The Cyprus A10 THUNDERBOLT

Yes i know he was , he's said it before so i thought i would make everything clear for him
Owen i was involved in a trafic accident, not my fault in any way and they held me in there for 8 months

That IS bad.

if you dont have a go you will never do it.

Dead easy to make BB ... Here's one end of one of mine. Instead of using wooden dowel, use some heavy piano wire & you've got an automatic tensioner.
I used a wooded brush handle for the main body of the bow on this one .... I've also made them from plastic pipe from any DIY shop.
The most important thing is to use the correct wire though .... you need something with a bit of electrical resistance .... NICHROME wire is probably the best. It's the sort of thing they use on the old style electric fire elements & is very cheap.
It's no good just using something like a guitar string .... you need to pass a lot of current through it to generate any heat ..... & the connecting cable gets hot.
The bow in this picture will cut widths up to about 40 inches & will run on 22 - 24V & only pulls about 1 - 2 Amps.
I use power supplies, lead acid batteries .... or even get an hours continuous running on two 3S 1800mAh lipo's in series.
I even run it through a footswitch so I don't keep burning things when I put it down.

Thanks Pol that looks the biz, all i need now is to find some foam over here there must be some somewhere, but god knows where,
Yes Owen it was a lot worse than it sounds

I was not happy with the standard of woodwork on the nose of the A10 so i pulled it of this morning and did it again
Starting to take it off


And the new, a lot better

Then i changed my mind about lining the inside of the nacelle,think it's best left with space around the turbine
I added a former to the front of the nacelle for the inlet air hole
Then i put the outer ply skin on


Got some more of Pol's foam and started the front moulding round the intake, still working on the final shape inside the moulding








That is the access hatch




Make it up as we go

looks complicated to me.
best of luck with the build BB it is looking great.

I think that foam will only stand about 130^oC ..... you could skin that orange foam with fibre glass just in case.

That is the cold end Phil, it will be just fine.

I was going to fibre glass it anyway but as Owen said it's the cold end, the hot end i think will be balsa also fibre glassed, the exhaust gasses are around 800deg i think , is that right Owen so it will need a exhaust pipe making.

My turbines have an exhaust temperature of between 500 and 600deg and it should be sufficient just to make a liner for the nacelle with just an empty can, (beans or similar)

I was wondering about that, as on the Sprint the outlet area i did it with a cornflake packet and some sticky tape similar to the stuff they use for flashing roofs
and iv never had a problem with it,
Only thing is for a scale apearance it should have one, but mine is a stand off scale until it has flown, and my stay that way if it looks ok

Whats the biggest ally drinks can or ally can thats available, anyone know, ERIC
