The final install, just need shrink on the servo plugs. I am going to go wild on a scheme with vibrant colours
next, but for now I am going to do the UN version as I need No paint to do it so I can get flying fast!
I use "Tesla tape" for the borders following with 3/4" high quality masking tape. I use scotch brite on the exposed
window frames and white gel coat. I didnt need any filler on the nose! I just use a curved exacto blade to shave off
spine on the seam.

A few coats of flat black paint and we are done! I added the wipers (with some mods) and you can see the borders on the
glazing as well.

The quick cockpit! ( I wont see it anyway how fast I will be flying! ) agood shot of the gel coat finsish...paint optional!

Added heat vent. (just because I wanted to.)

And there she is ! 1-2 pounds lighter due to no paint and total time finish this scheme?
2 hours! Now instead of weeks of prep and painting and I can be flying a scale Jet in
record time! (If I did not have to document all of this it would have only taken me about
2 weeks out of the box to get to the field! )Stay tuned for flight vids and pics!
After 230 pictures I need a rest! : )

For our customers using the MC-24 Please call, we can fax you
the instructions for the throttle set-up. 352-371-3132 .Futaba 9 Z throttle setup / by Don DesandreThis is the quick and easy way to set up The 9Z for the throttle on the Graupner PHT-3 system.
Plug your throttle lead into channel 7 of the RX.From the functions menu (FNC) of the 9Z select Channel 7,
then select control (CTL) and scroll across the bottom and select the left slider (LS)Confirm the change you
have made by going to the servo graph (SRV) You want to make sure that slider is operating in the correct
direction pushing up on the slider should increase the function.If it does not reverse the channel. Now go back
to the FNC menu and move the T-2 throttle trim to channel 7 (AUX1) From the main screen select TRM,
go to T-2 and increase the rates to 50 and 100 percent on the first and second steps. This will make you trim
very fast acting, almost like a manual trim lever.From the ATV menu select NXT and set your servo delay to
5 seconds for AUX 1.
Your now ready to teach the ECU.Pitch curves:
Please see instructions for pitch curve settings, we have found that those suggested numbers work best.
Also the tail rotor works perfectly first time if adjusted according to the instructions.Servo lengths:
I found that the cyclic servo arm length, from center of servo horn screw to ball center is best at 18 mm, this
produces the "Cadillac" feel with plenty of spunk! I tried 21 and thought is was a bit quick for a heli of this size.
Fail Safes:
If you are useing the PCM or SPCM modulations, then you need to rely on your radio's fail safe system,
and not the ECU, The ECU's fail safe system is best used with FM recievers. If you use the ECU fail safe you must
program your radio's fail safe accordingly outside the limits of normal stick opertaion eg:120%, so that is there is no
chance of conflicts between the two systems.Most will opt to their radio's system, the throttle channel should be
programmed to go to idle on your radio. Using the GSU check to see in the "limits menu" that there is a one second
delay, that the idle goes to 33k rpm and the timeout setting is 20 seconds.(the 20 seconds is assuming after a loss of
control the heli is down by that point and the turbine need not be running)Gyro:
I found the suggested setting a good start, about 50% gain to start. I used the 401 gyro by Futaba so this needed an extra
channel to work at all! I was'nt too thrilled about that, I hooked my lights to my gear (JR match box) and went on. You have
start that gyro in heading hold mode, with a swtich, that portion set to over 50%. anything over 50% is heading hold.
Then you can swtich back to normal after start-up of radio. I though this too was a bit of trouble,I like things simple.
The performance is excellent though and I am very happy with the system overall. I knocked the atv's down on the rudder
channel to slow the tail al little , about 75% setting works well for me, firm but quick enough if need be.
This was tested and flown to our tastes, your flying styles and tastes may differ, so you mqay end up with slightly different
numbers in your adjustments. Please feel free to contact us with addtional questions.

ADMENDUM FOR NH-90 JET
By: Zach de la Torre
4 Servo CCPM 10X programming stepsStep #1. In code 65 select the 1 servo swash plate mix.
Note: Steps 2 thru 4 are needed to synchronize the servo throw and to prevent over travel. Initial setup values are given below. During final setup and adjustments the pitch curves (code 68) and dual rates (code 13) will be used to achieve the desired pitch, aileron and elevator travel (do not use travel adjust).
Step #2. Code 12 travel adjust- Increase the aileron, elevator and pitch travel adjustments to 150% in each direction.
(YOU MUST ALSO INCRESE AUX.2 TO 150% IN EACH DIRECTION TO OBTAIN LINEAR SERVO TRAVEL FOR ALL 4 SERVO’SStep #3. Code 13 dual rate- adjust the dual rate values for aileron and elevator to 50% in all dual rate positions (0, 1,2).
Step #4. Code 68 pitch curve- Reduce the high pitch setting to 75% and the low pitch setting to 25% in all flight modes (0, 1,2, H).
Step #5. Code 51 mix 1- Mix pitch to aileron at 100% in each direction
Step #6. Code 52 mix 2- Mix aileron to pitch at 100% in each direction an turn on the trim.
Step #7. Code 53 mix 3- Mix pitch to elevator at 100% in each direction.
ONCE YOU HAVE SET THE VALUES TO +100% IN THIS STEP, YOU WILL NEED TO PRESS THE TURN BUTTON ON THE SCREEN TO GET –100% IN ORDER FOR THE PITCH TO TRAVEL CORRECTLYStep #8. Code 54 mix 4- Mix elevator to aux 2 at 100% in each direction and turn on the trim.
Step #9. Code 55 mix 5- Mix Pitch to Aux 2 at 100% in each direction.
NOTE: YOU WILL HAVE REVERSE CHANNEL 3 (ELEVATOR) IN ORDER TO GET THE ELEVATOR SERVO’S TO MOVE IN OPPOSITE DIRECTIONS.
Servo assignment
Forward servo- elevator
Rearward servo- Aux. 2
Right servo – Aileron
Left aileron- Aux. 1
