    Air Sea Rescue Launch 123
    Model is an early Vic Smeed semi scale Air Sea Rescue Launch. Built about 30 years ago but never finished. Now in the process of being finished. Still another gun turret to fit along with handrails, mast, searchlight, captains windscreen, rescue nets etcetera. Still having problems with my Mtroniks speed controller BEC giving faulty signal to the receiver at voltages near to 6.7 volts. I have now installed a separate receiver battery and it appears the faulty signals have disappeared.
    (Naval Ship) HMS Crofton
    The model was built over an eighteen month period from 1987 to 1988. The plans were obtained from the MOD, along with photographs and info from many sources. The model has been constructed from wood,plastic and many household bits and pieces. (Motor: Decaperm) (ESC: Bobs board) (8/10)
    (Pleasure Craft) Marina
    The boat is a Graupner kit from the late 1970s and has recently been updated with new Spektrum radio tx and Mtronik speed controller. and (Motor: 380) (ESC: Mtronik 15 amp) (8/10)
    (Other) Huntsman 31
    The boat is an original Modav kit built in the early 1970s fitted with anEnya 35bb111 and recently renovated and fitted with a brushless motor new prop shaft and electrics. Model is still to be completed windscreen and fittings still to complete. More photos I just need to add the anchor fittings and handrails. First launch planned for the 22Aug 2018. I have tried to keep as much of the original 1970s boat as possible. (Motor: 3548 1100kv) (ESC: Hobbyking car esc) (8/10)

    Built from a Vic Smeed plan in 1986, fibreglass hull, wood and plasticard and plasticard superstructure and various plastic, wood and metal fittings. (Motor: Graupner jumbo 540) (ESC: Mtronik) (5/10)

    Doug, yes I intend to reduce the rudder throw as it is to severe. However when I ran the boat in the video I had the rudder control on the Tx back to front which rather complicated matters. This is now reset. The speed controller is an Mtroniks viper marine 15 amp unit suitable for up to 12 volts. Unfortunately the motor is the original 6 volt jumbo 540 from the 1970s. I am running it on a 7.2 volt Nimh pack. I contacted Mtroniks and they said if the voltage to the ESC drops below 6 volts then the BEC will not work. I think under full load the voltage may drop to 6 volts but when I have checked the battery voltage after the problem occurs it is at 6.7 volts. Anyway putting the receiver pack in has solved the problem because when the main Drive battery has run down now the boat speed slows but control is maintained.

    Model is nearing completion troubles with BEC voltage fluctuations have been solved with a separate receiver pack. Still some fittings to add to finish in accordance with Vic Smeed original design.

    ๐Ÿ“ Chine Spray Rails

    I have a modav Huntsman 31, which heels over quite a lot on turns even after slowing down. I was looking at the chine spray rails at the rear of the boat (see picture) they do not dip below the outgoing angle of the hull as shown on the plan (see picture). Would a triangular fillet located under the existing chine strip to simulate the plan for a length along the hull from the transom improve the heeling over in turns?

    Doug, Thanks for the reply, as far as I was aware the S type plastic props were less pitch than the X type plastic props. if your 35 mm metal prop is 1.4 pitch then it is similar to the X35 plastic prop I used in the first video. I think I need to investigate diameters and pitch a little more. Last week running my Huntsman I had an X40 plastic prop on and it was too large and way too fast, a friend running a 34 inch fire launch runs an X 35 so I may go back to look at a ๐Ÿ˜Ž35 mm dia metal prop and look at the pitch.

    Help required, I have just started to look again at this boat which I partly built the hull and upper works for many years ago from a model boats extra publication. Has anyone built this model as I have a number of questions re finishing the balsa hull, modern control and running gear for this model. It currently has a Graupner Jumbo 540 motor installed but nothing done to the balsa hull or upper works or control

    Built originally in 1973 from a modav kit and powered by an Enya 35bbiii. Now running a 3548 brushless motor and 5800 3 cell lipo. Model in video was running an x35 prop with +/- 20 degrees of rudder, very sensitive on turns. Today's run was on x40 prop considerably faster with reduced rudder throw of +/- 15 degrees. Current draw was 30 amps max watts 376. Still too sensitive on turns.

    10 months ago by Will-I-Am ( Master Seaman)

    Doug,
    The 6volt battery is currently an NiMh battery not an SLA. The problem was that according to Mtroniks the minimum voltage to the ESC to adequately run the BEC connection is 6volts. That is why I was getting erratic control when the battery voltage was 5.6 volts. The action speed controller will work 2-12 volts and I am going to use a separate receiver battery as suggested by Dave Milbourn just to make sure.
    Regards Will

    Help required please, I have two Graupner Jumbo 540 6volt motors in an eboat circa 1978, I had fitted an Mtroniks speed controller replacing the Bob's board only to find that when the voltage dropped below 6 volts down to 5.6 volts I was experiencing intermittent operation of the esc. I have been informed by Mtroniks that the minimum voltage for operation of the esc is 6volts. Graupner have also confirmed that the maximum voltage for the Jumbo 540 motors is 6 volts.
    Do I have any alternatives other than refitting the Bob's board?
