what motor by RNinMunich Fleet Admiral!   Posted: 13 hours ago
OK. So it's 4" smaller than the Sea Scout I am currently renovating and upgrading from a 50ies Taycol motor to brushless! So keep the 'stuf' lightweight. When I asked the same question for the Sea Scout a few months ago I got the following advice from Canabus, who seems to have considerable experience in this field 👍 "All from Hobbyking. Motor propdrive V2 2830- 1000kv 370watts 3.175mm shaft(9190000328-0)3S or 4S lipo battery. ESC 30A car(HK-30A)( XT60 connectors required), program card (HKPROG-CARD)can be used on the larger ones in the series. Lipo battery Turnigy 1000mah 3S 30C (T1000.3s.20) 89grams 75 x 33 x 19mm or a Turnigy 1500mah 3S 25C (T1500.3S.25) 113 grams 80 x 34 x 25 mm both have XT60 connectors. Prop about a 2 blade 30mm 1.4 pitch" I actually opted for a 3 blade prop and a 3S 3000mAh I already had, but bought the ESC and motor recommended and am now fitting them cos it made sense, was not expensive and came pretty quick - make sure it comes from the UK or EU warehouse to avoid possible import tax from Hong Kong or USA !!! This would be more than adequate to give your boat some Oomph! It needs more than my cabin Cruiser! For the RC buy a complete set already matched and 'bound' so you have the minimum of fiddling about as a rookie😉 I can thoroughly recommend the Turnigy HT6, AKA TGY-I6 , ~US$45 also from Hobby King. In a couple of hours one evening I could programme two models into it and get it to do what I wanted instead of what the factory thought we would want for plane or chopper! Instructions are quite clear, logical and lead you through step by step. It comes with a 68 page manual! But much you can skip if you don't intend to go flying with your boat! Attached is a pic from my manual with German branding (REELY)! But it's the same beast as the TGY-I6, second pic!! The whole package should cost around a 100quid and you're RTR! The RC set has 6 channels so you have lots of scope later for special functions; fire monitors, lights, horn, motor noise etc etc 👍 By the way; the motor comes with 3.5mm bullet connectors, and of course I only had 4mm 'other halves' but you can also get connectors, loose or fitted to cables and adapters at Hobby King. (You can solder them on with your 4lb hatchet!!!) Hope this helps, Cheers Doug 😎 PS don't forget a suitable coupling to match the 3.17mm motor shaft to your prop shaft (whatever that is, 4mm?)

what motor by marky Commander   Posted: 18 hours ago
Am building the EEZEBILT RAF tender the hints and tips suggest a 280 or 300 brushed motor but on other posts in the forums brushless motors are mentioned ,both my previous boats have been static so this is a steep learning curve for me ,Q1 brushed or brushless ?.Q2 what size ? Q3 would it be easier to buy a RC set up complete rather than individual bits and bobs ?.Q4 will defiantly follow in the near future . Any help much appreciated 👍 Cheers Marky

Help! What's this? by spunky52 Petty Officer   Posted: 2 days ago
Robbe had a boat named the Eco-Star, me thinks. This isn't it but it's along the same lines. Once you seal it with radio box tape it is self righting. Should be a lot of fun. You could add a very small brushlees and would probably be the fastest at the pond...

Sea Breacher by Captain-Steve Petty Officer   Posted: 4 days ago
Thank you for the video of seabreacher dave....looks great.... running on 11.2 volt must make a big difference as it was nowhere near that fast when I tried it.....its now in bits and I'm going to update it to 22volt and brushless with a 150volt esc ....should be fast or blow up 😱

Seabreacher by Dave M Fleet Admiral!   Posted: 6 days ago
Hi Steve Plenty of suggestions being made. I use waterjets and you should be aware of the max revs quoted by the manufacturer. You exceed this figure at your own risk. I agree with the previous comments regarding brushless delivering far more power if powered by Lipo. Ballast is a crucial part of the equation and the Sea Breacher has a large volume of air in its hull which makes it very buoyant. Like a sub perhaps some form of ballast tank that can be vented may be worth considering. You really need to speak with someone who is into submersibles as they have the experience and knowledge of how best to proceed. The Model Boat Convention is on next weekend and they sometimes have submariner modellers in attendance. Good luck Dave

Seabreacher by Captain-Steve Petty Officer   Posted: 6 days ago
Great feedback guys looks like going for a brushless motor is the way to go....going to cost a bit for the upgrade so Im researching it first to get it right...

