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 8x5
  • 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.

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.

THe motors must be pointed exactly the same so I lined them up vertically using two straight edges then using a long straight edge I made sure the motor mounts were parallel

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!
