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 bought this engine and the CDI unit was damaged!!!! Which are the specs of the CDI this engine needs? I have to get a new one...please help!!

I replaced mine with a CH Ignitions unit. It's high energy and works very well. About twice the cost of Rcxel replacements but worth the reliability. A standard CM6 Twin replacement of either brand will work well on this engine. Also Octopus Rc replacement mufflers ($36 pairhttp://www.youtube.com/watch?v=dIjSvWnIDKU

This will be a great motor for the hanger 9 super cub, I use to aerotow with a 108"piper Pawnee fitted with a G 62. Great combo for towing up to 5 meters.

Octopus Rc was the origin of this engine. Try inquiries on parts with them maybe.

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!
