That stinger came off the back of Bill warder's Stealth, and was permanently fixed int there too, I don't see any problem in doing it really. I've got a good had inch of unsupported flex inside the stinger itself anyway.

Rich I should probably explain the lettering. I think this should suffice...

Looking good Andy. For what it's worth. Although I don't like not having vertical adjustment, I probably wouldn't have tried to make it adjustable either. Apart from the problem of the slots themselves, you'd have the problem of making the stuffing tube track. If the stinger can slide up and down, the tube needs to follow it. Unless your stinger is much the same I.D as the tube O.D, it wouldn't really work. You'd need to somehow build the tube out to the I.D of the stinger - then decide how to hide the slotted holes. Run it as it is and see how it goes.  I've spent time pondering over adding height adjustment to stingers, but haven't done it with either of mine yet. Having said that, I've used struts much more, and don't think I'd buy another stinger. Hope to see it running before long.

I thought yours were all fixed anyway mate..

Anyway, Just been waxing it a bit this afternoon, and got the rest of the bits sorted in the radio box. The gap was repaired by masking the bottom of the box up and pouring epoxy in.

List of stuff left to do:
Throttle / rudder linkages
Water cooling outlets
Bolt radio box in
Fit floatation and fuel bags.

Oh, and the rigger will be running in two weeks time, got a proper coupling for it this morning :-))

Hi Andy,
That looks superb, with regard to your stinger, in this months Model Boat magazine by Stewart Rae (SCOOP) building
a D Class Navaho running a Sikk 27, like you he permanently fixes the stinger as I have done many times in my builds.
I have building sports and racing boats for over 40 years, now I build steam models a lot more sedate.

Regards Mick
Indeed I do with the centre line of the flexi 1cm from the bottom of the transom  :-))
Cheers

Hi andy
just a tip for you,the exhaust header flange tends to leak through the bolt holes,replace the metal washers with teflon and add some blue thread lock this stops the leaking to maintain optimal cooling
I had it mine and took 3-4 attempts to fix the problem and this was the best solution i found

Andy just wanted to give you the heads up before you run the K30
dont fire it up the wristpin spacers are made out of the wrong material and is not hard enough they are breaking up and bending cranks and ruining piston jugs
this is happening to alot and a few are not happy about it
Iv been told to use the zen spacers but you have to machine the piston to get the right clearance but also just heard you can use the RCMK Evo 1's aswell but im looking into it more now and let you know asap

Hi andy
been on the RCMK website the K30's and the EVO's use the same spacers by the looks of it so dont use them either
looks like the zen 1 are the next choice

The only different between the two is the jug and piston / rod anyway...

I know but was told this is the easy fix,didnt believe it myself hence why i looked into it more
Im speaking to some1 at mo who can hopefully machine the piston and supply the zen spacers as there thicker
Hopefully find out tomorrow if he can and how much to fix the problem 
will keep you posted

After not touching it for a couple of weeks, I've just started again. Today, I've sorted the throttle linkage and radio box lid. Aerial is a bit close to the pipe, but not close enough to melt when the lid is secured down, so no worries there.

Throttle link was the right pain in the backside, couldn't get the angles right on the carb so I've flipped it over. Made up a support for the tube, and glued the whole lot into the radio box with Mr Sticky Steve's finest.

I've also just bought myself a new little toy, and if anyone is interested I could do a review on here?

Andy :-)
