Berkut Roncz Canard

Description

The Berkut canard is identical to the Long-EZ Roncz Canard.

The leading edges come already separated with the corners already radiused for the shear web. The dowel holes come pre-drilled to ensure perfect alignment of the leading edges.

Elevators
The elevators are identical to the elevators for the Long-EZ Roncz canard. I make 2 types of elevator cores for the Berkut, hotwire template elevators and contour template elevators. The hotwire template elevators are
cut per the hotwire templates from the Long-EZ Roncz canard plans. The plans tell you to compare the elevators to the elevator contour templates and then sand them to shape taking into account 0.020″ of skin thickness. I think the hotwire templates are were probably intentionally made oversized because the small, thin elevators are rather difficult to cut by hand. In fact, the plans tell you to cut them in 2 separate pieces and then micro them together. With the templates a bit oversize they are easier to cut by hand and it allows the builder extra material to be able to sand them to match. The contour template elevators I make are simply cut to match the contour templates to begin with. CNC allows me to make much more precise cuts and to cut material much thinner than would be possible otherwise. Some peoople still prefer elevators cut slightly oversized so I offer both. Another thing CNC allows me to do is to cut the elevators full length instead of cutting them as 2 parts apiece as it says to do in the Long-EZ
Roncz canard plans. This means you don’t have to micro the 2 halves together to make each elevator. When I ship a canard, it comes with elevators cut full length. Actually they are slightly extra long to allow the builder to cut them down to fit exactly. When I sell the elevators apart from the canard, they are too long and skinny to ship full length so I have to cut them in half to make them less likely to be damaged in shipping.
