I had another fine day at the flying field with the new DL100. What can I say: it’s a hoot! There’s no problem pegging the fun meter with this one.

The carb tunes a bit different from the 50. On the 50, the high speed circuit has almost no effect on the midrange but on the 100, it definitely does. The midrange won’t smooth out with any richness on the high speed circuit. The 50 also runs fine with the needles close to where they ought to be but the 100 wants them set. It’s not difficult to tune, it’s just more sensitive to being out of tune.

Tuned “right’, it’s a bit cold blooded and requires the choke before each flight. It also takes a brief warm up to get the transition not to stumble. Some may consider this a bother but the reward is a very smooth midrange and an absolutely phenomenal transition. This thing responds to throttle like nothing I’ve ever experienced.

The 26B Vess is spinning 7100rpm on the ground now. The way the engine sounds, performs and flies the plane I have no desire to change props. I’ll try some others soon as I’m sure people are wondering about comparisons but I’m having so much fun with it it’s hard to remember to be analytical.

I did remember to keep track of gas consumption. 15 minutes in the air used about 20oz. Remember though that this airframe is on the light side and heavier ones will need more throttle for similar flight. When we start flying the CAP 580, it’ll be outfitted with a 30oz tank.

FWIW, the engine has passed my “test” and I’m going to be happy to sell and support them. Congratulations DL, you have another winner here. Release date has been estimated at May 20th so shipments should start soon thereafter.
