Alan,

What are you using for the power source for these motors? (Type of Battery or pack)
and are you using one power source for both motors or one each?
Also what speed controls are you using?
Just trying to do my homework before buying the kit for this big beast

Hi Ken,
batterys are gelcell. 12volt 7ah x2,12volt or24volts. Up to you.
Esc,s 2x 90amp seaking water cooled

The current drawn by the specified motors at maximum efficiency is 50A. I doubt if you'll find any gel-cell of 7AH which can deliver this sort of current continuously. You should consider fitting NiMH or LiPo power, or be prepared to be disappointed.

I agree with FLJ, and also the boat in the video seems to be running faster than scale.

Hi i have been running brushless set up with gel cell for three years now and have never been disappointed. The motors are so over powered They would never pull the 50amps.lifeboat Paul also uses gel cell in his arun for two years and his not been disappointed.yes The Tamar in the video is over scale speed,it was done to see how it was on 24volts.when it on 12volts it runs at a nice scale speed.My jet drive lifeboat it the same.when i run it on 12volt (12volt 12ah battery) It runs for over one hour.I also run a fishing boat 6volt 7ah,runs for over 3hours.wyeforce tug 6volt 12ah runs for over 5 hours+ towing club dingy

That is a great paint job you've done there Russ. I'm quite jealous.

Thanks Ken

If you look closely theres a small scratch to the right of one of the windows, slipped with a needle file

I know colours don't reproduce exactly on a computer screen so could you tell me the colour of the R.I.B please.

I have to make one soon and wondered if it was yellow or orange !!

I found this nice picture of the Y Class that shows it almost the same orange as the cabin superstructure. In reality I think it is slightly darker orange.

I used Peugeot Seville Orange, it comes out more matt than gloss so seems to look ok on the Y-boat..

I really do think you should start on them pills again Dave....

CJ1 · « **Reply #40 on:** April 28, 2010, 06:45:39 pm »

Russ,
It's looking good. The Tamar has a real presence in the water....you can even forgive it being so ugly!
How did you seal between the deck and the cabin front/sides? Do you rely on the moulded upstand or have you fitted a rubber seal too?
Chris

6705russell · « **Reply #41 on:** April 28, 2010, 06:49:07 pm »

I have not decided what to do with the connection between Superstructure and hull, i might run a sticky back foam around the coaming to act as a seal and to stop any vibration, for testing i have just used three self tappers to secure the two...

Russ

6705russell · « **Reply #42 on:** July 03, 2010, 06:27:22 pm »

Update on the build, i have made and fitted the rear deck doors that cover the RIB......

Russ

CJ1 · « **Reply #43 on:** July 03, 2010, 06:53:23 pm »

Russ,
That looks good. Does the transom door open too?
Chris

6705russell · « **Reply #44 on:** July 03, 2010, 07:23:32 pm »

Hi Chris

The transom door is temporarily tacked with beads of epoxy which i can snap/cut off if i decide to make this a working feature..

Russ

Number 6 · « **Reply #45 on:** July 03, 2010, 08:29:55 pm »

I'll open the transom door when I push you back with my tug!!

Only joking, she's looking good, Dave

6705russell · « **Reply #46 on:** July 05, 2010, 09:37:34 am »

I managed to fit the boltheads to the engine access panels last night, fitted 180 and dropped about 30!

Russ

CJ1 · « **Reply #47 on:** July 05, 2010, 01:41:47 pm »

Russ,
That looks very neat.
Sadly, Adrian tells me that he has no more bolt heads in stock. If anyone knows of another source of these, I would be grateful. No hurry at present.
Chris

6705russell · « **Reply #48 on:** July 05, 2010, 02:25:34 pm »

I wonder where Adrian sourced his from? Perhap worth asking the question.....

Russ

Number 6 · « **Reply #49 on:** July 05, 2010, 03:07:20 pm »

Could ask the question but would you ever get a reply??

How long have you been waiting for instructions for the Tamar now?? Thought he was going to be having bolt heads done as an etching sheet?? Looking good though..Dave
