Testing under water video with Gopro Hero 3. Submarine R39 belongs to BMBC member Paul.

I've replaced the old 6v sealed wet battery with a lipo 3s,11.1 volt 2200mhz, 100c spectrum smart battery. so the 1st run was cautious i just fired up the centre prop to see how she performed, well i was surprised at the turn of speed she had on just 1 prop, and how well she planed, it was a little awkward filming and controlling the boat by myself as i was the only one pond side. this was not without mishaps though, see 2nd video
After checking the boat over she was found to be unmarked and no bits missing, not bad to say she hit the pontoon at full speed, took off and plunged back in at the other side.
So the second run i started on the centre prop and then opened her up on the outer 2, she shot forward and immediately stalled, dead in the water. luckily i could reach her with the ponds barge pole to pull her to the side. i found the fuse had blown , i had fitted a 20amp mini flat fuse, i didn't have a 30amp only another 20amp which blew just as quick, upon opening up the outer props.
any ideas anyone or will a 30amp do the job, or a 2s battery? help any suggestions considered.

I built this model during four long years. my Lulonga is nearly whole scratchbuilt model (about 75 cm long) except the steering wheel and position lamps.
The model has a plywood and balsa hull construction ,plywood decks,from hard polystyrene sheets made superstructure,laminated with veneer. Sidewheels with skew paddles, two DC 12V independent electric motors with gearboxes controlled by ESC. Electric LED lights, steam sound module, sirene and horn.Tx/Rx 6 channel HK 2,4GHz.
completion expected in spring 2014

RC Sailing No.118 - Out of Lockdown ! . 4th April 2021
Forgot my gloves ! - Forgot to charge the boat ! - Forgot how to set Gopro ! - at least we got a few clips of video - out of lockdown al last !.
Nice to see Bill & Ben back sculling on the Pavilion Gardens in Buxton !.

Just 2:48 minutes​ of video clips to illustrate the fun of Sailing RC Lasers ! .

This is a video of her build...

Well, it's been 6 months since the last video at SMBC... but we're back at the lake tomorrow with Scale & Sail (if it's windy) and socially distanced on the lakeside... so hopefully we will have some footage to share of the boats, maybe even some new boats? in the meantime here's a link to the last video I did. Enjoy

This is the four foot Sterling model of the Chris Craft Corvette with sound module installed. I was able to reupload the video after using "Handbrake" software. Appears youtube doesnt like lower resolution videos.

I purchased a small BT player which has a number of features including recording. It can output using BT to a BT speaker, so I recorded an engine sound (Detroit 4-53 for the seaplane tender) I found, and copied it a number of times using the player and the vid on the computer (paused the recording, ran the video back, started recording again, etc etc) worked reasonably well. Very hard to find a sound which is continuous for a decent length of time, especially sounds of older engines which may not exist or are in museums. Used the BT feature to send the sound to a small BT speaker sitting in the boat.

Now I need to find out how to get the sound to accelerate and somehow get it into my 'GT Power' engine sound unit files, (the sounds on that are in lots of small WAV files linked to the TX throttle movement (I think they are on an SD card and they just loop where you stop the throttle, and advance or retard to the next file as you move it) A bit of investigation is in order.😀

Just finishing up a Chesapeake Bay "flattie" skiff. The bottom flat and is cross planked Here is the video fo the build

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"!)

I tried to put this up in the How To Articles...but it does not have url upload capability. So here it is. This is a very good video on how to work with fiberglass with odourless resin. It is very simple and should make those who are nervous about this process feel very confident.
