Bye laws ? Local council offices, enterwrb, public library ? Is it national trust site ? Maybe RC gliders in winter, manned ( or womanned) flight in summer... Bmfa would have details I would of thought, or paragliders national body/clubs ? Hate to say this but para porkies?? I don't think for one minute it's pars porkies, buy you never know......very naughty if it is....

No problem dg...👍

Your wife has permission to play in your workshop ? A truelly liberated woman, but what happens when a car tyre is flat or gutters need cleaning or two tonnes of wood needs sawing by hand etc. ? 🤓

if you have a suitable slope that is close, the closer the better, visit and see what goes on. You may be amazed. Look at pssa pictures on here, great orme etc.......

It's space, my model room way too small for these sized wings... Now better weather is here and deck nearly cleared, old shed to empty, new shed to erect and fill, then I will have my 10 X 8 shed free enough of motorcycles so I can use it for what it was purchased for, model room/electronics. Still got to get a diesel heater for the coming winter. Anyone want a motorcycle project, tax and mot exempt 250 honda nightmares, both runners, sdm used on road...classics apparently, bit of a cult following, god knows why, superslugs but good fun on back roads... Pm me if interested...

Thanks guys, just awaiting a quote, I will be sitting down ...

Cheers rr, I knew I had seen it somewhere, didn't think about bmfa news. Pity it's not in paper form these days, internet is really crap here, ee, phuee !

Thanks guys, very much appreciated.

Anyone making veneered foam wings to order, mail order, these days ? I could have sworn there was a small box advert for same in the back of rcme ? Been looking through the mags as far back as 2019. I'm blown if I can find it. Would anyone know please. Thanks in advance... rich

I haven't read the above but was the nitro content dropped to 15 percent, from memory. Yes, water and ethanol like each other, a good way to remove the ethanol from modern petrol, but requires a "dedicated step up etc , which is no big deal if you have the space. Living on the 27th floor, forget it ! Screwfix and other similar companies sell stuff in small bottles for quite a few pounds, which seems to work, so far at any rate. Some confusion may be happening in this thread between petrol for vehicles and machines such as outboard motors etc., And petrol powered model aircraft engines, perhaps ?

When I enquired in boots the chemist, I was thought of as a terrorist. When I enquired in the other chemists shop in town, and explaining why I wanted these liquids, the prices where just stupidly expensive. Internet, eBay, us cheaper but delivery is the problem. I probably will go with Weston's when my present stock runs out, defo by autumn. Saving hard for a petrol engine about a 40 size. The laser jar has been relabeled.....

You mean assembling the porche engines rather than machining ? Do you live on the llyn ? Back to the diesel, when compression screw backed off a bit, do you hear the sometimes quite loud crack of the contra piston returning, and a small amount of smoke ? May I ask about the atom minor, crankcase machined from solid, or a casting ?

As Jon says.... If you move prop from bdc, over compression, and stop at say 15 degrees atdc, reverse direction to 15 degrees btdc, and repeat, how many "cycles" does it take for compression to reduce to zero ? Atom minor, nice...will you be starting a new thread for that ? Still need to read this thread from the very begining to read of the "engineering" involved. I only have a basic machine Mart lathe ( new, small one ) with imperial and metric lead screw etc. and 4 jaw chuck, no milling machine, yet.... The old atlas lathe is not "accurate enough" for model IC engine but ok for steam engine and general none high precision jobbing lathe, it's well worn and used quite a bit, being ok if you "work with it"....

John deer should read John Deere.

Hi hill climber, A good source of ether is John Deer easy start', about 70 percent from memory. Have you tried warming the engine prior to starting ? Does the warming reduce compression....I presume you are happy the engine is "pumping", and has good crank case "depression"... I am sure you can "knock up" a suitable "pressure indicator, for both negative and positive pressures..... On priming, via exhaust port only, just a single drop of fuel, a small drop at that....printer ink kits have smallish syringes, if you ask nicely at the chemists ( and tell them what you want it for ) they will sell you some small syringes, just be really really carefull with the needles !! As has been said, take a break from it, come back refreshed... What fuel are you trying it on by the way ?
