I'm looking for an alternative to Hobbyking for things like LiPos, etc.
Any suggestions?

May 19 2014 - "Thanks for shopping at our store"
May 21 - "Your parcel has been sent from the HobbyKing.com warehouse!"
June?
July 10, 2014 - Nothing yet. The tracking number has been received and that's it.

50 days later, still no package.

Sooooo happy to be flying in the sunshine a bit. Such a long winter..
This is Halifax Harbour this week.

Burnside NS, a commercial/industrial area serving Halifax, Dartmouth and places beyond. Soon to be gentrified with expensive waterfront condos. Yay?

Someday the signs will read "No FPV" instead of "No Skateboarding"

I see the 1986 Disney movie "The Flight of The Navigator" as an inception movie.

To me it places the idea of one boy and one machine together exploring at high speed our countryside and roads. It suggests that a young boy knows better than the established authority and he takes his machine to places that tickle his imagination instead of the old-school view of air travel. He enjoys himself at the cost of stress to the establishment.

One generation later we have that generation of children advancing the way for FPV, UAS and general robotic aviation. Yea right, The Matrix isn't real. Get real.

Use imagination to inspire a generation of robotic/fpv enthusiasts. Nobody is going to jail for FPV...Disney has told us to for 25+ years.

Here's Halifax Jeff getting some practice in on his homebuilt Tri last night in the winds. Good job Jeff.

Was out bombing around the neighborhood yesterday by the harbour at Shannon Park in Dartmouth. Out of a few hundred exposures I found a couple that are OK. The Cold War era military housing was a treat with it's abandoned playground.

pic1- Gazing south towards the "New Bridge", Tuft's Cove generating plant and a Dartmouth neighborhood along Windmill Road.

pic2- Shannon Park is an abandoned Cold War era military housing complex. It occupies some of the nicest untouched harbour shorelines and will someday be dug up for very very expensive condos.

pic3- Rusty abandoned playground in the middle of the buildings.

This is a crop of interest from doing some runs in Beaverbank, NS.
One of the neighbors who shares what his garden produces wanted an overhead shot. No problem.

Went out to the Darkside to demo a dusk flight. Went out about 1.2km downwind to reach some wilderness. The whole area is abandoned or industrial so there's lots to look at.

FPV'ing at night in a snowstorm in Nova Scotia. Turned around at one mile because the snow was getting heavy but broke up the air-frame on the way home. Oops for playing. OSD was snaking in the 30+ km/h winds for a while but you can see the gain change in the vid..
Everything found it's way home by the next day. 1130pm, Feb 6 2013.

Your first groundstation, no excuses.
$2 of pink foam and packing tape to protect hundreds of dollars of kit.

One of the first major projects many apprentices take on is the building of their own workbench. Whether it is for wood working or metal working it's the first step towards a commitment to learning and doing the basics properly. It's a foundation. The same can be said for the beginner FPV'er and their first ground station.

The ground station is the foundation to build on and it's the first thing many onlookers will inspect when they walk up to you at the field to see what you're doing. It testifies to many symbolic things about your professionalism but its first priority is to protect that precious kit of yours. Respect your equipment, give it a good home and it will reward you with a much longer service life.

This easy to build groundstation is one of the first things a new FPVer should acquire to help protect and keep their kit neatly stored for transport to and from the flying field. It also makes for easy set up at home for bench testing various airframe and equipment changes. No wire hassles and no stress when it's time to fly. No tripod is needed either as it's designed to slip over a simple broomstick pushed into the ground or snow.

Constructed of hot glue and 1/2 pink foam which can be sourced nearly anywhere it costs virtually nothing but protects everything. After gluing you may paint or decorate as you see fit before covering in clear...Continue Reading

I've been doing GIS work with my planes for quite a while now and I have yet to share any of my mosaics or the like.

Here is one of the first photos I was happy with from a while back. A sub 1m resolution of ma' house.

Skew Planar Wheel dimensions as calculated at http://www.ve3byt.com/SkewPlanarAntenna/

31,329/f (Mhz) = element length

1,080 Mhz = 290.1mm
1,120 Mhz = 279.7mm
1,160 Mhz = 270.0mm
1,200 Mhz = 261.1mm
1,240 Mhz = 252.7mm
1,280 Mhz = 244.5mm

Skew Planar Wheel dimensions as calculated by Alex Greve (IBCrazy) at the RCG thread: SPW Tutorial Thread

1,080 Mhz = 278.4mm
1,120 Mhz = 268.5mm
1,160 Mhz = 259.2mm
1,200 Mhz = 250.6mm
1,240 Mhz = 242.5mm
1,280 Mhz = 234.9mm

construction:
.030-.045 mig welder wire is great

Hey guys;
I fly in a lot of places around Halifax, Dartmouth, Lower Sackville and Bedford and I was wondering where the other pilots around here are.

Check in by responding below or private message (to me) if you are stealthy about your FPVing adventures.

I fly a 66" Skywalker-looking plane and a 66" flying wing if anybody wants to play.

One thing I find works pretty well for fixing (video) interference is a simple coaxial cable band reject filter on the LRS transmitter. It's pretty easy:

Take a section of coaxial cable 1/4 wavelength long (accounting for velocity factor)and splice it into the feed of your LRS antenna. Leave the end of the cable open!

For example: if filtering 1280MHz from your LRS using RG316 cable, The calculation would go like this:

Vf = .7
f = 1280
Vf*2933/f = length in inches

.7 *2933/1280 = 1.603"

Done!

No more 1280 MHz trouble from your LRS. This also works to keep your buddy's 1280MHz video out of your 2.4GHz video system when flying in close

How it works:
A 1/4 wavelength section of coaxial cable is an impedance transformer. It follows the formula Zin = Z0^2/Zl

Zin = input impedance of the filter
Z0 = impedance of the coaxial cable
Zl = load impeance

An open circuit at the end of the cable means Zl = infinity since the impeance of an open circuit is infinite (for our purposes anyway)

Doing the math, you get 2500/infinity = 0 Thus an open circuit at the end of the cable looks like a short to your 1280MHz harmonic but is still an open circuit for your 433 control!
