    Well it was a struggle, but I have gotten S91 to operational…there is still details to be added as in weathering and paint …but I am happy with the over all build .
    I ended up removing one of the three motors due to weight concerns and better use of the space it would give as to both operations and maintenance. I may revisit the motors and ESC’s due to having to dial back via the transmitter to 20% of full power , any more it starts to get very unmanageable and unstable.

    Spent the last couple of days and a few dollars repairing and rebuilding the main propulsion , as the new 85 Amp ESC’s are a bit heavier and larger than the 45 Amp ESC’s they replaced I opted to remove one of the 3 motors. This will save weight and provide space to get better air flow and still give a 1/3 more power over the S100 build 2 - 2218kv vs. 3 - 1100 kv motors .
    I have again successfully performed both bench test and a tub trim test of all systems/ channels and now await a trip to the pond for a full shake down ….As much as I enjoy building it breaks my heart that I no longer have the hands to do the fine work skills I once had , I continue nevertheless……

    The good news is my S100 and the Two Vospers ran with out issues, so with recharged batteries I look forward to the next meet sailing meet….

    The S91 not so well ….I am lucky that with quick action it appears the damage is easily fixed ,like all things mechanical , time and money …and most importantly education and learning …The photo says it all ….😞

    I am not sure but it looks like It was a number of factors , from not enough ventilation, to not enough big enough Amperage of the ESC’s …along with the possibility of the props not correctly matched to the motor size …my solution has been larger ESC’s …85 Amp vs. 45 Amp …motors are rated at 40 Amps …but no spike/ peak data available…I have added Fans to the ESC’s and opened the deck for better air flow. Given The larger ESC’s , I removed one motor and ESC …to save weight and to gain space for wiring and air flow …This still gives me 1/3 more power over my first EBoat build of a S100 , see Blog …2- 2218 kv motors vs 3 1100 kv motors .

    I am still not sure what/ why I had this failure , but I am correcting many possibles , , 1. Not enough ventilation, and possible heat build up .
    2. Not enough over spec in matching an ESC to the brushless motor ,,ESC 45 amps , Motor 40 Amp …
    3. Component failure in the ESC , …
    4. To large , or to great of pitch of the props for the motors , …S100 has 3 discontinued brushed motors and ESC ‘s and ran well from day 1 ..bought over 6 years ago , otherwise I would have bought the same set up again .

    My current efforts are focused on more ventilation, and a larger ESC at 85 Amp , as such , I am removing the center motor and only powering with two counter rotational props of the outer shafts .along with a prop change in the future if needed. In the mean time I wait for the electronics to finish drying out for so far they all work after being dunked to put out the flaming ESC , the deck did get some damage from the flame…but fixable …the addition of floatation on the removable hatch over the motors and ESC ‘s took a large part of the flame damage before the deck hatch and Hull did .

    The removal of the center Motor and it’s ESC will lighten the load and give me space to better run the wiring , ….I feel the major mistake I made was not taking into full account the peak or spike loads.

    Well with help from the local Hobby shop that is more into RC cars and off road I was able to learn what I should have remembered from my youth and education and work experience…..We are close this is a bench test just before a sea trial 🤔. Must have missed a button or two on this post …will keep trying to get the video to work or maybe I have fixed it time will tell ..

    Still don’t know why but at this point I am just taking it as a near miss, I went to the only source I have locally for information about Brushless motors , ESC’s and Lipo battery packs . It is primarily RC Cars , Trucks and Off road buggies…..very very little in the way of boating , understandable as to the limited ponds and water ways that have access, it’s even the same for full size boating at least for fresh water ,,,Salt water well that’s always been $$$$$.
    Still don’t understand what was done , rewired everything the same way I had it in the boat back at the apartment, ….except it all worked ….No factory smoke released….Motors and speed control worked as it should …now a day later , and everything back in the boat , I and ready for finial trim and sea trials , ….

