Magnum Engines XLS 52 Two Stroke RC Engine (RNV)
- Product Review (submitted on November 1, 2011):
After doing the break in per the instructions (actually 3 12oz tanks for me) I just went
flying keeping it rich, didn't touch the low speed neddle and wow! reliable and never quits, very decent performance, I have it in a great planes sport mustang with a 11x7 apc and I almost keep up with my buddy who has the same plane but with an OS 55AX! keep in mind mine is stil very rich. I'm using the optional pitts muffler and it is great BUT you need to plug one of the exaust pipes or else you wont have enough back pressure in the tank and that leads to an unresponsive needle valve and lean runs. YOU CAN'T GO WRONG WITH THIS ONE! I have several OS and this one is on par except for the price. Oh and even if it's rich with a 12oz tank I fly 15 minutes and still have plenty of reserve to go around another 2-3 minutes. A+ !!
