huntsman 46 by canabus Admiral   Posted: 24 days ago
Hi Pilot If you are using 540 can size (35-36mm brushless motor) a 3639-1100kv 800watts, 3648-1450 1600watts or a XK 3674-1900 1769 watts. All run on 100Amp ESCs, but check the maximum voltage they handle. I use car ESCs with the electric fan on top because they run cooler at slow speeds and no water plumbing required. The same with the motors no cooling. Props for these motors 37mm 2 blade or 40-45 mm 2 blade. If you go for a larger motor for a larger prop, a L5055-700kv 1600watts same ESC, but, start with a 2 blade prop about 52mm. Battery a 3-6S 5800mah or more with a C rating of 40 plus. I have used the 35mm motors in 34 to 40" boats, but, for my 46" Vosper Crash Tender I am going to the 5055. To large a prop will cause over heating of the ESC, battery and Motor. A in line amp meter(Hobbyking 9598000004-0) is the one in use. It reads the maximum amps, so for run speed amps slow speed up to maximum as a hit the throttle hard will give you maximum amps.

Painted in Canadian Coastguard Markings.

BRAVE / PERKASA MTB by Dave M Fleet Admiral!   Posted: 2 months ago
An interesting subject. There are details at http://www.bmpt.org.uk/other_boats_history/Brave%20class/pag... which may help your thinking. I do believe the third motor was mainly for slow speed use but am not sure. From a model point of view there will not be much space in a 37" hull for three motors and the necessary batteries and my 34" Perkassa runs at full scale speed on two speed 600 motors with a 9.6v 2800mA NiMh. I have seen three prop versions but the centre prop is usually free wheeling is not driven. If you really want performance then brushless and LiPo will give the best results and give plenty of room for 3 motors (28xx size), Escs and batteries. I guess your next step is to source a suitable plan for your chosen variant. I do hope you start a build blog

Billings Sea King refit by AllenA Fleet Admiral!   Posted: 2 months ago
The speed 600s should be great. I have the original Como 480s and it went well. Was much improved when I made sure the props were contra-rotating. I know, Rookie mistake but then I am still a Rookie.

I should have said that the two speed 600 motors are new.

Boat chit chat by Alan999 Lieutenant   Posted: 2 months ago
Has anyone bought a speed 600 motor from Howes lately. I have. Brand new and the motor is seized up.

How do I find out the voltoge of my motor without it burning out by octman Captain   Posted: 2 months ago
I have several motors that all look very nearly the same. One I know is a Graupner Speed 600 which is 8.4v but of the other 2, one is said to be 12v(was working with an 11.1 lipo) and the other one is unknown. It has a built in cooling impeller so probably came from an electric tool of some sort. Neither of these 2 have any markings or labels. Is there any way that I can test them for their normal working voltages without endangering them? Chris

Speed 600 motor by Alan999 Lieutenant   Posted: 2 months ago
Just unwrapped Speed 600 motor from Howes for my boat. It's dead as a dodo.Phoned Howes was told post it back for testing.As my bill for parts from them was £130 you would think they would send me a motor and I would post the duff one to them. It's all time as I'm in spain.

Crash Tender Shaft Tube Poistion by neilmc Commander   Posted: 4 months ago
Hi Doug, some amount of information to digest on this but I think I'm getting it some head scratching and hard work to come😁 Regarding motor replacement - love the idea of gold plated but when I take a motor, ESC and battery into the equation its about £80+. I currently have a Graupner Speed 600 7.2v motor, Ripmax Xtra Quantum ESC and a Tornado 3800mAh NiCad battery so would need to replace the lot from what I can see with limited knowledge in this area also.

