simple solution every time.... Don't bother balancing With the size of that repair the weight difference will be bugger all, just file it to shape when totally hard. and wet and dry till smooth. If you want to check perfection. use the kitchen digital scales and weigh each prop, if within 3 grams of each other your on a winner. Don't bother with the next bit . Check the balance of the heaviest prop by balancing across a thick blade (edge of a file held in a vice is good) and mark with tip-ex the center of balance on each edge. now transfer the marks to the other 2 blades. They should balance at the same point. If not a generous application of spray lacquer to either tip/ root or full length will bring the weights into line. Simples Colin B

blatantly ripped from another site. The BHPA Club Pilot (Power) qualification once gained allows pilots to fly without instructor supervision, providing that he/she keeps within two miles of the take-off point. The BHPA Paramotoring qualifications are the only ratings recognised by a British association. One big advantage is the Third Party Liability cover to £2,000,000. More questions. How valid is the insurance should you drift further than 2 miles? for instance my village is a turn point for a BHPA school, at least 2.5 miles away How many flights within these two miles are you required to undertake, before you can upgrade to "pilot" and take advantage of the much coveted insurance cover? Colin B (Not the ugly one)

Just out of curiosity Pete, What exactly were you searching for, when you came across this video delight? Tis good though ain't it

Pj508/200J EL made by Contitech (12 Rib) Same as Parajet compact / cors-air m25y Available from Hypermoto Gloucester GL2 4RF £16 plus postage if i remember correctly. Tel Chris : 01452 729272 A very helpful chap.

As the fault is affected by engine revs / vibration, I would start by looking at the earth connection on the coil Colin B PS. you've got more mates than Dave

Or put someone else's number on your wing and hoon around their manor in the hope of getting them a visit from The Man. As for security. Smart water or Alpha dot is effective, cheep and fully backed up by the feds. For a social recognition register IE; motor, wing type, colour, phone number etc I believe there is already such a thing (its just not very up to date or mandatory) cant remember the site but it was mentioned in the last long winded bun fight Colin B Oh and Matt.......... You beat me to it! But lets All put francis`s number on All our wings.

Here you go Francis... Posted in all relevance to the fact that one man (although slightly misguided) may never walk again!. Well done sir! It wont be the actions of the pilot involved. Minor airspace violations, Or parts failing on Experimental aircraft, that will get the sport regulated beyond the reach of mere mortals. It will be YOU. If you care so little for the sport, don't play it! ................................... The people of Walkden (and elsewhere) may be surprised to learn that no pilot training or licensing is required to use these machines and that no regulation exists to regulate instructors. Which means that anyone can legally buy one off ebay this afternoon and legally fly over you and your house this evening and anyone could wake up tomorrow and decide they are a "paramotor instructor" and start selling them and charging people for showing them how to drive one. There is no law requiring the person driving it to have any insurance. Neither are these craft required to have any airworthiness certificate and the construction of them is not regulated either. Many are designed and built from bits of junk cobbled together. Even the wings do not have to have any form of certification whatsoever. You might also be surprised that the government have no plans to control this activity and we can all trust to luck that no children were playing by that wall yesterday or the site of the next crash. 90% of people who are interested in this form of flight are males in their forties and fifties.

You don't want to stop at 1600m that's 4m short of a mile high! 5265 ft is what your aiming for Yes, its perfectly possible to fly that high, and higher. And legal so long as you don't climb into any restricted airspace. Our local area has a 6500ft ceiling before we are in class A Wrap up warm. Expect your motor to be a little sluggish at altitude. Don't fly in the clouds, that's where mountains hide. And take a Camera

Before you remove the flywheel I assume your using the correct octane fuel, And have fitted a NEW properly gaped plug? Just a thought, Both can give the symptoms that appear to be the timing Colin B

Halfway between Swindon and Oxford on the A420

Baz. You can borrow mine for a while if desperate. Im having a bit of time on the ground due to the new sprog You will have to pick it up though, Give me a shout 07789 770741 Colin B

A slightly different approach, due to a dislocating shoulder and having no strength with my arms behind me. I hold the A`s up in the flying position, Find the centre. Apply 1/4 power, walk forward holding my arms in position. As the wing comes up It slows me down until the its above me. When I start moving again apply full power and away we go. 99% success rate, and no effort required Terms and conditions apply. Colin B

As for the second question. Check the weights are still valid with a set of digital scales. A set of blades with a range of 5 grams heaviest to lightest is acceptable, Exact would be perfect but unlikely. If the weights are further out you will feel vibration. More than 12g out and you will feel your teeth falling out, with the added bonus of metal fatigue and bits falling off your motor. (If the blades are near the same weight but still vibrate like a mental washing machine, then they are out of trim. And require more work than can be easily explained) Colin B

Not if you use 2 shims per blade on either side, with the fat ends in opposite directions Assuming of course that all shims are the same thickness. Colin B

I have a pop off gauge if your local`ish. And the plug gap is very significant Colin B

Guilty your honour. I have at times committed aviation from South Cerney (RLC Unit) And another field that is only talked about in hushed tones by the privileged. Colin B

I was going to write an essay on this, but I wont First check the "Donk" is lying at the bottom of the tank covered in fuel. There are no kinks or restrictive cable ties on the fuel line and the filter is clean. Then check the breather pipe for the tank is clear. A dead giveaway for a blocked breather is opening the filler cap straight After the motor has stalled and hearing the rush of air entering the tank. (a vacuum has formed, starving the carb of fuel). By adding fuel you will have already released the vacuum and the motor runs fine for a while. If all is OK. I would suggest the problem lies within the carburetor. A weak/damaged diaphragm will rely on gravity feeding fuel up to the carb (IE more fuel in the tank). probably Colin B

Its Witchcraft I tell ye.

I take it they don't fly the Jindivig from there anymore? I'm not a spotter. went there as a kid many years ago Nice area. Colin B

PS - there is also a longstanding problem with the Simonini pulleys on the 3.1:1 ratio that it may be worth checking. Apparently the machined grooves do not match the poly-v belt correctly, leading to premature belt failure. The attached pics show my belt after just 10 hours (shown inside out for clarity). [attachment=1]Kobra Evo 006.jpg[/attachment] [attachment=0]Kobra Evo 005.jpg[/attachment] Kobra have already sent me some new belts (upgraded quality) and have remachined their own pulleys to permanently cure the problem, with a set on their way to me now. It may be worth keeping a close eye on your belt if you are running this reduction ratio ..... Them there Belts look very familiar. Had the same problem with my cors-air. But not directly caused by the Grooves in the pulleys. More by the way the two pulleys were fractionally out of alignment after I had changed the reduction ratio It appears I had pushed the small pulley further onto the crank than factory intended. After two quickly destroyed belts. I removed the thin shim between the eccentric cam and the crank case (there for such adjustment I assume) and all was back in line. Moral of the story. Check the alignment before fitting £60 worth of belts Added bonus. I`ve found a supplier for Cors-air / Parajet belts at only £16 each Colin B

Was an awesome day for sure. Great to see so many faces, and some truly spirited flying. Bit like a mini fly in Colin B (the one that got out of bed )

I`ll take yer money Simon Says he`s had 15 hours on it already. Colin

Will be there for sure....

It would be rude not to attend. Ill be there Colin 2
