My only experience of a vacuum formed hull was a slightly smaller Tyne class lifeboat. Was satisfied with it, but glass fibre seems more robust, stiffer and stronger. Imagine a Vac formed hull will need full size stiffening bulkheads, which can be avoided with the GF version. Weight is very much a concern on this model and whilst Vac formed is probably lighter, this advantage may be offset by the additional structure.
Waveney class lifeboat was designed in the USA, but after minor adjustments the vessel was used by the RNLI in British coastal waters. I managed to pickup 1/40th scale Billings Waveney Class Lifeboat Kit from Ebay for £25 including postage that had not been started. This kit is designed for static display, but with some modelling skill it can be converted to R/C operation. This is now my challenge to convert this kit to R/C control and put as much detail on to as possible without spending fast amounts of money.
Last couple of days has seen some detailing added to the rear cabin using the Waveney Lifeboats book for reference. all bits n bobs have been scratch built and are the general bits that seem to have been added to most of the 22 Waveneys that were in service with the RNLI. The cabin was was then primed before adding rivet detail using a cocktail stick and PVa glue blobs. The whole thing has had 3 coats of VW Halfords orange spray. Shall leave that to harden overnight before I detail paint the roof grab rail, add the black anti-dazzle panel and the name panels made from official RNLI vinyl lettering. The whole thing will get a couple of coats of laquer and then will be considered finished!
I have a problem with choosing the motors for this boat. The lifeboat I built in the early eighties and upto today it had 2 x Deceperms fitted(6volt). One of these now as developed a fault and it is far too expensive to buy a new one,soI have decided to go down the route of fitting a couple of MFA850's only to discover that these love the amps and thus could burn my P94 ESC. I would like to stay on the brushed side as I have the techobots sound generatormand this connects to the P94. So which motors should I choose?
