SRN3 by Gascoigne Lieutenant   Posted: 11 hours ago
A challenging project 10 years ago. Scratch built model of theSRN3 built under licence by the US for use in the Mekong delta against the VC in Vietnam. Very light construction with liteply. Two ESPs control brushed and brushless motors for lift and propulsion. Motor tube ball-raced at each end with a 9x6 pusher prop. Realistic performance and sounds like a turbo prop. Tricky to control in anything stronger than a light breeze. Best on water.

MTB385 & MTB623 by reilly4 Lieutenant   Posted: 2 days ago
Vosper 73ft Type 1 MTB - Scratchbuilt. Now running two brushless motors and NiMH batteries. Photos previously posted. 1/24 Scale Fairmile D MTB623 belongs to a good friend. This boat was also featured in a previous video with my Fairmile D. The lake was a bit choppy with realistic sea conditions.

Donation all done. And thank you all for your help. So glad I found this site 👍

Brushless motors by Dave M Fleet Admiral!   Posted: 3 days ago
Hi Spitfire Glad to hear that you will be supporting the site's running costs. Stephen (Fireboat) runs this free site entirely on donations so every little bit helps. Doug has answered your question re wiring the brushless motor to the ESC. I would just add that you should not swop any wires whilst the battery is connected. I would also advise that you fit a fuse between the main battery and the ESCs. Brushless motors can draw very heavy currents when stalled or overloaded. A fuse rated just above your running current and no more than 50% of your ESC rating. I am assuming here that your wiring is capable of carrying this current? If you haven't got one I suggest you purchase a wattmeter so you can measure the current drawn under load (hold the boat in water and run at full wack). This must not be greater than the Motor or ESC rating. A smaller prop will reduce the current. Please keep us posted

What is this boat ????? by canabus Admiral   Posted: 3 days ago
Hi Dave M Pics as required, one Sea Hornet 28mm brushless motor 1700kv, 3S Lipo 2650mah and a 2 blade 32mm prop. Canabus

HI Spitfire, As Dave M said, the only silly question is the one you didn't ask, usually an expensive answer!!!!!!! Mark

Yes Colin, in essence that's all a brushless motor is! Cheers Doug 😎 PS: How's KGV getting on? I'm still into Sea Scout and PT boat renovations / conversions. But I know what my next 'new build' is! See pics, 'undreds of bits an' pieces 🤔😉

Hi Doug, that's just like a 3 phase motor. Is it always like that for brushless motors.

Brushless motors by Spitfire99 Lieutenant   Posted: 4 days ago
Now that was easy. Can’t believe it Thanks Doug 🙂

Brushless motors by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi Spitfire, this is the easy bit 😉 it doesn't matter!! 👍 If you then find the motor runs backwards when you shove the stick forward then just swap over any two wires. Cheers Doug 😎

Can you help with this Dave on the ESC I have three wire to context to the motor Red Blue and Black. On the motor the wires are Orange Yellow and Blue. What goes where

Brushless motors by Spitfire99 Lieutenant   Posted: 4 days ago
Thanks Dave yes that’s what I was thinking. How much is this going to cost me if I get this wrong. New motors new ESC. Thanks for your help. Being as you have saved me, the cost is time and yours and others so I’m going to make a donation to the web site for up keep. That the lest I can do.

Brushless motors by Dave M Fleet Admiral!   Posted: 4 days ago
Hi Spitfire This is one of your brushless ESC's. As you have indicated the wire is the red one with a brown wire and yellow wire either side and the black bit is the plug. If you turn it over you will see the tab that I suggested lifting to remove the red wire and tape to the brown and yellow wires. The BEC is contained within the ESC and if you do not disconnect one you will encounter all kinds of trouble. Keep asking the questions we have all been there and mistakes can be costly.

Sorry that was thanks Colin
