| A Twin! |
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.

Flight Gear
The following are some of my selected components with links to some of my favorite vendors.
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.
- Motor - Multistar 2209-980kv
- ESC - Blue Series 20A
- Prop - Graupner Cam Carbon E-Prop
- Battery - Multistar 4S/5200, 10C
|
Power Test
The results below are for a single motor using a flight pack for power.
|
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.
-
- w/Arduplane 3.4
RC Control
For radio gear I kept my standard DragonLink V2 system.
|
| Gear Deck |
OSD
For an OSD I kept the Micro MinimOSD from MT#2 which is reliable and easy to set-up with the APM.
-
- w/Firmware r800
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.
Airframe Build and Assembly
For this conversion I printed up some previously designed motor mounts.
|
| Simple Twin motor mount |
|
| Mounted up |
|
| Motor wiring under the wing |
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.
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.
Enjoy!