Seabreacher by canabus Commander   Posted: 6 days 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

Seabreacher by rolfman2000 Commander   Posted: 6 days ago
I think I would be tempted to go brushless with it. Far more power for the size of motor. I don't think an 800 brushed motor would have the revs to push much water through a 50mm jet unit. Even an 850 motor would be an improvement. But going brushless, you could get far more revs out of it. Best of luck with your endeavours, Dave W 😀

Seabreacher by Captain-Steve Petty Officer   Posted: 8 days ago
Hi I have a 36 inch model of a seabreacher dolphin boat powered by a 50mm waterjet and a 800 brushed motor on an 11.5v lipo.I have not got it onto the water yet and just wondered if anybody with a jetboat could say if this setup is powerfull enough

pt 109 by basilsdad Petty Officer   Posted: 9 days ago
a 30"scratch built pt. boat, I built hull from .8mm ply using a resized eezebilt 20" plan. the deck fittings were copied as best as I could from photos and drawings found on line. powered by 2- 2200kv brushless out runner motors through 2 20 amp speed controllers. twin contra rotating props twin rudders fast and light a pleasure to build 2

Tamar motor help by lezz57 Seaman   Posted: 9 days ago
Hi alan50 Have a look at the MFA brushed motors and run on 12v excellent web site goid information. Regards

Tamar motor help by alan50 Petty Officer   Posted: 9 days ago
Hi all Just got around to start building a Modelslipway 1/16 Tamar . This being my first model boat and RC I am at a loss to what motors to fit . I would prefer to install conventional brushed motors ,but the ones recommended a few years ago 600 eco are no longer available Would be grateful for any proven recommendations ,or any easy setup using brushless without cooling . Trying to keep it simple and not too expensive Thanks in advance for any comments .

Tank Steering by RNinMunich Fleet Admiral!   Posted: 13 days ago
Hi Dave, you won't find a Conrad anything anywhere else but on the Conrad (or Amazon/Ebay) sites! But if you look for the Turnigy HT-6 you will find it on HobbyKing, it's the same damn thing for nearly half the Conrad price. See pics. Pure badge 'engineering'! Also just bought some Absima LiPos 2s 4000mAh from Conrad, €40 each. Today I found out that Absima is in Nürnberg (Nuremberg) just up the road from here, same batt €25 😡😭 Conrad will shortly be getting an appropriate mail from me! NO more Reely stuff for me!! I found the HT-6 very easy to set up, amazing what they pack into a $45 set these days. My Spektrum cost 12 times that a few years ago and doesn't do an awful lot more and is more complex to set up 🤔 Won't mess with mixer boards or two stick motor control just yet. Can use the mixer functions in the TX 😊 Have tested the HT-6 with various ESCs; e.g. Graupner Navy VR30 and Mtroniks Viper Micro10, no problems. When the new 2s LiPos are charged the next test will be with a Turnigy brushless ESCs and the BL I want to put in the Sea Scout. Progress is slow but sure. Why do I get on faster with electronics than with shipbuilding!!?? 😉 You're right; Mode 1 or 2 (3 and 4 are also available!) don't matter much. With this set you can assign any control element stick, switch, or pot to any channel (i.e. RX output) you want, and very simply - not like the Spektrum🤔. Like it.👍 I also like having the two pots available for proportional control; gun turrets, cranes, monitors .... 👍 And still switches left over for lights, sound .... Very versatile 👍👍 Only irritation is it won't go into operational mode until all switches are forward and the throttle (left stick) is pulled right back - motor off for an aircraft - safety feature. Minor irritation for a boater but pull the stick back and all is OK and you can then operate normally. Used the spring removal method on my old Graupner 40Meg MC-10. That box was a pain to set up as well🤔 I could programme the radio ATE for the old Home Office Type Approval lab faster, but then - I wrote the software 😉 Cheers Doug 😎

huntsman plan by Black Dog Jack Seaman   Posted: 13 days ago
Model Boats magazine January 2016 ncluded a free plan of a Huntsman 31 complete with photos and a step by step build guide. Unfortunately the model is 24". I also wanted a bigger model so I redrew the plan double size. It wasn't too difficult and only took a couple of evenings with a some lining paper from B&Q and a calculator and voila! At the moment I am planking the roof of the cabins and trying to decide between a brushless motor and an old Weston rare earth brushed motor I used to use for fast electrics. The article in MB also ran into February 2016 where all the fiddly finishing bits were described, also with many photos. I expect one can obtain back issues from their web site. Anyone interested in Huntsmen should get these two issues for the detail alone.

3d printing by Midlife306 Admiral   Posted: 14 days ago
Here's another I prepared earlier, I found the file for it on Thingiverse, unfortunately the file made a boat 300mm long, so I printed all the parts at 200% size👍 I've got all the running gear for it now except for the water jacket for the brushless motor, come on China, get your finger out!
