Veron Chilton DW1

Ok new project.

I have downloaded the OuterZone plan with print wood scan and sized it for the original 18" span.

Power will be a Telco CO2 which I had lying around in need of an airframe and it will be finished as G-AESZ which is currently housed at the Shuttleworth Collection.

I thought it would make a fairly quick build as it's a simple design and straightforward to finish in Esaki Tissue. I have some silver and red in my covering box so the only thing I need to bother SAMS with is the 3/4" wheels.

I read on Mike Smith's FFscale site a review of a 16" version by Clive Gamble. He said that his model flew in rather wide circuits and that the wheel spat may have fin effect so I plan to deviate from the plan and hinge the fin and elevators so I can get it turn a bit tighter and maybe even ...fly indoors...

What a lovely looking aircraft.
i bet you will build a fantasia looking model and it will fly like a dream.

Chilton, dude.

Looking forward to some details of weight and where you need to set the 'throttle' if you can please, when you get there. I recently sold some of the Veron miniscale models including the very similar Dart which were for CO2 but they were slabsided fuse and looked pretty heavy so I moved them on, as they say. This plan looks more sensibly designed for lightness over ease of construction.
Good luck!

Looks good Chris, I'll look forward to seeing this one progress as well.

I'd also appreciate some words on your Telco. Personally, I never got on with them as I couldn't stop them leaking, nor could I get them to produce any useful power. I eventually went over to the Brown models and subsequently, the Gasparins. The latter two work very well. There's also the issue of where to get the gas. I've acquired a KP adaptor for the new Sodastream bottles, but the pressure appears to be lower than than originals. I get around that by putting in a larger motor and larger gas bottle. You can do the latter with the Telco, but not the former... Your thoughts, please?

The Telco appears to be a good one. I bought it new and it powered my only previous attempt at indoor flying in 1982! I have another but this one is the best running. They can be a bit hissy so you can't leave them long between filling and running the engine

A full liquid charge will give an engine run of around 30s with power starting to tail off around 18 - 20s. The punch mark on the throttle plate is at 11 o'clock. I was hoping at this setting it will produce enough power for a lightweight model. It flew my old KK SE5A so a light build Chiltern should suit it a bit better

The only other option I have in my CO2 arsenal are a couple of GM300's which are much bigger and would need a bigger model, maybe 20"+. I did do a plan at 20" when I was printing the plan out but that looks a bit tight for the 300. I could perhaps build it as the Mikron engined version with the engine up the other way but then its a change from the kit plan.

I'm still thinking the Telco is best option for a small light and quick build

I too use the Derek Knight adapter on the new Sodastream bottles which seems to work fine. I can't say I noticed a difference when I changed from the old threaded Sodastream bottles. I still have a couple of these older threaded bottles and an adapter I was going to pop round to my local airgun shop to see if they could refill them.

That all sounds good Chris. As you say, the GM300 does look a bit tight.

Regarding the Telcos, if you have a good one, which sounds to be the case, then you should be fine. I had about 10 in my time and ended up selling-on all but two of them.

Liquid charges - here's a few words of caution. When flying indoors, particularly at National events with lots of people in attendance and hence, high humidity, the liquid charge tends to promote icing up of the motor. It's particularly prevalent in inverted installations. Also, we've found that any swarf in the reservoir bottle can be transferred to the model tank when filling. So for competition flying, we tend to use a larger motors set to lower power, a large tank and gas charge only. There's no issue with using gas charges outdoors.

Thanks Andy. Great advice as ever. I was thinking maybe Kit Scale... might be more fun than just spectating even if it just does a taxying display !! like my last effort

I do remember buying a larger tank for the Telco. I'll go a check my CO2 box of bits.

Kit Scale, eh! Now you're talking!

There's a practice meeting at Bushfields in Peterborough on the 9th April, the Nats are in Walsall on 23rd April.

The Chilton is such a handsome little aeroplane, which I really like. so much so I'm building one of these as my Kit Scale Entry, I also have my own version that has been on the drawing board deep freeze for a while and I also built the Clive gamble version a few years back which was a nice little model.

Here is the the Clive Gamble one flying. This one is long since matchwood...

Thanks for the video Andrew. If I can get it to fly that well I will be very happy.

Yes very attractive little aircraft and hopefully simple to build. Are you building yours from the Veron plan too ?

I've not entered a scale comp in a very long time so I consider myself a competing spectator

I did manage to find a larger tank for the telco, I have a dim recollection of it being 6cc but could be wrong.

I've fitted this to the engine and with the same throttle setting and a gas charge I get a total run of around 25s and a gentler power run down from about 15s so hopefully enough for a 10's qualifying flight ( If it leaves the ground). Liquid charge gives a much longer run but getting it to run without icing up is difficult

Hi, yes it is the Veron one. This is how far I am with the build.

I have moved the rear peg forward a fair bit which is now allowed in the kit scale rules.

Looking good Andrew, you're way ahead of me.

I haven't built something so small for a while and am amazed at how clumsy I feel with it

I have managed to get a basic fuselage together this afternoon though

Kit scale I think is for rubber power only? Can you confirm please Andy? I can't see why - CO2 is equally challenging as rubber and many kits originally catered for it. Can you work your magic and let us in Andy?

Yowza, there's a big step between Telco 63mm3 and a Gmot 300mm3.
If its any help, my 75g 24" West wings Pussmoth is overpowered (for indoors) using a Gmot 120 at part throttle. That's with a 'rubber' plastic 6" prop to try to reduce the torque roll from the original prop.
I'm told there can be a big difference between early and late model Telcos but I can't validate that and I can't remember which was better

Yes quite a jump from a Telco to GM300, they are a powerful little engine. My avatar is a 1937 design by Leon Shulman called The Skyscraper built to 30" span which is pulled around very well by another GM300. I nearly lost it couple of times when its found some lift, it has a DT fitted now. Throttled back though I think it would be happy in 24" scale model ?

On the Kit scale front the rules say

This competition is open to any scale model built from a commercial kit that meets the
following general characteristics:
Maximum weight............................................................................ 200g (including motor)
Maximum wing loading ......................................................................................... 15g/dm2
Motive Power..................................................................................rubber, CO2 or electric
