S 100 Schnellboot RC build by kmbcsecretary Admiral   Posted: 4 days ago
Hi Doug yes I did try the three prop set up first MFA 385's if I remember correctly running on a electronize 30 speed controler.but replaced them with a Graupner eco 500 I think ?

It's a sad day!. by Novagsi0 Captain   Posted: 11 days ago
True Bloke. (thanks!!) The huntsman is my passion the boat above is a larger scale Sordsman 15cc. I sailed this last night as a ode to my father on what would have been his birthday we started this 30 years ago only finished in the last few months ready for the 14-May. wish it could have been IC but a large 850MFA gets it plaining (just), for an hour on lipo's instead. My father use to run FIA Rossi engines on gear boxes and do NAVIGA speed I think it was called. But there is a draw of ED Hunters, ED racers, diesel engines, Basil Miles Engines etc.

Additional supression added. by Novagsi0 Captain   Posted: 17 days ago
Following on from comments here and a mail from Como MFA i've added a 0.22uF Cap to the motor terminals. Hopefully that will see the back of the uncontrolled mounting the side of the pool disasters.

More running in at Bournville. by Novagsi0 Captain   Posted: 17 days ago
Update from MFA Como The motors, as they are, sufficiently comply with CE regulations for electrical emissions. However, sometimes with radio control you may need the extra suppression to stop radio interference. Initially try one capacitor across the terminals, this is usually a 0.22uf.

More running in at Bournville. by RNinMunich Fleet Admiral!   Posted: 17 days ago
I had understood that this was an 'old motor'. Could have meant decades! Quote: "old Brushed motors MFA850" But an extra .047 across the terminals won't hurt. Re: Fail Safe; a common problem as 99% of sets are pre-programmed for the Fly boys. First thing I do with a new set is delete all the presets for fixed wing / Heli and reprogramme to do what I want and on the stick, switch or knob that I want. Throttle Fail Safe on a plane is often equivalent to throttle stick right back since plane ESCs don't go in reverse the motor just stops. Can have some interesting effects on a boat ESC with reverse though !!!😲 Happy Trialling 😎

MFA 850 motor by Novagsi0 Captain   Posted: 18 days ago
On closer inspection of the MFA850 motor I can see 2 caps in side the motor connected between the terminals and the motor body / can. The only thing I can add is an additional capacitor of 0.047uF connected between the terminals as belt and braces. Otherwise move the aerial and hope no more paint accidents happen.

More running in at Bournville. by RNinMunich Fleet Admiral!   Posted: 19 days ago
Hi, I don't believe the motor has internal suppression! I have the full motor spec from MFA/Como drills and there is no mention of it. Would be most unusual. https://www. style='background-color:yellow;'>

More running in at Bournville. by Novagsi0 Captain   Posted: 19 days ago
I thought that initially, but apparently the MFA 850 has suppression built into the motor internal already, so no need to add any external caps according to google. I think Dennis is more to blame.

First run for 2018 by Novagsi0 Captain   Posted: 1 month ago
It wasn't my best video because of trying to do it my self and control the model. I will try again after moving the motor back a bit. Few people perhaps interested in the performance of these old Brushed motors MFA850 so I will do it.

Renovating my Aerokits Patrol Torpedo Boat. by BOATSHED Fleet Admiral!   Posted: 2 months ago
You say the MFA motor was strong but slow ?? Have you tried changing the prop and trying different sizes. I put a 4 bladed on a small version of a Crash Tender that I have built and it was a failure, I have since changed it to a smaller 3 bladed prop and it is better but now have 3 different sizes to change to and see if they perform better. I know they are not cheap., all 3 came to just over £35 but the first one I tried made a very big difference. You could even try smaller nylon props as they are a lot cheaper. I know they do not look authentic but when on the water they cannot be seen. If you have her on display at home you can always change the prop back to the nice brass one just for show.

Fairmount Alpine - TUG! by thepirate Sub-Lieutenant   Posted: 2 months ago

Aerokits Solent Lifeboat by olly49 Chief Petty Officer   Posted: 2 months ago
I have a problem with choosing the motors for this boat. The lifeboat I built in the early eighties and upto today it had 2 x Deceperms fitted(6volt). One of these now as developed a fault and it is far too expensive to buy a new one,soI have decided to go down the route of fitting a couple of MFA850's only to discover that these love the amps and thus could burn my P94 ESC. I would like to stay on the brushed side as I have the techobots sound generatormand this connects to the P94. So which motors should I choose?

Renovating my Aerokits Patrol Torpedo Boat. by MouldBuilder Lieutenant   Posted: 2 months ago
I built this Aerokits Patrol Torpedo boat over about ten years and finished, as I found painted under one of the life rafts, in 1993. I sailed it at my local pond and all went very well. The only problem I had was the speed. It was quite slow. The MFA brushed motor was strong but slow. I have received a lot of help so far on this site for which I am grateful. I have decided to do a complete renovation which is scheduled to be completed whenever. I work all day so can only spend limited time doing this. We will see how it goes. I must admit that I am not too concerned with the result being authentic to the prototype. If it looks good and I like it, that`s good. Sorry if you like things to be perfect to the original. If you see something I plan to do which you feel can be tackled differently, please shout. I may not always follow advice but I will always listen. I have attached a few pictures of the boat as it is for reference. It`s still not too bad for 35 years old. Just in case you notice, I have no idea as to why I thought it was a good idea to block the Captains view with a gun tub.😱 I will be stripping the deck back to bare bones soon so will post more soon. Thanks for looking and in advance for all the help that I am sure is just around the corner😊

Cabin roof mechanism by BOATSHED Fleet Admiral!   Posted: 2 months ago
I still have a 34" Raf crash tender still unbuilt that I bought back in 1994 when they released a run of 50 on the 50th anniversary of the model in the Model Boats magazine. I also have a Vosper 46” RAF Crash Tender Kit By Vintage Model Works sitting in my shed. One day I will get around to building them Along with restoring my Sea Hornet, Sea Commander, Sea Queen and my Huntsman along with several other boats, including an MFA Spearfish and a Stratos Interceptor, Hydrofibre Pipedream both of which were the same company just that they had a change of name. Along with at least 3 others. I will do them sometime.
