I've have had great success with my PTS, and .46 Evolution engines, especially after removing those @$!#$ limiters.
The NX 1.00 has been a nightmare for me.
I've never been able to get this engine to run reliably for any length of time.
I've gotten quite good at getting engines tuned up, rebuilt, check out, etc., so much so that I am frequently sought out for aid with problematic engines, as I can typically get them running well...
Not so with the NX 1.00.
Pump, replacement tanks, header tanks, replacement carbs, stiffner springs, new heads, longer plugs, etc. etc. etc... the NX 1.00 has been a "deadstick king" for me.
Next time I consider an Evolution in this range, I'll go with the GMS 1.20 instead... much cheaper, reliable and more powerful.
The Evolution NX 1.00 is A LEMON!!! I'v had one...the last one I'll ever own...and it left a bad taste in my mouth about the Evolution brand name. I speak at length about this engine (basically trash it[>:]) on another thread. The glow plug that came with it would not keep the engine running for more than 10 seconds so I switched to an O.S. F plug. Then I had to remove the needle limiters after they were supposed to be 'factory set'. Then after about 50+ deadsticks in my H9 Funtana 90, the carb fell off in flight. After finding the carb and bolting it on again, the engine ran worse than ever. It sits on the shelf now and would be the very last choice of engine I would use for anything. Period. Want to practice deadsticking your model airplane? Bolt this bad boy on and go at it.
