glad your getting her tuned up
I use a lazy susan to check out my tails before trying to fly them LOL
if you do this you can set up the tail easy but remember to take main blades off

Not quite sure how that works, Phil.
Don't you need the blades attached to create the torque needed to be counteracted by the tail? No blades...no torque.

Thanks Sol, back to square one.

Just to save you some search time...

Better mic your balls just to make sure of the 4.7mm sizing.

I think Helidirect has the linkage balls for your 450. Ron I just made one, and you should consider a set of training gear the bigger the better it will protect all the parts until you get this setup and use to it.. Ray

[akphill]

Sol your just setting up the tail
you don't need blades for that just the ones on the tail
you can setup your gyro also give it a try see what happens

[ronp]

Thanks guys very disappointed, thought I was going in the correct direction and this on the ground crash really sucks.
Thanks Sol I found the Balls on EBAY from a US seller.
For the time being can I use a cheaper servo for the tail until I replace the one that blew apart?
Another thing I didn't understand what Sol and Phil were discussing regarding the tail set up??ron

[Raygun]

I made a lazy susan that I tie the heli down to I can set up everything just like it would be in the air but I leave the blades on for the torque of the blades.. Ray

[Solitaire]

Yes, Ron, you can use your backup servo for the tail. Just make sure the gyro is set to either analog or digital to match the servo. It also maybe slower to react to the gyro's input, so the gain may have to be adjusted. You may have to adjust the travel as well so it doesn't bind.

As far as what Phil and I are talking about, we just have differing methods of setting up the tail. I prefer to have all my blades attached when adjusting for tail authority. Ray and Phil's lazy susan idea is a good tool for this as you want to eliminate as much twitching as possible on throttle-up and a swivel device will allow fine tuning without actually lifting off.

Ronp, the stick position, regarding throttle, for setting the rudder is irrelevant. Since the rudder operates independently of the swash system, it won't matter where the stick is. Just make sure you arent giving it any right of left stick when centering the servo.

Also, you should plug the servo directly into channel 4 of the receiver when setting the rudder servo (completely unplug the gyro all together). When the servo is centered, adjust the location of the servo on the tail boom so that the tail slider is centered. Now, adjust the location so that it is ever so slightly past center in the direction that counters the torque of the main blades. This will prevent your bird from spinning on spool up.

Finally, plug the gyro back in, plug in your battery and start the adjustment process for your gain. This is best done on asphalt or concrete so that you can see the bird spinning as the skids get light, letting you make adjustments to your gain before you get airborne.

Thank you guys

Hey ronp, I tried that lazy susan method with the mains off too. While adjusting the tail I decided to go max throttle to see what kind of power my bird had, just coming from a old eco piccolo I was anxious to see, and blew up the tail. I believe in part because i had not set the end points.

There is a hobby shop right here in Jackson on County Line Rd that should have
what ever you need. Give them a call: Jackson Hobby 732-364-3334

Thanks Dlan

Well now I have encountered a new situation. Went through the head set up again with the new head that I installed. I was going to finally set up the tail , gyro, rudder and based on all the great suggestions I received was ready to go.
I plugged the motor leads back in, put the blades back on, /on the TX, plugged in the battery and I get some beeps but it's not booting up like it was. I get beeps but they don't go into the song. I have full servo control on all 4 servos and when I put the throttle up the swash goes up but no rotation. No motor movement.
Any ideas? Man I'm glad I'm retired and right now disabled because I don't know where I'd get the time to play with this stuff...LOL....ron
One other question I thought of regarding pitch sttin on the blades. Back wheni was trying to get my P.O.S. Eagel I was told to have the throttle at 1/2 stick and in idle up mode. All the videos I've watched still say to have the throttle at 1/2 but none of them say to have the heli in the idle up mode.. Which is correct because I just set zero at half stick and got +10 and -10 at high and low stick?

[Raygun]

It sounds like something happen to the ESC and it is not seeing the throttle points again if it is a rapid beeping re-set the throttle points or make sure your trim is all the way down.. Ray

[akphill]

throttle all the way down when you turn tx on throttle trim all the way down
check your solder joints going to your motor
left your gyro in hh mode while setting up new head thats how I ruined 2 esc's myself
