Helicommand HC3-SX on Spectrum

Barry.
If you set up your throw directions in the radio correctly per the diagnose tab you should need too go back and change any directions in the radio later.
Your setting in the rigid page should be ACRO! The swash will reach max throw before the stick does. That is normal.

Feel free to PM me and I will give you my phone number. I have set up four of these..

Bastard! No fair! I still have a ways to go. Will spend some more time with main set up changes and tail set up. Been studying up on the DX8 settings and programing the Kontronik 120HV. Not in a rush but getting itchy for the my first maiden. Adding a Scorpion backup guard.

[flyalan]

+1 on the backup guard.
I just received a new ESC for the E5. Will be using a Jeti Mezon. 120amps with a 15a BEC!  Just what the Dr ordered.
Hope to fly that combo this weekend if the weather holds.

Maiden flight just completed!!! No crash!!! Even took a vid.
Very twitchy tail was all over the place. head was squirrely.  There was a very noticeable head shake, guessing blade track?
Little dark and cold to mess track.
Dialed in tail and head gain and seemed to calm it down. Will try again tomorrow.

[flyalan]

Sounds like your head and tail gains needed increasing. Did you assign these so you can adjust from the radio?  My head gain on the e7 is 93. A little aileron bobble at any headspeed below 1650. I run 1850 any have no issues.
Let me know if you any help.

Yes I bumped both up and it got more stable but didn't reach a point where it bobbled.
65% on the Kontronik with this set up is supposed to be 2050 rpm.

Got rid of the head wobble buy adjusting blade track.

Second flight today got rid of wobble with a blade track adjustment. Bumped my minimum head speed up to 55%@2000, 63%@2160, 70%@2325. Seems to like the 2150 range.

Should you have expo added when making gain adjustments? The tail seems odd like its not lock in. I will have to make sure the slider is working? May not be adjusting anything?

[Tommy Wagner]

In the video it looks like the tail is in rate mode

Are you fighting to keep the tail straight ?

No to keep straight works. Just seems to wash out or not lock in. Think I will check to see if the slider has moved it from its default setting. May not have set it up correctly.

Hey Barry
What tail servo are you running?
Evidently there is at least one the HC doesn't like very well. The Savox HV tail. 1225 I think?
I have one and it works fine but that has been a reported issue.

BLS251 on the tail servo.

Tell you it's way different to fly this
700 then a 450. I like it and it isn't even tuned yet.

Funny story checked over this heli when I bought it used with 10 flights on it. After the first flight I noticed the pitch servo horn screw was gone! The arm never fell off! This was the only screw I couldn't reach with out taking it apart and took a risk with not checking it. Bad idea not taking it completely apart.
