Hi,
I've just joined the forum. This is mainly a reply to Bill D203 but may help others - I'm sure I'll need advice going forward. I'm building the Model Slipway Tamar (you can see how I'm getting on at
http://modellifeboats.blogspot.co.uk/). The kit seems fairly straight forward so far, certainly more so than the Trent. The biggest challenge is making an operating transom door as no instructions are in the kit but even that's not so hard with RNLI plans, some paper templates and forward thinking.
Motor wise, I went for speed 600 ecos as recommended by Model Slipway and Westbourne Models where I bought from (a couple of years ago now). However, I have that set up in my Trent with 2 9.6v battery packs. Performance is good (still working on duration) but the motors run very hot with 4 blade 4mm props so I'm downsizing to 35mm props. Will see how that goes. I recent went back to Westbourne models who have suggested going to brushless. I am seriously considering this and will let you know how I get on as water trails for the Tamar are, hopefully, not so far off - I'm aiming for end of May.
Hope that helps
