XY 50cc A-Spec Gas engine

The 50cc A-spec differs from the C-Spec and with most other gas plane engines of the same capacity because of its highly refined head design and casting. The cylinder head of the A-Spec is cast using an extremely accurate process which results in a lighter head with the same cooling efficiency as larger thicker cylinder heads.
XY engines come with a CNC milled crank case and a Walbro (Japanese) carburettor as well as a 2yr warranty on the electronic ignition parts & 12 months on all mechanical parts.

Specifications.
Weight: 1.62kg
Capacity: 47.68cc
Bore/Stroke: 45 x 30mm
Spark Plug: NGK-BPMR6F
Carburettor: Walbro
RPM: 1500 - 10,000
Power: 3.5kw @ 10,000rpm
Suggested prop: 20*10 ~ 22*12
Oil ratio: 25-40 : 1 (Octane of 93 or higher)
CDI Voltage: 6.8v MAX (6v is best)

This is not a modified scooter motor. It has been designed purely for R/C large scale aircraft. Unlike most other gas plane engines built in the region, this motor was designed, milled, lathed, forged, cast, tested and assembled with the single goal of providing the best power to weight ratio, needed for big scale R/C planes.

el motor tiene un par de detalles, la culata del cilindro viene para bujia de asiento plano y trae una bujia de asiento conico, para reemplazarla hay que cambiar el conector de bujia del CDI.

El cigeal me vino con el agujero descentrado.

Luego de resolver esto, el motor funciona muy bien, arranca enseguida, y tiene fugas de aceite en la junta del escape.

por lo demas esta bien, es muy recomendable para quien tiene conocimientos de mecanica.

Five stars, Price being a big factor for this engine makes it 5 rather than 4 stars. It is nice that you can flip the carburetor over because the intake manifold doesn't supply the pulse for the carb's fuel pump - this is supplied by an external line and crank case tap. The short arm on the carb is very easy to hook up a throttle control rod (not a problem at all like is mentioned from another reviewer). The machinework is very nice for the crank

Plasticjoe, it worked great on my obsession and so much cheaper to fly. I had to move the battery to the tail to get it to balance without adding weight. The plane is still a floater with good wing loading so can practive pattern stuff on cheap gas instead of expensive glow fuel. I have another one in standby for something else, whenever I find it and the time to put it together, so many planes, so little time!!!

Question..... what size planes are you guys using this on ? I am thinking about a SIG Sundancer giant scale.... think that would work with this motor ?

I purchased this engine back in mid-April and today I tried it for the first time. It started easily after 5 or 6 flips of the prop. I did not touch the mixture screws. On a 16-6 MA prop and fresh fuel @ 30:1, it ran up to 8100 RPM. The low speed might need some tweaking as it gets rough below 2100 RPM but the transition to full speed is very smooth. I ran a 1/2 litre of fuel through it and did many starts. 1 or 2 flips and away it goes.

hello, this engine is a bad beast, I've run in, four hours, and has not yet been released, has 40 C, maximum temperature at 3,300 rpm. in the second hour, and a helix of sonic 22x10 Graupner, a top speed and with high fuel oil 3 took the modest figure of 6,900 rpm. maintains an excellent relent, a good response and acceleration without touching needles, I recommend it wholeheartedly, a greeting, Alex

This engine has been a great value. It runs better now that ever and the power is awesome! I will buy another one when they are restocked. A silicone wrap is good addition to insulate the high voltage lead. Do not cross the high voltage lead with the hall sensor or the engine will cutoff when you raise the throttle up. Enjoy it.
