A few pics of my partly scratch build RTTL from Kitshack. Picked this up from Ebay as a first kit.
Has a few printed balsa hullparts but lots of templates to cut out. Plans also show lots of topside details.
Powered orignally by 2 MFA 500's and 2 7.2 NiMH with 35mm props, OK but run time poor.
Complete change, 2 400's and downsized to 25mm props, much better run time and good on the plane.
Next upgrade is to LiPo batteries.
Next build is likely to be an Aerokits Sea Hornet or Sea Breeze.

Really fine looking model. The detail really adds to the finished model.
Glad to hear you have chosen to go for smaller motors and props. The weight saving will really have improved the performance, and LiPos will make it sparkle. if your ESC(s) do not have some sort of cut off for low volts I suggest you fit a warning device to the LiPo to prevent over discharge.
Be good to see the model running on the water!

Indeed Dave, charger, batteries, alarms and charging bag on order!!
Sadly although my ESC's (tamiya TBLE02's) are Lipo compatible research says their cut off limit may be too low so fitting the alarms too as a fail safe.
hoping to get some video once its running consistently.

This looks very similar to mine. I bought it as a damaged boat and it will undergo restoration also with two brushless motors etc. it should be quite fast as I imagine yours is. However it will probably be mid 2016 before its completed as my new workshop is yet to be completed and all my boats are in storage> 😟 😯

Following burning out the motor by fouling the prop on a polythene bread wrapper I fitted a new 160 amp speed controller and got a bargain motor from Giant Shark. it is an Emax GT4020 which cost about £14. I realised what a bargain it was and went back only to find Giant Shark have ceased trading. The video shows the boat running on a 4 cell Lipo, it goes a bit quicker on a 5 cell that I have. I am really sold on Lipo power as Dave said I would be. I have just ordered a 3 cell Lipo for my crash tender

This is my M.F.A Tracker . When originally purchased it had the large and heavy 850 motors in it and old electronics , after a close call with a fire on board I decided to refit her out with modern Brushless motors and over rated Escs powered by Lipo's . Works out a 1/3 rd the weight 3 times the speed and run time over an hour . So a great result
Oh yes , sound effects donated by nearby Tug 😊

This video follows on from my earlier post. I changed to running on a 5 cell lipo (18.5 volts) and I am very pleased with the Improvement over 14.4 volts Nicads. (Edit sorry Nimh`s) I put this link into my reply on my previous post but it didnt work as a hotlink so I am posting this.
The boat isnt quite flat out here due to the difficulty videoing and steering.

HI Les
What a bummer. Bread is not good for wildlife and certainly not for props.
Hopefully your motor should be OK as long as the wires are not burnt. if you have a multimeter you could check the insulation between the shaft and each winding using the highest ohms reading. it should be high, if low chances are there is an internal short. A quick check (on a lower ohm reading) between windings should give similar results between every pair, again any variance may indicate an internal short.

I am just building one of these on a wood hull, I notice you are running a single motor. Could you advise what motor you are using plus what prop please? Thanks Andy

I think with two beefy out runners, 42mm props on 14.8 lipos it should be a very powerful boat. However I like big boats properly engineered. Well done. 😀

Glad to hear you have chosen to go for smaller motors and props. The weight saving will really have improved the performance, and LiPos will make it sparkle. if your ESC(s) do not have some sort of cut off for low volts I suggest you fit a warning device to the LiPo to prevent over discharge.

Sadly although my ESC's (tamiya TBLE02's) are Lipo compatible research says their cut off limit may be too low so fitting the alarms too as a fail safe.
