I can see why you moved to France. A mate of mine had half a mind to move to a job in the Dodogne, but turned out that in having half a mind he was hopelessly overqualified.

Re spelling - Where is the Dodogne?

As for running, the engine throttle open to clear it, until you forget the ignition switch and it takes your fingers off,, :-X

OK I have seen them on Ali Express, do they work?

Re losing fingers -

I start large glow motors by:

Fully open throttle, finger over silencer outlet and turn the engine over a few times to get fuel to the engine using silencer pressure.

Close throttle and flick the prop to feel the fuel loosening up the engine till it "feels right"

Put on the glow clip, apply starter and away they go.

Turning on the ignition would be the equivalent of putting on the glow clip so that sounds ok to me.

Quote from: itsme on July 23, 2020, 08:14:30 amI have an OS40cc FS petrol. Loads of power, bit noisier than I expected, starting was my problem, fitted inverted it kept chucking the prop loose. Now I open throttle wide with no ignition on, use my geared starter to run it a couple of seconds, then low idle and ign on and it starts easy. Use a nice heavy glas filled prop, when new they need that weight to keep a good idle.

Itsme, What starter are you using please. Re prop, it had an 18 x 8 wood prop  which seems small???
I will be fitting a GF filled prop but do I stick with 18 x 8 or can it handle say 20 x 10 like my MVVS 40cc (on a tuned pipe)

Quote from: FlyinBrian on July 22, 2020, 20:12:59 pmI reserve judgement on glow v petrol. I prefer the sound of a decent four stroke glow engine to all petrol engines running without a canister or other decent exhaust.

OTOH I have recently obtained a Boeing Stearman Bipe of around 6 foot span fitted with an OS 40cc petrol FS, this uses what looks like a large glow motor exhaust and in a video sounds great - will be giving it a test in the garden soon. Along with the ASP 120 I have refurbed, of course I need to find the so..ing wood-ruff key for the prop driver which crept off when I was not looking.

Slope / Re: Slope Soaring in Lincs??? ...
Last post by itsme - July 23, 2020, 08:08:03 am
There is a slope near RAF Scampton, dont think there will be anything in Humberside. Further north there are loads. Not much shown on http://www.slopehunter.co.uk/ but they are there. In an Easterly, coast slopes are good. Hole of Horcum is the well known one. In the days when I got free petrol (!) I used to travel many miles, Derbyshire, Long Mynd, St Agnes etc.

Methanol at 35€ le 5 litres over here is over taxed and out priced. :o

Big 4 Strokes are too expensive. :-\

Petrol engines are cheap and cheerful, cost nothing to run but make
an awful noise without a canister, that's the way I have gone. :study:

Electriackry is RUBBISH, a wheeee, sort of annoying noise, not eco friendly to make the battery's that are overpriced and  $%& don't last,  minerals that use slave labour to mine, not recyclable, :-X  and worse thing is short flights, for some a sure way to break their toys with a death defying landing every 5 minutes,,  :nananana:
While my crash landings are every 15 minutes  33% less chance of breaking my toys. :uk:

awaiting P** reply  :co

Quote from: itsme on July 22, 2020, 14:36:26 pmI totally agree that veggie is not the way to go with big models. However, with a third of lithium going in to batteries, there is still around 40 million tons of the stuff available. Super Tigre 3000s were good engines, but outclassed by Moki 180s, and both now pointless with the excellent petrol engines available.
I agree that petrol is probably the way forward (I have some) but I bought this model with the almost new ST2000 (25T) in it and thought it would be a shame not to use it.  So far, except for the needle issue it is looking good.  And there are some on eBay as predicted so that should soon be solved.
