This time I will try to remember to put in the ‘source’ information on the bits and pieces I use........... In the most recent piece I should have included exciters/transducers are Dayton Audio DAEX 25VT -4, 4 Ohms – 20 Watt pair, obtained from Sound Imports Netherlands and very quickly as well. The sound unit is a Mtroniks Digisound 5M diesel sound, available all over the place. Now to look at where I am at. Exciters are in place as high up the Hull as possible, but remembering the Deck level. Used the adhesive pads as supplied after wiping that part of the Hull with Meths and Silicone adhesive to keep in place as well as using the wiring tidies from Modelsport Ltd., for the cabling. (Pic 1+2) Before I start the motor and controller wiring I changed the platform ‘up front’ (pic3) with a piece of thin ply which I have given a couple of coats of varnish to waterproof. Then I thought to myself “why am I waterproofing this when, if it gets that wet, it will have gone to the bottom and be useless anyway”! (Pics 4) However, the platform gives a little more choice in terms of layout of other components and my plan for them is not really settled yet. I am concerned about the stern and possible swamping, but it currently seems the best place for the upgraded battery. (Pic5 ) Whilst talking batteries, I have gone for a separate battery supply for the receiver and hope to use the Bec supply for running other less critical items. Also the fitting of the battery in the stern bay drew my attention to the rudder servo for a couple of reasons. First is I am still considering increasing the size of the rudders and I am assuming that will increase the strain on the servo. The servo supplied is a standard issue and not water resistant so I have gone for an upgrade as shown(Pic6) That gives torque increase of 17Kg/cm over the Hobby Engine S1040C and has metal gears, metal control arm and waterproof for 20grams extra weight. Second is the closeness to the new battery position. So I was going to alter the servo arm setup anyway and the new metal arm suits this well. Maybe my ‘tutors’ will consider all this to be a little ‘over the top’ but I do so enjoy messing......................... New Servo DS 3218 by AYANI from Amazon. (Pics 6/7 ) Following that distraction, back to the front end and the Motor/Mixer placing and wiring. Now a little time ago I drew a plan to see what could go where and it came out that most of the ‘bits’ would go in the front bay with motors to be wired once power was brought forward, followed by the Esc/Mixer. (Pic 8) At that time I bought a P94 dual esc/mixer from Action Electronics and got the 20 amp version to be on the safe side................. My ‘guardians’ did point out this was ‘over-kill’ but I had already got it. Now, when placing the unit on the mounting board I found that the heatsinks made it too high to fit in the Hull! So being a spoilt brat only child I ordered the 10 amp version and as usual it came very quickly from up here in Bangor. ( Will keep the other one for the next project............Happy Hunter??) Unboxed it and it looked just the same, heatsinks and all. (Pic 9/10 ) So at that moment there was a bit of a set-back so I rang Component Shop at Bangor, they said “take the heat sinks off and you have a P94 lite”! Such a simple answer and such a nice chap. (Pic 11 ) Now a quick 'measure up' before I have a glass of wine (Pic 12) and does it all fit...? Well it appears to at the moment! (Pic 13) Next time really going to screw down the components under the forward hatch and wire it up. NPJ
So, 1st day back on the Solent since the weekend. She is all but complete apart from a bath leak check and ballast if required. A couple more coats of varnish/stain on the stand and that’s about it. Following that will be the lake and hopefully some nice video!
Had a couple of hours of good light after work so cracked on a bit more. Finished the last Bulwark and all the splash boards (if thats what they are called?), sanded and sealed. Last job of the day was to spend some time masking the whole hull leaving just the deck available for a few coats of Halfords grey primer which will be the final deck colour. No more work until saturday now, but next thing is to continue masking leaving the Bulwarks available for spraying white. This to be followed by stanchions, rope work, anchor and some weathering before a final few coats of laquer (Less the deck that will be matt varnished. Still a few jobs beyond all this inc bath test and ballast as required and a few other bits n bobs, but she's getting there!
Started back on doing some work on the inside today. On/Off switch, ESC, 2 x Motors (MFA 800), Prop shafts and Prop shaft supports fitted. Another coat of 2 part resin and a coat of varnish inside to end the day. Tomorrow plan on getting the battery/sound card/speaker tray in and to give the outside of the hull its 3rd and final coat of resin before its ready to final sand and start the painting. Jusdt a couple of very small jobs left on the upper superstructure and will call that finished! Hope to have a video uploaded tomorrow showing working lights and radar (providing the searchlight arrives from eBay, if not wednesday.
Yup that's real GOLD, and I have used for fifty years on real boats as well as models. I rub down with 2500 wet and dry after the final coat has hardened for at least two weeks. Then use a beeswax polish on a slow orbital polisher or by hand. It's really worth the effort. Best of luck Colin.
Hi Alan, just a point that John made, if you have a paint shop in your area that does custom paint finishes, watch them, they consider 30 coats of lacquer only adequate, but the finish soooo deep but 3 weeks to finish a car, bit OTT Mark
As an afterthought when you have rubbed down with wet and dry used wet wash the paintwork off well allow to dry and then use a lint free cloth to make sure all the old paint dust is gone. Make sure you work over a surface you do not mind being marked since the drips from rubbing down make an excellent paint on an absorbent surface!! ( yes I made the mistake so I KNOW). Its a very messy process but well worth the effort.
