Hi all,
Not been araound for awhile as I have been playing with aircraft as well, I have however found time to scratch build a Fairy Huntsman which I now want to upgrade to modern electrics, a brushless motor and esc etc, should I avoid lipo's due to the heat issues or can I use them ok.
The hull is 42 inches long any suggestions on motor size would be appreciated, also esc size, the boat seems a bi on the heavy side.
Any thoughts would be appreciated.

Looking at the johnson website I am sure the motor is rated to 18v, the diameter of the case is the same as they give for the 700series motors, shaft diamter is 5mm the same as specified, so I think I will go ahead and use this set up. I need a speed controler to suit now any advice please.

HI Mark
It is a johnson motor the type that goes into electric drills, I tried it out and it spun very fast, I will have to look on the website and see if I can find out more.

Thanks for that Jarvo.

Many thanks for the r/c information, cash is always Important as I am retired now, so I appreciate the efforts. I did think about two motors and wish I had now but the prop shaft is in place so a fair bit of work to take it out as I set it in resin.

HI all
I posted some pictures a while ago on my scratch built fireboat, my first attempt after many years layoff, It Is growing but not very quickly.
I thought I would share a few pictures with the forum, It will not win prizes but I am enjoying the build, I have a 750 motor which I think will be ok. The next Issue will be the R/C which I am sadly out of touch with as It must be 30years since I last used one so I will be looking for some help.
I have learnt a lot on this build In particular about getting good quality ply, and not just anything, still good practice for another attempt In the future.

HI Allen
I have a very good lady who will creep in every now and then when the sawdust gets to deep and with the promise of a cup of coffee when we go out give me a hand.

HI All
After a lay off of many years I have now started to build a model boat again, I had the plans for the aerokits 46inch crash tender, so I thought I would have a go at building It.
After scratching around the workshop for various bits a pieces and buying In some ply I have made a start, as the eyesight Is not as good as It used to be It Is sometimes of measure twice , cut once then start again, still good fun and It Is testing the grey matter, It will not be a show piece when done but It will get me started and I can re-learn a few of the old skills, I will keep you Informed of the progress.

π Model Water Skier

HI There,
Nice thought but the piano wire will not work very well as when the boat tuns it will tend to push the skier outside the wake when he should follow it, fishing line would be better but the skier would have to be made to float in the skiing position, that would be difficult once the boat moved, a skier pulls from the waist not with arms straight so that would help with balance, good if you could do it.

π Fireboat Side Windows.

HI I have just found this forum, I am just starting to build this fire tender from a set of plans I have just managed to get hold of.
It is the 46inch version of this kit, at present I am just drawing the templates from the plans,
one of the things I cannot judge from the drawings is the shape of the forward cabin roof. from memory(I did build this kit many years ago) the front cabin roof is in three pieces the other roofs are all curved I think.
Can anyone help please.