    🤔. I just done know ..but I will take it …the next club meet is in July …and my fleet will be in top form and will be out on the water …

    Be Safe and Smooth sailing

    📝 Vosper after action reports

    Well not checking before rushing off to the meet was my major mistake , my St Nazaire special , had a collet set screw that missed thread lock resulting in the loose prop shaft . I also found a few mounts that had not been glued in place well enough so fixed a possible future failure,….she is now ready to run .
    My standard Vosper , had the suspected grease issue , along with a collet that was to tight running against the end of the prop shaft tube , this added drag and heated the motor which resulted in the bridge deck to start to melt . Not realizing that my deck fitted that close to my motor mount as it heated an melted it then contracted the motor adding more drag ,..more heat ….this also explains the change in sound during its short run as told to me by my son. Final failure was the motor ripping out of it mounting and binding the works up ….

    I have fixed all the issues found ,hopefully this will help others too not make my mistakes and let the enthusiasm over ride better judgement and practice…

    Back in the water!
    Bill G.

    P.S.
    Still evaluating the S91….😖

    I agree , I really liked these conversion builds ,unlike the S91 project that has a displacement type hull , these plane hulls require a light touch I feel so have been given a small brushless helicopter motor I felt it was a good fit and I am happy with the out come and their performance. As long as I have done my part ….lol.

    Your Vosper puts my feeble efforts to shame that is a fine looking model. Very Nice !!

    Hoped to get an early start to this new to me Marine Modelers club based in Boston Mass. but members from all over the state and near by. …Well I loaded up my Two Vospers , check out their build blog , …and the still on going old lindberg Blue Devil Fletcher class destroyer and arrived two hours after the start time , took a quick look at some fine scale models and the paperwork to become a member . After answering many interested questions as to my builds and the models I had brought I sent out my St. Nazaire Vosper ….Only to run it into the biggest patch of weeds and have my driveshaft fail🤦‍♂️. So had the pleasure of one of the members wade out and retrieve my wreck ….Ok …Things happen no biggie will just send the other Vosper out …Handed the model and controller to my son and he took her out …for about 3 minutes only to have it go dead in the water …with a locked Prop Shaft ….😖😖😖 have yet to open the hull up to see why …but have a feeling the home made prop shaft did not get enough grease and not checking it in my rush to this event only put frosting on my cake as the new guy. 😞🤦‍♂️. Good news is I had Video of my runs from last year and the over all results is that several members are ordering kits to convert . A good day!
    Back to the bench and repairs …😊👍

    Commiserations my friend, similar happened to me as well last Wednesday. Took the Orca for a quick sail after club meeting to find she would only go around in circles-of course this only happens when you're far from the shore😂 rescued by feĺlows and find the steering linkage was broken.
    Easy fix, test bench afterwards only for the esc to suddenly start smoking and in turn cook the battery .. hey ho, hopefully you'll get yours sorted and I'll get started on dismantling 🙄.

    It been awhile since my last update , but life is like that at times we cant always do what we want or even feel up to doing it …lol I have started to move forward to getting this to be a runner , by working on a few details and mounting hardware , running the wires and ordering bits and pieces that are needed. I have done a quick water line check and trim with more weight than what is currently required as to known parts that must still be installed . She is looking to be a bit light or very close to spec as to draft and still have room for more battery or details . I can’t wait to see and hear the sound board and muzzle flash in action…And I seemed to have new help …lol …Be Safe All

    Well things are progressing slow , life does that at times , tho a bit of procrastination can be made if honest …lol ..I have done more detailed work and finalizing things as to hull access , and component mounting/ locations …one thing I have added that was not on my original build plan is a sound board and LED muzzle flash .
    I am very excited to get this in and see and hear it on the water . My only regret is where I am adding muzzle flash to the 40mm Bofors in the stern that I have reto fitted the LED . I feel if I had installed it at its build time I could have run the fine wiring better , but we do the best we can . What is nice is that the sound board has proportional Throttle Diesel engines, 20 mm bust , 40 mm Bofors bust and Torpedo launch ,with warning siren ,…as an added feature the LED out puts for the engine’s exhaust, and the weapons are synchronized to the sound of each , so you can have exhaust flash , and muzzle flash when the sound for each is activated.
    Hope all are well , Good Building and Best to All

    I found Model Sounds inc. online , they have a wide selection of sounds and for a small fee can customize your sounds and has the option to purchase software to make your own customized sounds . Their system can be optimized to be removable and placed in different models. I have found them to be very helpful and worth the consideration when choosing to add a sound system .
