction. I have removed the throttle cable mount and move it lower on the frame and out of the way. I'll try staring it with this new configuration tomorrow.

I should have listened to you Morgy
