Black Widow? Empty Black Widow?

Post  Ivanhoe Tue Jan 10, 2012 2:23 am

I've just won this on EBay for $10, looks a little rough, but at that price I'm not worried, I'm wondering if it's a Black Widow? It wasn't listed as such, just as a Cox .049,

Black Widow? Cox_210

Can anyone tell? no-one else bothered to bid, so I'm assuming its not, Oh well, I'll not cry too much!

Well Bugger me sideways Wilf
That's my Black Widow complete with 'odd' cylinder.

I'm very happy about that cos it means that some
must've made their way here built like that.
So far (and this is the problem with the woefully
lacking internet 'info') it's a pre 1983 back plate
with who knows what. The only clear thing is it's
not clever putting too much trust in the sparse
web info out there at the mo.
In my opinion.

So, it IS a Black Widow! I'm very pleased about that! a £6.00 Black Widow! It remains to be seen what condition it's in when it arrives from the States, but basically it seems a good buy to me! That strange looking head had me worried, but as you say, obviously they were built like that.

Aside from the slitted cylinder it looks just like the one that I have in hand at this moment including the cylinder head. I know mine to be correct because I bought it new.

Got two of them that are exactly the same. They only had a bigger plastic spinner. They came with slitted cyllinder, mounted on a graupner airplane.

The slitted cyllinder is original

Was it intended to be used as a "pusher" as well?

Yes that means it is most likely a pusher or someone was using an electric starter on it.

But those engines mostly have brass driveplates and I am sure they should not.

How strange, cause the black widows are fabricated like this by cox! (Not sure about the queen bee.) They where not pushers.

What is the diffrence with the brass driveplate?

Most are not brass.
They have less friction than normal ones.

No

Well then it is not a brass one as i think none of the brass ones were hex.
Another reason it cannot be original on newer engines.

I just dont get it anymore.

It would be coincidence if i obtained two black widows, that both came from a diffrent seller, where modified exact the same way. they both have the slitted exhaust ports and the brass plate.

I got an picture in the manual from the airplane which on of them was supplied with (early 80's), where you can see the slitted ports. However those pictures do not contain the brass plate. But I do think they where originally equipped with them.

I will get on black widow hunting on ebay soon. Now I just want to have a normal original, big exhaust port and normal driveplate engine as a runner.

Bastiaan I think some
Must have been made with slit, some must have been made with brass drive plate but the slit ones came with a hex prop driver as that is the era because the two parts co incide.
Thai is confusing for me too I feel I must check my sources of knowledge.

I got one nib with the slit ports, from the leisure dynamics era.

THe runners i photograpphed where from the early 80's and came with the big spinner. Maybe they foresaw at graupnet that electric starters would be used on the big spinners and equipped them with the brass plates.
