Some Bixler 2 Upgrades

Bixler2FPV has done a pretty comprehensive job documenting his upgrades.  If you're upgrading a Bixler 2, check it out!








I think I'm going to reinforce the wings as he did:

And AJ Baker notes:

You have a couple of choices to enhance the strength of the wing spar.1. Drill (see 1a) out the spar hole and put in an 8mm CF.1a. To make a "drill", wrap and glue a piece of 80 (or60) grit sandpaper on the end of a 7/16" dowel rod and drill out the spar hole - takes about 30 seconds.1b. Install new 8mm CF spar with the old 6mm spar slid inside it.1c. OR - put 3-3mm CF tubes inside the new 8mm spar.2. Almost as good - Put a 4mm CF tube and a 3mm tube inside the existing 6mm stock tube.

Bixler 2 Power System Upgrade

Here are two options for upgrading the Power System on a Bixler 2 if you've got the motor mount extension.

This seems to be a popular setup that many people use.

• NTM Prop Drive 28-36 2200KV / 696W (USA Warehouse)
• HobbyKing Red Brick 30A ESC (US Warehouse)
• APC style propeller 8x4-E (USA Warehouse)
• NTM Prop Drive 28 Series Accessory Pack (USA Warehouse)

Here's one that even stronger... the 10 inch prop requires you to cut into the tail boom a bit.  Andreas and I are hoping that the extra power will be worth it when it's full up on FPV and autopilot gear.

• NTM Prop Drive Series 35-30 1100kv / 380w (USA Warehouse)
• TURNIGY TRUST 45A SBEC Brushless Speed Controller (USA Warehouse)
• NTM Prop Drive 35 Series Accessory Pack (USA Warehouse)
• Genuine APC props: 10x4.8 if memory serves

(note: this motor has a limit of 32 amps, and as configured it hits 30 amps on the bench... be forewarned!)

BTW, regarding servos... you need 6 if you do the flaps.  I'm pleased with these.  If your radio can handle the mixing, you can use two channels for the flaps.  Otherwise, get a servo reverser.

• HXT900 9g / 1.6kg / .12sec Micro Servo (USA Warehouse)
• Turnigy Servo Signal Reverser (USA Warehouse)

Two Bixler 2 Extended Motor Mounts

Here's the Small Parts motor mount extension I got for the Bixler 2.  It's rated for up to 9 inch prop, but following Andreas' lead I trimmed a notch in the Bixler tail and fit a 10 x 4.7.  It draws 30 amps off a 3S battery.

HK now has a similar mount... no idea how it works, but it's certainly a bit cheaper.
