A great video of one of our customers flying his CARF Spark with a JetCat P-60SE Turbine.
Drop us an email if you are interested in a turbine conversion kit for your EDF Spark.
Available soon !!

Retracts with Oleo Struts are available as option.
The month of May features Rolf’s fabulous build Jet Arrows Mirage 2000.
The picture was taken in Germany during one of the Mirage sorties.
This EDF jet is powered by a 9mm Fan and 6-8S LiPo packs.
The Mirage 2000 is unique as it is manufactured by JetArrows in one piece (fuselage and wing are one unit).
Hence only the rudder needs to be glued on to complete the model.

Once again, have a great month and don’t forget to send us your pictures if you feel they should be featured as one of our wallpapers.
Done !! (well except for the pipe which has not arrived yet).
Once the jet pipe has arrived from Gumania the engine can be started and the plane will be ready for maiden.
In summary: a very nice plane to build – quick and easy.
(a pre-installed rudder -which was also available from Tamjets- will make the installation even quicker).
To mount the Dubro 600ml (20oz) tank as close to the CG as possible, I have installed a wooden frame over the retract bay.
The top surface of the wood is coated with a thin layer of silicone. Once dry the “anti slip” effect of the silicone allows me to install the tank with 2 velco straps. This makes removal easy.
The turbine bay and servos are protected by a layer of TamJets Heat Shield Blanket and fire retardant foam tape.
The TamJets Hopper Tank is installed beside the main fuel tank near the steering servo.
The retracts are operated by one of our AirPower EV-2 electronic retract valves. The brakes are driven by a AirPower EV-1 brake valve.
As the gear doors stay open once the gear is out, I decided to use a single action EV-1 valve for the doors as well.
The door open airline is connected to the retract down airline. This will open the doors as the same time the gear is deployed.
The door close airline is then connected to the EV-1 valve which is driven by a separate delay mixed channel on my JR Transmitter.
Once the gear is retracted, the door close valve is activated automatically after a 2 second delay (servo speed setting) and closes the doors.
The Turbine pump and ECU, fuel valve and kero start valve are all located in front of the cockpit area to make it easier to set the correct CG later (I calculated with a pipe weight of 80grams).
The last item still missing (it slowly travels to Singapore by German Post) is the Grumania P-20 Pipe for the F-16.
Double wall, titanium pipe with only 76grams.. very sexy..
The pipes are custom made and available from Grumania and of course via our webshop
Happy 2011 everyone !!
I finished the installation of the retracts and routed the airlines.
The intake duct is installed – I will have to cut it down later to install the fuel tank.
The EDF Version I’m converting does not have a rudder, so I decided to modify the plane and cut/install a working rudder for those cross wind moments.
The pictures below show how I cut out the rudder, added balsa to close the rudder and fin.
At the end I added a layer of light glass to the rounded edge so it an be painted. Looks quite good after the paint job.
The Rudder Servo is a Hitec HS-85MG which is installed in the small box below the rudder. A pin from the rudder will go into the small groove in the servo arm to drive the rudder.
Although we could not join the guys in Germany in person at the 4th Electric Jet Meet in Effeln last weekend, we can, thanks to the guys from RC-Network in Germany, bring you some great impressions of the meeting.
From small to large (and super large), all kinds of EDF Jet’s made it to this years Electric Jet meet.

We build this CARF Spark in Green/Blue Contender scheme for one of our customers.
The model is extremely well designed by CARF including a removable battery tray and receiver plate.
This Spark is equipped with the following components:
- TamJets TJ100 EDF unit
- Neumotors 1515/3D Brushless Motor
- TamJets retracts (designed for the Spark)
- TamJets Spark Trailing Oleo Struts
- MPI wheels
- TamJets Brakes
Servos used are various Hitec Digital and Analogue servos.
The model will be flown later with 5000mAh 12S Hyperion G3 Lipo Packs.
Due to the light weight of the plane performance will be fantastic.
To get an idea of the performance have a look at the below video of a similar equipped Spark:
