Harrison Shull Project
Harrison Shull Project Modify Older Model Airborne Edge/Classic I grew weary of the crappy OEM nosewheel brake on my Airborne Edge/Classic trike. So I went in search
of some real stopping power to add to my trike. If I am going to have an experimental aircraft? then I
might as well experiment with it, eh?
After some online searching I found and ordered the Black Max brake kit from FBI
172577567Modified Master Cylinder I had Keith at FBI change the handle to a pedal so I could use it with my foot. Keith also custom fabbed a
super nice bracket that replaces the axle on my Airborne because the OEM axleis too short for the kit and has no woodruff key slot. Once I got all the parts in and did my research on how the process would go, I got started
This is the Black Max master cylinder with special pedal created by Keith at FBI along with the mounting
bracket I created to attach it to the round bar stock of the left footrest via SS pipe clamps.
172577571Removing OEM Axle Step 1: AKA the point of no return - CUT OFF YOUR AXLES leaving a ½? stub. Cut with oil slowly to keep temps down. Then file to smooth and flatten face at exactly ½?
172577568Mount the custom FBI Bracket Using bracket as guide, drill holes through axle tube and attach with supplied AN hardware. Then repeat
these steps on the other side. Once this is done, assemble the caliper and rotor assembly and slide it on axle.
Mount wheel/tire and you are rolling again!
172577569Bolt on the axle adapter This took maybe a couple of hours ? mostly because we were going slow and double checking everything to
make sure we got it right.
172577570Mounted MC And here it is mounted to my left footrest. The 90 degree fitting at the bottom allows the tubing to run
without a sharp kink in it. I am going to get some plastic pigtail tubing covers to put over the exposed tubing
at the front wheel hole in the pd to reduce the chances of debris flying in and hitting the tubing.
172577572Changed the tire Here is the Black Max kit tire (left) next to the well-worn OEM tire (right) from Airborne that I took off. It
is a lot smaller and quality-wise seems like a toy tire next to the OEM.
172577573Carlile Tire I ordered this Carlisle tire online to try and match the size and look of what I had originally on the trike
172577574Plumbing it up Then it was all about connecting the tubing and bleeding the lines. While I was there, I took the time to
install new bungees on the suspension too.
172577575Test time So now I have ?real? brakes on my older Airborne trike. I took the trike out for some taxi tests and was
pleasantly surprised. It stops very well. So well, in fact, that I even managed to ?bark? the rear tires with
some overzealous testing. After several laps up and down the runway checking the brakes at different
speeds and stopping distances, I went back to the hangar and checked everything in the system for tightness,
leaks, and overall soundness. Everything checked out so I took her out for a flight.
I shot a bunch of touch-and-goes and was able to stop easily within half the distance that I was getting with
my old brakes. I think that with some more flight time and experimentation, I can get the stopping distance
down to something super short ? maybe around 200 feet from touch down to full stop. I am excited to
measure this out.
All told, I spent about $625 on this kit and assorted added pieces to get decent brakes for my trike. It was a
fun project and has vastly improved the trike?s performance on short unimproved fields around here in
Appalachia. Feel free to shoot me any questions at [email protected]
