Introduction

Decided to try the Mini Talon as a way to get a medium range plane I could easily throw in my car. I looked at the Twin Star and the Floater Jet but finally decided on the Mini Talon because my large Talon is such a great flyer and it is relativley inexpensive.

Airframe and Controls

I did decide to try a set of Digital servos mainly because I had them already. The linkage was changed to small Dubro 2-56 ball-ends on the Elevons because of the high miss-allignment btween the controll surface and the sevo arm travel.

For this build, I decided to try an RTFQ ReadyToFly 2.8 flight controller to save a few bucks and check out if they are reliable and as easy to set-up as my APM. I am using APMPlane 3.3 firmware.

For an OSD, I am running an RTFQ MicroMinium OSD with my own character set.

For radio gear I am using DragonLink V2 with the MicroRX Copter receiver.

Build/Layout

I won't spend anytime on pictures of assembling/gluing the foam bits together. I'll just show any mods and/or custom setups I did for this build. This starts with a simple layout with the Flight controller mounted on a plywood plate with rubber dampers attached between the wing support plates.

On the front I built an "FPV" module which includes the VTx, DL 1,3G Dipole antenna, a Storm32 brushless gimbal control board, an Effio camera, a three axis gimbal with Mobius camera and a two way camera switch.

To power the FPV module I printed a mount plate for a 12v regulator, a 5v regulator and an RMRC LC power filter. All three components are mounted on foam tape with wire ties to hold them down.

To install the VTx Dipole I had to design a simple 3D printed thumb wrench which would fit through the hole in the fuselage.
