What's the difference between Lite and Compact Package?
As the ECU is mounted on the engine somewhere is needed to plug the battery into and make some sort of display for data to the outside world and this presents us with two options:
Lite package uses a small stamp size (42x24mm) shrink wrapped module which we call the "HUB", which the engine cable, battery, fuel pump and if you have one - the telemetry adapter, plus an external colour ECU display. This full colour graphics display has a touch sensitive screen which is bright and small enough to be mounted in the model, or can be unplugged when not required (its not needed for running).
As the colour display is quite expensive, it's useful that you don't have to have it permanently fixed in the model. The colour display also records the last 66minutes of operation and has a micro USB slot to install a micro USB card to offload the data to be examined on a PC easily, as it uses basic comma separated values that can be read in a spreadsheet.
Compact package combines the function of the HUB and display to a single unit. It's a boxed (35 x 46mm) black and white text type display with click action buttons. This eliminates the need to have a plug-in separate display but means you have to put it somewhere you can get your fingers to and it stays in the model all the time. The battery and engine also plug into this as does the fuel pump, and you can add the Xicoy telemetry adapter.
As this screen does not have any colour graphics or data recording it is the cheaper option.
You can add either type display later as an option if you choose.
I have two models, can I swap the one engine between them?
The "X" Series engines hold all the essential running data on the ECU mounted on the engine, even the radio settings. So it is easy to use the same engine between two or more models by simply adding a second fuel pump, plumbing and wiring to the 2nd model.
We saved you the hassle of listing the requirements by calling the complete set a "2nd Install Kit" which you can buy anytime and contains all the bits needed to fit out a 2nd model ready for you to swap the engine over.
The engine will control the pump just the same and there is no additional setting up to do when swapping them over, just prime the fuel tio the engine and it will take care of everything else. You can even have a different setup, you don't need to keep to Compact or Lite as you had in the 1st model.
Just be sure to order the 2nd Install to suit your correct engine size, simples!
