Everyone’s asking me if we are flying yet?

Well the seaplane is ready and documentation is with the CAA, so we are awaiting the Flight trials clearance certificate and a good calm sunny day to fly.  According to the LMA, it usually take a couple of weeks for the clearance paperwork to come back from CAA and we sent the documentations mid-June, so it should be with us any day now, but the weather is a more difficult thing to predict.

We started the month with finishing off the floats. The polystyrene sheets needed bonding together with the foam and covering with the Ceconite fabric. We knew that the adhesive used to bond the fabric was reacting with the polystyrene, so we needed to experiment with different methods and possibly other adhesives and it was physically impossible doing it at work environment and the best way was to complete all these experiments at home.

The fun and games started when we had to transport the floats to my garage. My dashboard got all scratched, but somehow we managed to fit the two 2.5m long floats in my little Corsa.

The next problem was to adhere fabric to the float. That didn’t cause too much problem as we re-design the float to have ply on either side so the adhesive was just applied on the wood.

I also managed to iron the fabric without heating the polystrene using a very hot iron and touch the fabric long enough for it to shrink but not too long to heat the polystrene.

For the high speed taxiing we need to attach wheels to the floats and Pat came up with a simple idea of using light Aluminium to make a wheel caddy which connects to the floats.

The design is simple and effective.

We used the same principal for the back floats.

Jeff connected the fuel lines and the throttle servos and tested both engines for us and we are now ready for the flight trials.

There are a number of small tasks such as painting the RAF roundels, covering the nacell box, finishing the camera and avionics recorders  which are desirable but not flight critical which will be finished whilst awaiting CAA clearance paperwork.

Complete high speed taxiing at Brough and ship the plane to the lake to carry out the flight trials.
