Yo he comprado este motor para montar en un biplano de 1,80 y en el rodaje veo que es fantastico
va muy ligero y el ruido es sensacional.Very happy with engine.The bosses on the mufflers are not good and should not be used this way as damage could acure to the bosses on the engine itself.Correct this by sanding the muffler bosses on a double thinkness glass,with sand papper in an #8 rotation pattern and all the paint is gone,and surface is true and flat. Then they can be used. The prop adapter holes are to loose and sloppy where the bolts mount. I still give it 5 stars,its a nice engine for the price. Thanks hobby cityvery nice engine, but with some problems. Do not run your engine with the supplied mufflers as they come, because the bosses are not flat and true and could damage the exhaust bosses on the engine itself. This can be corrected by sanding the mufflers first, on a piece of double thickness glass and using a good sand papper in a #8 rotation untill all the paint is gone and the surface is true and flat. Then they can be used without damaging the exWow! Great looking engine! Mine arrived quickly and had a alum. colored crankcase. First trick: Use small amount of CA and glue the drilled washer to the prop to serve as a drill guide as you modify a $40 wood prop to fit the thing. Use a new drill bit so you don't split the wood! I backed mine with scrap wood as I drilled it.5 starsExcellent engine with enormous power and a realistic sound. I power my Jamara Zlin 526 with it and I'm very satisfied with itRecieved motor today. Gave it 4 stars because I haven't run it yet. Looks great. Has the 2 mufflers with gaskets. Mufflers are 1.980" in Diameter and 4 3/8" long with 5"long 1" round Stacks. The Hall effect switch is enclosed in a molded plactic bracket and has a Futuba servo connector 3 wire. The igntion module plugs into this connector. It also has a Futaba servo plug for the 4.8Volts. The prop adapter is aluminum 1.375" diameter and has a spiral knurl on the front of it where your spinner or prop mounts. The prop shaft is that 10 MM fine thread with a hex nut and has 4 socket head cap screws, the metric size just larger than 6-32 on a .5512 radius bolt circle. The walbro carb is a size just larger than a US 41 stock carb. The total weight of the engine and ignition is 2091 grams or 4.609 lbs. I only bought this motor because I thought this was a JOKE for this money. It's no JOKE and I'm Tickled with it. If anybody wants more information you can E-mail me At
This engine is perfect. It starts easily and is very reliable. With 22/8 prop it turns at 6500rpm. I use it in Jodel Robin DR400 model with a wingspan of 2.45 m and weight 8.5 kg.
I use it as an aerotow, which can easily tow a 6kg gliders.
I am very satisfied.Schner kleiner Boxermotor, springt sehr gut an. Leider sind die Schalldmpfer in Deutschland nicht einsetzbar da zu laut.
Ein guter Motor zu einem noch besseren Preis.
Great engine. Easy to switch, and not just noisy vibrancy. During the most extreme stunts turns off.much better than expected, nicely made-will run when the weather gets better for full report
