Status: offline 		You caught me, DJ.  LOL!   The 9650 is a big servo, but amazingly, the CG on the helicopter is just fine.  I guess it's that battery tray mod I did.  I'm done with the rebuild.  I went out and hovered it in 20-30 mph wind.  Talk about crazy!  I didn't burn a complete pack on it, but I can tell you, I need to set rate mode on the tail because gyro holds until it gets a blast of wind then it's weather vane city.  Also, I need to bump the voltage on the 9650 to 6.0.  Also, the new blades I got didn't balance well, so I put Align 325 woodies on it.   Tomorrow, I'm gonna try out the Radix blades, again... only this time, I'm flying better than the first time!  But... I haven't slept yet today, so it's time to get to bed.

Gizmo... Loctite on everything metal to metal EXCEPT aircraft nuts; they're the one's with one rounded end like on the blade grips.  Everything else, blue loctite.  What to check before doing crazy stunts?  Dude, as long as you did as you said, it's all good!   Go out and tear up the sky!  Good luck!

I gotta go to bed.  I'm exhausted... at least I don't have to drive 45 miles to work tonight... I'm off for the weekend!

Happy 4th, everyone!

Scott

Status: online 		Me thanks the heli Gods for the subtrims on the DX7. The Hurricane 550 has all solid one-piece links on the swash and the double push/pull links on the servos. You can only flip/flop/switch servo arms so long, then still need a little subtrim to get the swash level.
I didn't mind though, as the Hurri is by far the most stable and easy to fly heli that I have ever flown. When set up right it hovers like a coax, lol.

Hardest part was setting up the JR G770 gyro. I usually use the gyro menu on my smaller helis, but it recommends using the gear channel travel endpoints for the gyro gain and rudder travel to set the piro rate. When set up right this thing is a dream to fly, and for me, easy to see at a distance too.

Status: offline 		You know, Jerry and DJ, I'm really torn about my radio.  While it's easy to setup and works great, I do know that without subtrims, I'm spending way too much time on finding the right arms.  And you're right, Jerryit's a pain in the a** swapping.  I'm also torn between the "bind once" feature of my Futaba with its one button binding, and the speed and the display of the Spektrum radios.  So, who knows.  I know there are pro's who use the DX-7SE and Spektrum seems to have won the hearts and minds of the public, so who knows?  I'm just torn.  I have a Futaba 6EX, but I can find a 7C helicopter version for around $120 and that version has subtrims,  I know I need a 7ch receiver because I use a BEC.  I dunno... I'm lost in this choice. 

I got up early to fly and it's too windy. 

Scott

Status: offline 		Scott, i was futaba hardcore for alot of yrs...and they still make a fine product...the way i ended up with a spektrum was when i bought the blade 400 it comes with one...so all i have to do is buy rcvrs for as low as 40$ bind em to my xmttr and woohoo i can store up to 10 models on the dx6i i think its 10...so i had 4 helis on it...then disaster struck as u know...i binded my first airplane to my spektrum and i lost all my heli setups, they all switched over too acro aka airplane...now that ive reset everything im almost afraid to bind another rcvr to it again, all the heli functions r working and the airplane (corsair) thats on it works great too...so right at the moment im a bit torn ..is the spektrum a good deal or is it more hype bs, as u know they had a big recall....ive got a big 6 chnl cessna on its way has flaps etc and im going to have to use my spektrum to fly it...so when i bind this new plane to it, if i lose all my heli settings again then that will be the end of me and spektrum radios!!!! ill go back to futaba and pay the extra 150$ or so for it...DJ

Status: offline 		Believe me, DJ, I feel you.  When I get the 500 esp, I'm going to have to invest in another receiver and because I've already got a 2.4ghz futaba receiver, I'm leaning that way with a 7C.  I can get the 7C with the same receiver I have now and feel good.  I go with the Spektrum and I have a better display, and more bells and whistles, but I have to worry about rebinding all the time and that's just another thing.  So, I dunno.