Blown esc........ again 😢 by rolfman2000 Admiral   Posted: 4 months ago
Dear Auntie Plunkitt, bang goes another speed controller. Two weeks ago I blew my first, but that was my own fault, but this one, not sure. It's only powering a 600 graupner motor, so a 30 amp esc should be fine. But it kept slowing down, then nothing. The receiver was still powered up, but nothing to the motor. Any ideas ? Signed, yours Pained Wallet of Kidderminster😭

Seabreacher by canabus Admiral   Posted: 4 months ago
Hi Steve The Graupner Speed 900BB Torque specs are 6-40 volts, 6,500 rpm, 54A amps, shaft 6mm, dia. 51.5 mm, length 95mm and weight 645 grams. A brushless motor like the Hobbyking L5055 600kv is 11.1- 22.5 volts(3S -6S) power 1500watts, 55 Amps, shaft 6mm, dia. 50mm, length 55mm and weight 311 grams. On 3S=6660 rpm, 4S=8880 rpm and 6S=13500 rpm. The brushless motors are far more powerful and with an ESC with handles up to 6S(22.5 volts) you would have rpm's to drive a water jet unit. Canabus

Hi Dave, Yep, agree, to a certain extent. I have also had surprising results with 385 / 400 sizes; for instance with my 110cm heavy and cramped submarine. On the surface it outruns most boy racers 😁 Not exactly scale but all good fun. A little down angle on the forward planes and it throws up a beautiful handlebar moustache of water 😊 Not too much angle at speed or it sticks it's tail in the air 😲 No, the main question was that Fred already has the 700s so I simply suggested a decent match, 5mm shaft and so on. If he wants to spend on more motors fine. the the 3mm shaft would surely save weight, mostly through the smaller tube. Don't know the rest of the detail of the boat; beam, draft, safe waterline etc, but I would have thought a 3 footer would have a reasonable carrying capacity, like my 3 and 4 foot warships. Most of those run on multiple Speed 600s. And there I have the usual warship high length to beam ratio and associated stability problems! Like I said; he pays his money and takes his choice. Personally I would give it a whirl with the 700s since they are in the box! Maybe though with a 3 or 4mm shaft and appropriate coupling so he can adapt later if he wants to. Would still think a pair of 35 props would do the trick. Whatever, have fun Fred. Look forward to the Sea trials Report! (Wrote, read and commented enough of 'em in my old job!) Cheers Doug 😎 Oh no! Yet another thunderstorm just started, my terrace is already swamped 🤔

propshafts by Dave M Fleet Admiral!   Posted: 4 months ago
Hi Fred For a 3' boat the 700 size motors and required batteries will make for a very heavy model. The table Doug has provided indicates a speed 600 size motor would be more suited and would certainly be about half the weight. I have two 700 motors in a 4' hull for a RN Exploit model which does require the weight and can carry the large capacity batteries. Each motor can and does draw about 15-18 amps. I do not know your model but if it is anything like the Rivas then weight and internal space will be at a premium.

What motor have I got? by octman Captain   Posted: 4 months ago
I have 3 apparently identical brushed motors. One I bought new, one came in a model and one was given. The one I bought recently is a Graupner Speed 600, but neither of the others have labels on them, although everything else is 99.99% the same as the new one. The only obvious difference that I can see is that one of the older ones appears to have an impeller in it so that the commutator is not very visible. Am I to assume that this might be another version of the Speed 600, that needs to be cooled a bit more than a standard one? Anyone know? Chris

correct size of wiring by octman Captain   Posted: 4 months ago
I apologise if this has already been covered here but I am now at the point of installing the motor in my new model. The motor is a Graupner speed 600, and the specs are : Nominal voltage 8.4 V Operating voltage range 4.8-9,6 V No-load rpm 15500 No-load current drain 1.8 A Current drain at max. efficiency 11 A Current drain when stalled 70 A Max. efficiency without gearbox 75 % If I use 8.4 volts what size wiring do I need? Do I need to cater for the 70A current or the 11A current, or somewhere in between, with a fuse? Sorry to be a bit dim on this but I am confused (with most things these days!) Chris
