📝 Revering a servo’s travel with soldering
3 days ago by canabus ( Midshipman)
Midshipman)
I was asked the other day if I would do a “how 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 👍
I just reversed the two outer wires on the pot inside the transmitter it was far easier !!!

Hi Uncle T
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.
We are not in lockdown so it will in the water very soon.
Funny the local police station was sold and is now a pub .
PADDY WAGON !!!!

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 !!!!

Hi All
I have three Eileen/Hellen fishing boats running 540 Rock Crawler 80 turn brush motors on 7.2 volt Lipo batteries turn a 60mm 3blade prop.
I have trimmed to throttle back to 60% because the boats were over speed !!!
The motors run with no cooling .

Hi
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.

I have my two 3S 4000mah Lipos mounted each side of the rudder.
That's the only way I got mine to turn better.
The boat is not great on the turns at the best.

I get my lead from Tyre shops for free out of their scrap bin.
If you tell them what you are going to use it for you generally get some.
Ask them to visit your club and bring their kids.

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 !!

Hi Bill
A Hobbyking 3639-1100kv 800Watt on a 3S 5800mah Lipo battery with a 100Amp ESC and for a prop 2 blade 40-45mm.
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.

I live in Hobart, so not to far away from you mate.
My mate and I both have Sea Hornets, his has a funny cabin on it also.
Mine is build by the original plans.
Brushless 28mm 1900kv, 45Amp ESC on 3S with a 32mm prop.
Was GPS at Lauderdale canal at 45KPH.
WE sail on a Saturday morning from 9 to 12, so if you are down this way call in.

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 !!!!!

Hi Bengtt
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.

I use 10mm magnets in a double setup, one mounted on the hull and one on the cabin on each corner of the cabin.
On my last Perkasa I used the double setup forward and a single double setup on the stern.
The total weight of the boat is six pounds and I can lift the boat by the cabin!!!

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.

I use silicon tap grease as it's waterproof and add a bit more after each outing.
Strip down, check for wear once a year and regrease.
Started using Teflon bearings for the lower bearing which are holding up to the brushless motors.

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.

I use the same setup for all my boat, only changing the battery setting for the 2s, 3S and 4S Lipo.
1 Cutoff Voltage for 3S=10.2 and 4S=13.6
2 Start Power Percent=5%
3 Advance Timing=4

Hi RHBaker
I had the motor ,so I used it.
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.
