Thanks for the kind words and useful information.

The DH-4 has 4100 square inches of wing and will weigh in the 35 pound range. That figures out to about 20 oz/sq ft. It should fly in a moderate breeze.

But I agree that extra power is always a nice thing to have in your pocket.

The reason I considered the DL engine (aqnd others) is the lack of width in the engine compartment. Any engine with a side mounted carb is out of the question.

Plus the cylinder will be pointed upwards due to the exit for the crankcase.

I have a month or so to finalize the engine choice anyway. I was just trying to do some homework first.

Thanks to all...
