Another plane! Decided to try something "Bix" like for a change. Really like the plastic fuse and the kit components. Kit quality is quite good too.

Here is more information on my build-

This is my version of a super fun project found here on RCGroups by poster cyborgcnc. It works exceptionally well balancing both motors and props (and both together). Here is a link to cyborgcnc's project pages:

RCGroups - Dynamic Propeller Balancer Build

This link is to my Wiki write-up on how I did this project.

This project is really an extension of my earlier Forward Offset Pan & Tilt and my recent Lightweight Pan and Tilt. The Lightweight P&T used printed gears and this unit uses "Store Bought" Acetyl gears which (for me) work much more smoothly. Built to the below specs, it will turn 390 degrees and tilt 110 degrees total. It is designed around the Turnigy™ TGY-R5180MG 180 Degree Metal Gear Analog Servo and a pair of 32 pitch Acetyl gears from ServoCity. It is a bit more robust and with the new gears much smoother. It will cover the entire 390 degree sweep with standard servo output of 1000µs to 2000µs and centers very well.

So, here is my 390 degree Pan & Tilt

390 degrees rotation and light weight!

Another wing! At 1200mm this one slots in nicely between the Wingwing Z84 and the Zeta FX-61. It is a great small flyer easily thrown into the car or onto a backpack and at 895g AUW seems like it will glide forever!

After buying and building several Pan and Tilt set-ups I got tired of how cheaply the purchased ones were and how flimsy most were. The biggest problem has always been the pan axis is simply never robust enough. When I did find something that was strong enough (for me) it was always too heavy, too expensive, to complicated with gears or belts or presented too much wind area.

So, here is my Heavy Duty Pan & Tilt

Build Wiki

385 degrees rotation is just enough!

Another number 2 . On this second Mini Talon build I have designed a 3D print "Kit" which helps keep things organized and aerodynamic. Like the Number 2 FX-61 I have really put the 3D printer to work and come away with what looks to be a very nice plane in all respects. Check it out here:

On this second FX-61 build I have decided to go lighter and swoopier (smoother). I have really put the Maker Select 3D printer to work on this project and still managed to keep it to 1613g AUW even with the 32 PLA prints used in the build!

Here is the link to my build pages and print files on this project:

Here is a short article on what I call the "Mel Method" after learning this from RCGroups poster Melsailsnorth. Basically it is a method of bonding Kevlar fabric to an EPO or EPP foam plane using thin CA for the purpose of creating a skid plate or wing joiner that is darn near indestructible.

I've been asked a lot about how I have setup a folding prop in my pusher planes so here is a picture and a link to my Wiki page on this.

For those that really want to fly long distance, round cells could be in your future

So I got one set of three of the Panasonic 18650PF round cells, soldered them up and ran a pile of tests. I then built a 3S3P pack and you can see the build here:

Ready to wrap!

Pack complete and flight test successful! (see the Wiki for more information)

After many flights with the PopWing sorting out my gear I decided to step up to something a little larger and certainly more robust.

I can't stop changing this rock star performer! I've added a Tarot GoPro3 camera holder to make the Gimbal much more rigid and compact.

I've wanted an FPV wing ever since seeing my first Team Blacksheep videos. Well CommonSenseRC had a sale on 51" PopWings so I jumped in!

The set-up article linked below is a How-To for the Martinez/BruGi controllers. It includes information and code sources to be successful in getting this controller running smooth. (It does not include any information about using a nulled or hacked Alexmos firmware on these boards.)
