==<br> Introduction - Mini Talon Number 3 ==

Not so much a "build" but rather a rebuild and conversion. Mini Talon #2 unfortunately was nearly destroyed due to an ESC failure so I decided to repair it and convert it to a twin motor unit using my recently designed twin motor mounts.<br><br>

== General Specifications  ==

== Flight Gear ==

The following are some of my selected components with links to some of my favorite vendors.<br><br>

==== Power Set-up ====

For power on this build I have chosen the Multistar 2209-980kv motors. For ESC's, I am using two HobbyKing Blue Series 20A with extra Low ESR capacitors added.<br><br>

:* Motor - Multistar 2209-980kv
:* ESC - Blue Series 20A
:* Prop - Graupner Cam Carbon E-Prop
:* Battery - Multistar 4S/5200, 10C<br><br>

'''Power Test'''<br>

The results below are for a single motor using a flight pack for power.<br>

<br><br>

==== Flight Control ====

For flight control I used the same APM 2.8 already installed from MT#2. It is very inexpensive and in my experience completely reliable.<br><br>

:: w/Arduplane 3.4
<br>

'''RC Control'''<br>

For radio gear I kept my standard DragonLink V2 system.<br><br>

<br><br>

'''OSD'''<br>

For an OSD I kept the Micro MinimOSD from MT#2 which is reliable and easy to set-up with the APM.<br><br>

:: w/Firmware r800
<br><br>

==== Video Downlink====

For the video downlink I kept the RMRC 400mw 1.2/1.3G VTx with a DragonLink video dipole. For an FPV camera I kept the HS1184 from MT #2.
<br><br>

== Airframe Build and Assembly ==

For this conversion I printed up some previously designed motor mounts.<br>

==== Gear Deck ====

The Gear deck was pretty much unchanged from MT#2 with the exception of adding the two 20A ESC's underneath.

=== Ruddervators and Wings ===

Nothing new or special here. I kept them unchanged from MT#2.<br><br>

== Maiden Video! ==

The maiden of the Twin Mini Talon #3 was, well, iffy! It was a beautiful 78 degree morning in Spring Canyon and wind was near zero. After a very crazy/scary launch everything worked as I'd hoped and I was pleasantly surprised at the amount of power out of these two tiny motors. Next will be some longer range shake-down flights.<br><br>

Enjoy!<br>
