I have what I believed was a 42” Fairey Huntsman which has been languishing in various garages of mine since I was about 15 years old. It’s in a bit of a sorry state. But now some 40+ years later, and with all this free time that has been thrust upon many of us, I would like a bash at restoring it to its former glory.

Having browsed through some of the topics in this forum and looking at some of the super models that have been built I think my Huntsman is actually a Huntress!

It was originally a Christmas gift from my Father in 1977 and it came to me as an unfinished shell. I completed the build and fitted it out with a Merco 35 water-cooled glow plug engine, and I used a Sanwa 2-Channel RC set.

It used to have quite a turn of speed and I’m fairly sure it used to plane.

I still have the Merco engine which is invariably seized after such a long period of inactivity. However, from what I’ve read on this and other forums it appears that IC engines are persona non-gratis on most local ponds and lakes. Fair enough really when I recall how much of an oil slick my boat used to leave behind it!

Things have obviously moved on a bit since my days of model making and I’m looking for some advice on an appropriate electric motor, battery set, and prop type to to replace the original IC engine. It would be good to get it going like it used to with the Merco 35. As mentioned it’s 42” (107cm) in length and weighs 4.45Kg in its stripped out state.

I’ve read through a few of the topics on this forum and I’m still a bit confused to be honest. Brushed vs Brushless motors, Battery Balancing packs etc… Any help would be greatly appreciated.

Thanks in advance,

Alan

Hi Alan – looking at the shape of the side windows and the length of the coamings I'd say it's a Huntsman 28. Also Veron did a 42" kit.

Dave, who's the Fairey expert will be able to advise on the size of motor. Definitely brushless!

Hi Chris,

Thanks for your reply, and thanks for clearing up the identification.

I had always believed it was a Huntsman, but confused myself when looking at pictures of the Huntsman 31, which seems to have panelled glass going further back down the hull than mine does.

I’ve looked at some pictures of a 28, and would agree that it is what I have.

So, thanks again for that!

Alan.

Hi Alan

Definitely not a H31. The bow is much more sleek and flared. When viewed in isolation it's harder to make the distinction between a Huntress and Huntsman 28. The race number doesn't help though as that number doesn't appear to have been used on a full-sized boat.

Great that you are bringing the old girl back to her former glory.

Here's a photo of the Veron plans which I think confirms it's a H28. Vic Smeed/ Model Maker Plans Service also did drawings for a 42" model.

Yes – it's quite definitely a H28. Huntsman 28 I would be inclined to fit this motor G46 Brushless ESC and run it on a 5S LiPo pack with a X50 2-bladed prop. You might have fun finding a suitable prop and coupling if the shaft is an old imperial size like 2BA.

If you do then it might be worth stripping the old shaft and tube out and replacing it with a M5 one. You should get away with a 60A ESC although it might need water-cooling. This would be the one for me 60A Marine Brushless ESC

Incidentally 2020 marks the 60th anniversary of the real Huntsman 28. They don't make 'em like that any more!

Thanks Chris,

It looks like my boat was probably built from the Veron plans. As I mentioned I received the boat unfinished so had no real idea of its history other than it was started by a friend of my Fathers and it was a Huntsman. I checked out your posts and saw you are in the process of scratch building a Huntsman 28 too. It’s looking good! I will follow your progress and hopefully be able to pick up some tips!

Do you know what the scale of a 42” Huntsman 28 would be?

Thanks again,

Alan.

Hi Dave,

Thanks for all that useful information!

One more question if I may?

Do the Electronic Speed Controllers plug directly into a standard RC receiver, or do you need a specific type of RC receiver which can accommodate an ESC.

The Huntsman 28 certainly doesn’t look like a 60 year old boat! I’m so looking forward to getting this one back on the water. Hopefully sometime before the end of 2020!

Hi Alan

42" model is a scale of 1:8, so half as big again as mine.

My build stalled last year because I took too long and missed the opportunity to paint it outside. Just got a bit more to do on the Huntsman 31 hull and I'll be returning to the H28.

It's been brought to my attention that the ESC I suggested only goes up to 3S. That would produce just 4660 RPM which isn't enough with that prop. A 5S pack would be the one to use, in which case you'd need a speed controller which could handle that votage i.e. this one from that range 120A brushless ESC

BTW the answer to your question is that you simply connect the ESC into the throttle output of a standard receiver. It will also supply the power required by the receiver, so you won't need a separate Rx battery pack.

Sorry-pardon!
