 Right.... OK..... where was I again?!

 Oh yes, radio modifications..... I ended up with this!



I decided that the TGY-i6s was too nice a radio to hack up and probably modify beyond to  'return to factory'.
The new radio transplant victim is a HobbyKing 2.4Ghz Mode 2 4Ch Tx & Rx V2 - Price: 23.26 .... cheap enough to wreck and not cry about it!

The TGY-iS6 receiver had to come out and replaced with the new from the new radio.... . but I did have a bit of trouble with a knife blade!

Not Really!   :}

It's something I used to do from years ago, open up the Rx and cover the guts with wax - the original conformal coating!
 ..... but all I could find in a draw was an old red tealight... with Glitter!
( remember when we were kids, Mum would ALWAYS have a box of white candle in case of a power cut.  (.... 60's kid! )

 Powered it all up, works like a charm!
  ( With hindsight, I should have tested the radio straight out of the box first... got lucky again this time! )   ;D

The hull is basically finished now, last job ( yeah right! ). 
I'm adding the rubbing strip / fender band / strengthener ring?!
It's a 1mm x 5.5mm styrene strip, superglued on, hull rubbed back to bear wood.

The deck plate was basically a 98% bespoke without any trial fits!   :o
Just a bit of sanding an edge here and there and it was golden!
Combing strips easy install.
Trail fitting the mini bulwarks....

Wheelhouse next, here masking off the deck opening;
1. so I don't glue wheelhouse to the deck,
2. a spacer so wheelhouse doesn't fit too tight.
   ( Spoiler alert:  It is too tight! )

I tried to be clever  ( rushed it a bit )  and glued / build the wheelhouse in place over the combings, 'school leaver' mistake!
It didn't fit properly at all, too short and I thought I had trashed the parts but to my surprise, the superglue snapped clean
with no damage to the plastic. ... a good thing too, I got it wrong three more times!
..... very poor instructions, poor diagrams and my tools are rubbish too!  %)

So as long as it takes and no matter how fiddly it is, tape the pieces together, in place before gluing.
 NB: Some butt joints go inside some go outside.... sigh...

After a long and angry fight with the wheelhouse, I sort of got it all together.
.... sorry no photos or video, it's hard to use a camera whilst you're raging!

 Bulwalks in place too... curved bits down the front are the bulwark cappings.

NB: Notice the nice etchings ( routed? ) lines on the wheelhouse, should be inside the wheelhouse....  to mount t the steering console.   >>:-(

Trialing  Deluxe Materials - Plastic Magic  glue.
Excellent! Not as fast as superglue but wicks beautifully!

Next, how bad can you be at spray painting?!

 ( ... rhetorical question!   <*<  )



                                                                                                        ( Don't tell Stavros about this, I'll never hear the end of it! )   ok2

Well a couple of hours of sanding, scraping and mutterings later,  the effected parts are all cleaned up  ... well as much as I need anyway.

I think I know what went wrong this time round,  I'm using Halfords Plastic primer, it much thicker than I expected, dries slower, resprayed too quickly  .......   and I think i got sweat on to some bits.   {:-{


  So, are  isopropanol, Turps, Meths or Lighter fuel.... all OK as panel wipe on plastics?

I know it is pricey but Tamiya primer spray is very fine and dries very fast. I rarely use anything else on plastic or metal.


Good recovery  :-))

I spent all week trying to get some Alclad or Badger Stynylrez .... NOT cheap here in the UK!

I have some Vallejo Model Color Polyurethane Primer but it sands like PVA!  >:-o



Anyway, decanted some aerosol primer and tried my new airbrush..... this is a curious effect!?!

What's going on here?????  {:-{

Martin....do you know the type of synthetic [plastic is a big group of many variants] parts supplied in the kit?........the first spraying attempt appears as th epaint too thick or too many coats too early  :o , the last attempt suggests static electricity dust attracted to the parts  {:-{  or did you use double sided tape to hold the parts?......if so a possibility is the solvent fume in the paint has reacted with the tape & released a gas particles that have attached to the parts?


Get the bamboo kitchen Chopping board.......drill 50 x 1/16" diameter holes in random positions & blow out the dust ...spray board with IPA & let dry....try supporting the items on a bent Bobby pins.........

These days, Methylated Spirit is grain based and ever after evaporation and condensation still contains a trace of synthetic oil  >>:-( ...so after a gentle washing in warm soapy water [kitchen dish washing detergent], then blow dry followed by an aerosol pump spray of 99.8% IPA.......then a warm burst from the family hair dryer...the parts elevated on the pins in the boards will assist with drying.....

Finally try the spraying in the bathroom....[tiles & low dust environment].....[maybe wait until Mrs Davis is at the shops  O0

( remember when we were kids, Mum would ALWAYS have a box of white candle in case of a power cut.  (.... 60's kid! )


I still keep a wicker basket on top of one of my kitchen wall cupboards. It's contents are a box of candles, 2 boxes of matches, a ciggy lighter, & a couple of those plastic glo-sticks.


Alongside the basket are 3 enamel 'Wee Willie Winkie' candlesticks, which were the only lighting upstairs at my grannies until she died in 74. Those too all have candles in them & a box of matches in the bottom.


I was a 'Boy Scout',  'Be Prepared'.
