On the phone with Eric Clapp last week to order a Rabbit 100 for a Ripmax Xcalibur that should be here soon. He texted me a little later saying there was something a little different in the case and not to panic when I saw it.

That "something" is the the new Jet Central "Power Pack". It has been in the field the past few months being flown and tested and now they are ready for release starting at Florida Jets.

Description from Juan @ Jet Central;

"Information on PowerPack System

The PowerPack is not a complete ECU but is not only a connection box with the fuel pump and the valves to have a clean installation. In this new system, the ECU hardware and functions have been divided in two

There are two major components:

a)The PowerPack itself
b) Electronics under the front cover of the engine.

The PowerPack has the following:
Fuel pump
Solenoid valves
Electronics to control the power to the fuel pump Electronics to control the valves Electronics to comunicate to the HDT (s-bus) Electronics to comunicate with the turbine internals (s-bus) Electronics to read the pulses from the receiver Electronics to monitor Battery voltages

The electronics under the front cover has the following:
RPM sensor
Thermo coupler input
Electronics to control the power to the burner Electronics to control the power to the starter Main processor (the brain) Data storage (timers, operational parameters, data log, serial number)

There are two different Sizes of PowerPacks, one for the large engines (mammoth and Rhino) and other for smaller engines (Rabbit and Chetah) The main difference among both is the size of the pump and the flow rate of the valves. (electronics are basically the same)

PowerPack can be replaced and no programing or parameter changes are needed, because all info stays with the engine. "

As far as cost right now during the introduction there is no price hike.

All the current Jet Central turbines ---except the Super Bee--- will be equipped with the Power Pack.

Awesome I wonder if current owners will get upgraded as motors are sent in for inspections?

I like the idea of having electronics and fuel pump separate.
More in case of fuel leaks than anything else.
What does everyone else think?

I agree.

I was talking with Gaspar about it last summer.

I like it, wish jetcat had it,, It would be nice to have to only make 1 mount and everything be there. just my .02

I like the idea !!!

I think this is a risk you are already taking by having any fuel component in the same bay as electronics.

Jetcat has some engine models that are plug n play where eveything is internal, not sure how thats been working out. I do like this external "module" design hat JetCentral offers.

Interesting concept

Awesome Looking Product and concept

I prefer to mount my fuel components away from the electronics. You'll want the ECU mounted where it is accessible to plug in your HDT. I mount fuel components out of sight and close to the engine.

With this you'll have three fuel lines routed across your equipment board. They'd be better off integrating the solenoids under the engine cover for a cleaner installation, like some other manufacturers are doing.

Much better than " Under the Hood " ... Easier to repair / replace in the field if you have a problem / failure.. Very nice indeed !!! I like to SEE all the stuff, not just crammed away out of sight,out of mind.

Hello!!

I have the new Jet-Central powerpack inside my Jets Models Factory Ultimatun and I am really impressed about how it works.
It can not be more easy to install it in your model.
Works really nice.

Regards!!!!

I kinda like it. But I don't really mind separate components anyway. Is the new pump design brushless? I do like less components inside the engine, less chance you will have to send your big heavy turbine in for valve or pump service. I never thought much about separating the fuel and electronics components, kinda assumed the electronics would still work with fuel on them if it ever came to that. A big leak would probably shut it down...

Looks like a good idea. I have the Jetcat P-90 with Valves and pump inside the case, Inc Kero start.
It is my first trouble free turbine. However this looks like a good idea.

erbroens

Fantastic idea... congrats to Jet Central!

Maybe you should research before making such a statement.
Jetcat does not offer any engines with everything internal . However the P90RXI does have valves and pump internal. However the ECU is still mounted seperate.

Pardon me, I do not keep up with JetCat technology. All I read about them is in this forum, not personal research. Last I read all components were either internal or at least partially internal, however I could care less if they are not.

Sorry for any major decision making confusion I may have casued, and I hope that makes your diarreah go away.

The only problem I saw with mounting everything in the engine is the engine
becomes heavier & it's mounted at the back of the plane causing CG issues.

The system here allows you to put some weight forward. Having said that the
Powerpack looks incredibly compact (looks smaller than my Jetcat ECU!) so
I take it it's fairly light weight as well.

Being so compact are parts of it serviceable if, for example, a solenoid valve
has problems do you have to replace the whole shebang?

A guy doing the large Panther build thread made his own setup similar to this,
mounted all the engine accessories together as a module, good idea if you have
the space & he had miles of it. - John.

If you sent it direct to Mexico yourself, you better follow up with Eric on it. Last summer Eric had me send a Rabbit direct to Mexico for a warranty repair. So, I UPS'd it off to Mexico, put a realistic value of $2k on it for insurance. Well, because of the value UPS delivered it to a third party broker in Mexico who wanted $600 in import duties from Jet Central to forward it!

To look at the tracking, you would never know that it was not delivered to Jet Central as it simply says "delivered" and shows who signed for it. It took numerous phone calls to UPS to find out where the h*ll they delivered it. It really t'd me off because I paid $135 airfreight to get it there fast! I figured I just lost $2800 bucks.

It was several weeks for Eric and Jet Central to retrieve it, I don't know if they had to pay for it or not; they looked after it. The problem was apparently the $value that I put on it. I would never send another engine direct to Mexico again, I will send to Eric.

Is that how you spell Burner or does it mean something else.

I would agree with you on this. All they seem to have done is taken a simple system that works with the ability to replace individual components that might fail simply and cheaply with a more complicated system that will likely cost more to replace the whole unit should it fail.

It seems to me that with so many things these days people are over complicating that which was simple
