    (Pleasure Craft) Precedent Huntsman 34"
    I bought it with a Merco 40/electric starter/radio as an unfinished boat. Changing over the brushless electric. (Motor: 3648-1450kv) (ESC: Hobbyking 100A car) (5/10)
    (Fire Boat) Vosper Crash Tender
    I bought it cheap and in good condition, but with no running, driveline brushes required replacing, a repaint of the deck and uppers and rewire the lights. (Motor: L5055C-700kv) (ESC: Hobbyking car ESC 100A) (8/10)
    (Racing Boat) Blue Vee
    40 year old fibreglass hull finally finished. Using it for testing motors and props. (Motor: 3639-1100kv) (ESC: Hobbyking 60A car) (6/10)
    (Racing Boat) White Vee
    Venom Ocean Racer converted from brush to brushless motor. ABS hull. Turned a lemon into very fast boat. (Motor: 3648-1450kv) (ESC: Hobbyking 60A car) (7/10)
    (Racing Boat) No name
    Plywood frame and skinned with balsa. Three coats of fibreglass resin on the outside and one coat inside. Hobbyking F1 outboard. Shelfed the boat after a number of 3mm flex drive breaks and the hobby store double the price of the replacement ones. Will change to inboard with the same motor, but with a 4mm flex drive setup, also replace the deck and cockpit. (Motor: 3000kv OUTBOARD) (ESC: Hobbyking 60A car) (8/10)
    (Pleasure Craft) Aerokits Sea Hornet
    Building from the original plans(25 and 1/4 inch). One piece plastic windscreens, customized engine and rear deck opening. Planking the deck with 5mm blackwood and 3mm Huon pine veneer at present. After 2 years running, a rebuild, the prop is 32mm 1.4 pitch 2 blade brass and clocked at 45 KMH. I only run on 3S but can run on 4S, it's a sleeper at low speed and a rocket on throttle. (Motor: B28-57-15L) (ESC: Hobbyking 6oA car) (8/10)

    πŸ“ Revering a servo’s travel with soldering
    3 days ago by canabus ( Midshipman)
    Flag
    I was asked the other day if I would do a β€œhow too” on how to reverse the travel of a servo. This probably doesn’t have a lot of need in model boats, as it’s not often more than 1 servo (generally the rudder) are employed. However, I am currently building a Shannon class lifeboat with 6 servos and 2 of them required to travel in the same direction for operating the reverse thruster buckets and twin trim tabs.

    1. Take the base of the servo off by removing the 4 screws.
    2. The 2 wires (orange) on the base of the servo motor need to be de-soldered and re-soldered on the opposite side. I marked one wire with a black marker for ease of identity.
    3.carefully remove the hot glue off the 3 wires soldered to the potentiometer. There are 3 wires, red orange and white on this corona servo, simply de-solder and reverse the red and white wires, the orange centre wire is left alone.
    4. Carefully put a small blob of hot glue or epoxy over the wires to prevent a short circuit happening.
    5. Reassemble servo and voila, should now be operating in reverse! Saves buying a servo reverser! Any questions, please ask πŸ‘

    I just reversed the two outer wires on the pot inside the transmitter it was far easier !!!

    Just pick up a Veron Police Launch with plans in a lot of 22 boats, 14 plans and a big box of bits.
    Only requires a bit of paint touch up, radio, battery and ESC.
    Also repair the searchlight base.

    HI All
    Some brush rock crawler motor specs:-
    Voltage 7.2 and all rpm's unloaded.
    35 Turn 13,000
    45 Turn 9,500
    55 Turn 7,700
    65 Turn 5,500

    If you divide the voltage by rpm, you will get a brushless KV rating.
    e.g. 5,500 divided by 7.2 equals about 750KV.

    Props (Raboesch)
    Type D :- 35mm max rpm 10,000
    40mm max rpm 8,800
    45mm max rpm 7,800
    50mm max rpm 7,000
    55mm max rpm 6,400
    60mm max rpm 5,800
    ESC I use the Hobbywing Quicrun 60 Amp for 2-3S lipo.

    These have link set up for Lipo and NIMH batteries.

    The other link is for Foward/Brake/Reverse.
    On boats set to Forward/ Reverse.
    This is the only ESC I found that goes straight from Forward into Reverse !!!!

