Annother Islandmodels 1/3 Scale Ka8b build log

Your K8 looks fantastic John!! 
And that is without mentioning Kate! 

Must be close to the first flight now?

Hi Fred,
Yes it's nearly there.
I got some primer on the tail feathers and fuss over the weekend and I still need to fill some weave in the glass cloth and recoat with primer. Have not yet attempted to paint the wings, I want to get a spray gun as using aerosol cans will cost a fortune. 2 x cans of primer used so far and have probably added about 40 grams to the model lost about 700grams of paint and propellant to atmosphere either through overspray or evaporation.
After painting only have to fit control horns and final linkage to servos and recheck cg otherwise she is ready to go. 

Can anyone recommend a spray gun or type of spray gun to buy, an airbrush would not have sufficient coverage to spray a large model Total surface area is about 6meters sq, and there is a huge choice in mini / touch up spray guns available. Question is which type would be most suitable and what size nozzle. Also what type of paint is reasonably priced and easy to use with spray gun?

Any advise would be appreciated

I'm hesitant to recommend anything as I find painting a royal PITA, but when I am not using rattle cans I use a touch up gun.

My one is a Draper gravity feed (i.e. cheap) and works well enough for my needs, although these days it's mostly used for fuel proofing after I rattle can the colours.
Having said that, I don't build scale models.

Looking good! I'll keep Kate warm if you need to send her away...   

I use a HVLP touch-up gun with a 1.0mm nozzle for among others my Ka3.

Thanks for that,
I have been looking at a couple of HVLP mini guns but was not sure as to there suitability for our needs however it would appear that one of these with a 1.0 or 0.8mm nozzle should be suitable. I just did not want to rush into buying a gun and then find that I could not get to operate it correctly either by using the wrong paint/ nozzle or through bad setup. I don't mind spending some time learning how to set it up or find the correct consistency for the paint once I have started with the right equipment.

Thanks
again

Hi Ralph,
I have not yet fitted the control horns and linkages to the ailerons it is one of the few jobs left to do, glue aileron hinges and fit control horns and linkage and put decals on the wings and she is ready for first flight. I plan on using 3mm  x 25mm horns and clevises from Hobby King. I will be using 2mm stainless steel pushrods.
The elevator is operated by 2 x HS85 mg servos here I have used Medium sized Kavan plastic horns and again 2mm stainless steel pushrods.
The rudder horn is home made from 2mm Glass sheeting.

Fred
Can you advise as to what the control throws should be?

Looking forward to hopefully maiden the K8 at the weekend

Ralph
The horns that I am using for the ailerons are similar to the ones that John has recommended, they are listed as 3mm x 50mm
Heavy duty horns.
