Hi everyone out there in the US!

Are we having some bad weather over here right now, (still it gives me chance to perfect my limited modelling skills).

I can also get the engines sorted as well. - Can anybody tell me the correct length of the 4 UNC headbolts (6 of) for a Fox 35X? I could probably find this out in a few minutes by taking one out of an engine, but as I don't want to disturb the head after a recent rebuild (29X) I'm not bothering. (I think they're 1/4") I also need a prop nut too.
Incidently I've stumbled on an foolproof method for making the 23% mix required for these engines;

I use model technics Contest 10 (10% nitro with 18% EDL oil). To make 1litre I simply make the fuel up in two parts, adding 50ml castor oil first off to make the total oil content approx 23%.

This works well with a fox no8 plug, and I use these in all my fox strokers!

......... I'm investigating mixing different nitro contents next. O:-)

PS The Scaremonger FA1 46" Ironmonger is well on the way to being finished - just hope that tank lasts this time!!!

Cheers BigIron,

I'll order some from Westfield Fasteners, also am I right in thinking that the 'X' series Fox motors are the same aluminium piston/steel liner design akin to the 35 Stunt? (I'm trying to get an ideal oil content for running them. - I understand the combat  motors will be fine on a leaner fuel mix mainly due to the needle roller bearing crankshaft).

Nearly right then! I've actually found a place not all that far from me which sells bottles of pure nitromethane and methanol. - As I've got more than enough castor oil at the moment, it would probably be an idea to have a go at making my own glowfuel. (Only problem is they don't send it by post, for obvious reasons!!!).

I'll see how I get on with my 10% once the planes in the air. - I might even by some 25% nitro and mix it 50/50 with what I've got. (Only have one branny engine out of the three I've got, and don't really want to have to use it as a donor when a crank lets go!)


Cheers,


Tim

Thanks Bigiron!  Seems to be the Achilles heel on those engines!

 I believe the metallurgy wasn't great for some reason. I suppose they were building them to a make a profit and probably didn't realise they'd still be sought after fifty years later! (Pity they never used machined crankcases with the earlier ones either. - I love these engines,
like a 35 Stunt on steroids.)
