Presedent Perkasa Fibreglass hull
moving along nicely all running gear installed 2 x 1400kv EDF Motors with 2 x 90amp watercooled esc,s running on 2 x 11.1v 5000mah or 2 x 14.8v 5000mah twin rudders 45mm X props if it runs anything like my other one I will be happy still lots of finishing touches to be done
Thanks Sandy it is seriously fast two 1400kv motors running on 4c 5000mah lipos 90a watercooled esc I have just sold it as I am nearly finished building another Perkasa with the same running gear the deck fittings & armaments are from Battlecraft I will post some pictures soon regards Bob
First trip out 100Mtrs coupling broke, calmest day for weeks took an hour to get back!! Built from plans supplied by Colin Smith. 38/32 brushless motor, 125A ESC, 4 cell lipo. When it went it went! Motor, ESC and motor mount water cooled. I will get a new coupling and try to get a video of this hope we have some more calm days.
My son's boat , started life leaking like a sieve and fitted with a brushed motor . The brushed motor did however serve the purpose of being a trainer for him to get used to the boat and controls . He now has a brushless inrunner water cooled and 3 cell lipo's giving great performance and duration . Home Surf is Needham Lake in Suffolk
I have a MFA Piranha almost finished in my shed and a MFA Spearfish I purchased from a model shop in Cromer. That shut down not long after I purchased it. That's still in the box as new. I intend at some point to put in a brushless motor. I have one already. I got both Motor and Speed controller the same as in the ProBoat 29" Blackjack. I already have the ProBoat Miss Geico that is a maniac on the water. So I'm hoping once I do the Spearfish that will also be awesome.
Hi Boatshed , Yes all MFA seem great boats . As for the Spearfish I have a Thumper Overlander in mine 2nd hand and cheap . if you want the wow factor in yours look to fit a Leopard brushless in runner as the result is fantastic . Look it up on YouTube couple of films of one ripping round a pond 👍
HI heres my thunder tiger ATLANTIC POWER BOAT, with a water cooled brushless motor & ESC,dose 25 miles plus had it 12 months still flys named it annie after my wife, I all so have a saint tropez cruiser. 😀
HI guys I've been luckily enough to of had the chance to buy this boat at the Heywood bring and buy.
It's in 1/16 scale and is four foot long. it's a complete scratch built hull using plastic sign bord.
The hull was built by Nick Rigby from our club in Bury.
All the rest of the detail has been done by his friend.
At the Monment she has the props installed but no motors.
I will be fitting her out with a couple of 900kv brushless motors and a couple of 90amp esc's all water cooled.plus two 11.1volt 5000ma lipo's in parallel to give a long run time. Hope you like the pictures!
HI Alan I have a Atlantic challenger. I burnt my speed controer it was 100 amp so I have a 120 amp now water cooled in it its the fastes thing on my lake and it looks the part. 😎 👍 malc. K. M. B. C.
RTR minI electric speed boat with proportional 2CH RC. 280mm loa (11")
Good boat and fast. Watercooled brushed motor. Normal problem with commercial mini-boats is lack of proportional RC but this is fine. Battery life about ten minutes - low freeboard and takes on water but electrics/RC have proven resistant to regular swamping!
I liked your boat. I also have an 11 inch boat with an extended exterior rudder that brings the length to 13 inches. Mabe the exterior ruder helps to keep water out of the boat this sort of rudder is seen on gas boats in usa.
Not your typical submarine but certainly an unusual semI submersible. Scratch built by fellow club member Brian Clewes this is a most striking looking vessel. Fiberglass hull and moulded perspex window. Home built waterjet uses a large 900 (I think) brushed motor, water cooled speed controller and 14.4v LiPo. Looks really spectacular on the water and Brian is working on the ballast to enable the model to remain just submerged. Video to follow in due course.
Thanks to all those that made suggestions about making the Suction Hoses, here are my efforts. The boat looks OK now thought there is much to do still. I am using two Johnson drill motors in paralell with one 50 amp ESC & 20A fuses in each motor + supply lead, all running on 8.4V NiMhi. the current props are 40 X 21 three blade. The boat is fast enough but battery life is short and the battery is very hot after the end of the run. I water cooled the motors and ESC. I will try some smaller props and 7,2V to see if there is an Improvement.
gearbox fitted, tested today with 8.4v graupner, running on 19.2v nimh. GPS Data logger installed, measured at 14.63mph, sound like a jet turbine!!, and this video was the slower of the 2 props tested.
Improvements with gearbox, motor is stone cold (it is water cooled, but was still hot as direct drive) , quieter, longer run time, esc cold, now able to upgrade from 2 blade 40mm prop to 3 blade, and possibly 4 blade, amp draw much less. Video taken at Newsham Park, Liverpool. Handling is now difficult, as its going way too fast, but its great fun! and might go faster, with the motor thats been fited tonight, watch this space!!
well that was the distant memory of brushed motors!, way back when we had gas lanterns instead of LED's 😀
Unfortunately I cant remember the ratio, I think it was 2:1 from memory. it was later converted to brushless. Has not been run for two years since the bigger brother fireboat came along. I keep thinking just put a brushed motor back in it, and have plodding speed, it looks silly doing all that porpoising, and the bigger brother can give me my speed fix 😁
Maybe a little more bow weight would stop the problem , my Spearfish used to do that all I did was put lipo length ways and it stopped , but yeah if your happy with the bigger being the faster then go for it 😊
This is my Sea Hornet which was rescued from Ebay see photo 1. Gray (Froggyt996) recognised it as a Sea Hornet even with the hideous cabin attched which the prvious owner had made. Also see the propshaft angle in photo 1 - would this have ever worked? Gray again restored this for me, I wanted a mahogany boat which looked like an italian speedboat and this is what he did for me see photo 2. Photo 3 sees the Sea Hornet on the sea at Southsea just after the start of the Round Britain Race in 2008. The receiver battery failed and a very nice Lifeboat Man from Southsea happened to be watching me run the boat and rescued it when it stopped running. it was put in dry dock over this winter to be tidied up again after a couple of years constant use and photo 4 sees it with its 2 new screens, re-varnished and 2 new rubbing strake. it is powered by 2 Graupner Speed 600 motors, a Ripmax sea sprint watercooled speed controller and 2 x 3 blade prop shop props on 2 x light weight shafts. it is also filled with bouyancy foam it case the inevitable happens which makes it quite heavy. it is ran on 2 x 8.4 volts nicad sticks and gives me a running time of approx. 20 minutes with quite a good turn of speed.

Hi" there, I like your sea hornet " You have done a brilliant restoration job on it 👍 . What was the last owner thinking of when he put that propshaft in and that hatch cover on the top 😯 ?
Anyway I have just bought one like this and looking forward in restoreing mine too !! Hopefully it should look as good as yours !
Albert .
this model was from the sixtys just got the hull and cabin
the cabin has been wired 12v it has an m f a 850 motor which
is water cooled just been tried once the speed controller
failed so try again ? will update as I go along
