Title: Another 1st time nitro build
Post by: bmclaurin on February 14, 2013, 05:15:11 PM: Been flying electrics for a couple years now, and I currently own an E5 and E7. Decided to take the plunge into nitro with an N5c. Can someone give me some feedback on my planned setup?

N5c
O.S. 55HZ-R DRS
O.S. PowerBoost II
Futaba BLS 156HV cyclic
Futaba BLS 256HV rudder
Futaba S9650 throttle
vBar Full Silverline
Rail 606 mains
Rail 96 tail
Pulse 3600mAH 7.4v RX-Ultra
Gryphon Extreme-Heli GVR-7020B w/ slide switch
Futaba R6202SBW rx
Switch-Glo Pro remote
Spektrum RevLimit rpm sensor
KDE backplate sensor bracket
O.S. bubbleless clunk
FBL rotors titanium turnbuckles

EDIT: If it matters, I use a Futaba 8FG Super TX.

Title: Re: Another 1st time nitro build
Post by: bmclaurin on February 14, 2013, 05:29:32 PM: My throttle servo is not HV, so I thought the regulator was necessary.

Post by: Kevin Feil on February 14, 2013, 10:58:13 PM: I ran a similar set up, insted of 96mm tails I ran 106 rail tail. Otherwise she is going to be a Beast!

congrats on the Build!

Best,

Kevin

The engine and pipe combo should be an absolute powerhouse!!

Congrat's on the new build, enjoy it! and if you have any questions just give us a shout. :)

My throttle servo is not HV, so I thought the regulator was necessary.

You could buy a voltage stepdown, that plugs in to the servo plug which would take it down to 5v
I think that on the vbar the throttle servo port is not the full voltage, so you wouldn't need a hv servo, don't quote me on this, you would need to check, I have hv throttle servos on all my vbar Helis.

Post by: bmclaurin on February 16, 2013, 04:36:15 PM: Thanks, guys. Picked up my kit last night, but the engine and electronics won't arrive for a few more days. Starting the airframe assembly this weekend. I'll post a few pics along the way. Just barely getting started at the moment.

Post by: bmclaurin on February 17, 2013, 04:27:04 PM: Well, finished up the airframe this afternoon. Now I'm just waiting for my engine and electronics, which should be here in a few days. Looking forward to maidening her hopefully next weekend.

Title: Another 1st time nitro build
Post by: bmclaurin on February 23, 2013, 01:13:01 PM: Starting to come together now. Just need to run my fuel lines, install the Switch Glo Pro and RPM sensor, and secure my antenna wires. I really like the Gryphon remote LED switch.

Post by: Darren Lee on February 23, 2013, 01:46:50 PM: Looks great! Where is the Vbar sensor?
Title: Re: Another 1st time nitro build
Post by: bmclaurin on February 23, 2013, 02:03:11 PM: On the underside of the servo tray.

On the underside of the servo tray.

I don't know if that will be the best place for the sensor, I have mine on top of the servo mount where you have the unit fitted, and works good with no problems.

Post by: bmclaurin on February 23, 2013, 02:57:14 PM: Noted, but honestly, what's the difference? We apparently have ours mounted on the same component, right?
Title: Re: Another 1st time nitro build
Post by: Darren Lee on February 23, 2013, 03:44:48 PM: I can't think of any problem with that location, just never seen it done before!
Title: Re: Another 1st time nitro build
Post by: bmclaurin on February 28, 2013, 03:13:40 PM: Well, she's ready to maiden. Hopefully I will get a chance to take her up this weekend. Although I'm confident that the guys at my club will help me out, just in case I'm the only one there, I have one question. Do you guys recommend disabling the governor for the run-in and tuning flights?
Title: Another 1st time nitro build
Post by: Chris Sexton on February 28, 2013, 04:35:44 PM: I disabled the governor for the maiden flight, but left it on for all subsequent flights.

I just didn't do much other than hovering for a few flights 8 I guess. Then slowly started adding more moves.

Post by: bmclaurin on March 06, 2013, 08:06:45 AM: I've run about a gallon through it now. Still tweaking the vbar tail setup, as it has a slow wag at the moment. Lowering the I-gain took care of about 90% of it, but I want to get rid of the rest. Mechanically, this is the smoothest tail of my fleet (links have been meticulously sized, etc.), so I'm 99% confident it's not a binding issue.

I'm pretty much clueless on tuning the engine. I haven't messed with the needles a whole lot yet, as I wanted to get a gallon or so through it before I started to tune. But this thing is pouring smoke and feels really rich at factory settings. On my last two flights, I tried leaning both the high and mid, but honestly I didn't notice much difference. I went about a half turn in on both needles, but I didn't want to go any further until someone with some experience can help me. I'm hoping to catch up with some of the nitro guys at my club in the next few days, so hopefully that will help. Right now, I'm at about 1/2 turn on mid and 1 1/2 turns on high from fully closed. This is on an OS 55HZR.

Post by: Chris Sexton on March 06, 2013, 08:59:13 AM: I had a slow wag in hover that turned out to be gov gain being too low. Of course I turned it up too much and then had a surging engine :)
