Hi, Doug. I’ve attached a zoomed-in photo of the “Anchor Enclosure” that’s built into the starboard bow bulwark of the Wyeforce. There’s an anchor in the box but I can’t tell for sure what kind it is. Maybe a navy-type with the fluke & bill pointed inward toward the deck? A better photo is needed to be sure, so I’ll keep looking. The enclosure itself would be simple to build & fit to the hull. I remember seeing a photo of the boat’s foredeck area that showed what may have been a hawse pipe running inboard from behind anchor enclosure & down through the deck, presumably to a winch belowdecks? Does that make sense? Pete

Will try to be there, is there tea and buns for the elderly?

BTW TJ, to paraphrase Maggie Thatcher's immortal words to the German Chancellor; "You may call me Doug"! 😉 Cheers, U No Who! 😎

My pleasure TJ, get well soon👍 But as an ex Pat living in Germany for 30 odd years and having worked on several types of Fast Patrol Boats / Fast Attack Craft your spelling of Schnellboot is still making my hair stand on end! 🤔 BTW: DON'T cut the switch wires on the ESCs or you won't be able to turn them on! Cut the red wires in the 3 wire cables from the ESCs to the RX. Cheers, Doug 😎 BTW 2: boat looks good, nice work👍 I have a couple of 1/72 kits for E-Boat / S-Boot, hope mine turns out as well as yours! 😉

I had an MFA Spearfish in the mid 1990s and it was powered by an MFA Marlin or should I say underpowered. The Marlin was a good motor but was not really suitable for fast craft such as a powerboat or fast service launch like an M.T.B. I understand that MFA did an 850 which was for fast scale type models but in the end I put an Irvine 25 I.C in the Spearfish. At the time there was a motor called a Buhler which I think was Swiss . I used one😁 in my Perkassa running on nicads which performed very well. For the Aerokits P.T boat there are a lot of suitable brushless motors around and running on lipos will certainly give you all the speed you want.😁 Boaty

Mornin' John, agree re chromite, but still don't know what chroDite is! I only personally own the one Taycol Target. I got into this whole Taycol business while I was renovating Dad's old Sea Scout last year and decided I wanted a bit more Oomph so upgraded it to a 1000kV brushless, which gives goods results on a 3S LiPo. See the vids I've posted of the the 'Sea trials' (Lake Trials!?). So I decided to use the Target in the ancient Billing Boats Danish fish cutter I'm restoring and converting from static to RC. Figured the Target would cope OK with the plodding pace of a fish cutter😉 BUT, I wanted it to be reversible without cumbersome external switches or relays as recommended by Taycol / Keil Kraft in those days. After surfing around a bit a found a website where others had tackled the same problem. Looked at their solutions and refined them slightly. All I do is rectify the pulsed (square wave) signal from the ESC with a bridge rectifier (4 hi-current diodes in a bridge form in one package), apply the + and - outputs from the rectifier to the field coil so that it produces a constant magnetic field just like the permanent magnet of a canned motor. The two alternating (pulsed) outputs of the ESC are applied to the AC (~) inputs of the rectifier, which go + / - or - / + according to the command from the TX, I apply to the brush terminals just like a normal brushed motor setup. The output of the ESC is a train of either positive of negative going DC pulses. Pic 2 the positive train on the scope. Pic 3 the negative train. The larger and wider the pulse the higher and longer the voltage is applied and the faster the motor spins. So called Pulse Width Modulation (PWM). The gaps between the pulses are smoothed out by the inertia (flywheel effect) of the motor, and anything hanging on it - like a prop and a few million gallons of wet stuff 😁 Hey presto, a field coil motor that runs forwards or backwards on command 😊 Main thing is simply to separate the field coil from the armature coil (i.e. brush gear) so you can control each one independently. No rocket science but highly satisfying when it all comes together and works on the pond. OK, I'll look up Mr Lynch, wasn't he the Sarge in Z Cars 😁😁😁 Cheers, Doug 😎

HQ It looks a though it was built as fully working model from the pics.👍

Hi RNinMunich thank a lot put my mind at rest and nice to have the reasoning explained , also good to here from you, been a while, and good to be back making stuff again after getting the needles in my spine hope all is well with all members

Hi Steve im not sure now regarding motors as they have water cooling cans on but Surfury runs from memory a 1075kva motor Turnigy 160 A speedo watercooled on 2x2s 5200 lipo`s in series ie 14.4volts with 52mm mocom Alum prop approx 3hp. I think the Tornado has approx 2045kva motor same speedo + lipo`s x 50mm nylon prop both do scale speed to as fast as 40/61 IC and look great on our choppy water with just prop and rudder in the water. Both motors will take 6s if you like ballistic? All gear from Hobby king. Try the IC first, post some pics please

I too thought Chromite Doug but can it be used on it's own? I've only heard of it as an alloy or a catalyst. BTW great job. Never owned a Taycol but seen loads.👍 You don't recall Lynchie Tut tut😁

Hi TJ, that instruction is quite correct👍 It indicates that the ESCs have Battery eliminator Circuits (BEC) which means that there is an internal circuit which 'syphons' off 5V from the main drive battery to supply the receiver via the red wire in the ESC to RX cable. The ESC itself takes it's power from the drive battery. If all three red wires are left connected this will cross couple all three BEC circuits and may well damage the ESCs. The RX only needs one power supply! 😉 In my multiple shaft boats I usually disconnect all the red leads from ESC to RX and fit a separate RX battery. Cheers, Doug 😎

Don't remember Joe Lynch but John Bluthall was brilliant 😁😁😁 PS OK, I'll leave the shafts at 6mm, less a tiddly bit for the oil film! PPS Apropos lathe spares; I'm having a little trouble finding 6x6 tools for it. the Proxxon spares are a bit pricey🤔 Oh well, there's always the grinder! (Also Proxxon!!!)

Yup, John bluthall and Joe lynch about 1970 if my memory is good. Cheers Colin.
