    Will,
    In my set-ups the GT33 with CDI will die on the lowest idle setting so that should be ok. Just set it up so it will. If you ever get into gasoline, I sell a terrific gas line and nylon...

    In my opinion the YS classic was the sweetest runner of the 60 class engines. On 15% nitro, terrific top end, unparalleled transition and very low idle. It was a wise choice.

    Syssa Aircraft has moved to a new facility in South Carolina. I suspect that's the reason for the delay in responses.

    Scott,

    I hear what you are saying. We know that the YS big block 4 strokes are more frugal when being run on ignition. But that's glow fuel.

    3 blader, probably the Mezjlik 20x12 carbon. I used that prop on my DLE55 which was piped. It's a great combo turning just about 7.1K.

    Scott, don't forget that my numbers are on a piped GT33. I see guys reporting much less on the stock muffler, for 19" props. All things being equal, it seems to me the pipe boost is about 1000 rpm...

    Scott, I've run the apc narrow blade 20.5x10 on the CDI/ GT33/ pipe combo. The gasoline I use is Avgas mixed with a good racing synthetic at 50:1. I got 7200 max rpm, an rpm number we don't hardly...

    Sungho,

    Please make certain that you use a pipe on the GT33. The ES Composites 35G carbon pipe is highly recommended. It's the lightest pipe (around 100 grams) available. You will also need a...

    The Extreme Flight 78" Extra is a great match. It has a pipe tunnel built in. It's a large model for a 2 meter. It very light at around 12 lbs. Very strong too.
