I have this engine on a 72-inch trainer. Both the airplane and the engine are entering their sixth year. This combo is my "warm-up" airplane and is a blast to fly as it has gobs of power. It starts quickly, idles very well, and his had zero issues. I have a .46 two stroke and a .52 four stroke that are equally reliable. Properly broken in these become very nice engines and you cannot beat the price. (Posted on 4/21/13)

I had purchased this engine a year ago to fly in my 60 size plane . It's been a great motor with no issues. One thing to remember is that break-in and tuning for this motor is critical to the longevity of this motor. All in all this motor has great power And is priced for the hobbyist on a budget (Posted on 1/25/13)

I have this engine on a Hobbico 60 Mark II It' swinging a 13X6 APC prop on Omega 15% fuel with an OS#8 glo plug. Starts easy and idles reliably. Plenty of power for all but exteme verticle acrobatics. Follow the break-in instructions and enjoy. (Posted on 11/27/12)

This review is for my second .61 XLS. This one is mounted in a Hangar 9 Phoenix 7 pattern airplane. This time I am running it with a Mac's Products 10cc Quiet tuned pipe.
The power is great, it is turning an 11-7 APC prop at 14,130 RPM burning Cool Power 15% fuel. Since this in an all synthetic fuel, I add 1 oz of castor oil due to the ABC construction of this engine. Idle and transition are excellent.
Disclosure- I changed out the bearings as a precaution due to the experience that I had with my previous engine, as well as the expected increased loading and RPM from the tuned pipe. I am not saying that this is required.
Overall, I again find this engine to be an excellent performer as well as an excellent value. Five stars. (Posted on 6/18/11)

This is a follow-up to my previous review. The problems noted in my past review have been resolved, and the engine runs like it cost several times what I paid for it. The engine continues to gain power as it breaks in. Reliability is tops. I have run K&B, Fox, Super Tiger, and currently Merlin (2003) plugs- the engine is tolerant of a variety of plugs. Awesome idle and throttle response. While the engine will swing a bigger prop, but an 11-7 allows it to unload and produce some serious power. The included muffler seems to give a slight power boost at higher RPM's. This makes for a great combination for my Classic Pattern airplane (Vertigo II).

These are true ABC engines- they are fit very tight at TDC, they require a longer break-in than some other brands, but the result is worth it. I recommend following the break-in instructions that come with the engine. A correctly broken-in ABC engine will yield superior long lasting performance.

I bought a second engine to put in my Hangar 9 Phoenix 7. I am looking forward to this airframe/powerplant combination.

Finally a word about Hobby people Customer service- First Class! They took care of my parts needs quickly. They were very responsive to my needs, and that is always appreciated in a world that seldom cares about customer service.

In summary: A rough start has turned into a rewarding experience with both the engine and the company backing it. I will recommend this and other Magnum products without hesitation. (Posted on 5/9/11)

I have had this engine for two years. It always starts and runs good. Even after nose diving a plane at 80 mph the engine still ran and nothing was bent.
I would purchase again without question. (Posted on 1/3/11)

The engine is very powerful, idles very reliably, and the throttle range is quite smooth and linear. The engine is mounted to a classic pattern airplane, and turns an 11-7 APC prop at 13,200 RPM using 15% Omega fuel. That is the good part.

The bad part is that the front bearing failed 30 minutes into the break-in run. Both bearings were replaced with high quality bearings. The engine, which has 2 hours run time is eating plugs, as the con rod bearings are worn and the rattling top end is knocking out the plug element. I am getting a flight per plug.
I am going to replace the con rod, and keep a close eye on this one.

I have been doing this for 36 years, so it is not beginner's error. For 99 bucks, I guess that you can't get your hopes up too high. (Posted on 12/28/10)

I bought this on the advice of a friend, who also had the Joss Stick that I bought it for. I was expecting it to work just fine but to my surprise it not only worked ok but awesome. started up right away, idled smooth @ 2000 rpm and reached 10,900 rpm during break in which I was running very rich. I leaned it down just a little and it is still about 11,000 + rpm. I´m running the APC 12X6 prop and am looking forward to getting my Joss Stick up soon. The motor has an abundant amount of power for the 12x6 and I might just try 13x6 after I have had a few flights. THANKS FOR A GREAT MOTOR @ A FAIR PRICE. (Posted on 8/30/10)
