I recently saw a picture of Popsie in the BMFA News and decided I wanted to build one double size. While googling I came across this copy of RCM&E July 1992 with a double size Popsie on the cover. Does anyone know if there is any info in the Magazine on this model and can antone provide copies of what is there. I already have a copy of the plan which I need to get blown up.
 
Thanks in advance.

Yes, I'd like to build a scaled up Popsie too.  I suppose that you could take the original plan to a printer and get it scaled up but this is not always satisfactory.
 
I built the original in the mid 60's with a 1cc motor (free flight).  It's very rugged and has a large capacity fuz.  Good for electric flight I would have thought.  I, too, still have the old plan.  I started to draw up new plans for a 2x but was not satisfied with my conversion so abandoned the project.

I am planning to get plan (borrowed from a friend) down to the local print shop as soon as I can to get it blown up. The lines will be a bit thick at 2X but it should be just about usable. I also need to get some 48'' long balsa for the wings as 36'' will not do for the spars. I never quite know what to do about scaling up wood sizes. I tend to go for doubling of the cross sectional area and round up a bit.

Very nice too Stephen.  I've almost finished the 84" Southerner (similar fuz construction) which is a cabin version of the Slicker.  Vic Smeed designed some very good looking models.

Vic Smeed designed some superb models in my opinion.
Your Mamselle looks a very nice model Stephen,i'm building one myself at the moment.

Thanks Julian.  Is that the 2x that you refer to?  Yes, Vic Smeed was one of the 'golden' period of model designers.

The comments on the Southerner could be taken to mean that Vic designed it - I'm sure that wasn't the intention, but for the record it was a Keil Kraft design. Can't remember offhand if it was Bill Dean who designed it, but I think so.

I have had some trouble getting the plan enlarged. I took it to the local print shop and they did what they thought was 2X and it ended up only 1.4X.
 
My next door neighbor works for a major international print company and he said he would do it for me. He went the other way and I now have a 4X plan with 155 inch wing span. Its almost big enough for me to sit in. I am sorely tempted to try and build it below the large model weight limit but I would have top clear out everything in my garage.
 
My neighbor is going to do me a 2X now so I should be under way soon.I just need to source some 48" balsa for the wing spars although I will also take a look at what B&Q can offer in the way of hardwood alternatives. (Yes I know balsa is a hardwood)

A couple of points.
 
Bruce is right, doubling the cross sectional area is the way to go. I have seen a twoce size Supar Sixty where EVERYTHING was doubled. 1/2" sq. spars!!!  Weighed a ton and  a bit.
 
SLEC can supply 48" long wood. Just specifiy the grades that you want and that is what you will get. They can also usually supply 6" wide stock. Great service, super quality wood, it is where I get all my wood. Cheaper than the shops too.

slecuk.com have a very good range of balsa, ply, spruce etc. including 48" lengths. It'll cost you postage but they have an excellent collection and the prices are very competitive (in spite of recent large price hikes because of the poor value of the ££.They give 10% discount for purchases of over £50 and 10% + free postage over £100.
 
Have a look at the website.

I visited Selc at Wings and Wheels and they said the were waiting for the 48" lengths to come in. They may well have got it now. Thanks for the info.

Is a spruce spar much stronger than a hard balsa spar. If I go for spruce can I use smaller cross section timber?
