Len Mount's turbine mechanics will be available from Starwood Scale models in a few short weeks. We will let everyone know when we have them in stock. More information is available at

http://www.starwoodmodels.com/produ...urbinemech.html

For those that do not already know, we are the west coast distributor for Jakadofsky Jet Engines (PJW) in North America.

Mechanics are available in 950 (2 blades) and 1250 (multi blade) versions with either a long or short main shaft. The cobra and UH-1C use the 950 with long main shaft.

Keeping it scale.

I have to say..

I dig these new frame sets that let the turbine be mounted high...very nice stuff, I can imagine that this will help out many scale folks

In life there is no spacebar!

Well, actually it takes a very large scaler to accommodate the engine when it's up on top like that. Think about it: there are very few full-size helos out there with an upper engine deck wide or tall enough to hide the turbine up there behind the mainshaft. I'm talking about helos where the engine(s) is enclosed, of course. Look at Len's Huey-in order for the engine to be inside the scale cowling, the body is HUGE!! Very nice, very neat, but HUGE!!
These mechs won't fit a 1/5th scale H500 but the low-mount turbine will. They won't fit most Jet Rangers unless it's very large, either. These are not negative comments, and you should know that I own one myself. I'm just saying that if you can only afford one turbine, you'd be better off with the low-mount version. There will be more scale applications for them.

No, why?
My name is Jerry Hicks and I've built a scaler or two....I just don't hang out on the forums as much as I used to.

LM mechanics

The mechanics are nice and compact and I agree with Jerry on the size requirements for a fuse. This will hurt your sales on these units as they are designed for Len's fuses, also the is pricing is well above what is currently available from other manufacturers. What advantages do these mechanics over the HP5 for example.

what is the service interval?
what type of ECU is utilized?
Fuel consumption per minute?
running temps?
ETC....

The important key difference with the PJW turbine is the improved reliability. The integrated direct drive gear box is extremely reliable and maintenance free and does not rely on belts in the transmission of power to the helicopter. The ECU included with the turbine was designed for the PJW engine providing complete control over startup, governed rpm in flight and shutdown. Startup and shutdown is completely automated and controlled from the transmitter. The service interval for the PJW turbine is 20 hours and the engine is serviceable here.

The photo of the mechanics does have to be considered in context. Indeed it is designed for Len's Huey and Tow Cobra and these fuselages are not for everyone, an 81" fuselage can't be easily transported in a sedan. For those that want to take on such a project, the mechanics with the fuselage are designed to work together and the final scale model is magnificent up close and in flight.

This version of the scale mechanics is just what it is. Don't think that we are ignoring the issue that this mechanics will not just drop into other fuselages. We knew this from the beginning but we needed to start somewhere and the Huey is our flagship.

Some more specifications:

Startup: Completely automatic ECU engine start and shut down from transmitter
Power: 5HP (3.5Kw) that produces 16,600 rpm at the clutch bell
Fuel Consumption: 4 oz/min (120ml/min) average
Fuel: Jet A-1 Kerosene with 7% Turbine Oil
Gas: Propane/Butane mix in a refillable tank
Diameter: 113mm
Length: 260mm
Weight: 1350g (3lbs)
Speed: 85,000rpm
Idle Speed: 30,000rpm
Exhaust Temperature: 400° - 700°

We are an emerging company that truely loves scale helicopters.

If you need a smaller mechanic mfor smaller ships, than just use those with the bottom mounted turbine designed for the Jakadofsky unit. Those mechs fit into most scale machines from Vario and other manufactures, To switch to other mechs is just easy, because the turbine is removable by unscrewing 6 screws...that`s it:

best regards,

Elliot

If you have any questions, just ask....
