new synergy owner.

 As stated in the title this is my first synergy.  So far I like the heli, I did make a mistake on setup and it cost me dearly on the maiden so while wating on parts to get it back to flying.  I figured I better run thru a few question some are gonna be basic.

First short history, I have flown nitro for about three years experience has all been with a trex 600n.  On the os hyper 50, and 55.  Both with muffler pressure.  I fly on the spartan vortex use spectrum radio. 

Now to the questions,   

The bird in question is a N7, with Torq servos, BK tail all HV setup and vortex fbl, with an OS105 regulated motor.

First question:  On my first flight I had an issue filling tank (not use to a regulated system)  The pressure build up in tank from trying to fill caused a line to pop off and me to get the good old nitro bath.   How do you guys plub your system so you can vent the tank when filling?

Second Question:  What is your basic setup with rail 696 blades, (pitch, H,S).  Im a newer to 3d sport flight and nats style has been the extent and still not a guy pushing supper hard.   Just learning tic-toc, backward up right, still working on my inverted orientations.   So basics.   

Third Question:  What is your normal maint routine I have a pretty good preflight or I thought I did till this bird but I have adjusted my method a little so that will no longer be an issue either.   But over all Maint is more what I am interested in like say (every hundred flights check bearings or replace dampeners,  keep an eye out for play on this part or that part)  that kind of thing.

Fourth question:   With a pressure/pump style system is a header tank a good or bad choice?  I have always ran one on my ones with muffler pressure.  Just not shure when using back plate pressure.  Right now I currently do not have one installed just a lynx fuel magnet.

That is the main one for now sure there will be more in future.

Tks in advance for the Info.

to plumb the tank:

put a filter tee inline to fill the tank, and just pull the line off of the check valve to relieve the pressure while filling it up.

Setup:
696mm mains 106mm tails
HS 1950 (run 1950, don't try to run lower, it can cause issues with the motor, the gear ratio puts the motor in perfect rpm range at 1950, IF your running an OS105 anyway).

maintenance: the n7 is really maintenance free honestly. it doesn't take much to keep one going. dampers last a very very very long time, they do not need to be replaced very often. I replace mine when I crash and cut one, that's about it. the only parts that I can think of to check on any regular basis are the following: brass bushings on the OWB hub to ensure they are still lock tightened and not rotating, clutch stack bearings after a few hundred flights to be sure they are still good (they spin very fast, if they get notchy they can cause issues), the pins that hold TT gears on tail output shaft and front transmission and set screws that secure them (be sure you get them installed properly and use locktight).

you CAN use a header tank, but not needed IMO. just use a lynx MOAS clunk, and you will be good to go.

Hi Justin, welcome to the Synergy family Sorry to hear about the maiden, let us know what you think when you get it flying. The N7 is one of my favorite helis of all time, it just rocks.

1: For plumbing see the attached pic. To fill up pull the stopper from the pressure line to vent the tank, close off the fuel line to the regulator and fuel through the clunk.
2: The 105 is usually happy at 1950 rpm. Collective pitch varies per how you like the helicopter to feel. Start with 12° and go from there. I tend to run about 13.5°
3: Apart from everyday preflight checks, and cleaning after each session it is a robust design that shouldn't require much maintenance. I tend to crash before any routine maintenance is required lol. Annual tear down to replace fuel tubing, inspect bearings, clutch, dampers, etc and go over everything with a fine tooth comb should cover you indefinitely.
4: No need for a header tank unless you want to run one.

Thanks for replies. Good advice I can use.   I will keep you posted on the second attempt.
