New DL procedures for calibration and binding

Notes from Mike (DL);
-DL receiver's blue LED intermittently flashing is OK. Here's Mike's explanation regarding this.
-Procedure to verify if firmware update was successful.

Dragon Link Binding Steps

In this section, we will bind the RX to the TX. This process programs the RX so that it knows the ID of the TX it is intended to work with.
The following steps will bind the DragonLink TX and RX:
1. Start with both the DragonLink TX and RX powered off.
2. Press and hold the bind/menu button on the DragonLink TX.
3. While holding the button, turn the DragonLink TX on.
4. Wait at least 5 seconds, or until the LED turns YELLOW and then release the button.
5. The DragonLink’s LED should now be flashing YELLOW. If it isn’t, restart the process from step 1.
6. Power on the DragonLink RX.
7. The DragonLink RX’s “status” LED will come on.
8. Power cycle the DragonLink TX.
9. As soon as the DragonLink TX comes on, the DragonLink RX’s “status” LED should go dark.
10. Power cycle the DragonLink RX.
After power cycling the DragonLink pair, you should have RC control over the receiver. This can be tested by putting a servo on channel 1 of the DragonLink RX. On most RC transmitters, this will map to the throttle stick, which can be moved up and down to set the servo’s position.

I replaced the flight controller from the mQX to 180QX and, now, I converted it into a miniFPV. Let me tell ya, it's one heck of an FPV flyer. It is so much fun to fly.
Here's what you need to turn this into FPV:
-600TVL 120degree Wide Angle Super Mini FPV Camera with MIC
-ATU 5.8GHZ 200MW + CL SET
-Dip Switch (optional) from ebay

I just discovered this not too long ago and decided to order after reading all the rave reviews. All of them are true. The mQX is so much fun to fly. It's more fun to fly than the mSR. After a few flights, I have managed to crash it a lot of times and the little booger keeps on ticking - very durable... So far, I have been really impressed with it.

Here's my latest scratch-built, the Slapped-Together EP-SALG Version 6.0. I had to finally retire Version 4.0 (this photo was taken when she was still young ) as she was getting beat up although she was still flying well. I needed to build a new one since we're about to take another long road trip to Big D (Dallas, Tx)... I had built Slapped Together SALG Vesion 3.0 for our road trip to Dallas in 2008, it was converted to electric-powered (Version 4.0) after returning home from the road trip.

One nice feature about Version 6.0 is that the wing is removable for portability. The wing is held with only two rubber bands. Version 6.0 has had her maiden flight and she flies extremely well. I'm very happy the way this one turned out.

For those interested, the previous versions can be viewed here.

Materials of Construction

-Bluecore foam for the pod area, nose area is reinforced with carbon fiber strips and 3/4oz fiberglass
-Carbon fiber tube for the tail boom
-3mm depron foam
-9mm depron foam sanded to a flat-bottm airfoil


Receiver: AR6100
ESC: TURNIGY Plush 6A /.8bec/6g Speed Controller
Servos: 3g

My cousin gave me my first warbird plane for all the hard work and effort I put in building his Corsair, which was a really nice surprise since I wasn't expecting anything in return. It is a very nice-looking plane and the only model that will be stored inside the house on top of the entertainment center.

The build was a snap, nothing had to be glued. I had to widen the servo wells a bit to fit the Hitec HS-55 servos; and I just pushed them in the wells for a snug, tight fit... What the took the longest was programming the Eflite ESC since it needed to be programmed to handle to 2cell lipos... The ESC programming was the typical that you have to listen to the tones, which I don't like because it gets confusing when you're listening to the tones to get to the option that needed changing.

The only mod I did to this plane was I had to cut out the inside part of the canopy in order to fit the batteries that I was using with it. The lipo batteries used are Thunderpower 910mah, Eflite 800mah, and Moxie 500mah.

She's already been maiden... She flies well and very fast. This plane is definitely not for beginners...

Well, I believe I've caught the heli-bug. The UPS man delivered my Blade MSR yesterday... I'll tell you, it is so much fun and sooo easy to fly once you get it setup correctly. After going through several forums on what is the optimal DX7 setup for the Blade MSR, I found the attached pdf file of the DX7 settings for Blade MSR (from helifreak forum) to be the most easy to follow and the settings make the Blade MSR to fly very docile because without it, the Blade MSR can be a handful to fly... I actually bound it with my DX7 straight out of the box, attempted to fly it and , boy, it was definitely a handful to fly..

Background: I bought a CX2 a while back ago, I believe it was in 2008 when I purchased it at a local hobby shop, and I flew it a few times then my heli interest kind of just went away after a while. Recently, a co-worker of mine showed me a Blade MCX and after seeing this little booger fly, it rekindled my interest... In fact, I was going to sell my Blade CX2 to this co-worker... Well, needless to say, I kept the darn CX2 and started playing with it again; thus, starting a blog on it to capture information about setups and hop-ups.

Since the Blade MSR, I've assimilated myself in anything that is micro heli... A friend introduced me to the Syma S107, a really inexpensive toy micro heli. For 20 bucks plus shipping, you can't beat it, so I ordered one. I hope she performs as expected since everyone who has one has said that it flies well.

The S107 came in the mail this past Memorial Day weekend and like everyone has said she flies and performs very well... Excellent buy for only 20 bucks...

Finally, a site on how I can use the LP5DSM (transmitter that came with the Blade CX2) as a buddy box....

Connecting to a transmitter to a DX7
DX7 with DX6 Buddy Box
How to buddy box an LP5DSM
How to Buddy Box Dx6i (Master) and LP5DSM (Slave) (4 min 56 sec)
(4 min 56 sec)

In "P-LINK" mode, any simple non-programmable 4 channel slave TX with the same channel assignment (JR) can be connected to the master DX7. The master DX7 will take care of all throws and all mixings and settings. Very easy ! This is really the ideal program for easy buddy boxing, without hasstle. And the buddy lead is a simple mono to mono jack 1/8".

Steps to connect a 4-channel transmitter to the DX7 transmitter (master):
1. On the DX7, hold the Scroll Down and Select buttons (left of the screen) simultaneously. This brings up the System Setup Mode.

2. In the System Setup Mode, use the Scroll Up and Down buttons to get to the [MODEL SELECT] screen. In this screen, using the Increase and Decrease buttons (right of the screen) to select the model that will be used for training.

3. Once the model is selected, use the Scroll Up and Down buttons to get to the [TRAINER] screen. In this screen, using the Increase and Decrease buttons to select P-LINK mode. Also, this allows you to choose which rocker switch to be used.

4. Turn off the DX7 then turn it back on.

5. On the DX7 screen, the following are displayed: under the selected Model number "NO TRAINEE" text flashes and the DX7 beeps periodically.

6. Using the buddy cord, connect the 4-channel transmitter (it must be turned on before connecting) to the DX7.

7. After connecting, the screen displays "P-LINK" and below it, it reads SPEKTRUM DX7.
