No what?

No, it doesn't look like an ugly ЯК.

Flying wires. I have ran out of the wire supplied with the model. It is more heavy duty than usual stuff. Measuring it comes out at 0.8mm or 0.032 ins (32 thou) No idea what it is wire gauge. I think it is stainless and possibly coated.

Can someone point me in the direction for this wire please.

Your wire is almost 20SWG (.036), but that doesn't allow for the nylon coating. I'd try a fishing tackle shop that sells "Trace Wire". As a bonus, its a lot cheaper than model shop's "Pull-Pull" wire.

Phil I've got some green coated trace wire 23.5 thou green 20 kg as Brian says fishing tackle shop.
You are welcome to some of this if any good .

Thanks John. I need nice shiny steel wire. Got some from a fishing tackle shop as suggested. Took a piece with me because they only talk about weight and breaking strain.

Managed with a struggle to get the Pitts down the stairs without any damage to decor and plane. :whistle: Once outside I could trial fit wings and struts. Not too bad, a little sanding of lower wing slots. Fuelled her up and flicked and flicked, nothing. Plug is good. The engine has been in a Tesco carrier bag for around three years in a dark corner of the garage. I probably expected some issue. One thing to try if it's the flappers stuck - squirt neat fuel down the carb. A few more flicks and it fired. Choke back on, a few flicks and fired. Off choke and four flicks and it's running. Let it warm up and get it oiled up. throttle response is good (I had already set a likely curve). Runs sweet, idles down well too. :whistle: That'll be a relief for Dave B who I bought it from.:lol:

With that sorted I have gone over all flying wire anchor bolts with Loctite. My next task is to baffle the Cowl. The cylinder head sits behind the bottom of the cowl so need to force oncoming air past the engine fins. I will blank the left side as seen from front and also across the top. I have some white board stuff, about 6mm thick and smooth finish on both sides. Very light, inner core looks like compressed epo.

Can I use this? and if so how what glue to fix it with in cowl?

Thanks.

Phil

I have used what sounds like the same stuff to baffle my 104 Extra, white gloss card with foam infill. Has worked perfectly, heat has not been an issue at all.

I used Gorilla glue to fix it, which has held up very well.

I thought it might be the same stuff you used. It came out of a box a long time ago and I just kept it in the odds n sods drawer. I think it might have been the PC21 possibly. I will have a go with it then. Maybe paint some cylinders on it......

I assume you cut it to shape and use Gorilla where it touches the GRP cowl?
