Really like the look of Rebecca's fast patrol boat, great finish. Definitely considering building one in the same fashion as my recently completed Sea Urchin, but also considering brushless power - I reckon a motor with around 1000kv coupled with a 2s lipo or 7.2v buggy pack should do well - of course the lipo pack is much lighter, but the extra weight of the nimh buggy pack might help keep the boat manageable in our back yard pond😉.
Any way, I'll have to be content with enviously looking at your example - I have a grandchild's toy trainset to finish first...
Best regards, Nick
