Flight Cox Killer Bee Piston Cylinder / Tee Dee Frame RC Carb

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Engine includes a V shape flywheel with the rod pin drilled out originally made for the TD .050 RC to up rpm for a none SPI engine using a muffler - Note I am using a Galbraith glow head with Nelson turbo plug.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. This will be a two part vid for reference once the engine has been broken in a follow up video showing the final results using crank case pressure. 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. Galbreath adapter head for the Nelson plug used.
28in span 88 sq. in. 10mm thick airfoil at the wing saddle.

Wow! You can see why they call this engine range killer bee, amazing bit of cox engineering! Great to see

[@EnglishTurbines]

Used to fly our Single Channel models using Cox Babe Bees back in the day...Like 1968....lol.

[@afrog2666]

Really cool to see people still running Cox engines, really takes me back to when I first got into rc flying, with 2ch car radio and standard servos in a scratchbuilt balsa plane :) I still have three cox engines. A queen bee, a venom and a pee wee, all original. Kinda wanna make something small and fast right now :D

[@christophernoto]

Beautiful! I flew Cox .049 control line planes when I was a kid, back in the 60s! 👍

[@Jimmyzb36]

Wow! I have never had such a reliable high performance flight! From a TD or anything else! Very impressed!

[@cha3119]

AA, You've really developed quite a program with amazing plane and engine design. Very impressive. You have that engine tuned out great with all the mods you made. Really something.

[@Calvin-xp4qp]

1/2A greatness!

[@AmpAbuser]

I am registered with the FAA and I am flying outside the 5 mile zone nothing irresponsible there. I fly less than 300 ft or the plane would be too small to see. Perspective through understanding is key = )

[@chrisbailey4254]

Bloody nora that thing is rapid !!!

[@aeromodelisme45]

Waouh ! il à une pêche ce moteur...et sympa le petit démarreur ! vive les moteurs Cox

[@ronitsingh85]

beautiful, pretty small electronics, what an engine, the carb is sure useful, you can ideal the engine and have a controlled landing, pretty neat, This is the first time I have seen an implementation of an electric starter on a cox!!!

[@donaldparlettjr3295]

God I miss the sound of a Cox engine. Has the sound of one seriously pissed off hornet. Oh yeah you need to carry two items with you at all times with a Cox one a small wash cloth to throw into the backward engine start and bandaids for prop knocked fingers. But smiles all around.

[@fortknoxguy]

Fast little bee!

[@AmpAbuser]

Thank you , You can do a search for 1/2A Skorch for the design and build thread tons of data and testing on RCU.

[@OkiThumper]

Wow, that really moves out. Perhaps a better name would be, "NitroAbuser"? 8-)

[@rebel6910]

nice job

[@OkiThumper]

Wow, that's a fast flight, nice job on the engine. Would make a good pylon model. Turn left and go fast! ;)

[@AmpAbuser]

Thank you George I encourage you to see the Lil Speedy with a TD .049 I recorded this effort the following summer: 117 mph. kzbin.info/www/bejne/a5OmpaJor8l6i7s

[@AmpAbuser]

Thank you Jimmy, I was using 25% nitro and 18% castor no synthetic. Brand was by Arctic RC Fuels -907-394-6276

[@MauricioB71]

Hello , very good video !, I ask ; onboard battery that uses the model for the power supply RC ?? Thanks .

[@claudenicoli9601]

excellent 👍

[@mistermacgray]

Where did you get the plane body from? Also what do you use as a fuel tank? I have two tee dee .049 engines from my dad that have never taken flight but I think it's time that I do that for him.

[@Jimmyzb36]

Electric starters seem to help!

[@AmpAbuser]

Yes Jimmy the 1/2A Hornet Starter is perfect for engines from .020 to .10, I have started two TD .15's with it but it's a bit of a load on the 05 size can motor.

[@volador688]

hola de que esta echo el modelo y de que es el carburador

[@volador688]

hola tenes planos de este modelo que me gusta mucho saludos

[@iggi70]

Kit or plans for the plane? I have some some norvel rc .049 and .061.

[@Jimmyzb36]

Impressive,,,, what fuel?

[@cameronlian123]

Yea buddy thx.. I subscribed..

[@AmpAbuser]

Thank you, if you get the carb having throttle is a big plus they also sell the exhaust throttle sleeves too.

[@cameronlian123]

i dont like those because its just a restrictor/choke, not a true idle. still burns the fuel constant at full throttle. but its a novel idea thats way cheaper

[@MauricioB71]

Hello !, which plug you have installed on the engine?

[@AmpAbuser]

350 mah nimh AAA 1/3 size

[@bilchiri]

hi, what kind of glow plug did you use? thank you

[@AmpAbuser]

Galbreath adapter head for the Nelson plug.

[@ImNotADeeJay]

so you can't throttle it, you must keep flying until it runs out of gas, is that?

[@AmpAbuser]

Yes can throttle has a RC carb rather than a venturi see the start up setting of the needle and throttle set up this was a new engine so needed to fiddle with it a bit to set up the carb.

[@cameronlian123]

what carburetor is that? where did you find it?

[@AmpAbuser]

Cox new production of the original TD .050 RC version, here is a link enjoy! www.exmodelengines.com/product.php?productid=17607&cat=252&page=1

[@joeys5429]

lean

[@IBICat]

EEEEEEEEEEEEEEEEEEEEEE

[@gabrielhuang2343]

it flew too far see nothing !

[@AmpAbuser]

Sorry you could not see the plane, many passes right in front of me . Best watched on a computer monitor where the plane is visible the entire flight 1080 HD / 60 fps. =)

[@joeys5429]

y r u flying in vicinity of passanger aircraft that's I responsible

[@rafaeltorres2886]

Check the rules flying near an airport as long he lets the airport know were he is flying and at under 400ft he is golden.
