After crashing my TwinStar last spring I took a bit of a break from FPV. I considered selling all my equipment and moving on, but I ended up keeping it all. Good thing too! It took a couple months but I got my excitement back. After doing a bunch of research I decided to get the quintessential FPV plane: the Skywalker. It doesn't look as good as the TwinStar, but it sure can haul a lot more and only has one motor, so if the ESC burns out (one of mine did on the TS; this caused the crash) you don't get thrown into the ground.

I don't have any pictures from the build, but it went very smoothly. It took me about a week to put together, working for around 4 hours each day. I wanted to be methodical and give the plane some needed upgrades. The equipment:
  • Receiver: Futaba R319DPS receiver (72 MHz). Using all 9 channels.
  • Servos: 4x HS-82MG in wings; 2x HS-65 HB in the tail. The HS-82's have a tendency to whir quite a bit when they're on. Mildly irritating when it's on the ground.
  • Motor: Emax 2820/07; 920 kv; 153 grams (http://www.headsuprc.com/servlet/the...ushless/Detail)
  • Prop: Any of the following will work: 9x6, 10x5, 10x6, 10x7. Right now I have a 10x6. The 9x6 lacks the thrust of the 10" props.
  • ESC: Hobbywing Platinum 40A
  • Flight Battery: Sky Lipo 4S 4000 mAh
  • BEC: CastleCreations 10A
  • Gyro: GWS PG-02 dual-gain, switchable via Tx
  • FPV weight: about 73 oz.
FPV stuff:
  • Video battery: small 3S
  • Flight cam: RMRC 480
  • VTX: 400 mW Sunsky
  • VTX antena: DIY

It's been a while since I've posted anything here, so here's my latest video. It's a compilation of the best clips from this past year. Enjoy!

I flew on the stock Radian setup (aside from my paint job) for about 6 months before I had any problems. But when I had a problem, I had a big one. One of the pins that holds the prop blades in sheared out of the plastic spinner, throwing the prop blade. This occurred at full throttle and the single blade that remained proceeded to tear the firewall out of the foam.

After getting a replacement fuse from HH I discovered that the new prop developed almost no power. At full throttle, I could hardly climb. I knew something was wrong and traced the problem to flexible prop blades.

At this point, I decided to upgrade the nose once and for all so I wouldn't have any further problems. Another user pointed out that the Multiplex glider spinner for the Cularis / Easyglider (Part no. M733500) fits perfectly on the nose of the Radian. I added some Graupner 11x6 blades and I was back in business for about $30.

The performance increase is noticeable: vertical takeoffs are possible and I can climb vertically even with a camera on board. The entire assembly is very sturdy. I like the look of the new spinner too.

I highly recommend this mod for any and all Radians.

My latest plane is a Multiplex TwinStar II that will be a platform for FPV. Specs:

Receiver: Futaba R319DPS receiver (72 MHz)
Servos: HS-82MG (tail servos moved to tail boom from nose)
Motors: eRC 900kv outrunners from Hobby Lobby (http://www.hobby-lobby.com/480_size_...33023_prd1.htm)
Props: APC 8x6 Counter-rotating; APC 9x6 CR; GWS 9x7.5 normal-rotating (different props for different scenarios)
ESCs: 18A Castle Thunderbirds
Battery: 3S one or more
Gyro: GWS PG-02 dual-gain, switchable via Tx
AUW (empty): 33oz.
AUW (2 2200 mAh): 44oz.
FPV weight (1 2200 mAh): around 50 oz.

I made a conscious decision to put quality components in this aircraft. I have purchased from a particular low-cost vendor before and was thoroughly disappointed in its service. This plane is an FPV platform and I won't take chances that one of my ESCs will just quit (see note at bottom), or that the batteries will pop while I'm in the air, or the servos will strip if I bump the control surfaces transporting it.

I did a number of mods including moving the tail servos, shaving the motor mounts to clear the motors, cutting a lot of foam out of the nose for more space, and cutting the hatch you can see in the third picture.

The paint job was designed in Inkscape and done with Krylon Fusion spray paint. I used a similar method as when I painted my Radian
1. Prep the foam for painting by cleaning with denatured alcohol and lightly sanding to get rid of the mold bumps.
2. Mask off paint sections. I used...Continue Reading

After browsing through the Radian thread, I found a beautiful paint job by StudioRS (details on his blog ). I took much inspiration from his design but also added a few flairs of my own. The main wing is painted and everything else is vinyl from the local FastSigns.

Steps to painting the wings:
-Give wings a couple of baths in denatured alcohol to clean off all of the mold release. I used a sponge with a scrubbing side to really work the alcohol in.
-Sand
-Mask off the leading/trailing edges and the edge on the upper side
-Apply 3 coats of Krylon Short Cuts
-Apply 3 coats of Minwax Polycrylic

The decals were designed in Inkscape, printed on paper, taped to the vinyl, and cut with an XActo knife. For application, I spread water with a couple of drops of dish soap on the wings so I could get the positioning perfect. Squeegee out the water with a credit card and dry....Continue Reading
