Well last Saturday I made it out to the field to do some mowing and flying.  the Minor's and Rob Hein were there already.  After mowing enough to be able to fly I parked the mower, besides it was starting to make noises, now know bearing has went bad in mower deck.  But, back to the EVO 36.  It is kind of strange looking the way the case is molded.  Had it on my test mount.  Started with Top Flite 9X6 power point.  Fuel is SIG 10% half and half oil.  Had the big muffler on the engine.  Took awhile to get it started and it was winding up(no tach as battery went dead), but, wasn't worried as plenty of smoke was coming out of the muffler.  Let it cool and refilled tank and tried to start.  Dead plug.  Changed plug to a Fox Idle Bar and all it would do was just pop and kick.  Finally Howard Terrell let me use the electric finger.  It started and same type run as needle was opened as far as the limiter would let me.   Another blown plug.  So I went with the SIG #3 plug and it still did not want to hand start.  Howard suggested I remove the muffler and the limiting pin.  Three flips and it was running.  I then opened the needle a good two turns to get a for cycle out of it.  Without the muffler it starts like a champ.  Howard then suggested I put the small venturi in or drill out the venturi that came in the engine and go to an OS Needle Valve assembly  which I think I will do.  More on this as it may go in either the Moon Gieseke Nobler or the Brodak ARC Vector 40.  Still have a lot of work to do in the shop.  DOC Holliday

EVO .36

   I put my EVO in a TF Tutor II. Worked best with the small venturi. I used  several props, APC 10.5x4.5.

Engine ran very well. I got rid of the limiter. Used lots of fuel!!! It may  not be broken in yet. I dont have any 5% nitro

I may be able to get a 6 min  run then. I was using Powermaster 10 %  18 nitro fuel.  I will try some 3 blades and

other fuels in the future. It did fly the Tutor II ok.

I just put mine on the test bench and following the advice here, small venturi, removed limiter, 11/4 power point. With the electric finger I only hit it twice and it ran. Had it at 8600 seemed fine, used some old 10% Omega. It will go in my ARF Nobler as I previously had a Mag 36 and the Evo matches up.

I can't add much to the very informative reports about the Evolution 36, but, for what it might be worth, here is what I have so far experienced.
Based on early reports, I immediately switched to the smallest venturi.  I used the stock remote NVA, did nothing to over ride the NV limiter, and used the stock plug. I used the tube muffler and muffler pressure.
I used 5% Omega to which 2% castor and one ounce of Aero 1 were added.  I must say that it felt very strange using pink fuel with so little oil as compared with the Power Master GMA fuel that is used in all my other motors.
For break-in I used a carefully balanced Zinger 10 x 4 prop.
I decided to start the break-in with the two minute heat cycling technique with a couple of brief fuel line pinches to increase the revs.  The first start was a two-flipper and the motor ran smoothly.  The needle valve was adjusted to get a strong four cycle run at 10,400 rpm.  It was apparent from the start that this is a strong motor.
After a total of eight two minute runs the runs were increased to four minutes with several 10 or 15 second two cycle bursts (using the needle valve) during each run.  The motor responded almost instantly to changes in the needle settings and solidly held the needle valve settings.
During the last several runs I turned in the needle valve as quickly as I could to the stop and let it run there just long enough to get a tach reading.  The transition from a solid four cycle to two cycle was almost instant and there was no coughing, sputtering or other complaint.  With the needle on the limiter the motor peaked at 11,500 rpm.
Throughout the break-in I was surprised by how cool it ran.
Based on this beak-in running you might say I am, so far, delighted with this motor.  Although I consider it ready for flying I want to experiment with props before putting it in the air.  I fully expect my delight to continue.  If my experience with my second EVO 36 is the same as with the first I will be one happy camper indeed and will feel indebted to Pete Bergstrom and Horizon.   

Leo,
Give us at least a hint as to why (for those who don't have one)!

I am now using the large venturi with a Super Tigre needle valve assembly thru it. Works good.
