Confessions and Flight Report
So I kinda let this thread die a little bit. I did the mods as suggested by TMoore and Mike and moved the head down to the lower hole. This took some considerably more modifications. Here are the list of mods (don't want to get into detail unless requested and all this only took about an hour and a half):
1. Dremel down top of mainshaft
2. Dremel down top of century washout base
3. Dremel down guidepins (they were too long actually after this mod)
4. Switch washout control arms to century ones
5. Remove some material on the washout control arms (to prevent binding)
After I did all these mods, I had to readjust the links and setup the head again. Throughout all this, I made a very stupid silly mistake. I set one of my idle ups to 50% across. I forgot I had did this when I took it out to fly last saturday. On Saturday, I took off and flew in normal mode for a bit, just doing some basic circuits and feeling out the head. Once I was happy, I kicked it into idle up and I clearly had a hair amount of negative pitch cause this thing SLAMMED into the ground. I won't go into the details of exactly what happened, but let's just say, I was done for that day. In any case, I repaired the machine over this week and many thanks to Anthony (Jag72) for some critical parts that I really needed!
So, the machine was repaired and today was the day. Needless to say, I went over this helicopter with a super fine toothed comb and checked ALL of my settings. Once I was satisfied, I fired it up and took it out. Again I did some basic circuits in normal mode and once satisfied, I kicked it into idle up (on the ground this time though). Brought it into a hover and it didn't explode, so all is well. Once I was happy that it didn't self destruct, I proceeded to have my way with it!
How does it fly? AWESOME! I am EXTREMELY HAPPY with the way this machine flies now! The helicopter feels truly connected to the disk (unlike the stock head with brand new dampeners) but the dampeners still need to be replaced. The Rotortech paddles are a DREAM come true! The cyclic is VERY FAST responding and for the first time ever on a nitro, I actually NEED expo. What really impressed me is that the machine tracks EXTREMELY well! This is no doubt due the rotorhead and zero delta setting. I really expected the helicopter to be pitchy with the rotortech paddles but it is not. None of my machines tracks as well as this one does. In a high speed pass, I let go of the stick and it would maintain its heading perfectly, not pitching up or down. Interestingly though, in this high speed flight, the cyclic is still very responsive and I need expo. I don't need the expo because it overshoots when I center the stick (this happens with a pitchy setup) but rather because it is VERY PRECISE! Even flying fast, when you center the cyclic, it continues in the same direction. The collective feels more authorative than the stock head but somehow "soft" at the same time. The collective feels more predictable and "smooth" but will still punch when necessary, it's very connected to the collective stick.
Now here's the real question, does it fly like an Aurora? Honestly, I can't really answer this. I've only flown an Aurora once (Mike Wilson's at IRCHA, thanks again man) and it was late (sunset) and I was up REALLY high, oh and Mike's radio is setup weird (not really, just different from what I'm used to). So with all that said, it's hard to answer definitively but I will say this: it is definitely an improvement over the stock 700 head. All in all, the helicopter has the same crispness of an Aurora as well as its speed (in terms of cyclic). The stability and tracking really surprised me! All in all, I am EXTREMELY HAPPY with this setup!
Thanks for reading everyone!
PS I want to say thanks to FlyinBrian for the Avant head. Mike Wilson for letting me fly his Aurora. Mike and TMoore for the suggestions and how to. Anthony for the parts. And finally tr0cks for the "new" Synergy canopy I just bought
! And John (from the field) for the photos. And Al Austria (because he wanted to be mentioned in this thread to feel good about himself).
...now where was I, dh/dt = BS-dx/dt
I will fly you forever... till earth do us part
