I am breaking in the
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Engine includes a V shape flywheel with the rod pin drilled out originally made for the TD .050 RC to up rpm for a none SPI engine using a muffler - Note I am using a Galbraith glow head with Nelson turbo plug.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.
