I folks new to the forum, so would like to to say hi, and also would really like some help
So I've made a bait boat and it's been doin the job ok, but I just want a little more out of it,
I'm currently running it on a 360 motor, 7.2v motor and mtronics viper 10, I'm going to upgrade the motor to a robbe 4105 drive system,
But Im struggling with the battery, what's the best voltage/ ampere? Should I use a lead acid or nimh? Thanks in advance,
Regards
Louis

Can You please post a pic of the boat Personally i dont think the Robbie one will do the job BUT if we can see a pic it would help immensly.

As regards to batts obviously a Minh pck is far pighter than a lead acid batt

Hi Dave,thanks for the reply, I don't currently have a pic, will get one the next few days, I just went abit more power out of it, but want the battery to last Aslong as possible

Cheers Dave, anyone else got anything to add?

Stavros · « **Reply #7 on:** July 16, 2012, 06:38:08 pm »

As a matter of interest how long is it,the Broadlands were approx 36 ins long and they ran this combo but were only on a 6v batt and were patheticlly slow.Oh I forgot to add one thing ESC forget the Mtronics and Go ACTion the mtronics you have got will be to small for the new motor

Also what can I use to attach the lid to the base? It's made of fibreglass and I would like a really strong adhesive that's also waterproof and will have a decent finish to it, cheers

Another thing, just looked at the 555 motor, I don't know if iv read It right but it consumes 9 amp, will that last long even on a really good battery??

Stavros · « **Reply #11 on:** July 16, 2012, 10:09:34 pm »

Right I think you have read it slightly wrong BUT I will stand corrected on that <what I think you have seen is the stall current .

Right then am I right in thinking you are having trouble keeping the lid on your boat,I used to have a Boradslands Boat does this one have a long cover on it practicallly full length from memory mine was held down with a velcro strip at either end,what you could do of course is to get some wing nuts and bolts and use them.Could you please post some pics of the Actual boat exteriro and interior shots of it

PM sent to yourself

Struggling to get a pic at the mo, can anyone add anymore, and does anyone know of a website, where I can find info on the Broadland baitboat, iv looked and can't find any info on them, cheers

Stavros · « **Reply #13 on:** July 19, 2012, 12:06:36 am »

Unfortuantly they went out of Business a few years ago

images of the iners as requested
sorry it took so long,
regards louis

Stavros · « **Reply #15 on:** July 20, 2012, 10:18:28 pm »

Right having seen the pics I will ask one important Question What is the propshaft made of as it looks to me that it is a plastic outer am I right ?? if so first job is to get rid of it and fit a Brass one ....same length as the original,The coupling will be Ok for any motor that you use.I would still go for the motor that I advised.Prop size also the same.

Dave

Doncasterlouis · « **Reply #16 on:** July 20, 2012, 11:33:54 pm »

Ok, cheers for that, are the plastic shafts not very good?

Stavros · « **Reply #17 on:** July 21, 2012, 09:09:38 pm »

Total waste of time they allow it to bend

Dave

Doncasterlouis · « **Reply #18 on:** July 22, 2012, 02:41:10 pm »

Is there some type of flexible connected from the motor to the shaft I could use, as I feel the motor is working, to turn the uv joint

Stavros · « **Reply #19 on:** July 22, 2012, 08:54:45 pm »

I think this is your problem the SHAFT is flexing ...get rid of it put a proper prop shaft in it and then try it,obviously yoou will still need to use the universal joint,this is what everyone uses and they are made for the job

Dave

Doncasterlouis · « **Reply #20 on:** July 25, 2012, 08:23:01 pm »

Hi Dave,
You have any pics of any boats uv built mate??

Stavros · « **Reply #21 on:** July 25, 2012, 08:45:39 pm »
