Two years ago, while participating in one of our clubs events, A club member, and a friend, had gifted me a classic DUMAS Chris Craft Cobra. It was a welcome gift. Yet plagued with problems , right after another. It was basically broken out of the box, and marginally not safe to drive. IT plowed water, rode low, and was a death trap, when going into reverse. It would and flood, eventually sank. And almost two years later it was fished out by another club member, and took three weeks to restore. It became my daily driver 6 months ago, and is officially one of my best running boats. It become known as the "Phoenix," because it basically came back from the dead, and was returned as a much better boat. It's got some kiddy' up, and is 4S ready. ON 3 S. I'm skirting 30 MPH, from a 2000 KV. motor.
The build history is unknown. We don't know who the original builder was. Only that it changed owners at least 4 times. ME being 3 and 4. It was basically , the boat came back to me , after I was the one who lost in the first place . NOW, it's resting on my table, fully restored. THE photos , were of the restore process, and the first day back in the water.
I was there the day it visited Davy Jones Locker!
Super glad you got it back, and with the help of a talented fellow club member it was made sea worthy again!

I bought this boat in reasonable condition five years ago from an estate sale. The original geared 540 brushed motors were rusted beyond repair, so I replaced them with a pair of 2830 1000kv brushless motors, running off a pair of 6 cell NiMH packs.
I use a transmitter mix to allow the model to rotate on the spot and perform scale-like docking manoeuvres.
That's a nice bit of video. she runs well.
I have a Krick Outboard but still haven't decided as to what I am going to put it on yet. I have also got a Graupner Rhode Island F1 Tunnel Hull that has a brushless outboard on it but not had a chance to run it yet.
Scratch built motor gun boat from Bangladesh.
Tried my best to upgrade it into a brushless one. First attempt was brushed and it was kind of a pain in the ass.
It runs far better now.
Finally got a good day to try the new brushless motor. Boat goes 100% better now (if a bit noisier) 3s 25c 2200mAh liPo got a bit too hot, so probably need to up the C rate to 40 to keep it cooler (maybe install a fan as it's closed under the seat) It's pushing a 6lb boat with a 26mm jet with a 3000kV brushless so it has an excuse to get hot, (only got down to 3.7V/cell after that run, so not too bad). Runs with a more scale look now which is what I wanted. Took a bit of experimenting, but got there in the end. Thermostatic cooling fans for the motor worked well, and within 10 mins the motor was cool. Only used around 2/3 throttle so as not to stress the coupling too much (you can hear it protest a few times, - silicone tube slips slightly making it squeal)- automatic rev limiter😁
Sorry, vid is blurry again ☹️ (original's fine -HD) but something happens when it goes through my movie editor then to YT. Keep procrastinating about getting a better camera (or maybe it's just the editor. - More experimenting, this is getting tedious😐
Hi Ron, haven't spent a huge amount due to the fact that all the electrical bits are very cheap ($1 ea for a voltage reg, $8-12 for a pump, $30 ea for a motor (bought 2 as the first was not fast enough) and jet unit, $15 for the ESC, a few JST plugs and wire, $3 smoke pen, few lengths of silicone tube etc, plus balsa and f/glass, -probably not a lot more than NZ $200. A lot of things you buy of course like resin and paint, usually have to be bought in bigger quantities than you would use on one model, and may be used on other projects, so it's hard to work out an exact cost. I think the hull was the most expensive part, due to the cost of balsa and resin.
Mostly a lot of time, (hate to work out the labour cost on any model at going rates,- probably in the thousands)!
More changes, (not again you say😐) this time the original nozzle was re fitted, as I found that the very clever improvement I made, (a flasher, smaller, better fitting brass one), wasn't so clever after all (can't be brilliant all the time😁) and was restricting the flow. The performance was quite a bit better today (still not startling) and it seems obvious now that MORE POWER will be the next step (have a higher KV, 35 sized brushless coming on the sampan to try).
Had a chat with a long time expat UKer (ex British army) at the pond today, and he mentioned that he has an Aerokits fireboat 'kit' still in the box he hasn't started, (you might be able to hear the conversation) and that he was modelling in the 60s in the UK, running diesels in his boats. He was sailing a Kyosho Seawind today (as was the other guy),- and they look like a nice little yacht, and sail well.

This 'Whaleback' boat is a 1/16th scale Air Sea Rescue Launch that was built by a friend of mine Graham. It is powered by a Turnigy brushless motor and Lipo Battery
I thought it the most appropriate music for this RAF boat at speed. I too loved that film from the first time my Mum took me to see it at the Savoy cinema in Colombo, Ceylon (Sri Lanka) when it was first released in 1964.
💡Scratch built from plans. Plank on frame. Large brushless motor,150 amp esc,length is54 inches custom made propshaft ballraced at each end and middle. Has running lights,and large very bright searchlight. Flack Mats were made by better Half. Everything else was scratch built by myself.
