.91Magnum - through a rod. Review by SteveE-----
Rating
I installed the engine in a Senior Telemaster (old style) and followed the break-in instructions precisely. During the third tank of 10% break-in fuel, the engine made a loud noise and froze up. It broke the rod. Sent it in with explination and recieved curtious, prompt service, (two week turn around). When I got th engine back, it ran great as I broke it in just running it rich for two tank fulls. Leaned the engine a little and just started flying it. It runs great. Been flying it for three months, no problems. (Posted on 8/8/14)
1st one great, 2nd one not so great Review by At6 Flyer
Rating
First 91 awesome performance. Installed it in my Top Flite P47 and after three seasons runs like new. Second 91 not so good. I installed it in a Top Flite AT6. I broke it in as manual recommended using 10% fuel containing castor oil, Omega brand. Just started my second season and engine threw a rod. At least the plane was on the ground. OBTW I'm out of the warranty period.

so far runs great one little issue` Review by Tripacer

got mine up and running today for the first time in 50 years of modeling i followed the instructions on how to break it in even went and bought a NEW gallon of fuel set up as per instructions fired right up was WAY to Rich (would quit if you pulled plug wire off) leaned it out till the HIGH SPEED NEEDLE Bottomed out but at least you could pull the wires off and it would stay running ran a whole tank through (10 OZ) decided to figure out why it would run so rich with the HS needle seated took all apart and came to the conclusion the Needle was BENT and would not screw all the way down with out binding borrowed one out of my Magnum 46 2 stroke and now after 3 tanks i can adjust the needle all the way in or out and i think its time to go fly this beast
im giving it a 3 star for the bent needle have sent an email to there Service dept will see how good the service is should be a slam dunk just replace needle (Posted on 4/19/14)

Lack of parts availbility Review by Single stick

Michel, our apologies for out of stock parts. Please know the crankshaft is now in stock. Matt


91 magnum in super skybolt .Flies great, engine all you need,smooth and steady.. Less than 2 hrs. running time suddenly stops . Remove engine from plane and remove back plate.. Crankshaft pin sheered off as if cut with a laser! 13 month old engineso no warranty. Tried to obtain a replacement part with no luck.that was 4 months ago.. now its December and still no parts..Stick with Saito and O.S. . Mike Melendy, Blue Max R/C flying Club (Posted on 12/2/13)
most reliable engine Review by tom

I have about 8 flights only on this Magnum 91 FS but it has never quit in the air or in idle at taxi in or out. This is m ore than I can say for my Saitos and OS 4 cycle engines. I also have 2 Magnum 52 4 cycles and the are the same for starting and for reliabilty. (Posted on 11/29/13)

This is my second engine. The crankshaft broke on both after about 75, 10 minute flights.The first time I crashed my plane, the second time i was luckiy because I was still on the bench. the engine runs great but this is a dissappointing flaw. (Posted on 9/26/13)
