Tony -

I thought that torque demanding, high speed, discomposing, prayer shattering lift off - was part of the prelim testing.

WIRLYBIRD,

Thank you! If the builder installs the turbine backwards, I'll just fly it backwards

It will be my camera ship so being able to see it is a must. But then again, once I install all the goodies on there, I could literally go 1000 feet without the need to even see it

Greg,
I have spent the last 22 years working on nuclear capable weapons!
That explains everything! BTW, do you still have that 'twitch' every so often?

I knew you were kidding on the paint! My exact words to Jacko's, "Please paint it exactly same as Greg's canopy other than no white paint for the break and lower the color transition." I'm going to ask him to paint more canopies for me Please show me your other canopies so I could copy.

Chris,
Wiring is one of my pet peeves as well and, like you, I usually spend more time getting it "just the way I want it." The wire sleeving you used is also available from an outfit called CableOrganizer.com (http://www.cableorganizer.com). You can get it in varying grades depending on how much chaffe and heat resistability you need.

While waiting for a custom part for Dakine's bird, I built up Tree's engine. (Didn't want you to think we forgot about you in all the excitement!!)

I'll bench run it tommorrow, and if all goes well, it'll ship on Tuesday. (Mon is MLK day)

Tree's engine is test run, setup, ready to ship on Tuesday!!

Also got Dakine's servos centered and servo wheels and control balls installed. Centering the servos and wheels is very important for a well trimmed heli.

Start in the radio, ensuring all subtrims are zeroed, travels are equal on both sides. Also center the pitch curves, 0 at bottom of stick, 50% at midstick, and 100% at top of stick. Verify it by looking at the pitch curve. It should be a straight line from 0 to 100%. Futaba has the knobs or sliders turned on to affect the pitch and throttle curves, so these either need to be turned off, or verified that they are in the middle.

Now center all mechanical trims on the radio, and center the pitch/throttle stick. Power up the radio and the helicopter, and all of your servos should be perfectly centered.

To center the servo wheels, place a wheel onto the output shaft checking to see if one of the lines on the servos lines up with the servo perfectly. If not, remove it, rotate, reinstall and check again. Of course, do this while the radio and heli are powered up. Now you can locate and drill the holes for the control balls.

Tree, I'm sorry. I told you a story. Your Turbine kit will not go out tommorrow. UPS was working today so it went out today instead!!

All linkages are installed on Dakine's Turbine, ball links are reamed for smooth, easy movement.

Finished up the rear gas plumbing and wiring as well.

You ain't seen nuthin, yet!

But, we're getting ahead of ourselves!!

After we get the wiring the way we want, then the tank saddles can be installed.

The hole in the top of the tank saddle is perfect for locating the fuel lines in!! I designed it that way, Honest!!

The slots in the frames are used to attach the tanks with Heavy Duty Tye Wraps, or alternatively, Velcro can be used.

The tanks are attached and plumbing finished up. Both tanks feed into a "T" fitting, then to the UAT bubble trap, to the fuel pump at the front of the heli. The tubing and fittings at the rear of the tanks are the vents. Don't plug these, and if you do, REMOVE the plugs before flying!! (Greg)

Speaking of Greg, now's a good time for another video. Most have probably seen this already, but it shows some of the capabilities of this bird. Fully aerobatic, not just some stall turns and a few pirouettes, ALL the way upside down inverted, loops, rolls, and power to spare with the Wren 2 stage system!

Tail boom installed, boom supports and tail pushrod, also.

When installing the boom, push it all the way in until the dogbone on the arrow shaft fully engages the delrin coupler in the mechanics. THEN pull the boom back OUT 1 mm. This prevents a constant rearward pressure on the tail drive system, pushing against your tail gear mesh, tightening it up more than you want.

This bird is LOOONNGG, 810mm V-Blades included in the kit, installed. Canopy in place. She looks GOOOD!

For the test flights, I'll remove the nice painted canopy and tail fins, just in case!! I haven't crashed one in test flights yet, but you never know what may happen.....

Hey Chris, why break the tradition now?

She's looking good!

Are you sure you want to take off the boom before you ship it to me? Knowing me, I'd manage to screw up the gear mesh instructions.

Let's see that was.....push it all the way in until the dogbone on the arrow shaft fully engages the delrin coupler in the mechanics. THEN pull the boom back OUT 1 mm.

Chris, perhaps you could mark the boom where I should pull it back out, the way it is now. This would be idiot proof for an idiot like me. Thanks
