On Monday my mate Steve (steve111) and I gave my Enya 19-V some flights in his 360 square inch or so profile stunter, in place of the Olly clone that was in it previously. The 19-V had been chosen as it was a close match for the Oliver Tiger mount pattern, and seems to have similar performance.

I was running a Taipan black 9x4, Enya #3 plug, 5% nitro, 22% oil fuel. The oil was mostly castor with a bit of synthetic in it. Launch with it running in a slightly rich two stroke, RPM had previously been tached around the mid 11,000s with it running that way on the bench. No muffler. The tank was a conventionally vented Brodak 2oz.

The verdict is - absolutely wonderful!!!

After launch it picked up revs noticeably with just a hint of richness still, and proceeded to give a nice even run throughout the entire flight, only burping a couple of times on some tight maneuvers, and for a lap or two before cutting out. Steve and I each had a couple of flights, and really enjoyed the performance of the engine & plane.

Alas, after lunch we stuck his David Owen reworked Olly back in it, had a bad run (too rich or under compressed), and lost the plane to a wind gust while flying upwind with marginal engine power. I will be building another of Steve's design, as I want to get that Enya back in the air.

We were running two circles and managed to get two Enya powered planes airborne simultaneously - the 19-V and my friend Mike's SS30S powered ARF streak. The contrast in exhaust notes between the unmuffled 19-V and the muffled SS30 was stark. I like the old one better (but the SS30 is a great engine its own right).

cheers,
Colin
