What is the KV of your motor and how many volts do you intend to use? The theory is that this is how it should be done and in practice I Have done this setup with Huco type couplings which turned over very smoothly but they could not handle the high revs ie14.000 The Radio Active couplings are first class but again I have experienced some balance issues and vibration with them. I worry slightly that the length of 2 couplings together is somewhat long but I may be totally wrong. All you can do is to try it I shall follow with interest

Many GRP based I/C powered before converting many of them to Brushless power. In Feb 2017 I bought plans from ebay in readiness for a family trip to Wales. My brother in law has a well kitted workshop in which he produced Sailing dingy kits before retiring. The aim was to produce this boat for the least possible cost. Thankfully there are lots of ply off cuts in Wales plus an 8x5 sheet of 1.5mm so I set about making my own kit during the time I was there. The motor was to be a Marx Decaperm selected from my bits box which I chose to set up using the geared drive. On the first launch performance was lacking to say the least so the motor mount was adjusted to direct drive but alas performance was not much better then everything stopped. The wires on the commutator had become unsolder end a common problem apparently I've now fitted a 3650 brushless stolen from an early attempt of a Huntsman 31 built for my Grand daughter which had replaced the Graupner 600, she is now 19 and interested in other things beginning with B. Having fitted the brushless a lot of vibration was experienced his was traced to a misaligned coupling,next outing will be with a huco type of fitting just to check it out roll on Thursday.

Over the years it's been powered by an ED 2.46 Racer a Merco 35 and finally my treasured OS61 VRM With a tuned pipe from Prestwich model boats. Now it's time for a a total rebuild so i,be decided to try twin contra rotating screws and brushed 600 motors. I'm looking to fit a superstructure akin to a Sea King. So far the hull has been stripped of all its hardware and all holes made good with resin and glass fibre tape. Currently making jigs to set up the two new propshafts On first test run brushed motors were very disappointing so onto plan B. Latest setup will be 2 x 3670 2100kv each with 100amp ESC. The lead acid battery made the hull very unstable so it's back to lipo batteries
Sunday morning is normally set aside for I/C but I have never been on this day but I do have I/C boats screaming to be used again. When you have turned into Fairlands Valley Park keep driving past the main car park down to the cafe which is on the left. You can park just past this building opposite the Sailing club. The club use the second lake they have a slipway and rescue boat. Hope this info is useful and you have a good visit
Me again I see you live in North London. I travel to Stevenage most weeks from Milton Keynes where we have overpriced and undersubscribed clubs. The journey time is about an hour but makes it an event to look forward to each week. The lake is about 10mins from th A1M Stevenage turn and no weed.
Good afternoon Robob have been following your build with interest. If you're from WGC I would suggest you look us up at the Stevenage model boat club. Very wide range of scale boats electric sailed Thursday afternoons from 2.00pm. Look us up on the website for full details.
[Score: 5/10] 30" Sea Ranger from Aerokits plan Single Propellor Direct Drive to a 2855 Powered by LiPoly (11.1v) Batteries Controlled Through Turnigy ESC - Comments: Still very much work in progress This Sea Sea Ranger is built from an eBay "Aerokits plan" which has some subtle differences presumably to get around copyright. The cabin sides below cockpit window had a reverse curve to the original but it was not difficult to undo this modification Well the sea ranger if now complete finished I a Ford maroon colour Belco paint been on the shelf since the early 90s plus some more before I inherited it, the cabin sides are cream self mix into a Crown paints b/w sample pot. Cabin rooves sprayed with white aerosol. The original motor at 3100kv was far too powerful so a silly little out runner has replaced it.

Radio gear is now 2.4ghz Futaba FS607. This one has been to the bottom of the lake after mounting a buoy. And back thanks to a friendly customer who did scuba diving for his retrieval efforts and twenty minutes below the surface.

Z class was for engines .12cu inch so I purchased my very first new engine an ASP12 watercooled,all kit up until this time had been sourced second hand. With a tuned pipe installed off to the lake we went. Needless to say it wasn't brilliant compared to the boats now being fitted with geared drive and bigger props,I was using 29mm & 32mm. In 2010 I converted it to the current brushless setup and it is still a boat that I would regularly take to the lake. It is a good talking point and the public do love to ask questions.

[Score: 8/10] 36"/4100g 36 Rater model yacht Powered by NiMH (6v) Batteries - Comments: Purchased at Henly on Thames wooden boat show in May 2016 again by my brother in law who likes to see me recycle old model boats. Thin GRP hull with stess fractures one mast and one thick canvas sail. Hull was coated with polyester resin and model aircraft wing cloth rubbed down and recoated with another application of resin rubbed down and painted with three coats Yellow machinery enamel after having been redecked with 1/16" ply fitted out with four turn sail winch and standard Futaba servo for rudder via flexible cable connection. As there are no restrictions on sail sizes and the original mast was in three sections at 196cm I replaced the centre 40 cm shorter in effect creating a no2 or B rig from Mylar type plastic sheet. Jib and Main made from four panels each and using a Claudio Gadget to create a curve in each sail. Having sailed on very calm day several issues presented themselves which need to be addressed in the sail department. Not too many photo's of this type about but I have found one on MYA website which I shall use to to make amendments i.e. new sails and gooseneck.

Have upgraded final look using photos from net based on actual boat 100% Proof. Should launch this summer 2016. Well launch date came and went no I finally got around to joining the Stevenage Model Boat Club in May 2017 before the boat finally got wet. With the power train setup listed above the huntsman perfoms remarkably well. Having done much internet research and downloaded many photographs I concluded that the superstructure on the kit was set too far back and it was duly moved forward to create a more balanced look. I had great difficulty finding suitable fenders so whilst on a family trip to Wales I coerced my nephew at Swallow Boats to design and 3D print some for me these are now installed pictures to follow
