Brushless Equivalents by Haverlock Fleet Admiral!   Posted: 3 days ago
IC to electric conversion table IC to brushless ( for aircraft but its better than nothing) Hope its some help

1940 Chris Craft by canabus Fleet Admiral!   Posted: 4 days ago
Hi All I have started on a 1949 Chris Craft Runabout as I bought the started kit for a good price. Drop out all the motor and 1/8" shaft. Installing a 4mm shaft and a 28mm brushless motor. As I have all the frame patterns etc. I could easily make the 1940 one as only the rear would require modifying. Canabus

Brushless Equivalents by canabus Fleet Admiral!   Posted: 4 days ago
Hi Andy I work on the motor case around the same size as the prop diameter, the rpm and power of the old motor. Add a few more rpm as we like to go faster. Matching the revs from the old motor e.g. 20,000. Kv of the brushless motor times the Lipo Battery cell number(4S= 14.8 volts) e.g. 1450kv times 14.8= 21460 rpm. So an OS40FSR was 1.6HP @ 20,000. Replacement 3648-1450kv = 21460rpm(no load). Power 750 watts = 1HP and the 3648-1450kv is 1600watts. As for brushless to brush motors you can match the rpm, but, the brushless are far more powerful than the brush motors. As for a conversion chart it would be a big task and some of the gear is not available in all countries. Canabus

Brushless Equivalents by AndyG009 Lieutenant   Posted: 4 days ago
Possibly the wrong title - but. Has anyone produced a conversion chart: Non-Brushless motor types to Brushless (for different manufacturers) Glow / Diesel motors to Brushless If not. Does not need to be exact, but I am sure that there a many out there that have replaced or know what was originally intended to be fitted is a particular boat, and have replaced it with a brushless. If enough people contribute - I will create a table.

brushless motor by Mataroa Fleet Admiral!   Posted: 5 days ago
Hi canabus would you let me know how ur trials go with brushless motor and with 100AMP esc and Lipo battery. then i get the same for my boat .many thanks for the help .cliff

nearly there by Northumbrian Fleet Admiral!   Posted: 5 days ago
just about finished only a few deck fittings to add i used a brushless 1700kv motor & 70amp esc it runs well on a 3 cell 5000 mah lipo the planking is made from old wooden blinds the only outlay was for the motor & esc the rest i had it is marvelous what you collect over the years my next build will be an airboat i have found a motor from a WOT 4 airplane 😉

brushless motor by canabus Fleet Admiral!   Posted: 5 days ago
Hi Cliff I am installing a Hobbyking Turnigy L5055-700(1600 Watts) with a 100Amp ESC and a 4S 5800mah 60C Lipo battery. Plan to start with a 2 blade 52mm CNC prop. Canabus

brushless motor by Mataroa Fleet Admiral!   Posted: 6 days ago
Hi i have 46" RAF Crash Tende im look for brushless motor i know i ask this be for but i forgot what type of brushless motor that i can use .can any one help . Many Thanks Cliff

Motor size advice by canabus Fleet Admiral!   Posted: 8 days ago
Hi Morkullen I suggest a Hobbyking 3639-1100kv 35mm brushless motor with a 60 Amp ESC and a 2 blade 40mm prop. Battery a 3S Lipo 5800mah 25C will give you more than 1/2 hour. I had his setup in my 34" Sea commander with very good performance. Canabus

MTB379 by wunwinglo Lieutenant   Posted: 10 days ago
[Score: 5/10] 39" MTB379 Capable of 14mph Twin Propellors (3 Blade 45mm) Direct Drive Powered by LiPoly (7.4v) Batteries - Comments: This model was originally built by my father in the 50's for i.c. power. It was laid up in 1962 and remained inactive until two years ago. At that point, I egan recommissioning it, fitting twin brushless motors in place of the deafening single glow motor and straight-cut gears. I also added a great deal detail that my dad had never added. It performs very well nicely in this guise with the added drama of a throttle-linked digital sound system.

It's a sad day!. by wunwinglo Lieutenant   Posted: 12 days ago
I can well imagine how you feel about your i.c. models. My recent renovation/recommissioning of my late father's Vosper MTB is kind of ironic in that it last ran in 1962 when noise suddenly became an issue. Mind you, it was VERY loud. My rebuild, needless to say, was centred around brushless motors and lipo's. But I also put an excellent sound system into it as it was so quiet. The system, by Action Electronics and is nice and loud as per the full-size but it does seem ironic that I felt the need to put sound(noise) back in! I use lots of small diesels in free-flight model aircraft and still hugely enjoy getting them 'singing' and savouring the wonderful smell in the car going home afterwards!

It's a sad day!. by canabus Fleet Admiral!   Posted: 14 days ago
Hi Stormin I think it's the same in a number of countries. We changed to brushless and Lipo's. All my IC motors are in a draw sleeping

It's a sad day!. by stormin Sub-Lieutenant   Posted: 14 days ago
Yes I've decided to sell most of my I.C. Boats and engine, because of this "nanny state" that we live in now. Probably 95% of clubs and sailing waters in my area(Liverpool) stipulate No I.C.s, l'm not traveling 50 miles to sail when in reality I've got several clubs and lakes within 5 to 10 miles from my home. I started model boat building in the 50s with balsa models and on to "aerokits" sea urchin, scout, rover, commander, and the holy grail the sea queen all of which had diesel or petrol engines. Granted we have come a long long way since then with electric and brushless motors, I do use them in both planes and boats, but there is still something to be said for the sound smell and reality of an I.C.engine in a boat, aircraft aren't to bad at the present, until they ban them to. Sorry for the rant but that's the way I feel.😭

Sea Commander restoration tips by canabus Fleet Admiral!   Posted: 20 days ago
Hi Laurence-Moar MY Sea Commander had a brushless 3639-1100kv motor on 3S 5800mah Lipo battery with a 60 Amp ESC and a 40mm 2 blade CNC prop. Very good setup, a bit over scale speed. Run time a half hour flat-out. The boat runs better with a bit of bow down sitting still in the water. The battery position about aft of frame B3. I swap my boat for a nice fishing boat( Artesania Latina HELLEN). Canabus

Vintage Aerokits Fire Boat by rolfman2000 Fleet Admiral!   Posted: 21 days ago
It's nice to see vintage Fireboats running anytime. But running with original motors is unusual, and makes this even nicer. Thanks for sharing, as I am halfway through a rebuild of an original Aerokits boat as well. I think mine had a 10cc glow in, but not for long, as its not full of goo like some are. Im putting an equivalent brushless motor in, and hope to have it wet by the end of summer. Best wishes, Dave W 😊
