Default Magnum XLS Engines

Just getting back into flying after a couple of year break. I always ran O/S and TT nitro engines and im not really wanting to jump into electric. My question is what is everyone expierence with the Magnum XLS line. I had a couple of magnums in the past that just were not that great, but reviews of the newer stuff looks good.

Thanks everyone
Shawn

I have a Magnum .61 two stroke that I bought new. It gave me some trouble at first. Didn't seem to want to respond to the high-end needle adjustments. It would run way too hot. But after 3 or 4 tanks of fuel and some adjusting of the low-end needle it got better and better. Now it runs great! Seemed to need a little longer break-in period than some engines.

I also have a used Magnum .52 four stroke that I bought off Ebay. It has run great since day 1! I never understood why the guy wanted to sell it!

I have 2 Magnum 91 four strokes, and my flying buddy has 2. They run great with no issues. Both are inverted inside cowls.

Thanks for the feedback everyone

I've got 3 .46 XLS engines. If they're broken in correctly, run on 10-15% nitro, 16-20% oil, and with a medium to hot glow plug (i.e. OS A3 or A8) they run fine. The only problem I've experienced with them was that one of the carb hold down screws vibrated out, even after applying thread lock. This caused the engine to run too lean. It ran fine on the ground, but would quit after a few minutes airborne. So like any engine, you need to perform period checks to make sure all the crankcase/muffler/carb bolts stay tight.

Powerwise, the .46's seem to hold their own against other 46 sized engines. I've been flying a H9 Arrow with a Magnum 46 with a 10x6 Evolution Prop. A friend at the field has the same plane with an OS 46 with an 11x5 prop. We've both flown each others planes, and he thinks mine's got more power, while I think his has more. Go figure.

I think the last .46 I bought was $49 on sale at HobbyPeople. For the money, they're a good engine. If you need more power, their .52 XLS 2S is great. They seem to be a bit more finicky to break-in that the .46's, but once they're running... impressive!

I've got a .46 xls on an Avistar that I use quite a bit for teaching people to fly. I bought it new almost two years ago and it is still running like new. It's probably had eight to ten gallons of fuel thru it so far and most of that has been with a newbie on the buddy box. It runs great on 15% Omega, #8 plug, and 11 x 6 APC. The only "complaint" I've had was that for the longest time I couldn't get it to shut off, even if I forced the barrel closed by hand. I had plug the intake or the muffler to kill it. I finally just took the carb completely apart and coated everything with lithium grease, which solved the problem. Other than that it's been a great engine, especially for the price.

I had a very bad experience with two Magnum XLS-46As several years ago. They would not maintain a needle setting, would not idle reliably and would not shut off. Recently I have heard nothing but good things, so maybe Magnum has improved their quality control.

Personally I would spend the extra $$ and go for a Thunder Tiger, OS or Enya. The Enya 50SS is my favorite.
