Joe I was just curious on what you use, I have a similar one from Aeroworks. But you know, I have been using this Clineometer app and it is awesome. I cheeked it against the analog throw meter and the app works well. I also have a Accuthrow, but setup is a pain.
I want an incidence gauge/tool next, the Hangar 9 digitial one I hear is a good one to own.
[MENTION=4]3dNater[/MENTION] thanks bro, but I think I am good.

Got my rudder all set up. SWB arm and Secraft tensioners. The instructions are very clear on the Secraft website, I saw a pic of the little tubing pieces inserted in to the end of the tensioner, and I could only assume that they are supposed to crush against the cable via the set screw. First time I have used them, and they are really nice.
Got the fuel dot and main switch installed. I was going to us a flag/pin switch, but my luck I would loose the darn thing. On the Powesafe RX's they fail open so if the switch fails, it will remain on. The Flag/pin would work like a charm on the Powersafe.

That blue LED from the Powersafe RX is super bright. The camera just sees a Blob, lol
Got the fuel tank tested & installed.
I am no pro at setting up a gas plane, but this is what I did. The image above shows the lone running from the carburetor through the firewall.
Once inside the firewall, it goes to a Fuel filter (last line of defense for dirt), then to a T-Fitting. One leg of The T goes to the fuel dot, the other to the fuel tank/clunk line. I wish I had some fuel line clamps, because the wire ties scare me. I don't want the vibration to wear a hole through the fuel line, but I don't want the fuel line to come in contact with the throttle servo either. (ll keep an eye on it for wear.)
For the vent, I just made a loop around the tank and out of the plane on a 45° barb that I mounted and facing forward in the fuse. Not 100% sure about the loop/down line thing. But after playing around and testing, I observed that in a down line, the loop helps to prevent gas from leaking out in a similar way a toilet uses a semi loop at its base as a trap to keep stuff/stink from coming back in the house.
I saw that when the tank is facing downward, all of the gas moves forward, and the loop becomes the highest point in the vent line and traps the gas from going any further past the loop, thus preventing fuel from exiting the vent line and out of the plane. Sorry I made it sound so complicated, I am sure someone else can explain it much more eloquently. In short, the loop keeps creates a trap in a down line and prevents fuel from leaking out of the plane. It has Zero to do with having enough fuel for a long down line as some person tried to explain to me at the Airfield just Sunday.
Heck I may be totally wrong, I can only go from my own observations when me and the kids were testing the tank on a board with water. Any chance I get to get the kids involved with an RC project is a win win for me.
Next up is drill some holes in the cowl for the needles, and finalize my Choke situation. Doh.......,My fat fingers dint fit the cowl holes very well. The old zip ties between the standoffs to support the choke handle aren't so good for this cowl. So there you have it folks...I am so so close.

Just Do It
I have used that Clineometer app and still have it on my iPhone but don't use it for my plane any longer. It just requires an additional hand being it does not stay. Seems I always need two hands on the transmitter to get it just right, one to hold the transmitter and control pegged and the other to bump EPA. I have used the AeroWorks for some time and really like it but just might pull the plug on the Hanger 9 digital clamp on angle finder.

I really like those Secraft tensioners, I might have to get those. Can you install them using the existing cables in the plane? It looks like the added length of the turnbuckle might allow that. My cables have been loosening a little and these would sure make it easier to adjust.

Yeah you can, they do add a little length. If not they sell new 1mm cables for $5 bucks.

I use that Blue Stuff (sticky rubber /clay) to hold the phone on the control surface and not slip off. Until then, it was a kind of a pain, lol
Edit,...
I just saw the one from Hangar 9 is on sale for $59 so I bought it from Horizon Hobby. I don't need it so much for deflection angles. I want it for incidence.
Here is a nice little Demo of the unit.

Ray, I've used these on about the last 10 planes I've built, once you switch, you'll never switch back
As far as using existing cables... I don't think there is enough slack... however if you get the ones for the rudder too, you can replace all the factory hardware and upgrade your cable to the secraft 1mm cable too. The rudder couplers come with pins to use with a removable rudder, however you can just use an m3 bolt instead.
