Hi Andrew,
That was a few years ago. I was just out there over the Labor day Holiday. Herb, Gregg, Bruce and quite a few other flyer were there on Sunday.

Is the Hw 730 a 110 mm fan? If so it should work fine, if not at least it will get you in the air and you can always get the DS-75 or maybe even the Stu Max fan.

The Spark is going to be a really nice larger sport jet.
It will keep me flying while I finish the Hun and I have another F4 waiting to be built!
