FEATHERING SHAFT. i was surprised that i was actually able to fix one just with pliers even tho the 4mm shaft had a really serious bend

MAIN SHAFT...what a pleasure not to have to struggle with removing badly sized main shafts.the bolts that attach the shaft to the head and the gears are confidence inspiring.

MAIN GEAR...my fault entirely, did not damage tail drive gear. uses 4 hole trex compatible 150 tooth...exi variety 3 for $8

TAIL BOOM....u will never see this thing descibed as "buttery soft"
like the guruz. cab be had for $2.50 ea

MAIN AND TAIL BLADES: the KB fluroscent yellow tail blades i got at helidirect really are larger than stock and throw the wind....immediate noticeable improvement

FRONT TAIL DRIVE GEAR....again my fault i keep wrapping grass around the tail the gear broke. i got metal replacements with setscrews at HD.

TAIL ROTOR HUB...unbelievably a tail rotor screw snapped and the blade went loose....i bought trex hopup tail hubs for $3 ea

TAIL ROTOR SHAFT.....it bent.i straightened it. these are cheap

SKID BRACE: still flew it with it half hanging off

KNIGHTHEAD BRACE

VERTICAL FIN HOLDER/BOOM SUPORT

FLYBAR got stainless steel replacemnts for much less at HD they bend, they straighten

SERVOS: your first crash you will probably wreck a servo these things are just fragile. plan on an immediate upgrade. i went to all HXT900s
and the Tx was modified as needed

ESC, Battery Radio, Gyro, Motor all still going fine. motor and esc get hardly warm after full pak flight.

I LOVE THIS HELI !

you could use better. this wil get warm after some flying though i have not had it puff yet.

i got 2100mah 20C fron dealextreme they work fine

seems i might have misinterpreted the intention with the neg pitch as the blueray came out of the box. pot A (right side) sets pitch and you can tune out all the neg pitch with that. i think there is some feeling in some quarters that having neg pitch in non idle up situations is a good thing. and given how the wind will take things i agree.

so in actuality you can do a totally electronic setup and trim.

of course you really then want to setup up right mechanically, but it's a nice exercise for the electronics.both birds have been very close right out of the box mechanically.

will get you in the air real fast

Looks like a good package. The pc programmable tx is interesting. I don't mind that setup. I do my programming at home anyway.

[Melnic]

If you look at my youtube site (user ID is blueray450), most of my setup tutorials are of the Rx ready version w/ the DX7.
My last upload was the basic RTF radio usage given the default T6config settings that came w/ the heli.

For anyone looking at this thread for referenc:
Left switch is Idle up
Right switch is throttle hold
Left knob is Gyro gain (center is 0 gain, CCW from center is Heading hold, CW from center is rate mode).

Frac, I'm curious where your gyro gain dial is and if you tweeked it.

After looking at the T6config defaults, I don't like a few of the default values and think they should change a little and made notes the other day. I'll post them this weekend for you to comment on Frac.

As you mentioned, my blueray servos came in pretty close to 90degree centers when removing the sub trim. I'm not sure rim each heli but if I compare my defaults to yours, we'd know.

The tail center on mine was pretty off, but it could be because the tail servo mount slid some in shipping. Something I'll cover on my next tutorial which will be setting up the servos. One could as you did, just set it up w/ the subtrims or one could go the 9 yards and use a swash leveling tool. I'll document the quick and easy way for new customers of this heli.


I love my blueray too

available in your neck o the woods at :

http://www.r2hobbies.com/products.php?cat=71

for $42 US.note this is for the tx the rx the usb interface the software and the satellite.

probably the rx alone is there somewhere too

Nice Vids!

Frac, I'm curious where your gyro gain dial is and if you tweeked it.

i'm using 2 gyros on these one is a colco gy400 cheapie HH and the other is the stock exceed/esky HH. the stock's pot i left alone the gy400 i turned the gain pot all the way up a la finless.

i did modify the settings so that rate is CCw and HH CW.

sure. i changed the entire setup. i set everything to zero and then did a mechanical setup, then trimmed lightly. i'll do the same eventually for the new one. *if* i stop having fun

As you mentioned, my blueray servos came in pretty close to 90degree centers when removing the sub trim. I'm not sure rim each heli but if I compare my defaults to yours, we'd know.

i'm pretty sure they are individually tuned, my numbers were all weird
and yet everything was nice and level.

probably why you are no longer happy with them because you did a real mechanical setup.

you will have to modify again when you get the hxt900s.

geez now that i'm flying around a lot i'm busting up servos all over the place.love those $1 gear kits.

Something I'll cover on my next tutorial which will be setting up the servos. One could as you did, just set it up w/ the subtrims or one could go the 9 yards and use a swash leveling tool. I'll document the quick and easy way for new customers of this heli.

i was just fooling around and got it balanced real nice. with no wind and some real effort i bet i can get a min no hands hover. it's so stable.

I love my blueray too

apparently a bit more than me

i have read about this befre and mine seems to be following the pattern->first the ESC gets warm to hot for no reason and then suddenly bursts into flame.

in my case i have unexplained heat with no throttle or other drain. i switched out the ESC from the first blueray which does not do this.

i was unable to fly the ARF because the motor had no power.i guess the ESC is teetering just on the edge.the other esc is working fine.

we'll see how xheli CS handles this....the ESC is obviously faulty.
the ESC is the stock Volcano

if your esc starts to get hot for no reason, don't fly. send the ESC back

frac,

I am going to get the Blueray based on your recommendation.

So after seeing your last message on the ESC, do you recommend then getting a new ESC with the package?

Also, I couldn't find the TX by itself on the website anywhere. I guess I'll just get the RTF package then and pay $10 more.

Thanks!

i think you shaould have a cheap spare on hand in case. i like supersimple esp since they are super cheap 40A ~ $13US

it 's not like everyone who buys an exi or exceed has a defective esc
i am sure xheli will make good on the bad esc.

my first bird did not have this problem. this is just a warning about a symptom that can accelerate to a surprising degree of hotness if ignored

the TX is item number 18H-EE0085 at the bottom of this page:

blah blah blah.


the esc now on it is getting hot and the culprit appears to be a hyberactive tail servo that was itself quite hot.

consider above report temporarily rescinded while i investigate further.

i am going to put a ubec in and see what effect it has on idle temp of the esc.

using a bec is always a good policy in case the bec in the esc has problems, the electronics will still be powered.

Well, placed an order last night and UPS show that it shipped out today from XHeli.

Although I am seeing something weird, it only shows 1lb for the total package, and that's the RTF package with the heli and the TX. I am excited about it, but hopefully they didn't screw up the order....

nah. they have a special shipping arrangement with ups all their packages are 1 lb.

the ESC is OK. other system elements were causing the problem.

i recommend that you add a ubec to avoid any power problems with the electronics.

Ah, that's interesting, never seen that before. Well, if that's the case, then I will be flying my 450 PE in 2 days!
