Now the sailing season is essentially over, time to get back to writing this blog.
Had a nagging suspicion the waterjets were still not quite right. Decided on another set of water tests to confirm.
First, as the lake was nice and still, left the model quietly floating by the dock for around 15 minutes to check for leaks. There was no water ingress from the jet installations!
Once underway, there was slight ingress from around the perspex panel installed in the inner stern. Nothing to be particularly concerned about as it was quickly drained with the bilge pump. See picture.
Will reseal when it is removed for finishing and painting this winter.
When observing the waterjets began to suspect one was still reversed. This might seem obvious but I use a single lever control for both motors, with the Tx Elevon control system. This makes establishing rotation difficult as the impellers are not visible.
It was. Anyway, easily corrected. The already acceptable performance has improved noticeably.
The jet performance is good and maneuverability using the nozzle steering controls only, quite satisfactory.
All need to do now is figure out a way to operate the reverse buckets automatically when the throttle control lever moves to the reverse part of the gate!