    The MFA Motor Data Table shows the 950D2.51 at 2329 rpm on 6 volts (unloaded) and the 950D61 at 1941 rpm on 12 volts and 971 rpm on 6 volts.
    The motor in all cases with the MFA range use a standard RE-385 brush motor rated at 11646 rpm at 12 volts(unloaded). Both would easily turn that prop.

    Hi Lads
    After crawling the web, I finally found specs on crawler 540 motors on 7.2 volts unloaded.
    20 turn 13000 rpm
    27 turn 15000 rpm
    35 turn 12500 rpm
    45 turn 9500 rpm
    55 turn 7700 rpm
    65 turn 7000 rpm
    80 turn 5500 rpm

    The last three easily run 14-20 pound weight boats with 3-4 blade 50 to 60 mm props.
    I am using the 55 and 65 turn in Helen fishing boats and the 80 turn in a tug boat.
    No cooling on the motors !!

    If you require a faster motor a 3648-1450kv is a straight change over with all the other bits the same.
    Also you can change the battery to 4S and it will be a rocket.

    Hi Guys
    If you use the 3639-1100kv(800 Watts), you can straight change over to a 3648-1450kv(1600 Watts).

    So starting with the 1100kv
    3s=12,210 rpm
    4S=16,280 rpm

    The 1450kv
    3S=16,095 rpm
    4S= 21,460rpm

    Only double the power and 5,000 rpm more!!!!
    And the 1450kv can handle 6S, if you are brave !!!!!

    For that size model I use a Hobbyking 3639-1100kv brushless motor or a D3548/4 1100kv on a 3S lipo battery(between 3700-5800mah), a 60 or 100Amp car ESC (HK-60A-SL or HK-100A), program card(HK PROG-CARD).
    I have a good setup for this system, if you require.

    Prop start with the one you have, but I use a 2 blade 40mm or 3 Blade 37mm (brass or CNC).

    Slightly over scale speed, depending on the boat.

    2 years ago by canabus ( Midshipman)
    Flag
    Hi All
    The boat had the rudder completely vertical to start with and that is the problem.
    With the rudder vertical the boat pulls the bow down in the turns which makes it sit up on the chine.
    A planning hull attack angle is about four degrees to the water, but these boats like an angle of about six degrees.
    The leading edge of the rudder and the angle of it governs bow lift or dip in the turns.
    Also the balance point of the boat is as important as the rudder setup.

    Hi
    A few pics of my modify setup, no pics before hand.
    Moving weight fore or adding ballast works better than wedges.
    Only tested the boat by myself and I gave it a real workout.
    Motor 3639-1100kv, 60A ESC, 5800mah Lipo and 37mm 3blade prop.
    A 40mm 2blade works better and uses a bit less power.
    Rudder blade size 30mm across the top, 22mm across the bottom, 45 deep and the shaft 10mm from the leading edge.
    Sharpen the leading edge and the trialing edge flat.
    This catches are air in the water and send it to the surface.

    If you require a brush ESC.
    The Hobbyking one is the only one I have found with straight forward/ reverse with NO BRAKE.
    Set is with links, but the they only work on Nicads and Lipo batteries.
    They will run on 12 volt SLA, but no less!!!!
    I am using them in my two Hellen fishing boats with 55 turn rock crawler motors on 2S Lipo on 60% throttle.

    The sister motor is a 3639-750kv 600Watts 8325 rpm on 3S.
    The 3639-1100kv 800Watts 12210 rpm on 3S.
    Next up the 3648-1450kv 1600Watts 16095 rpm on 3S.
    All are straight bolt replacement, but, the 3648 requires a 100Amp ESC.

    The 3639 750kv would be the better motor for the boat to get scale speed.

    Hi Charlie
    I have tested my 37" Perkasa with a brushless 3639-1100kv motor from Hobbyking, a 60A ESC, 3S 5800MAH Lipo battery and 37mm 3 blade CNC prop.
    It's dam fast !!!!

    Hi
    Can we have a full picture of the rudder please.
    I was going to angle the rudder back to get the bow to stay up in the turns.
    We did this on tunnel hull boats years ago.
