I have just started this build and was wondering what size engines people would recommend.

Hi - I have one of these models partly built and the engines are very small with the legend RF 020-th on the motors - I have yet to try it out as other models have taken precedence but hope that one day I shall find time to complete it  Stuart Hunkin Cornwall

Hi William - I have just looked up the original purchase details and they are as follows below - "This is a Billing Boats static plastic boat kit of the RNLI Waveney Class Lifeboat.However it was modified to run on RC as a small easily controlled model boat to run on a garden pond. An excellent runner it uses an Acoms AR201 two channel AM receiver driving twin motors via the fitted ACTion  speed controller. Original vac moulded deck has been fitted out and test run The remainder of the kit is still in the box awaiting fitting. I would suggest modifying the existing deck layout to allow access to the batteries etc. The hard work has been done and the boat powers along quite well. There is no hand controller with this boat, however they are very cheap and easily available from among others Howes of Oxford."   This was one of my impulsive purchases with the intention to complete it but has been overtaken by other larger RNLI lifeboats.   The original chap who built it came from the Peterborough area and it may be that you might find some information if you made contact with Howes of Oxford who might have supplied the motors  regards Stuart

Cheers for that I will certainly try Howes and see if they can help.
Regards William

I would start with two MFA 140/1 motors (Part No 457-RE140/1) running on four cells. This is the 3v-9v version. If you use an ACTion P68A ESC then you''ll probably get away with just the one ESC, with the motors wired in parallel. Power comes from the same batteries as the receiver. You can find out more on the Component Shop website and the tech specs of the motor are here http://mfacomodrills.com/motors/140.html
You WILL need a 0.1uF ceramic capacitor across the motor brush contacts - these motors are electrically very noisy without it.
