5.5HP 53cc Twin Cylinder Gas Engine

5.5HP 53cc Twin Cylinder Gas Engine

The new 53cc twin boxer engine has two horizontally opposed 26.5cc cylinders providing 5.5hp of low vibration power.
The two cylinders dynamically balance the engine, making it a smoother running and more reliable idling engine than a single bore motor of the same size. Having double the spark this engine not only idles better, it also has quicker throttle response and a much nicer exhaust note!

Take note of the CNC machined crankcase and finely cast cylinder head, this is a quality motor!

Features:
• CDI Electronic ignition with auto advance
• Walbro membrane pump carburettor with manual choke
• Automatic advancing electronic ignition
• Dynamically balanced
• CNC machined crankcase
• Finely cast cylinder heads

Specs:
Performance: 5.5hp
Bore/Stroke: 34x29mm
Weight: 1477g
RPM: 1,900~9000rpm
Spark Plug: CM-6
Suggested Props: 22x8~22x10
Fuel: 2 stroke oil/fuel mix (25:1 break-in 40:1 general use)
 
For more power use unleaded fuel with an octane rating of 93 or higher.
Never power the CDI with more than 6v. Doing so will break the CDI module. Take note of your battery packs true voltage when fully charged.

I have the engine and it runs great. Hard to start the 1st day, but after it runs, I can re start it by hand. has anyone tried running the engine with higher Octane? I'm running regular pump gas 87 and I need to run higher for my other gas engines at the field. will 100 Octane hurt this motor at 25:1 full synthetic Oil?

I run mine on 95 and Stihl ultra.. Had no problems. I also reversed my cyls to get the carby away from the mufflers.. One she done some time starting is real easy.

I have 2 running sweetly on 95 octane with 40:1 mix (running in was 30:1). If your carby is facing down I recommend that you fit a HK 30-55cc Velocity Stack, as it idles a lot smoother with it when your idle is below 1350rpm. I and also fitted NGK plugs for better high-end power.

UMS Seidel 9-90 arrived today, and was disappointed that it did not have the nice presentation box the 7-70 had. Perhaps not much of a surprise, given stories of broken boxes in shipment. Now it's just a plain cardboard box, with some polyolefin foam sheet, pour-in foam at the corners, a big honking polyethylene rod over the crank end, and a bit of shrink-wrap around the cylinders. Very good protection, lousy presenta

qualcuno ha detto che i carburatori laterali sono difettosi nell'aspirazione, probabilmente non s che nei motori areonautici si mettono i deflettori per convogliare l'aria nel modo corretto, provate e vedrete che non avrete nessun problema, anzi avrete un maggior raffreddamento, per aiutarvi sappiate che i fori d'ingresso devono essere pi piccoli come area di quelli d'uscita se volete un buon scambio termico.Naca aperta scambio pessimo

We were a bit affraid of starting it at first. We check every nuts and bolts on it. Did a small modification on the spark pipes to make them a bit tight on spark plugs. In order to give it a sure ground. Used 1:20 (95 octane) mixture , 4*1.2 NiMH battery and a 20*10 Turnigy Cherry Wood Prop.
Made 5-6 turn choke and with a bit of an excitement give it a try. One pull on prop with hand and it started singing. Wonderful Engine! Very recommended!
