Well I tried the engine today, It is a lot louder than I was expecting. I might have to make a glass pack scilencer for it. With the choke on, It fired up after maybe 6 good flips, than 4 or 5 more with the choke off. Idle is insane, nice and low, there is some lag in the mid range after ideling for a few mins. I think the engine is loading up and needs to clean it self out. if I go from idle to WOT, there is a bogas it passes mid, but did not give any sign of quiting. If I give it a blip on the throtle, there is no mid range lag.
One thing I noticed is that when you come off WOT to idle, it takes some time to idle down. It will drop to around 3k and stay there for 10 - 15 seconds than drops down to idle. It might just need a carb adjustment.I have only run a few OZ of fuel through it, maybe it will clear up when it is better run in. It is nice not having to carry a glow driver with you anymore. I took it for a few laps up and down the street, shut the engine off, give it one good flip and it is back to life. I am going to love using Gas. I have my eye on a ESM FW190 71" and am thinking of a 30CC gasser now. My satio 1.25 has maybe 1 1/12 gallan of glow through it and not sure if I am going to keep runnig it or switch over to gas. It is that nice.
I put the T60 on the ballancer and was not happy, With the plane ready to fly, I needed to add almost one pound of weight to the nose to bring CG to 4 1/2 inch from LE.Using the highly accurate bathroom scale method,( have to pick up a good fish scale) I have put on 20 pounds in the past few months and the tiger is just over 10 lbs. Both numbers were a shock to me. With the extra CC of the DLE will help with the extra wing loading, Just a faster landing speed
If the weather is good this weekend, and not snowing I might try and do a maiden on Sunday....if not, It will have to wait until spring as there will not be many more good days until the snow.
Pit viper 1.... I used a brass prop nut/spinner. It helps a lot with low RPM vibration. the DLE did not seem to be shaking the Airframe much at all from idle up to taxi, and no vibrations above that.
