Default Equipment Installation (Rabbit)

Hello Eric and fellow jet owners, I am really a rookie, I mean a real rookie. I have a Jetmach 60 and I am about to start equipment installation. I am trying to learn this on my own, but I am seeing that may not be possible. The simple question is where does it all go? I have attempted to look at many of the photos of equipment installations posted here in the Jet Forum, and basically, each is different even for the same type of model. In one installation, the pump is located in the rear, in another installation, the ECU is here or over here, the shutoff mounted here or there, UAT's everywhere, fuel tubing and wires gathered or spread to heck and back. I do not know what is located under the equipment mounting boards. The manual has a line drawing that clearly shows connectivity but again, the actual equipment layout is questionable. Please provide me with some advice or direction. Thank you. Chic

There is no single way to do it.
Some ideas:
- Distance from fuel tank to UAT to pump --> as close/short as possible
- Distance from pump to turbine -> not critical
- Keep Pump and Receiver away from each other.
- ECU, Rx switch and fuel shutoff valve easily accessible
- Batteries located to help balance the plane (I'm not familiar with your plane, but it will help if you can find out if it tends to come out tail heavy, nose heavy, or just about right)
- Use an FOD protector for the turbine.

Good luck!

Some gear MUST go in a certain place, you can shuffle other stuff to get the CG correct.

The fuel tank (tanks) must go close to the CG because a jet carries lots of fuel compared
to other types of models & the CG will shift & the model become unstable if most of the fuel
is too far from the CG. The UAT, which should always remain full, can, however also be used to adjust
the CG.

Like Edgar says, I try to keep all the turbine goodies as far away as possible from the radio install. I don't
use equipment boards, they look great but I like to be able to trace wires & tubes if a problem crops up.

Just follow the turbine manufacturers plumbing layout & put the components where it suits you. If you can
chase up some turbine flyers actually at a flying field for advice that would be even better. Don't forget
turbine models have special AMA requirements & remember it's just a model airplane with a different
engine. - John.

There is no real right or wrong. basically, get your fuel as close to the cg as possible. But slightly forward is best. and the rest is where it will fit.

Then, you will find that the batteries will need to be in the nose.

The issue with a jet is that engines can have significant weight differences, and in turn, will change how much led you will need to make it fly.


I have a Shock jet with a JC Falcon, and I only needed a few oz of led, with some large batteries up front. (two 2200mah LiFe, and a 5000mah LiPo)

Thanks guys, I see that we have international contributions to this post which are all similar in the given advice. I will certainly follow your leads. Dr. Honda, hope to run into you one day at the Farview RC Club in the spring flying my Jetmach 60 with Nir. Even though I live in Virginia, I am a member of that club also. Again, thanks guys for the offered advice. Chic

You should look st the shokjet thread. The jet match and it and are the same plane. I have a shokjet. It is real easy to lay out the ecu, pump etc.

Thought I would give you fellows who shot me some advice a quick look at my progress thus far. Again, thanks for the help. Chic

Im not sure Tygon fuel line is a good idea after the UAT. I would use Festo line from that point forward.

In the photos, I am using the tygon line to cover the inlet and outlet portions of the UAT until I am ready to run the fuel lines. Thanks, I will use the Festo line as you suggested. What about running the tygon line from the filter to the tank? Chic

I have used tygon from the tank to the UAT with no issues. However the connections must be barbed (not festo) and the should be safety wired (http://www.dreamworksrc.com/catalog/Safety-Wire)

I cant quite see if the filter uses a barbed connection or a festo type. You have to make sure there is no air entering air thru that connection.

Perez, really appreciate your advice and will follow it to the letter. The filter is a Jetcat with barbs. Will safety wire both ends. Chic
