Q-talk 158 - Shots of Xpresso!

by Reg Clarke

[ EDITOR'S NOTE: Reg Clarke from Canada may be very short on words, but he is certainly a prolific picture taker and documentor of his beautiful, highly modified Q2. He sent me nearly 100 images of his mods, and because that is too many pictures for a single page to load easily, I am going to break the pictures up into separate articles over the next few newsletters.

In this issue we'll see a brief overview of the what the plane looks like. In Issue 158 We'll take a closer look at his tailwheel and the modifications he's made. In Issue 159 we'll take a look at his highly ingenious canopy latch system, and in Issue 160 we'll see how he installed the 150 Cubic Inch 150 HP Turbo Subaru.

He also wanted to let everyone know that this bird is now FOR SALE! If you have specific questions about purchasing this beautiful Q please contact Reg via e-mail at This email address is being protected from spambots. You need JavaScript enabled to view it. ]


Here is a picture of my new tail wheel on Q2'Subaru N624JC.

For Sale:

Direct Drive Subaru

Tail Wheel Pivot - Bearing races one on top one on bottom from bearing supplier same as in the Scott tail wheel 3200 model bearings. I took the tail spring that was in fuselage out and built a shorter one with bearings inline with pivot on bottom of rudder. Epoxy in same hole as the tail spring I took out.

Tail wheel turns the rudder

Threaded bolt goes in up middle before tail wheel is installed into rudder and is titened in tension on bearings. Bearings are timken taper same as wheel bearings except smaller they need enough to take out play and no more so they will turn freely bolt is then tie wired.


Rudder has been made larger. . .

. . .and extended.


Balanced - You can see balance horn on front bottom I have melted buck shot in there for balancing rudder. They are 4130 tubs welded together and end plated welded and melted lead inside.

Rudder turns tail wheel.

Tail Wheel Bracket with the Tail Wheel removed.

Cushioning - You can see where axle goes through the rubber Donets there are four Donets off of where shock absorbers are installed on your car where they are bolted to frame and wheel so the axle does not contact bracket.

Four Rubber Donnets

Tail Wheel Bracket Width.

Rudder and fairing.

Fairing fiberglass

Wheel privets in line with rudder. This makes for very nice handling on ground.

It can take off and land in more cross wind. Larger rudder and better tail wheel control.

The pivot on top of rudder is the same as before I changed the bottom, I welded a aviation nut on bottom of 4130 Crome moly steel tube take out the Alunimun tube and bonded in steel tube so I can bolt rudder through bearings and attach where it privets.

Tail Wheel Bolt


Depth from axle back.

I added onto fuselage so it is 1.5" deeper where it meets rudder horn.

Bonded foam on bottom of fuselage sanded to shape and Fiberglassed with void for rudder horn.

Same bearings as in Scott 3200 tail wheel

I added to bottom of rudder

Pencil line where faring comes up to.

Tail Wheel Axle Out.
