Multiplex - Fun Cub

Work has been taking quite a bit of my time lately, so it's taken me a few month's to get my Fun Cub built.  This was another one of my birthday presents from back in August, and I just finished the plane up in the first week of January.  The build time can only be contributed to a lack of time contributed on my part.  The actual time spent working on the plane was only a few evenings.

For my setup I used the following:

  • Hobby King 40A ESC 4A UBEC
  • Turnigy Aerodrive SK3 - 3536-1050kv Brushless Outrunner Motor
  • ZIPPY Compact 2200mAh 3S 25C Lipo Pack
  • OrangeRx R800X Spektrum Compatible DSMX 8Ch 2.4Ghz TwinPort Rx
  • Prop is a 12x4
Build Tips
  1. After cutting out the flaps, pay attention to which is the left and which is the right.
  2. The Fun Cub should now come with a metal motor mount, if the one in the kit is plastic, get a metal one, this helps with vibration.
  3. User three screws per side of the metal motor mount.  You'll need to drill tiny tap holes above and below the center hole on both sides of the motor mount. 
  4. Use loctite or equivalent on the screws holding the motor to the motor mount
  5. Glue everything with lots of medium thickness CA, use kicker only where necessary. 
  6. Grab a building square and a friend to help you glue the tail feathers on straight.
So far haven't had the chance to fly it, but hopefully will get a chance this month.  Initial testing of the systems and a few taxi tests have peaked my interest in flying this plane...

Carbon Cub - Use the flap switch for the flaps Dx7s - DX8

On radios equipped with the three position flap switch, using it instead of the default gear switch is a nice improvement you can make when flying the Carbon Cub.  I struggled to figure out how to program this, and had to contact Horizon to get the exact instructions.  In my Carbon Cub post I did mention this, but here are the exact instructions.

Select wing type DUAL AILE / SINGLE FLAP  (the AUX1 channel is simply ignored by the receiver) (***Do Not! change the receiver programming to AUX1 for dual aile/flaperon). 

This will force the FLAP system to the GEAR channel. 
Then set the NORM position to -100% (yes, that minus 100%)
The MID position can be set to a position of your choosing for take off flaps

The LAND position can then be set to 100% … *** Do Not! exceed 100% (actually never do this on any linear servo)

Blade Nano Qx

For my birthday this year my wife bought me a few toys, one being the Blade Nano Qx.  This is one of the funnest ultra micros that I've flown.  It's a different flight experience from a helicopter or airplane, but it's very easy to fly as long as you leave the SAFE flight stabilization mode on.  If the light under the canopy goes red, watch out as your in agility mode.  Flips are possible in agility mode, but you will need some space unless you've got skills...
