For long term turbine storage:

1. Remove turbine from the airframe.
2. Stand the turbine up on its tail cone and run kerosene fuel thru the turbine until it drips out the tail cone.
3. Give the turbine a few spins.
4. Seal the fuel and gas lines.
5. Clean the exterior.
6. Wrap the turbine with rag and place it in a plastic bag.
7. Seal the bag and store her standing up.

If you are just storing the turbine for a month or two, you can just leave her in the airframe providing that the jet is kept away from high moisture area. After long storage, it is also wise to check your batteries and fuel/gas plumbings.

Thanks for the response. I suppose taking the turbine out of storage is as simple as wiping it off and installing it onto the airframe (?). I was surprised by the of pouring fuel down the engine...I guess that is to coat everything with oil.

Hi, I am now the proud owner of a 600R, and my Boomerang for it isn't due for a couple of months, hence the need for acceptable storage.

How about using a turbine corrosion preventitive compund such as Ardrox 3961? I use this on my full sized turbines to good effect. (I look after various Air Ambulace Helicopters) Or is Kero (Jet A1) better?

Can I ask why the need to store vertically?

Cheers,

Hi,

Flying fuel (5% turbine oil mix Kerosene) is best since we have a few O-rings inside the bearing tube and not really sure if some of these corrosive compounds are "rubber" friendly or not.

Storing vertically will minimize "sitting" oil or deposite on bearings. In addition, any unwanted oil/contamination will run out of the engine by gravity.

Storing the engine in a sealed plastic bag is also ideal to prevent rust. Eventhough most parts are made from aluminum, stainless steel, and inconel, the rotor shaft and bearing housings are still made from harden steel.

No worries, thanks for the quick reply!

Hi,

I have a PST1300R which I won't be operating for the next 6 months or more. I will be storing it by following the suggested steps.

But what about the fuel pump? When I removed the turbine, I just plugged up the in- and outflow lines on the fuel pump. So for my case, there is still kerosene in the pump. Will it be ok to leave the kerosene in the pump? or should I try to drain the fuel out?

Thanks.

Hi Isaac,

Fuel pump will be fine with fuel in the line. I would seal the in/out line and one convenient way is to loop the fuel line with an in-line connector.
