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 ?

Dare I comment... I use those cool looking ( coolness or fashion are not part of my life ) reflective mirror like glasses when it's bright. From time to time I fly with the sun low in the sky, and it's directly into wind. Like with a car, a sun blind or sun visor is needed, that box thing I hold in my hands, flying above it or below it when it's used to "block" direct sunlight.

Hi diamond geezer, Parcel arrived at noon, well packed and the pisty even used the door knocker ! Seems the rarebird has been started with fuz longerons joined, then broken to fit the box ! No matter, not a problem. Briefly check contents, all seems to be there. Thank you so much, very much appreciated. I am giving you a sales rating of 100percent, from a happy bunny. Thanks again, from rich.

I believe paw can supply castor oil. Would have to check on model technics fuels... During a recent telephone conversation with Weston's about zip diesel fuels and glow fuels, I was told that they can mix "any" customer specific fuels to order. I was told some time ago now that Weston's fuels did not contain any caster, but it seems that is not correct these days. Perhaps worth having a chat with the young sounding chap who mixes the fuels at Weston's ......

Brilliant, thank you so much, very much appreciated, thanks, rich👍

Any news yet dg ? A white envelope or RM red card ? Over...

Thanks leccy.

Vast Majority of instructions on download ( translate German to English function comes up on screen ) are bilingual, German and English. Some stuff on page one needs some translation, Google or the lad will help me with that. Great that the download is A4 friendly, only £6.20p cost to print out in library, black and white. Not fully studied yet so esc info may be hidden in download somewhere, such as type, amps etc.. The site and mag looks very interesting, again translated into English... Other stuff shown not just aero subjects, a little bit like rcme used to be..... Enjoy

The very inexpensive foam chuck gliders ( £2.99 is the cheapest I have seen, last year/summer season ) seem to sell quite well. Not a lot of instructions/graphic on the labels...... The much cheaper ( 50p ) coloured profile chuck gliders are quite popular too. Maybe parents should route out indoor flying event locally and take the kids along. Dad took us kids ( all the boys at any rate ) to a slope soaring event in churchstoke was it ( long mynd ) , some 60 miles plus from home. All us boys joined the ATC and had flying experience. My elder brother and myself are aeromodellers, my younger bro, hang gliders...my lad, ppl but could not afford to keep up experience, way too rich for our meagre budget at the time. Such is life... Looking forward to kits arrival... Thanks dg.

As if you didn't know before, this is one reason why slope soaring is so fantastic !

Diamond geezer, look out for largish white envelope, first class post should be with you tomorrow. Please confirm its safe arrival, and dispatch of your parcel when posted. Thanks again dg......rich.

Do you think the posty can see the road signs ? Like me, they cannot see the large sign in the window right next to the front door that says " Deliveries, please use the DOOR KNOCKER provided". The posty says he can read.

Cool, so £32 in total ? Saw pm with address, trying to see address again...

Yeah, suppose so....

Thanks leccy, eye test booked, 🤓👍, much appreciated.
