More changes, (not again you say😐) this time the original nozzle was re fitted, as I found that the very clever improvement I made, (a flasher, smaller, better fitting brass one), wasn't so clever after all (can't be brilliant all the time😁) and was restricting the flow. The performance was quite a bit better today (still not startling) and it seems obvious now that MORE POWER will be the next step (have a higher KV, 35 sized brushless coming on the sampan to try).
Had a chat with a long time expat UKer (ex British army) at the pond today, and he mentioned that he has an Aerokits fireboat 'kit' still in the box he hasn't started, (you might be able to hear the conversation) and that he was modelling in the 60s in the UK, running diesels in his boats. He was sailing a Kyosho Seawind today (as was the other guy),- and they look like a nice little yacht, and sail well.
Finally got a good day, so raced down to the pond and threw the boat in. 2 problems, 1: battery had run down a bit with all the testing, and the new 18kg digital servo winch needed every bit of 4.8v, so functioned intermittently, meaning not much sail control, 2: jib boom needs a kicking strap to stop it 'skying' and tangling (knew it would happen but wasn't a worry). Apart from that, everything worked perfectly ( cheapo China Futaba knock -off rudder servo still worked fine on the low battery which is a bonus)
Sailed brilliantly like it did over 40 yrs ago, and as it's set will sail hands off on a reach, being nicely balanced, (even with the crappy jib,- which I had to make,- well actually my mother made for me,- back in 1980 after the original was stolen by a kid at the beach, while my back was turned😠) Funnily enough it was made on the same Bernina I used to sew (horrendously) the jib foot after trimming it for the boom a few days ago.
A few more things to improve and add, but pleased to have it back on the water. Another crap video, -seems to get blurry once it's been through the movie editor and You tube ) One day santa might bring me a Gopro, ("yeah right"!)
Looks like a perfect day. I find sailing very relaxing and quiet, with no engine/motor noise. Can be quite challenging though, especially when you need to bring it back in to the dock.
Hi the Graupner yachts are the best, I have a Gracia and she sails very nicely and such a pleasure to watch. She had a small change last year to the servos and works for ever on a 4 AA cell pack 2300mAh. I have a little less sail area and have a sail servo the same size as a standard servo and this copes OK.

Hi Peter, nice to hear from you and that the majority of Australia and borders have re-opened and that you guys managing to get back to the lake/ pond !.
Ok on your observations, for sails I mainly use ripstop nylon, mainly for colour variety and good light/med weather. I dont usually sail in heavy weather but I do have 1 suit made from a more ridgid sail cloth which certanly holds its form better. However, I do find that ,the ripstop does absorb streatch in heavier winds thus inducing a bit of "belly". I really must get hold of some mylar to try myself.
I dont recall cutting to a triangular shape as I use a template (see photo) however I recently joined up two 2 panels with double sided tape, then did a 3 panel suit (again in ripstop) which
added a batten like rigidity.
I do enjoy trying out other materials and design options within the Wee Nip design brief, but now also getting fun from filming other members boats from the "Camera Nip".
Take care Pete - cheers and beers !

Had a large moment of enthusiasm yesterday and fitted the jet unit and associated bits. Then it was time to wet its bum for a test. First off, the jet wouldn't suck water without pushing the stern down slightly, (as I expected due to the boats' light weight.) I added 300g to the stern and she was away😊 Happiness filled I were😁!. Reversing bucket works very well (even though it's a bit of a blob on the transom). You really need one if you don't want to go forward forever, trying not to 'sail yourself into a corner'.
I Need to waterproof the pushrod holes in the transom but the bellows I bought are too stiff and compress too much, so I'll have to come up with another method, (probably some deflectors for a start. Only a problem when in reverse with a bit of throttle on. Plenty of power with the 2s I was using, but motor is rated 12-24v so it would scream, -even with a 3s. I'll start with 2s and see how it goes. Might have an initial blast on the lake this week if all goes well, although I'd like to finish the deck bits first.
Just waiting for some Voltage regs to come so I can complete the electrical side with the fancy bits.. The mechanical and electrical sides are as good as done, Grahams timer is working perfectly, with the water pump and air pumps hooked up (going to install a VReg on each one plus the smoker).
RC Sailing hopes to illustrate a selection of RC Models filmed from various locations.
RC Sailing No 107 includes a broad range of Buxton Model Boat Club members boats that include Yachts , Tugs , Rowing boat , Submarine and other power boats.
Policing at the Pavilion Gardens Lake enlist a new "Rookie" from the Buxton Model Boat Club.

Out for a "chilled" afternoon with the "Wee Nip" - testing various camera settings and filming techniques from the camera boat under various lighting conditions.
Thanks for posting the wee nip video. I've never sailed or built one of these, looks like it would be a fun little boat to have, certainly would be easier to transport than most of my sailboats!

On Bank Holiday monday 31st August 2020 , Buxton MBC put on a display at Buxworth Basin in the High Peak of Derbyshire.
Ref Wikipedia - Bugsworth Basin is a canal basin at the terminus of the Peak Forest Canal. It is located at Buxworth in the valley of the Black Brook, close to Whaley Bridge. It was once a busy interchange with the Peak Forest Tramway, for the transport of limestone and burnt lime.
