Boat chit chat by Alan999 Sub-Lieutenant   Posted: 9 days 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: 13 days 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 Sub-Lieutenant   Posted: 14 days 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: 2 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: 2 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 Captain   Posted: 2 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

propshafts by RNinMunich Fleet Admiral!   Posted: 2 months ago
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: 2 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: 2 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: 2 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

Dolphin 16 (19) by AllenA Admiral   Posted: 3 months ago
[Score: 7/10] 19"/1100g Dolphin 16 (19) Capable of 10mph and a runtime of 20mins Single Propellor (3 Blade 30mm) Direct Drive to a Graupner Speed 600 8.4v (3 Blade) Powered by NiMH (7.2v) 3Amp/h Batteries Controlled Through Chinese 320amp (10Amps) ESC - Comments: This is the Meccano Magazine January 1967 issue plan, built in balsa. I didn't do a build blog as the construction is well covered on the net. Started with an A4 plan and used Excel to enlarge it onto 9 A4 sheets. I chose something simple as I haven't built a boat for thirty years. Really enjoyed the build and re-learning how to overcome the problems that always arise. She is oversized being 19" long and having a 7.5" beam. She sits nicely on the water and begins to plane. Will upgrade the the battery sometime. The decking is worktop edge strip pre-glued but in future will use the unglued strips. The cabin was adapted to extend over the whole boat as there was little space for modern electrics. I will add in and out air vents as the motor will need to breathe. Also, the true model should have an upper deck and windscreen and this will be easy to add sometime in the future. Really surprised and pleased with results from aliphatic wood glue. The finish, which I am not completely happy with, due mostly to my own impatience, was achieved with Ronseal multi purpose wood filler, lightweight fibreglass laminate with Eze-Kote. Paint is Acrylics and Marine varnish. The electrics are: Acoms AR 201 Reciever, Servo Acoms AS 12, Cheap Chinese ,supposedly, 320 amp ESC and 7.2v Nimh battery pack. The Graupner Speed 600 8.4v, bought it cheaply some months ago, was already in one of my boxes and you can see the adaptation required to fit it into the boat. All the Acoms controls I picked up at a boot sale including an Acoms Techniplus Alpha Transmitter on 27mhz. Inside I used Hammerite Smooth Gold as I couldn't buy silver. Modern Hammerite is thin and squeamish and took 3 coats to provide reasonable coverage. One final rant I do like the new silicon wires but they are a nightmare to solder to a motor. I think I will use soldered connectors in future. So there we are, first model in 30 years and now so many models to build and so little time. Lessons learned...... don't be impatient.

Fairy Huntsman by rolfman2000 Admiral   Posted: 4 months ago
Dave M beat me to it. I have the same model. It's fitted with a speed 600BB motor and a 40mm prop. I use an Mtroniks 25amp speed controller (which is being changed to a 30amp Tio esc shortly so I can use my Lipos). It planes nicely on out lake, and seems quite good handling. Good luck with yours 😊

Fairy Huntsman by Dave M Fleet Admiral!   Posted: 4 months ago
As this is a refurbishment chances are it was fitted with an IC engine in which case you need to remove all the gunge and heavy mounting blocks from inside the hull as well as checking the propshaft and bearings. If you can get the weight reduced then I would expect a speed 600 motor with a 30 to 40 mm prop should suffice. A 20/25 watt ESC powered by a NiMh would also be suitable and keep the weight down. If you use racing props the current will be greater than if you use brass 3 blade props, and the bigger the prop the greater the current. As a general rule the prop should have a diameter of no greater than that of the motor. The voltage of the NiMh must not exceed the max voltage the ESC can handle. A higher voltage will reduce the current draw so a 9.6v may be better than a 7.2v and give a longer run time. If you already have batteries for other models I would use those but SLA's are heavy and may hinder planing. If you already use LiPos then make sure your ESC can stand the voltage and has a built in cut off to protect the battery.

ECS rating- confused by octman Captain   Posted: 5 months ago
I have read so much lately regarding the appropriate size of ESC for brushed motors that I am totally confused (not really totally , but nearly!). For a Graupner Speed 600 the info given with the motor is max efficiency current = 11 amps, stalled current = 70 amps, no load current = 1.8 amps. Do I need an esc rated at 70 amps or more, or a 15 or 20 amp Mtronic Viper unit be OK? Should the fuse be 15 amps, or something well above that but under 70 amps? Questions, questions! (should have stuck to sail!) Chris

Aeronaut Pilot Boat by Skipper44 Sub-Lieutenant   Posted: 5 months ago
Hey, I've really enjoyed reading this build log, I was wondering what the dimensions of your 540 motors were? because in the instructions (i'm about to start building it) it says to use a graupner 400 speed which is significantly smaller than the two graupner 600 speed motors that i was intending to put in it. Do you think they would fit? How much spare room is there? Many thanks for any help, Yours Tintin
