Last year saw the build of Fishing boat Patrica/May finished but in less than one year the cheap rudder servo gave up and stopped working. Out came the cheap job to be replaced with a Hitec servo far better quality one that will last. I have included some shots of the internals of the model  showing the new servo  and the wiring fitted last year. See link for original build on https://www.modelboatmayhem.co.uk/forum/index.php/topic,55460.200.html  Forgot to mention motor also changed very sluggish on full throttle

This serves to prove that, when building a model, access to the running gear needs careful consideration - nice one Stan

HI Ray spot on seen to many models with poor access to vital parts that may have to be replaced in the future. Poor wiring can also lead to future problems also.

Hi Stan
What was the motor replacement, also what 3 blade prop are you running???

Very tidy Stan   considering the number of components, wiring and limited space .....is this a model fuel gauze filter on the inlet side of the pump just to keep floating house bricks from the pump suction?

Keep an eye on that filter, I have found in the past that the aluminium body tends to corrode internally when used with pond water. This can lead to the filter gauze and the outlet blocking up.

Hi All will answer the following for you.
1 The filter is the type used by the model aircraft guys.

2 The motor was a M F A 385 this has now been replaced with a speed 400. The prop is from prop shop  30mm in dia  and is three bladed power is from a 7.4 lipo battery.

3 Yes the filter is aluminium but it is taken out and cleaned after each sailing and the filter is also cleaned.

All the modifications are now complete and the model is back in working order. I hope to have this model and the rebuilt lobster boat at Blackpool should you wish to have closer look.
