Here is the prototype RF4 approaching completion of the structure - this only took about 2-3days thanks to our unique design (with features like tags and slots) that allow the whole structure to be "clicked together" -in fact it can be assembled without glue!
What do you get in the kit?
all the laser cut formers, ribs, spars side pieces, tailplane, fin & rudder formers etc.
you also get the cyparis stringers, Wing and Tailplane Joining Tubes,
Also available are fibreglass Cowl and clear Canopy.
here you can see the "Front Assembly" incorporating the engine bearers
The Wing also "Clicks together" and the plan is really just used as a referenceThe Wing structure nearly completed
The Wing is skinned as per the full size - you can also see the integral wing joining tubes which allow a quick yet strong wing mounting.
the prototype was flown with a 35cc petrol engine which gives a very spirited aerobatic performance, like the Skyhawks and Unipart Teams showed off these great aircraft with. Using a smaller motor will still fly the model well as a motor-glider.
This model is also suitable for conversion to electric power ....
Here is a video of the second flight of the Prototype - the kit is now 2kg lighter than this first one...
Here are some pictures of the RF4 flying at the Scottish Airshow - thanks to Alasdair Suterland for sending these great shots in
Now that's a LOW pass!
