Hi there Richard and Ray
Yes, I have spent this afternoon re-checking the electronics making sure that they are working okay, not that there is much inside – just one speed controller, one servo and the fan. Ive been drying the internals out with the hairdryer gently and a low heat. Everything seems to be okay. (Touch wood – up to now)
Also, I have been making & fitting the spray defectors which sit either side of the intakes as on the original K7 Bluebird. Apparently the original Bluebird suffered the same fate (swamping of the jet engine).
Also, tomorrow, will be fitting the 3 spray defectors which fit directly underneath the slope on the bow of the boat. I am thinking of making them from light aluminium.
To answer Ray's queries – I am unsure if you noticed but the canopy is made from aluminium mesh and underneath the canopy there is a ducting straight through to the fan. Either side of the canopy there are cheat holes as you call them to allow extra air into the fan. Also, the overall dimension of the intake is slightly larger than the scale size.
I have been looking to see if I may be able to re-position the batteries – At the moment I have them side by side, roughly just behind the front plaining shoes of the sponsons . I would like to get them in line, but, I have get one battery underneath the fan which may be an impossible task.
The other thing I note was when we did the trials this morning – I decided to run the model on 14.8 volts keeping the 22 volt batteries in reserve – as I was totally unsure how the model would perform. The one thing I did learn was the characteristics of it for steering was terrible – even though the rudder is slightly larger than scale.
I am looking forward to my next trip down to the lake – but I might wait until next Sunday when the lads are about with their waders.
On Saturday I was testing the rudder servo and I had a 7.4 battery connected up just so I could check the centralisation of the servo – as the speed controller has the BEC built in to power the receiver. Devilment took over and I thought to myself go on give the fan motor a blip to see what it's like – what happened – I don't know if you noticed – the set of drawers on the wall behind the boat – 5 or 6 drawers flew out spilling all the components onto the floor and I spent a good bit of time finding them and retrieving them – note to myself – do not do that again.
John
