I have not put too much scale in detail but I am quite pleased with the overall finish. it is powered by two brushless 1250KV out runners and in the first sea trials I used 12v lead acid batteries. (That video was posted a few weeks ago - mdlbt.com/26793).
This video shows its second sea trial after I was persuaded to use lipos. The difference in performance is very pleasing.
Thank you Dave M for your help and advice during the build.
This is in fact my second Perkasa. I built the first one about 40 years ago (see photo), before the introduction of the GRP hull. Losing interest in the hobby some years later, I sold the boat and have lived to regret it. (I was also the proud owner of a 37" Aerokits Crash Tender powered by a Frog 2.49cc diesel. That went the same way!)
The first boat was quite lively powered by a Merco 61 i/c engine.
No pictures of either I'm afraid.
Hindsight is a wonderful thing.
