Hi guys i got this on ebay
http://www.ebay.co.uk/itm/140612443986?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_856wt_1193
i know they come with super bees i was wondering if it was worth removing the engine and putting it on something else.

Probably around the same RPMs as a good Babe Bee. The only difference I have seen between a super bee and a babe bee was the #1 (or P-40 on early models) cylinder instead of the #2 cylinder. Personally I would leave the engine in the plane and hang the plane on the ceiling or put it on a shelf. Maybe remove the engine to run it on a test stand for fun and then put it back.

Are the planes at all rare in this condition?
I won't try and fly it without any CL experience don't worry about that Smile

Oh my goodness... that brings back memories of flying around over the clay base paths of the baseball field of my junior high school. I had that exact version of the P-40. I didn't know a Babe Bee from a red-backed product engine like my black Stuka had, but it flew good for a plastic plane. By then I was getting pretty proficient at roundy-round flying so it lasted a long time... in plastic plane years.
I always used my schoolyards to fly, so at recess at elementary and junior high, I used to walk around and occasionally find pieces of my planes. That's when I became such an expert gluer.
Was that Babe Bee different from an ordinary Bee? I've tried to figure out where all my engine parts originated, but no way to be sure.

Yes the super bee had dual bypass ports and I think a boost channel/flute so performance is slightly higher than a standard babe bee and a re considerably rarer as they only came in this model if I am correct.

Hi Nitro,

Nice P-40! Admin is right, wipe that baby down and put it on display.

The "Super Bee" should put out a little more RMP due to the twin intake ports.

That's useful info guys and Mark I will hopefully soon be a member of the 049collectors group (if my membership is accepted).

Yep I'll put her on display.

I have a Babe Bee with P-40 stamped on the cylinder. Don’t remember how nor when I acquired it. (Never had the P-40 plane). I guessed, but wasn’t sure, that it was an engine intended for the P-40 plane. Didn’t know till now that it is apparently the equivalent of a super bee.

Is this numbering unique, i.e., are there any other engines that have the plane # stamped on the cylinder rather than the usual single digit designation?

I believe that is the only cylinder they stamped the plane on the cylinder. The P-40 cylinder should have the same porting as a Black Widows #1 Cylinder. I know they used that #1 cylinder on #290 product engines as well.

Babe Bee - Blue Can:
6x3 / 13,000 / 3.7 / 9.7 / .0477
5x3 / 17,500 / 2.5 / 9.9 / .0434

That is a significant difference.

6x3 / 14,500 / 4.75 / 13.8 / .0684
5x3 / 18,600 / 3.7 / 13.5 / .0682
