Hi 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. Canabus
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. Canabus
Hi All I have finally fix the boats turning problems by racking the rudder forward 8 degrees and making a new rudder blade with the leading edge straight. The bow only dips slightly on the turns. Canabus
Hi All 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. Canabus
Hi All 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. https://hobbyking.com/en_us/hobbywing-quicrun-60a-2s-3s-wate... Canabus
Hi All I use the Hobbyking car ESC's HK-45A, HK-60A SL and HK-100A which all use the same program card(HK PROG-CARD). 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 4 Run Mode=2 5 Brake Force=1 6 Drag Brake Force=1 7 Neutral Range=1 8 Initial Brake Force=1 9 Reverse Force=1 It works for me.

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. Canabus
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 !!!! https://www.youtube.com/watch?v=9fddqnbnlrQ Canabus
Hi I am working on a Precedent Perkasa 37" and I added two sets of double 10mm magnets to the front of the wheelhouse and one set at the stern. I can lift the whole boat with battery by the wheelhouse. I do not think it's going to come off !!! Canabus
Hi Sandgrounder There are a number of speed 400's with voltage range from 4.8 to 7.2 volts. The revs range is between 16,400 to 22,000 rpm. So 28mm brushless like a Prop Drive V2 2836- 1800kv(shaft 3.175mm) on a 3S Lipo battery with give you 19,980 rpm. ESC 45Amp. Prop 30-32mm 2 blade. If it's tight of battery space Hobbyking have small ones you can parallel together like the Turnigy 3S 1500mah 25C (73 x 33 x 27 mm). Regards Canabus
Hi All Installed the deck and filled around the edges. Gave the hull a quick run and it handle very well. Good turning circle and at 50% throttle still over scale speed. 3/4 throttle looks about right. About to start planking. Canabus
Hi All Installed the rudder with oiler, also installed the 60 turn motor with metal joint from banggood. Installed the 4.5KG servo with linkage to the rudder. First coat of Matt 37 which showed up a few spots that require a bit of filling. Canabus
Hi All Finished the dingy, hatch, skylights and companion way. Added some paint, matt 131 green for the hull, under water the hull is matt37. Yellow for the trim bits with matt vanish for the wood work. Canabus
Hi Steve I started with the Hobbyking 3639-1100 kv in my Huntsman with a 2 blade 40mm prop, 3S 5800mah Lipo and a car 60 Amp ESC. Upgraded to the 100Amp car ESC and a straight change over to the 3648-1450 motor. All from Hobbyking. Good units and have no problems. Also a the price will not break the bank book!!! Note, change the uni-joint to metal as the plastic ones will not handle the power and break. Canabus
