    Sorry I failed to read your first reply properly,
    I have the 1/24 Hooben kit and have been trying to figure out how to propel the torps for ages, How did you activate the motors upon launching ?.
    Will try and locate a small helli motor and experiment. Could you provide any drawings / plans ?
    Thanks for your time

    Thanks for your response to my query
    Were they the original torps that came with the kit or did you make / print them from scratch.
    How did you seal the prop drive shaft ?

    Hi Roy
    Thanks for your in depth response, I have 3 x Planet T5's (2.4 Ghz) although usually only 2 are in use at the same time.
    The chargers I am currently using are Tronics as sold at Lidl and charge quite fast, however I believe they stop charging when a certain temperature is reached rather than voltage.
    As the charging cells get very warm in the process I use a fan to dissipate the heat and this lengthens the time taken to charge, which is why I am suspecting temp prioritises voltage.

    Not suggesting Doug dosn't give good advice or is nothing other than a skilled builder, but the way that post was written came across to me as I described.
    Is it such a problem if my boat wont run for more than 10 minuets at full steam, come on man how often do you imagine that scenario evolves, most of the time is spent gently cruising around the pond with the occasional full throttle run to wake up the old farts. Tut Tut such disgraceful behaviour.

    Wouldn't call a Precident Perkasa a quickbuild, runabout or ARTR even though there isn't much realistic detail involved, the Hooben however is another matter with every little detail reproduced with superb accuracy.
    Life is hard enough as it is why make it harder.
    You are coming across as a pretentious perfectionist who puts down others who don't subscribe to your personal ethos.
    Not all members are talented miniature marine engineers but still have the same enthusiasm for the hobby.
    No one should decry them for there lack of skill, if RTR, ARTR, quickbuild or runabout is the limit of there ability, so what !!, they still enjoy the hobby and that's what it is all about.
    There are many roads to travel before one reaches there destination and the route one takes is up to them !

    Don't quite understand why you would want to run four props & motors. One of my fleet is a old Precident Perkasa, in all wood including the hull. Powered by a 12v 7ah lead acid battery a single 550 motor and a three blade prop.
    As you can probably imagine she is heavy but still gets on the plane to mimic the real thing, will admit the motor did get a bit hot untill I fitted a heat sink with fan cooling.
    I also have a Hooben Perkasa in injection moulded plastic, yet to be built but intend to use the same set up.
    Cheers for now

    If its of any help I run a all wood Perkasa with one motor (came from a old battery power tool) powered with a lead acid 12 volt, so as you can imagine its heavy.

    But she will plane as per any photo you can find on the NET. ๐Ÿ˜Š

    You state that you are waiting for parts from HK, is your BB a Hooben model ?. I purchased one of these and found the moulding of the transom to be atrocious and the company's customer service to be non existent.

    I really cant believe this happened to you, any decent member of our community would never have treated you in such a disgusting way.
    Personally I run 4 boats on 3 x Planet 2.4g Transmitters all with brushed motors which all came from old cordless power tools and never had any problems.

    Hello shipmates.
    Well I finally managed to find and win on ebay a Hooben Perkasa that I so longed for.
    Why the Hooben rather than one of the others on the market ?, because It has a far greater level of detail than the other two !!!
    The previous owner had only assembled the forward Bofors and the torpedo racks so there Is plenty left to do, Including rebuilding the previous mentioned parts as there assembly was abysmal.
    Having waited so long to get one of these kits I am very disappointed at the poor quality of the mouldings especially the deck which has a moulding line down the middle from stem to stern, which seems to step from port to starboard, (don't quit know what to do about that)
    The cabin / bridge superstructure has positioning lugs moulded to the under edge which are supposed to align with Indentations In the deck but guess what, they don't align ! so I have cut them all off, the raised lip around the deck opening lines It up ok, so not so much of a problem, just annoying and reflects the poor quality of the kit.
    This will be the first plastic kit I have built for over 40 years so Its going to be a challenge.
    I'm a bit fussy so Its got to be right, think I'm going to have to find someone to assemble those brass torpedo racks though, don't think I'm quite up to that, any volunteer's ?
    I Intend to have the forward hatch open and will make a ladder down a access tube Into the forward hull. Have also fitted a minI servo to give the forward Bofors a degree of rotation.
    Will post some pictures sometime.
    Any advice / assistance from anyone who has built one of these would be gratefully received.
    Bye for now,
    John

