Internal Combustion Ducted Fans (IC DF's) have lost a lot in popularity since the advent of real Turbines. We do however still offer our jet kits in a version suitable for IC DF and EDF (please read note). This allows people tight on budget to enter the jet scene. The initial investment is never lost as all our jet kits for IC DF can be converted to Turbine power later if required. For this purpose, we also offer Turbine conversion kits.
Contents of our jet kits for IC DF
The contents of our jet kits for IC DF are exactly the same as for the Turbine jet kits except for the following items:
All our jet kits for IC DF are optimised for the Dynamax or Ramtec fan unit, OS .91 VR DF engine and JMP silencer pipe. These are all a drop-in fit. Any other fan, engine or pipe will result in less performance and will require modifications to be made.
Due to low demand, we no longer stock ducted fan units, engines, pipes etc. We still have some spares to support current DF jet modelers. If you're looking for OS or Ramtec spares not listed, please contact us for availability. See also our price list.
Electric Ducted Fans (EDF)
Lately, we get many request from people who want an airframe for EDF power. Therefore we offer slimmed down versions of our IC DF jet kits for modellers who are willing to do their own EDF installation. Now, please bear in mind that our models are not set up to use an EDF. Modellers have successfully converted some or our IC DF models for EDF power, but they did it on their own, we don't have any specific instructions nor do we have any experience with EDF. All of our IC DF models were designed around the Dynamax/Ramtec type of ducted fan units, so the face of the air intake liners where it meets the fan unit measures 130 mm in diameter. This means that any EDF with a diameter of 130 mm or smaller can be made to fit and work efficiently.
So we emphasize once more that our kits for EDF are nothing else than slimmed down versions of the IC DF kits: no fuel tanks and no specific IC DF hardware, but including all ducting to suit the Dynamax/Ramtec type of IC DF units. The instructions only cover IC DF installations.
Please consult the Jet Kits pages for detailed lists of the contents of the jet kits for turbines.
