Red Cat hydroplane by SimpleSailor Chief Petty Officer   Posted: 9 days ago
Hi. The HK controller is an Aquastar 120Amp water cooled which has suffered all of the burn outs and never failed. SKU: 9052000008. The failed motors were all 2848SL 3900kv Brushless Inrunner (WaterCooled) SKU:3900-2848SL. I have my doubts about the specifications as their watts and amps do not add up. I have a temperature sensor on the motor sending info back to the TX and usually after a full charge and a fast run it would get to 60°C, then I would cool it to 45°C before the next run it burnt out at 85°C when I wasn't paying attention. The new motor runs at about 45°C how ever hard it is pushed. Still using the 120A ESC. The new motor was in the HK sale and I don't think they do it now SKU:S2858-2630. It just happend that the water jacket for the failed unit fits it.

Battery problems by Patto Chief Petty Officer   Posted: 5 months ago
BIG MISTAKE I brought a 5300mha -50c-14.8v-4s1p-78wh LiPo battery yesterday. Bloke in hobby shop checked my ESC which is a TURNIGY AQUASTAR Watercooled ESC 160A. and said that it could handle that size battery. Giving the boat a test run this morning the ESC erupted in a huge cloud of black smoke. Not happy Jan will be ringing the hobby shop in the morning. Allan

Speed Controller by Haverlock Fleet Admiral!   Posted: 1 year ago
since you have a hobbyking motor why not use their recommended ESC. http://www.hobbyking.co.uk/hobbyking/store/__45159__Turnigy_...

HI im getting a Turnigy AquaStar 4084-620KV Water Cooled Brushless Motor what type of Speed Controller to go whit it? many thanks cliff

You might have to buy a gadget to tel your speed control how to work it costs £8 from hobby king send for a Aquastar programming box sp500/ep800 OK with out it itwon't work ??

Hi, The motors are turnigy aquastar 3660-1460KV watercooled brushless motors x2 The esc's Hobby King 90a Boat esc 4A SBEC water cooled. Batteries Turnigy 4000mAH 3S 20C Lipos. Bow Thruster Raboesch 108-01. Do you recommend a Mixer.

72" Electric Deep V Twin Motor Monstrosity by saxon5 Chief Petty Officer   Posted: 2 years ago
After much deliberation, boat is coming own from 72" to 60" because of an exponential electronics' cost difference to overcome the drag. Specs thus far are: Twin 4084 1050Kv Turnigy motors: http://www.hobbyking.com/hobbyking/store/__65411__Turnigy_Aq... They will be regulated by two monster ESC's: http://www.ebay.co.uk/itm/171874401282 Juice will be provided by two setups: Primary testing and cruising: 4S 25C 14.8V 5200mAh LiPo [Hopefully] Showing off: 2x 3S 25C 11.1v 2200mAh LiPo in series, creating (by my understanding) a 6S 50C 22.2v 4400mAh power source. Prop: X465 Octura RH to compensate rotation Rudder: TBC (opinions on welcome: Aluminium Rudder System 130mm from http://www.cornwallmodelboats.co.uk/acatalog/race-rudders.ht...

72" 6S Brushless Power by saxon5 Chief Petty Officer   Posted: 2 years ago
https://www.hobbyking.com/hobbyking/store/__65411__Turnigy_A... http://www.ebay.co.uk/itm/171874401282 Looks like I found JUST what I need!!

72" 6S Brushless Power by saxon5 Chief Petty Officer   Posted: 2 years ago
Have had a look at powerplant options. Turnigy AquaStar T20 3T 730KV/1280KV Water Cooled Brushless Motor SKYRC Proteus Water Cooled X520 730KV 1280KV Brushless Motor for Marine IM680 I like these as they can switch output power. Shame I'd have to bring the boat size down considerably to afford TWO of these! Still looking for a reasonably priced 150A ESC.

brushless motor by Lauriem Lieutenant   Posted: 2 years ago
Hi, I use the same motor on both my 46" Fireboat and on my slightly bigger Perkasa. It is the Turnigy AquaStar 4084-620KV, run with two 5000mAh 4 cell (14.8V) LiPo batteries in parallel, and this gives both boats a brilliant and potentially slightly overscale speed and a long run time. Go to http://hobbyking.com/hobbyking/store/__31678__Turnigy_AquaSt... to see it. Both boats are single motor, single shaft, 3 blade propeller, the Fireboat has 50mm prop and the Perkasa 55mm. This motor will produce 3kW in short bursts but is relatively lightly loaded in these boats so it has power capacity to spare. The kV value is just the rpm per volt applied to the motor so a 620KV motor runs proportionally slower than say a 1600kv motor which is probably too fast for this sort of boat, and it means you can run a bigger prop. For the speed control I use see my boats on this site.

Anyone understand this? by Dave M Fleet Admiral!   Posted: 2 years ago
Interesting. I'm guessing you are using LiPo batteries and as you are aware they should not be discharged below the manufacturer's minimum voltage. Some of my higher powered LiPos suggest a 3.5v cut off but you set the actual value in your ESC. A little math shows that the power (watts) of your motor is the product of the voltage applied and the current flowing so for a 120 watt motor at 12v the amps are 10. If the voltage drops to 6v the amps could then be 20. Haverlock has identified this as a likeley scenario and I would agree. Ideally your ESC should exhibit decreased performance before switching off the power transistors to protect your batteries, this then allowing you to run at minimal speed back to shore. The 120 amp Aquastar may offer advance protection but you would need to read the manual. All my ESCs stay dead if the battery drops below the set cut off and will not rearm until the battery is disconnected. I appreciate that you were advised that the ESC would rework after a minute but this is putting you, your model and your LiPos at risk. Unlike other battery technologies, LiPos chemical structure can change if the voltage parameters are exceeded. Once changed the position is irreversible and you will lose capacity and in the worst case there could be an explosion and fire. Dave

Anyone understand this? by lesfac Lieutenant   Posted: 2 years ago
I have just been out running my Perkasa happily blasting up and down the lake at full throttle for about half an hour until the battery cells went low and the ESC cut the power. As I was advised and since proved if left for a minute the battery comes back up again and I can usually tootle back to the side. I waited and sure enough got some headway but probably rushed it a little and the cells went low again and it stopped before I got it to the bank. I then found it wouldnt move after waiting and I had to wait for it to drift to the side. Upon investigating I found that the two 30 amp fuses in parrallel had blown. I cant understand how the fuses are ok blasting up and down but blow in a low voltage and low throttle setting. I replaced the fuses and everything works as it should. The only thing that occurs to me is if the ESC actually sinks power to prevent movement but that seems unlikely. The ESC is a 160 amp Aquastar Any ideas? Les

Advice please on replacement brushless. by lesfac Lieutenant   Posted: 2 years ago
Thankyou both for your quick replies It looks like another motor then. 😟 The ESC settings on the Aquastar 160 amp esc are Default Settings: - Battery Type > Auto Detect - Operation Mode > Forward with pause then Reverse - Acceleration > Medium - Forward Limit > 100% - Reverse Limit > 50% - Drive Frequency > 16KHz - Rotation Reverse > Normal What Is the drive frequency? I have the choice of 16KHz or 8 KHz Its amazing how difficult It seems to be to get useful Information. There were no Instructions at all with the ESC or the programming box. Just a set of specs on each.
