Acerca de este barco

This was a free plan in Model Boats in 1977 and was based on Vic Smeed's Sparkler (I think). Actually turns out to be Twinkler- see below!
I have built three of these over the years- I like them! This one was built from a laser cut kit supplied by RBC in Holland. It went together well but has only seen the water once- enough to tell me that the toothed belt drive wasn't man enough for the 540 motor, so I will have to shoehorn a direct coupling in there.

    Brianupyonder, if you are on Facebook, there is a model boat plans group and I'm sure the plans for Bobby are on there for free download. If not message me with an email address and I can get the file to you.

    I built the 14" one as a fire boat with working monitor, and now have a half size (10") hull complete. I don't think the radio would have fitted in that in 1977. Plans for it include a tiny brushless motor and lipo battery. I reckon a 33% might be possible with something like an N20 motor and small lipo, not sure if it would plane though. Maybe I need to get out more.

    I don't think you can even think about a scale with a boat like this, it's a bit of fun. The figures in mine are about 1:24 but yes, that makes it a pretty large launch!
    Your little one sounds interesting.

    What "scale" do we think the original size Bobby represents? If the front cabin door is even supposed to represent 5 feet then its a big old launch for the Thames.....I guess in reality Bobby is more of a cut off MTB or RAF rescue maybe?

    My latest attempt is now complete, but I have started a 14" from reduced plan version. It is tiny now I have the deck and chine cut from 3/16"!

    You are right, the 600 would be a very tight fit. I ordered a 385 and rubber coupling yesterday to give that a go - although goodness knows when!

    The one I built around the turn of the century had a Speed 400 I think and 6v power. It planed really nicely with that. 2020 version has a 540 and 7.2v, but I have a 380 size motor in reserve in case its too much. I can't see how a 600 motor can fit without chopping the first bulkhead unless there's a much shorter coupling available.

    Hi roycv,
    My first Bobby had a 540 and six cells, went very well and was stable. RCB recommend a 600 which might be a bit much. This one has a 500 of some description but I haven't got it going well yet- and won't for a while now. I have to revert to direct drive after failing with a belt drive so I might go for a 380 as space is a bit tight.

    Hi Juan27
    My third Bobby, this one, is built from the RBC kit. It went together nicely as has yours by the look of it. I do have the article somewhere. I know I've got the magazine as that's a picture of it. I'll look it out and let you know. I expect I could copy the pages and let you have them.
