The BEST habbit you can pull out of this is to NEVER try to fly a new heli without putting a pitch guage on it. And I mean NEVER! I also never fly a heli if I have changed the blades for whatever reason without checking the pitch. Good habbit to have IMPO. It can save your bacon in many cases. As well as takeing away some uneeded frustration while trying to set a heli up while flying it.

Build it, fly it, crash it. Repeat as often as needed.

I hear ya Brian! What sux is I have dont just that to every heli. I had until this one. I got it in a trade and it was already set up. So I figured I would spool it up and if its tracking good, well? lol Mistake #1 for sure!! I can assure you this wont happen again.. Been kicking myself in the ars all day over this one.. Funny thing is, I got quit a few pms of people doing the same thing I did. Looks like im the only one that dont mind if its known public what a dumbass thing I did..hahahahaha
I just hope it stops someone else from making the same mistake.. JG

A good method to use when getting ready to test fly a new heli, is to have one of the other guys look it over. We do it all the time here. No matter how many you've done, another pair of eyes could see what you've missed.
that's why at big bird contests they have a safety inspection
2, 4 or six sets of eyes are much more better than one
sorry to see your crash it is bad enough dumb thumbing one in

Yikes, sorry to see that man.

Were all just mere mortals and can make mistakes,
NEVER try to fly a new heli without putting a pitch guage on it. And I mean NEVER! I also never fly a heli if I have changed the blades for whatever reason without checking the pitch.
I did some "repairs" crash damage to an Xcell 60 I had and failed to check the pitch range, I assumed it would be ok as there were no visible bent things in that area.
Fired it up , hovered and took off seemed ok, brought it in and slammed it into the ground, not enough collective to stop it.

I tell you what though guys. I may have done a stupid thing, but im still patting myself on the back some. Right before I spooled up Billy, my youngest daughter and myself were all at the flight line.. And right before I put any power to it, I asked them to get back by the tables just to be safe. It came down nowhere near us. But it very well could have!
Could have been a lot worse day for sure... JG

Hahahaha I wish! I just spent all my extra getting this one rtf.. Lets just say I am not broke. But family comes first and I dont have extra for parts right now. It wont be long though! Just not by next weekend im sure. I got my planks to get me by. And I actually have a 2nd R90 coming from Freezineskimo (Karl) that is rtf pretty much. But I still owe him some $ for it , so its not flying till its paid for. Just the way I am on that kind of deal.. But the idea is to have two so when this happens I am not in this same situation..

I know the new one you are getting is ready to fly, but you might want to check the pitches on it. Just ribbin a little!

LOL KC lmao, And yes James made sure we were all behind the safety fence. We all make mistakes, I mean look what happened to my Raptor 60 on its last flight because I decided to not preflight it and figured it should be fine since all was well the previous several hundred flights. I was wrong So please do flight checks before and after EVERY flight! It may just save your bird or someone's life! James is a great pilot and a great friend. Don't worry about it bud we'll get that thing back up in the air and we will make sure all is well.

Hahaha! You can bet your heli on that one Brian!!

KC, I know man!.. Thats one sweet motor you gave me in the deal to.
It was still purring there on its side in the mud!

And thanks for the kind words Billy. Glad you got to see a good crash today anyway.

Sorry about your crash, but I would say this is one of those 'avoidable' ones.

Here's how I do the pitch setup on my Raptors:

1. Put heli on a bench or floor that is level.

2. Pitch servo EPA/ATV at 100/100, pitch curve points flat at
50% all the way through.

I use a METAL servo arm on the collective servo, one that's tapped
for 3mm holes. I put it on close as possible to 90 degrees
when the servo is at 50% movement. (Turn radio on,
let the servo move to 50% per the flat curve, then fit the arm.)

I put a screw in all of the holes, then set a small horizontal
bubble level on them. I use the subtrim to get it EXACTLY
at 90. I do this because it won't be at a perfect 90
no matter how I fit it to the servo splines.
Once it's level and perfect 90, I remove the screws
and fit the linkage.

3. Adjust collective linkage so that blades measure 0 degrees pitch
with arm at 90 degrees and 50% servo throw. I do not
use the stock TT links for collective, I use heavy duty
ones made for RC car steering linkages. You can also
use the Rocket City links, anything you can adjust in
1/2 turn increments that will fit the ball on either side.

I put a bubble level in each of the blade grips and one
on the flybar hub. When all the bubbles are centered, that is
a PERFECT 0 degrees pitch. This will also tell me if
one of my links in the head is off and will make tracking
the blades easier. (Most of the time mine don't need
any tracking adjustments after this setup.)

(Much more accurate than you could set with a pitch
gauge, but you'll still need a gauge for the next steps.

Do not use the TT supplied 'gauge' that's molded
on the side of the upper frame. Get a pitch gauge and
NOT one of those crappy plastic 'T' shaped ones.
Get the Helimax one, the 'longer' the scale stretches out
on the tool, the better.)

4. Once I've got my 0 degrees pitch perfected, setting
the pitch curve is simply a matter of deciding how much
+ and - I want for a particular mode. I put the pitch gauge
on one of the blades and loosen the gauge a bit and level
the edge with the flybar. I hold on to it while I push the buttons on
my radio and while it moves to the pitch I want.

(If you are at 0 or 100 and want more, adjust the
EPA/ATV but make sure to keep it symetrical.
If you have to go one more hole out on the servo arm,
go back to step 3 and repeat. Most of the time you should
just have to back out the ball link one or two turns.
If you have to go one more hole in, screw the link on closer
one or two turns.)

I like to run a high torque digital servo with the ball closer
in on the arm, since the Raptors have that big pitch
arm + servo + other bits to move. A really beefy
analog one here isn't a bad idea either. Don't worry
too much about servo speed, you don't want your
pitch to get there before the throttle servo does it's thing.

On 60's to 90's, I run a 9253 tail servo with a governer on
my throttle and a 9250 on the collective.

I was just to over confedent and didnt do it. Other than pitch the heli was pefect. Tracking, no tail wag, etc. Would have been a sweet flying heli...

Karl,
Your one of a kind bro. And I dont know what to say to that man..
But Thanks!! I just dont feel comfortable flying something I have not paid for in full.. You never know what could happen in this crazy world. If something unfortunate was to happen and I couldnt pay you, I would want you to get back same heli you sent me.. But that really means alot bro.!! Thanks...James G
