Title: I have my Evolution 60 flying this week
Post by: Allen Brickhaus on August 13, 2011, 02:48:22 PM

           After many trials and time spent finalizing a multiple number of publications, I retrieved my Arcturus I from Byron Barker and with his help fitted the new engine to the Arcturus I. To minimize the number of holes in the side of what was a OS Max .40vf piped power plant, I asked Byron to fit a tru flow venturi of .177" diameter (#16 drill bit) to the Evolution with an RSM ST copy needle valve and a C.F. Slattery tongue muffler.

Three flights have ensued and the repeatable results are such: 5.25 ounces of SIG 10% Champion fuel (20% oil, half an half) with a Rev-Up 12 X 5W prop with a release of around 9900/10,000 rpm. This has given me an average lap time of about 5.2 and 5.25 seconds per lap with a full time (from engine start to landing roll-out stop) of 6 minutes and 40 seconds to 7 minutes. The power plant came on at the tops of the manuevers with a sight "beep". I can see that I need to shim the tank slightly, but would begin to use this combination of the Arcturus I and Evolution .60.

Pulled the 62 ounce 675 square inch bird with no problem.  Good power source for an economical price.

I'll pass that info on to Brian, he is still talking about picking one up for the Legacy he's building.

Yes, it weighs a bit more but I felt the Arcturus I needed some nose weight anyway.

I  intend to write a more indepth report for FM.  I wanted to get my initial views of the engine and its run in Stuka and Stunt Hangar first.

Thanks a million for the report.  Sounds very promising.  Now I'm even more excited to build your Encore for the Evo 60 engine!
