Title: My new 52" catamaran RC boat Diy Post by: desachristopher on June 03, 2017, 07:12:12 AM This is a 52" twin hull RC catamaran . Built with 3mm plywood. I used fevicol as a glue. But latter switch to araldite. Below are some build logs..(https://uploads.tapatalk-cdn.com/20170603/39c4ab5f8a3dc1b4a1e4a3b6592adcba.jpg)(https://uploads.tapatalk-cdn.com/20170603/f19b4e4469cf7a5b8e49509e7720e1c8.jpg)(https://uploads.tapatalk-cdn.com/20170603/9d6ec1a01000247ba870d7921c76b17d.jpg)(https://uploads.tapatalk-cdn.com/20170603/f31e39b3c5b526a8a2af096ad13d0bcf.jpg)(https://uploads.tapatalk-cdn.com/20170603/e4578e1a757616109e5a7f76cfe819d4.jpg)(https://uploads.tapatalk-cdn.com/20170603/70767ad9fde6a36fa478d4fe4240e374.jpg)

{:)} Must be far more difficult using ply as compared to balsa. Hope you are going to: 1. Have a thin fibreglass and epoxy finish, plus spray painted colours 2. A roaring nitro engine to make this cat really fly 3. Set an Indian speed record for boats Looking forward to completion...

Title: Re: My new 52" catamaran RC boat Diy Post by: K K Iyer on June 20, 2017, 08:41:56 PM Mr. Iyer. tomorrow I'll be painting, hope it comes good. Hope you have a good spray gun. Or that you are using spray cans. This boat deserves better than a brush job... Edit And you never told us about that high powered nitro engine... Title: Re: My new 52" catamaran RC boat Diy Post by: desachristopher on June 21, 2017, 02:51:32 PM I have a brushless set ready, thinking of going for a petrol engine. like brush cutters. hope I get one in local market/shops

Title: Re: My new 52" catamaran RC boat Diy Post by: madaquif on October 10, 2017, 01:23:08 AM what's the electronic setup of this monster ? ? ?
Title: Re: Post by: desachristopher on October 10, 2017, 06:18:47 AM Electronics are 3650 brush less motor. 180a ESC . 5000mah 4s lipo.
I only need to change the motor. Sets a motor on Ali express. 4090 size somewhere around 1200kv . I think it's for enough power to handle this boat. But very costly. In less then what it cost I can get an engine.

I watched the entire video log and can imagine your plight building this beauty. Loads of hard work, patience and perseverance, I must say. Yes, the boat is slow and you need a Bigger motor for it. I think it can go 4 times the current speed. If you going electric, do use the marine ESC with water cooling. Add a small diaphragm pump if the need be so for cooling. I am on a similar project with a 48 inch Stryker cat hull and a 26cc motor. I ain’t got those scratch building skills nor my patience lasts that long. Lol. Anyway, good luck and keep updating!

Open the hatch, place the engine in the engine bay and take a photo. Eager to see! (Is a bigger motor/esc/lipo much more expensive?) Regards |
