Hi all,

in this time of stay in and think of what you'd like to build and fly, I'm seriously considering an Ercoupe. I've liked them since one used to fly over us when I was a kid and I identified it from my Observer's Book of Aircraft.

Now, they look great in natural metal (what doesn't), so I'm thinking it would need covering in chrome film, but what is opinion generally of radio signal corruption with shiny birds?

hello martin,this has been discussed before,i can only speak for the "chrome"profilm….if the rx aerial is inside the model,the covering will pinch the signal....it has a thin metal foil in it....so on my models I leave the end bit of the aerial outside the fuz…

Hi Ken,

thanks. I was thinking how it's not so easy, with very short aerials to keep both poking out. Would a second satelite Rx. be a good idea in this situation?

hello martin,i can only speak for my models using Hitec 2.4g.....but as I've mentioned the profilm instructions tell you that the covering has a layer of foil in it and that you need to be careful about your radio installation.....if you google the matter,you'll get some more info...

Do you have the aerials outside or in the canopy?

The aerials are completely inside the fuselage, not even in the canopy.

Sounds like you've been lucky according to everyone else.

Or it's not an issue. I haven't seen any conclusive studies with results and the link above is anecdotal at best.

The oracover instructions advise getting aerials outside and in a different (geometrical) plane.

I make sure my aerials are outside, even on foamies...

As, let's face it, is yours, Callsign, by definition.

Oracover offer what they call Chrome film which IS backed with real aluminium and they do warn of issues with radio reception on this covering.

They also offer Brushed Aluminium film which is not metallised and may be close enough to a chrome finish for most people.

Personally I find their Chrome film to be too shiny to be realistic at model scale and it also seems prone to hangar rash which makes the model look tatty. However, that is likely to be my fault and as they say YMMV....

I prefer glassing and painting anyway!

Some years ago I resurrected a CAP Gladiator which I covered in silver Solartex. I positioned the receiver and aerials as usual where it couldn't be blanked by the engine and well clear of any metal but I couldn't get a decent range test until I put one aerial in the canopy and the other out of the bottom, both clear of the covering. That was with supposedly safe silver tex, I think Callsign Tarnish has been doing well to get good rangetests and no issues.

Alan, glassing and painting will never look like polished ally! However the brushed aluminium sounds good. I have seen several Ercoupes in a dullish mill finish ally, rather than the unbelievably time consuming polished version. The Spartan Executive at Little Gransden is almost too bright to look at! I have covered 1/32nd scale slot cars in Sellotape Aluminium foil and they look fine, so natural metal in the MUCH larger model aircraft scales is fine if properly done.

Thanks to all for the warnings and the solutions.

Martin

Not certain I agree with that.

These are not my models, but very much an aspiration to aim for (credit for pics and models by Phil and the team at Fighteraces).

I don't think covering models such as this in Oracover would give quite the same effect.
