Bruce King has a really nice flying design based on an upgraded Hummel.
It started of off as a $5K, but increases in the cost of aluminum have
run the build cost up a bit. $7K would be pretty close.
The bubble canopy does too, but it flies so much better it's worth it.
The prototype was a little weak kneed, the gear almost retracted on a
hard landing. But that seems to be corrected now.
It performs very well on an 1835.
