We know that - thanks also to the inter-changeability of parts - even  COX often combined parts in the same engine type and this is why a plethora of various engine combinations exists with thin wall, thick wall, stepped wall cylinders that are either tapered or not, anodized or un-anodized parts, plastic and aluminum carbs. etc.

The "tach" is an Americanism I learned here on CEF, meaning to measure the engine rpm with a tachometer... Smile

No friend, in no way has caused me frustration, on the contrary, I am grateful to You and to all who contribute information to know and be serious in an issue when speaking.
If I present this engine to my friends, or with a photograph in the monthly photo contest of CEF, I would like to call it by its real name ... but I do not know how to call it ... it is rare ....

If measured at rpm, give 15000 with 5.7 x 3 APC with 20/25/55 castor / nitro / methanol

I'm going to ring the bell to the ESTES factory, they probably give me an explanation hahahaha Very Happy Very Happy Very Happy

You may want to call it "Cooler Bee" as this does not run so hot as a Killer Bee? Very Happy

Mauricio,

as New In Box (NIB) engines, they typically sell at high price level on ebay. I am not sure what their market price is. As far as I am concerned I prefer buying TeeDee-s NIB in chrystal box at around 75-80USD plus shipping.

I also like to build Bee type engines from parts I buy on ebay or from Bernie.I have a few NIB TD049 cylinders (stepped wall design from the 1970-s) with pistons, that I will assemble into Killer Bee type configurations with the red backplate.-

These are the strongest reedie engines

I understand perfectly .... I have bought these engines in good faith, with their boxes, with their manuals and with the backing of the manufacturer that announce it with the name of Killer Bee, so I have two Killer Bee one .049 and another .051 . If there is a difference, it is not a problem for me as a customer, but clearly for the manufacturer ... and if they would be active now, it would be a good topic to discuss ...
mmmm .... (I think), I'm happy to have them! cheers Small Cox Logo

Mauricio,

the engines sold from Corona, California date back to 1990-96 when COX moved in their new headquarters from Santa Ana. COX was called COX Products between 1993 and 1996 so as your box shows COX Products, this is from that period.

So your engines are not from the later, Estes period, and as such, represent - in my eyes - a much higher value than what Estes may have sold when - as someone explained here once -  hastily put components together from whatever they may have found in their stocks to sell out ...maybe I see it wrong.

That is why I am happy with me, I have acted in good faith, pay every dollar I was asked and defended the Cox brand out of respect to those who from the beginning have done things well and off ... I suppose if the Cox factory would see this post now, I would try to solve the problem, (if it really exists), I do not have what the manufacturer says he sold me, they would probably send me the corresponding pieces for the sole reason of maintaining their HONOR, so I assume and feel it.

Hi Brad the KB is a beauty but are you not concerned with the standard plug that in my experience robs power from 049 size engines? I would rather go with the drop in type insert.

Hello Balogh

The new pic is with a high performance Galbraith racing head and Nelson Glow plug
Good for another 500 - 800 rpm on average depending on engine type. I have had
good numbers with the stock Cox high compression head, I have only tried the insert
plug types with my Norvels.

Brad, you have an original Killer Bee, where RPM should run the engine with a 5x3 Cox propeller, like the one I put into my experience? ... thanks! Huh...

I will bench test the engine as shown in the last pick and vid the effort.

I have not ran the engine as a reed valve I have ran it as a Killer TD  Small Cox Logo

Vid of the second engine run was doing a break in by flying rather than on the bench
NV is a bit rich since this engine has less than 1 oz fuel ran through it at the time of the vid.






AmpAbuser
Published on Apr 5, 2015


I am breaking in the engine in the air with a APC 4.5 x 4
This is the second engine run 20.5k rpm in the hand and best level
pass at 24,160 rpm needle is set bit rich. After a few more runs I expect
a fully broken in engine getting about 25k needle peaked.

Engine includes a V shape flywheel with the rod pin drilled out originally made for the TD .050 RC
to up rpm for a none SPI engine using a muffler - Note I am using a Galbraith glow head with  
Nelson turbo plug. The Killer Bee is a original May 1995 engine bought new never used. I robbed
the tapered piston and cylinder for the TD frame comes with SPI function which can be heard on
start up with a notable tone clearing burst of power. Note the Killer Bee has a lighter piston
weighs .5g less than a stock .049 piston. Installed a phenolic thrust washer for electric starter use.
Run time in rich mode 1oz fuel tank 25% nitro 5 mins 44 sec.
11.4 oz plane 5 ch with flaps / rudder / ailerons / throttle / elevator.