    HI thething84
    Thank you so much for your response ๐Ÿ˜Š .
    Yes I realised about 30 seconds after I had placed the post that Googling was probably the way to go, which was why I never bothered to update it.
    Plans changed and I no longer need to use poly s for the foreseeable future but will check out Google if required again.
    Strange that yours was the one and only reply to date ๐Ÿ˜ญ I was expecting the responses to come flooding in considering how helpful other members of this site have been to me and others in the past.
    Perhaps people thought such a subject was not worth responding too.
    Anyway thanks again

    So sorry, I didn't realise (lack of concentration) that I was communicating with the same person in two different conversations.
    That will teach me to look at who I am talking too.

    Polishing your nuts round in a drill, now that does sound painful !!!! Ouch

    All joking aside small engineering projects are just not my forte. I'm more your blacksmith type if you get my meaning.

    If I do purchase the moulded Perkasa (whichever one)
    I can see it now, Glue everywhere !!!!!.
    Well maybe not that bad, but you know what I mean.

    HI Dave and thanks for your contact.

    I have visited your website on many occasions and very good it is too, unfortunately the specific information I require is not addressed there.

    I have purchased 3 Precident Perkasa's on eBay, the first 2 were terrible and quickly resold via the same source and at a profit I'm glad to say, despite my description being more honest than they were when I bought them.

    The 3rd one has been completely refitted with my preference of running gear, but the superstructure is another matter, there is only so much one can do with wood ! and I'm no chippie, which is why I am considering a moulded construction, its all in the detail.

    Just love the lines of the Perkasa, some things just look right, other examples being the Meriden Triumph Bonnyvilles & E Type Jaguar, you just know they will top the ton just by looking at them ๐Ÿ˜€ (If I tried to explain you wouldn't understand). ๐Ÿ‘

    I cant understand why you were the only one to respond, surely there must be someone out there with experience of one of these kits.

    Regards John

    Hello All.

    I am afraid I am In need of some advice again !

    I am considering purchasing a new Perkasa kit, I have two In mind, the Nautical Marine Models twin motor version at ยฃ235 or the Hooben three motor version at ยฃ200.

    Does anyone have any experience of either of these kits and could offer any advice to help me decide which one to go for.
    The number of motors has no bearing on my decision as I already sail the Precedent 1/32 wooden hull
    Perkasa running with just one motor and she runs fine on It.

    I am more Interested In opinions of the quality of the mouldings and the ease of construction.

    Looking forward to any responses, the more the merrier.
    Thanks for taking the time to read and respond.

    HI Dave
    Its the shorter of the Perkasa's at 36 inches, the battery is quite heavy being a lead acid and sits 6 inches from the stern and 24 inches from the bow so I think its well back.
    The prop is a red plastic one with a diameter of 2 inches no idea of the pitch.
    I don't have a selection of props to play with,
    Advice/suggestions on motor and prop size/pitch would be appreciated.

    HI Dave and thanks for your response.
    I am perfectly happy with the way the Perkasa gets up on the plane on full throttle. I guess I have the balance correct to achieve this.
    I am using 2 x UJ couplings even though the line of drive is quite straight. Of course if I were to fit a larger motor the drive would then end up slightly out, due to the motor output shaft being higher but no real way to remedy that without stripping out the propshaft.
    My prop is a 3 blade plastic one no idea of the pitch. What size would you suggest for a 550 motor ?
    You are of course correct in what you say about restricting the movement of the stick, but doing so with my setup would then prevent the boat getting up on the plane.
    I guess I will have to limit the time I run at full stick and cool the motor and ESC

    HI Nasraf
    I don't doubt what you are saying and after all you have been in the hobby for a long time and I respect your experience.
    But this is another thing I am failing to comprehend, I did take the time to check out the specifications and most of them are MabuchI 500/550's and the specs seem the same as for those supposedly sold as being specifically for model boats. Unless I made a error as usual, HaHa.
    Even some I have carrying a Johnson sticker which I have often seen criticised are actually Mabuchi.
    Anyway at the moment I have 25 of various voltages sitting on the shelf so replacements are no problem for a while.
    The 550/12v set up gets the boat well up on the plane at full speed so I am OK with this, I guess I will just have to try and keep the motor/ESC cool.
    But we have gone slightly on a side track as the original question was how to lower the voltage to the ESC by 3 volts, which in doing so should also underpower the motor just as we have been discussing.
