RottenRow Posted September 10 Share Posted September 10 You can’t (legally) buy or keep neat nitromethane nowadays. Or anything containing above I think 30%. Just in case you make a bomb… Brian. Quote Link to comment Share on other sites More sharing options...
Andy Stephenson Posted September 10 Share Posted September 10 The government were thinking of cutting down the legal level, if I remember correctly, to 17% there was a response document posted some time ago about this so I sent in my objection. 1 Quote Link to comment Share on other sites More sharing options...

I have always mixed my own fuel as I like to know exactly what's in it and it's actual cost works out maybe 50% of the ready mixed stuff that does not even list the ingredients although the blue offering is reputed to contain cruelpower oil. 😱 Thankfully, here in Australia, 20L drums of Shell Racing 'A' methanol, most decent oils (Klotz, Castrol etc) and nitromethane are still readily available nitromethane 2.5L. Competition racing glow ignition engines are pretty picky about their diet and even a Cox Tee-Dee likes at least 25% nitromethane to get it really going for some events. * Chris * Quote Link to comment Share on other sites More sharing options...

More correctly, you can’t buy or keep nitromethane or mixtures containing 30% or more by weight without an Explosives Precursors and Poisons licence. Provided you haven’t been a naughty boy in the past, this is just a matter of filling in a form and sending £39.50 to the relevant department.

Cuban8 Posted September 10 Share Posted September 10 (edited) Why on earth would you bother mixing your own and particularly for sport flying? Edited September 10 by Cuban8 1 1 Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted September 10 Share Posted September 10 I never get why folk question how others want to do things, why on earth should it bother me/you, if someone brews their own fuel ? Mind you a fella at our club builds models instead of buying ARTFs, how weird is that ? 🤔 11 2 Quote Link to comment Share on other sites More sharing options...
Cuban8 Posted September 11 Share Posted September 11 (edited) Perhaps it's simply a discussion point, after all, we are contributing to a forum. Ideas and views are exchanged and not unnaturally, opinions and preferences will differ. Providing things are kept polite and respectful of others' ways of going about things then I don't see any problem. On the specific case of diy fuel, it's something that only a tiny minority of flyers do these days so it's unusual and worthy of comment just from that standpoint alone. The trouble with on-line discussions is that they lack the normal face-to-face conversational interaction between contributors just chewing the fat over the field or down the pub. Not saying that those chats don't always follow an ideal course. However, a wry friendly smile or raised eyebrow adds so much to nuance a 'real' conversation and that effect is missing from a line of quickly typed words which can be all too easily misinterpreted - even with 😀 etc. I guess we don't always get it spot on.

Paul De Tourtoulon Posted September 11 Share Posted September 11 One of the clubs that I was in the 1980's, had a garage owner so Methanol and oil was trade price so it was a no-brainer. In the 1990's, I got the same stuff for my model shop only 40 kilometers away, so still worth it. But today, 220klm round trip 7€ for the autoroute and the price of methanol, oil, and you can't but nitro over the counter anymore, not forgetting car diesel and 3+ hours of driving, it just isn't worth it where do you get it from Edgeflyer ?

Not since the 80’s with my late Father. Both glow and diesel. And an excuse for a sniff! Shudder to think what the ‘do-gooders era’ take would be on having tins of Amyl nitrate around the garage these days! 😀 Would not think it cheaper now although ours was more of necessity and good access to source materials.

Martin McIntosh Posted September 13 Share Posted September 13 In the 70`s many of us mixed our own fuel because it worked out very much cheaper and was generally 3:1 castor/methanol would you believe? Pylon race motors were required to run on this as did my OPS 60s which were ABC high compression. Nowadays of course we use synthetic oil at a much lower percentage but the ingredients are not so readily available, especially nitro. I could buy the stuff at a local oil dealer.

Paul De Tourtoulon Posted September 13 Share Posted September 13 We still use 20% castor mix on pylon racing, you have no choice, it's in the French regimentation, and supplied by them in the competitions. Quote Link to comment Share on other sites More sharing options...
