My Homemade Helicopter Starting Wand

My Homemade Helicopter Starting Wand (shaft)
Fits any rubber aircraft field starter (Hobbico, ect)

Bought a Mastercraft spade bit extension 12" approx
it had a quick release end that tapers on the one end
on the other was a torx that is the same width as any torx style removable screwdriver bit

I carefully filled the sides of that end to get beteen 5.5 to 6 torx size

The tapered end (quick realease end) fits and grabs the rubber perfectly on my 12v field starter

The Homemade wand fits inside the torx hole on my Webra .35 Nitro Perfectly!!

And It's outside I go in the morning to try my heli

The chuck end was not big enough
I added a stubby rubber philips screwdriver to the chuck end and it works ok
However my 12v starter is just to worn to crank the new webra long as it has great compression
So I need a new starter before i can break in the engine

KK v5.5 Right Angle Connector Modification

Frday my right angle 3 row (servo) connectors came in
I figured it was time to put them to use on my FC's, starting with the KK

So far its working out well...more to come when im finished

If I only had a solder sucker or some desoldering braid make the job quicker

Added Finished Pics

Lithium-Ion Polymer (LiPo)

Nominal Cell Voltage: 3.7V
Fully Charged Cell Voltage: 4.23V
Lowest Cell Discharge Voltage Before Damage: 3.0V

LIPO Capacity @ Voltage per cell (cell voltages, multiply by cell count for pack voltage, i.e. for 3S pack multiply x 3)

4.20v = 100%
4.03v = 76%
3.86v = 52%
3.83v = 42%
3.79v = 30%
3.70v = 11%
3.6?v = 0%

Capacity below 3.7V "resting" is not usable for flying, it's where the battery voltage dumps and damage begins.

11.0V-- 17% (3.67V per cell)

Radio Links

The Spektrum trainer port only gives either PPM-in or PPM-out, not both at the same time.
There's no power supply from the port and channels from the trainer can not be reassigned in a Tx menu.
Spektrum DX6i trainer: Inverted 6ch PPM, 3.0V idle, 0V active. 22ms fixed frame-length. 400us peaks. Signal width spans at least 930-1930us.
Insert trainer plug when Tx is off to output PPM (trainer).
Start the Tx first to input PPM (master).
When sending PPM to the Tx, at least 6 channels must be present (6-9 verified to work).
Frame length must be shorter than approx. 28ms.

Overseas Tracking

According to the regulations of UPU number rules, each number consists of 2 letters, 9 digits and the last 2 letters are standard ISO-3166 pointing to the origin of sender. Partial countries might have special number rules.

ĞRğ - Registered Mail (less than 2 kg)
ĞVğ - Registered Mail (Insured)(less than 2 kg)
ĞCğ - Ordinary Parcel (more than 2 kg)
ĞLğ - Airmail E-packet (less than 2 kg)
ĞEğ - Express Mail Service (EMS more than 2 kg)

Eg: RR123456789CN is a registered mail shipped by China Post.

•HongKong Post (tracking number starts with "RT" and ends with "HK" ,i.e:RT123456789HK)
•China Post Registered Airmail (tracking number starts with "R" and ends with "CN" ,i.e:RR123456789CN)

It is convention to put the letter/symbol for the multiplier/scale factor in place of the decimal point. This is to ensure clarity where schematics are copied and decimal points could be overlooked. So:

0R15 = 0.15 Ohm
4k7 = 4.7k, 4700 Ohms
6M8 = 6.8M, 6800000 Ohms
1V6 = 1.6V

E-OSD Conversion To an CL-OSD

Heres my E-OSD Conversion To an CL-OSD (E-OSD GPS)

Took a while to get my windows working right to program the flash
quite a bit of reading and asking questions here

Ive posted various precompiled configs here for NTSC and links to PAL ones too

It's turned out quite well for a $13.13 OSD from HobbyKing that now has support for gps, and many more functions after the flash and some soldering

Planning on using my EM406A Gps Module
That Features:
• 20-Channel Receiver
• Extremely high sensitivity : -159dBm
• 10m Positional Accuracy / 5m with WAAS
• Hot Start : 1s
• Warm Start : 38s
• Cold Start : 42s
• 70mA at 4.5-6.5V
• Outputs NMEA 0183 and SiRF binary protocol

• 30mm x 30mm x 10.5mm
• 16g including cable

Hoverthings HT-FPV Naze32 Swap to KK2.0

Finally figured I would give the KK2.0 a try
Everything came today packaged in a box from hobbyking

Removed wire harness for esc's
Added a Power distribution board

Mounted the KK

need to do something about the top plate as with the pins on the KK it wont attach ,they should be optional right angles available

possibly changing them to right angles if i cant get longer standoffs

Update ------> Finally Changed Standoffs

Can you Identify these mounts?

I have had these for sometime

World Models Anti Vibe Mount 1.2-1.4 FS
Anti Vibration mount for 1.20 - 1.40 4 stroke engines (Only for PL5911120).

looks as if the main motor mounts have been cut so they are separate now on mine

It's Getting Crowded In The Hobby Shanty

Recent pics of the hobby shanty
we use it to build & store rc gear and watch movies outside of the house
so far the projector has came down as the room has shrunk and we lost the wall space
going to need to build more storage lol

Receiver sizes??? why are some so big?
see pics

Easystar I - Build & Mods

Still deciding what mods and route to take with this

Added pics of progress....more to come

Also my 70mm edf motor conversion to an inrunner motor (using CA insta set can)
The diameter ended up being to much to fit the plane lo

I went with the stock 400 motor for now (attached by velcro)

SUNDAY UPDATE (March 24 2013)
Flew it today fies great, using the stock motor and a 3s 1800mah had to add two wieghts to the nose for GC
awesome landing too
Ordered these for it:...

XK2845-B-2000/17725 XK2845-B-2000kv Brushless Inrunner = $16.43
PA-4MM-6MM-A/19592 Propeller Adapter (Colet Type) 4mm = $1.88
MA5545/8006 Master Airscrew propeller 5.5x4.5 (2pc) = $2.62
not a bad price all together for some added power for the extra gear for fpv

Came in yesterday (April 3rd 2013)
the prop adapter was way to big on the shaft to fit the prop but I had another to use


Changed over to the brushless system (April 17th 2013)
pics added


Added covering to rudder (May 2nd 2013)