Status: offline 		Well, the wind died down this evening enough for me to get the tail nearly perfect.  Still a little bit more to do on it, though.  Rate mode setups are nothing short of a pain.  Tiny amounts of movement on the tail servo can cause big effects in the way the helicopter behaves, so I'm nearly there.  Just as a test, I flipped the radio to gyro and the tail is holding much better than before, still not perfect, but getting closer as I get closer to the neutral point in rate mode.  I'll get that in the morning, then I suspect the tail will be rock solid.   It's a pain to set up the tail in rate mode first but for my gyro it's required and I believe for all gyro's it will make the gyro and servo work much less in keeping the tail steady once in Heading Hold mode.

Status: online 		Well guys , I am not sure what all the differences are in the DX6i and the DX7, but binding the DX7 is easy. Put bind plug in the rx, then hold bind button on the tx and then turn it on. That is it. I have never had to rebind any of my helis even though I read a lot of posts telling people to rebind after making changes. I let a friend of mine borrow my DX7 to fly some foamies that he was building and didn't have a radio yet. Never lost any of my heli settings after he programmed 3 acros in it.

Ahhh Scott, the fly rate mode to set gyro syndrome, lol. That is another great thing about the JR G770 gyro that I put on the Hurri 550.
No rate mode set-up. In fact it does not even mention rate mode in the manual except that if you want to use rate mode to set the gear travel adjust to a point below 0. Anything above 0 is HH mode. Very simple to set up, except setting the piro rates to get the heli to piro at the same rate to the left as it does to the right. You change the rudder travel endpoints to set the piro rate the same in both directions.
You can then use dual rates to increase or decrease the piro rates.

My gyro, a Logictech 2100t specifies rate mode setup before even thinking about Tail Lock (Heading Hold), so that's what I do.  I have it pretty locked in now, no tail wag, so I'm happy I guess.  I'm not happy enough to repeat buying one, though.  My next Gyro is going to be a Spartan DS760 and it's going into a Trex 500 esp that I will be ordering this week! :-)  I haven't decided on a radio, yet.  Like I said, I'm torn.

Scott, I know all about setting up in rate mode first and it is a pita sometimes. I have to do it on my BH and my King2's as I am using Telebees on them and they say to set up in rate mode first. Don't have a Spartan but have read lots of comments about them, and they seem to be getting pretty popular.

Status: offline 		I think the DX7se is out.  It doesn't have the ability to use a buddy setup.  Of course it doesn't.  It's a professional radio.  So...  I read the manual and it's a bit more complicated with regard to gyro setup (figures, doesn't it?).   I would also have to buy two new receivers. While I can afford the receivers, I don't know much about them.  More research.  I want to buy everything tomorrow night at work so I will have it during the week to sort out everything and then start on the build next Friday night so I can fly all week, when I'm off. 

So far:
TRex 500 esp
New Radio and receiver(s)
New batteries
New charger
Spares (I'm thinking flybars, paddles, main gear set, tail/torque tube gears, blades(tail and main), feathering shafts, main shafts, etc.)
Tools, another 3mm driver, another 1.5 mm driver.
Lubricant, Lithium grease for the thrust bearings.

All totaled, easily over $1200.00. 

It's like starting over, almost.

Scott

Thanks for the compliment on the heli.  At least I know I CAN build that. :-)

Status: online 		Scott, if you do decide to go with a Dx7 I am sure that I can help you out with any set-up questions. I am certainly no expert , but I have set up my King2's, the Blackhawk and the Hurricane550 on mine without too much trouble. All different brands and sizes of helis, but the set-up is done the same. Just have to tweek the settings to suit the heli.
Gyro settings are not really that confusing, just that you can use either the gyro menu or the gear channel travel adjust to set the gain, but, you have the choice of using either one. For my King2's I use the gyro menu and for the BH and Hurri I use the gear channel.
