Has any used or had any experience with this engine?
Does it run well? Is it reliable and idle well?
How about transition from low speed to high?

Any info is appreciated.

FRom my review (a few years ago) on this engine:

All propellers were Zinger brand wood props with the exception of the 14x8 which was a Top Flite Powerpoint wooden prop.

Here are the results from the 10% fuel test:

Prop Size EGT CHT Max RPM Idle RPM

12x8 365 F 309 F 12,060 2,600
12x10 345 F 269 F 10,740 2,520
13x6 356 F 263 F 11,400 2,220
13x7 333 F 276 F 10,710 2,190
13x8 330 F 305 F 10,680 1,950
13x10 310 F 279 F 9,630 1,980
14x5 344 F 274 F 11,280 1,920
14x6 329 F 294 F 10,170 2,040
14x8 328 F 294 F 9,810 1,980
14x10 291 F 278 F 8,430 1,980
15x6 316 F 305 F 9,540 1,860
15x8 282 F 266 F 8,400 1,800
15x10 287 F 265 F 7,860 1,710
16x6 287 F 271 F 8,070 1,980

Next I changed to the 15% Wildcat and recorded the following results:

Prop Size EGT CHT Max RPM Idle RPM

12x8 323 F 294 F 12,150 2,280
12x10 325 F 287 F 10,980 2,340
13x6 345 F 293 F 11,610 2,100
13x7 325 F 308 F 10,740 2,400
13x8 325 F 306 F 10,680 2,040
13x10 329 F 298 F 9,630 1,980
14x5 328 F 274 F 11,310 2,130
14x6 340 F 285 F 10,320 2,040
14x8 320 F 285 F 9,840 1,980
14x10 304 F 288 F 8,580 1,830
15x6 319 F 287 F 9,600 1,840
15x8 291 F 272 F 8,520 1,800
15x10 285 F 274 F 7,950 1,800
16x6 292 F 265 F 8,190 1,740


Now for the really fun part! I had recently purchased a Sig 4 star 60 ARF for use in flight testing engines in the .61-1.00 displacement range. The 1.00 NX was the first to be bolted to my new bird, and I was really looking forward to it! Since we were still in the winter months here, I fitted aluminum skis to the plane and headed off to one of the nearby frozen lakes for some flight testing. The weather was cooperating, and it was a “balmy” 42 F, sunny and windless. I brought a younger flying partner with me to test the plane also, and allow me to get my in flight photos.

The 4 star 60 came out to 7 pounds and 1 ounce with the 1.00NX fitted. I decided to test the engine using the recommended 14x6 prop (I was using a Zinger brand) and Wildcat 10% premium Xtra fuel. The supplied plug was used in the engine (it survived all bench testing perfectly).

So how did it perform? Well, it did not disappoint me! Even in the cooler temperatures, the engine started (with the electric starter or by hand flipping) immediately and required just a minor adjustment on the high speed needle. The idle was set at a low 2,200 rpm, and top end was measured at 10,110 rpm. Transition was excellent, being almost immediate up through the entire rpm range, and similarly back down again. After a prolonged idle (several minutes or more) the throttle did need to be slowly brought up to mid range, allowing the engine to “clean itself out” of excess fuel in the crankcase, but in the air you could throttle up as fast as you could move the throttle stick (even after extended low speed flight or maneuvers such as spins where the engine was at an idle setting for a pronounced time) and the Evo would respond immediately!
I put the plane through many aerobatic maneuvers such as inside and outside snap rolls, vertical snaps, upright and inverted spins, and numerous rolling and looping sequences. In a nutshell, the 1.00 NX never once hesitated, or skipped a beat. At little more than ½ throttle the vertical performance was spectacular in the 7+ pound plane. At full power, it went up like a rocket ship! I did many touch and go maneuvers - many dozens, and each time the throttle was pulled back the engine dropped immediately into a steady idle. Rock solid performance! Between myself and my friend Brandon, we ran the engine in flight for an additional 60 minutes, burning approximately 40 more ounces of fuel. One could expect to get a 10 to 15 minute flight per 10 or 12 ounce tank, depending upon the throttle settings used.
Measuring the Evo 1.00 NX’s noise level with my Radio Shack digital sound meter, I took readings of 97 dB in front, 92 dB in the rear, and 93 dB off to either side. Measurements were taken while the model was sitting on the snow, running at full power with the 14x6 Zinger prop. Once in the air, the noise level was in no way “annoying” and actually quite low.
