Some of you will notice i have posted quite a few things regarding a Plastic fantastic airfix vosper MTB.
Is this what the modelling world now generically refers to the plastic kit conversions?
Anyway, after much searching, i found the thread relating to the use of servo's to power control these types of kit, finally.
The upshot of the search and the testing of the drive train, suggests that the higher the speed you need to achieve the more you will need to use a generic ESC, the slower more plod along boats which can quite happily run with the servo motor rpm can use the servo.
So i just need to get this right as i have 8, yes 8, plastic fantastic boats to fit out, 2 vospers fully sealed against water ingress but to cruise at a scale speed of about 20 knots min. 1 german 'S' boat to refit (again) and another to build (possibly another to resurect from my childhood) a Revell pt109, the running gear in this may be easier to fathom out as it is deeper, a LCT and a battleship at 1/600, the other 3 boats not included in the plastic fantastic size range, are a refit of a matchbox flower class (yes i know it is still classed as a plastic fantastic, but at 3ft it's not exactly got a space problem, a cardboard shell to complete and seal etc, based upon a castle class corvette shape and a GRP tug about 9-12" long.
For the vosper MTB's i have a motor from maplins and in the test it works quite well, whether it does the scale speed of 20 Knots i am unsure, though when it gets put in the water (bath) i doubt it will preform anywhere near what i expected, i think i have got the amp setup right and was wondering if this picture confirms that this is ok, not really sure what the amps are but the meter shows 2 notches past the 50/10/2 marking on the dial when the selector is on 0.1/.05 - any idea on what amps it was drawing at full throttle (sounded like it was the fastest it would go, setup was no grease in prop tube (forgot) and free running in air, will be a pig to fit in the boat.
