Finally got Gala Girl to the lake today her first time in water other than the bath, I went to pick up my meds this morning, as the pharmacy is close to Walpole Park I popped in to the car park next to the water and thought how ideal it was warm sunny and just the hint of a breeze, so strait home and a quick charge of batteries and down the the lake, she had already been trimmed so strait to the trials, I'd say from the off she performed as predicted and as a Springer should not too fast on full throttle and highly maneuverable, I didn't see any tendency to submarine with the modified Springer hull at her top speed, but then she is only 6 volt PB so if she was changed to 12 volt and a bit faster I can't say, to summarise I have no plans to increase her power as I think her performance was fit for purpose, she would get out to a broken down boat and push it back.
