I picked up one of these challenge boats after talking to one of the Knightcote MBC members (possibly Geoff but I'm sorry as I am hopeless with names) who kindly showed me the insides of a couple of boats from the display stand. Some are driven by dismantled servos or what got me interested were some by small brushless motors. I decided to have a go because I tend to build too heavy; not done anything this small; and I haven't used brushless. Unfortunately, I didn't get details of the brushless motors and I can not find a supplier for any that small - I think they were outrunners about 1/2" diameter by 1/2" long. I would be grateful if someone can tell me what they are called and where to get them.
I have opened the packet and the hull is about 18cm long by 6.5cm beam. I estimate the displacement needs to be about 50 to 60g (2oz) at most.
Also in the packet is the entry form with the background information and rules. I have scanned it and included it below so those who didn't get one have a better idea of what this is all about.

Speedline ‘Build-a-Boat’ to beat Cancer Competition
We aim to raise funds for cancer research with this competition - by ’buying a ticket’ in the form of a very simple boat kit for you to build and MODIFY to be only limited by the size of the hull and your imagination and ingenuity.
The hull/design is based on a very popular “Diana” model introduced a couple of years ago. The kit provides a hull, deck, sheets of plasticard, prop shaft, rudder shaft and tubes, a brass fret prop and rudder.
The model only needs to proceed under its own power - rubber, steam, electric — you decide. it can be free-running, tethered or radio controlled.
There will be a series of meetings during next year when the boats can be shown and final judging will take place at the Model Boat Show at Warwick next November.
The costs of producing the kits (40 only) are covered by Speedline Models and ALL proceeds will be donated to Cancer Research.
(If you need any ideas as to what can be done, visit the Knightcote Model Boat Club stand and see the variations-on-a-theme on their Diana display - remember, it must be based on the Diana hull - no extensions below the waterline. Club members will
probably assist with technical details if you ask very nicely!
Entries will be judged on originality, ingenuity, technical innovation, performance on the water and aesthetic appeal.
Prizes will be awarded for first, second and third places - to be announced at the Model Boat Show, Warwick in November 2015.
