Magnum Engines XL 70 RFS Blue R/C 4-Stroke Engine (11cc)

Product Review (submitted on August 30, 2010):
Bought the XL 70 RFS about two years ago. My first 4S. Had it in an old texan and it pulled it around okay. Recently installed in a hi performance 46 size bipe but it had set for awhile and just didn´t seem to have enough power. Worked with Todd at Global´s excellent tech support and found a couple of things. First read the manual and adjust the valves. There´s an extra 1000+ RPM to be found when you get them right! Engines been a real power house spinning an 11-7 3 blade at 11200 using 15% fuel. Idle is fantastic and transition is excellent. Running inverted in a full cowl doesn´t overheat and a little loctite around the muffler sealed up the little bit of oil blow by messing up the inside of the cowl. Keep the "O" rings fresh and all the bolts tight. Bottom line, like every other mass produced product a little bit of attention and fine tuning has turned out a real Gem!!
