Hi all As you see this is my very 1st post and it's a please help me one  

I'm off work for a year sick and getting very bored so i went and got a Hooben vosper perkasa 1/32 p150 mtb. I just love the looks of it. it has 2x 550 stock brushed motors already fitted with props
Now this is my worries i don't know much about electrics. i have always had nitro...
so
1 what esc do i use? I'm thinking 50amp?

2 what battery or battery's do i use? i don't need high speed but i do need long run times IE 40Min's plus if poss thinking 12v?

3 what radio gear to use? i will only be using 2ch only basic like me

4 I would like to use 1 battery and one esc to run both motors if poss?

5 what volt battery do i use?

6 very glad i got that of my chest  
Thank you all for your input guys

The spec http://www.wheelspinmodels.co.uk/boat/item/B-HB010-Hooben-Perkasa-1-32-Kit__f22f/ recommends 7.2v 3300mah. So any 7.2V Nimh battery would do. The bigger the amperage the better for duration.  I would have thought that a 20amp ESC would be ample. If you draw anything like 50 amps you will only get around 8 mins run time. If you have a radio for your nitro that will do for this. If you wire your motors in parallel (both positive leads to the same ESC socket) you can run them off the same battery.

Cheers Doug
I got the kit from hobbystores and they said i need a 80amp esc or a 50amp min   i would think a 20-30amp esc would be fine as well. but on noobens website even they say 80amp
so if i get a 7.2v 3300+   or a 7.2 5000mah this will be ok?

and i think i have a spare losi radio somewhere in the loft thanks again Doug atb karl

One of my boats runs 2/550s with a 25amp esc and a 7.2v 4600mAh racing pack.

If you have left and right handed props you will need to wire one of the motors up neg to pos and pos to neg on the esc otherwise they will work against each other, ie you will just go round in circles.

cheers for that dickyd  i hadn't thought about the l/h r/h props bit
whats the difference between using 1, 7.2v  battery pack and using 2    7.2v packs ?
 Looks like a 25-30 amp esc and a couple of 7.2  4000-5000 tamiya type stick packs..
This is working out a lot better then i thought and cheap..
Thank you my friend.

If you are wiring two battery packs of equal voltage in parallel you need one of these.

Hello Karl, please excuse me for jumping in but are you just having to add the electrics etc. to a ready built boat, or are you building it kit form?
        The reason I ask is I've had a bit of a yen for this kit for a while now ( http://vosper-perkasa.com/estore/product_info.php?products_id=49 ) and wondered what the build was like, if you yourself or indeed anyone else has built this kit I would most appreciate any feedback.
                       
                                                                  Regards, Tony

Hi Tony i got this boat new 2 days ago from the shop already made up.All i have to do is fit the electrics...But it looks very well made and is big,

I wanted the paula 3 by robbe but i could not get one on the day so i got this...wish i had got the paula to be honest with you as this is too big a job for me and is huge sitting in the front room.

I too bought a RTR version (from Antics), but a reduced 'damaged' one. On receipt it was actually wrecked not damaged, including both shafts bent unusable, however after some research and negotiation, got a much better deal on the remains which were basically the hull/motors. The rest I will rebuild/upgrade and hopefully have a higher spec boat for around the same price!

I too have some confusion over electics.... looking for ESCs they often mention 'maximum motor turns', I appreciate what that means, but how can you tell or is it an unwritten standard relative to the motor size, eg 550s?

I assume the 100A ESC they mention is to run both shafts, so a couple of smaller ones will hopefully suffice, might even try some HK imports, fairly cheap at the mo, £16 ish on Ebay!

cheers

I suspect that if the ESCs you are looking at are quoting number of turns, then you are looking at car ESCs, not boat ones. Try looking at the ACTion website or for Mtroniks Marine Escs (sorry FLJ ) These are designed for boat use and incorporate reverse without a delay. I would certainly hope that 100 amps was for both motors and even then seems a bit excessive - you wont get many minutes run time if that is really the current draw
