Introducing the Bone Fish

Following up on lessons learned from my Albacore and Cross-Over designs, I set my Design Goals for a light weight symmetrical design VTPR ship. Applying some of Justin's success from his Buzz, I laid out a symmetrical fuselage design and cut out my foam blank. Target flying in the stronger winds of the Bay Area, I reduced the wing span and chord design to minimize drag and perform in higher wind velocity.

Target weight under 10oz with Pull/Pull Stab & Rudder and 35% Ailerons.

The fuselage design almost demanded a fishy scheme and I have to credit the old Tom & Jerry cartoon series for the idea of the Bone Fish, as the Alley Cats searching thru the garbage cans always pulled out those fish headed skeletons

Time to start inking the fuselage,...I still like using the Sharpies and moved to the large Chisel Tips for covering a larger surface area. New stuff protects everything with 3mil.

Fitted with the wing for a final finish look

Dremel cut a carbon fiber plate to make extended servo arms for the Pull/Pull operation.

My thru-fuselage placement of these servos may not have left me enough clearance on m y Rudder Pull/Pull lines. Some modification may be required.

Use a couple of plastic clevises attached to your extended servo arm to set up your pull/pulls. If you need to adjust the tension just unhook the clevises and twist the line.

I usually mount my rudder servo vertically to avoid dealing with a long & short pull/pull line. You may find a good placement for yours behind the wing or far enough below/above the ailerons so that it won't get in the way and you will have the ability to easily work on it.

Unfortunately I don't believe you're going to have much luck as far as more performance in big wind with the change in wing design. You will probably find a higher potential roll rate though. The weathervaning fuselage is the biggest hindrance there, whether it's thick or thin. In fact a thicker fuselage with more of an airfoiled shape would be your best bet.

This 12 oz Swiss Fish here had wings with a thinner chord and airfoil, and it was a fair bit slower than the buzz (at 9-10 oz with a fatter chord and airfoil).

Jivin' with the Breeze (8 min 12 sec)


Anyway, really cool project Chip. I'm excited to see others going this direction.

Picked up some Braided Line for my Pull/Pull,...

....instead of using the Dacron Fly Line I've used before. Crossing my Stab lines and just transitioning the vertical to horizontal orientation on my Rudder lines. I'm running both sets thru the head of a small Wire Tie, which I've CA'ed into the fuselage to help guide and keep them taunt against the fuselage.

Taped my 1000mah 6V AAA battery pack up front to achieve a 10oz AUW

I cut out and drilled the Aileron control horns,...

....and fitted my control rods. Just need to make a couple Z-bends and adjust my servo trim.

Time to start thinking about the routing of my servo lines to the Rx side of the fuselage and bundle them.
