Certainly sounds like it as the ESC and the motor are the only things left in the equation.


You don't have another one you can try?

[KitS]

No, this is the first boat I've ever had with a brushless motor and ESC so it's all new stuff to me.

[ChrisF]

Never thought of that. They're great when they work as they should. You'll get to the bottom of it.

Wonder, if with Dave's expertise and knowledge of the elecrtonickery, he only intended it to go forwards?

 Know any good Mediums?

No, the ESC was recommended for the SLEC kit version and mention that the ESC is forward & reverse,

Just had a rummage in my workshop and actually found the program card but I never needed to use it as the defaults (including F/R) were OK. My radio for the model was a cheap Saturn 4ch set from Howes. It worked out of the box as i recall.

My later Swordsman kit has the same ESC and the radio is Specktrum TX and a generic 'Lemon' RX. Again no problems.

I use left stick for throttle and right stick for rudder.

It does suggest there may be something amiss with the ESC.

Colin
ps: Have you used the programming card to set everything back to the defaults? (black boxes on the instructions)?

[Circlip]

Sorry, I didn't realize we were discussing recommendations, I though Daves boat came with the ESC and motor already installed


 Regards  Ian.

[Colin Bishop]

It did come with the ESC Ian, KitS is having problems getting it to work.

I had the same ESC in both my Faireys which worked fine.

SUCCESS! 


I sent the ECU back to Component Shop and asked them to have a look at it to see if I actually needed to replace it. They re-programmed it properly and it came back today.


I've put it all back in the Huntsman and it works a treat!    Great work on the Shop's part.


We could be trialling the boat at Wicksteed Park tomorrow, if the weather's warm enough.

Post photos!

Hehehe, I plan to, it'll be a momentous event for me.


The weather's too inclement for my partner so we're staying in the warm today.

[ChrisF]

Good news Kit.

We never did take the Huntsman to Wicksteed Park last week as the weather was far too chilly, but I trekked back home earlier this week and I've just tested the Huntsman out on Lydney Lake, and does she ever GO! 







I was a trifle put out finding that the crazy transmitter had reversed the rudder control for some obscure reason, so sailing her took some SERIOUS thought, plus a couple of geese decided to investigate what the noisy foreigner was on THEIR water.





They decided they'd go and check on the other end of the lake once I opened the throttle though! The Huntsman doesn't hang about, running about 3-4 times as fast as it's going in this pic, and planes superbly, looking JUST like the real thing.


She took on a little water in the bilges and I'm not quite sure where it's coming in yet, but a floatation test in the bath may sort that out.


I'm a very happy bunny now. 

[Colin Bishop]

Looking good Kit, it's nice to se it on the water again.

It is possible you might be getting a bit of water up the prop tube. Check that there is only a tiny amount of play in he shaft. I assume there is a thrust washer between the locknut and the end of the tube.

Another possibility is that when you slow down the following wave climbs up the transom and a few drops find their way over the low coaming along the back of the hull aperture.

Colin

[KitS]

I'll have a look there Colin, but the water was in two areas of the hull, separated by a bulkhead. One area could have been due to a prop shaft leak, but I'm not so sure about the other one.

[Colin Bishop]

See my edit above.Where was the second leak?

Colin

[KitS]

Yes, getting pooped can always be a problem with a fast boat. I didn't slow down fast enough for that, been had like that before, even in a full size boat!


The 2nd leak was in the battery/receiver bay, just aft of the motor bay.

[Colin Bishop]

In that case maybe the joint through the keel where the shaft passes through has opened up a bit causing seepage. When building this boat (and on the subsequent kit) the proptube was fitted after glassing over the hull so there could be a weak point maybe opened up by vibration. Dave epoxied the tube in.

 If the hull itself is leaking anywhere there should be some evidence of cracking on the outside.

Colin

[KitS]

False alarm on the 'leak' 'cos there isn't one.


I just held an extended session in the test tank (= bath..............) running the motor in forward and reverse, and not a drop to be seen. I reckon it must have been a sharp stop pooped it a bit, and I'll try and not to do that in future.


As it's forecasting snow here later    test sailing at Wicksteed probably isn't a good idea, but we may give it a go there at the weekend.

[ChrisF]

Yes, because of the design of the bow and the narrowness of the hull the Huntsman 31 is the one Fairey that dips the most when coming off the throttle.
