38" span Spitfire - Balsa or Ply

I am planning on building a fuel powered Spitfire with a wingspan of 38". The plan that I have identifies the material to use is balsa. Looking at the size of this model my thoughts are that it might be better to use ply. I have built many rubber band powered balsa models and this will be my first rc build. Should I stick to the balsa or use ply? I would welcome your thoughts, many thanks in advance.

Sean, may I respectfully advise you to start with a much less complex model for your first RC attempt? Let alone easier to fly?

"Scale Models" and "First Time RC'ers" do not mix well.

As to the balsa vs. ply question, a model as small as a 38" Spitfire will need to be as light as you can get it to fly well... fuel or electric. If the plans call for balsa, use balsa.

Many thanks for your reply. I welcome your advice and have thought a lot about this. My previous post was maybe a little misleading. I have a Hobbyzone Supercub which I am using to learn to fly. I understand that you need to learn to crawl, before you walk and indeed run! I intend to do this. I also have another project which I found on the internet. A fully flying model made from insulating board. This guy posted a video showing how to build and also showed it flying. I intend to follow his guidance also. The Supercub is ok but for me its the build. At present I am building a Keil Kraft Radian .049 control line stunt model. just need to source a Wen Mac. The Spitfire is a long term project. I fully intend to be a competent flyer first before flying any complex build. I will also joint my local RC club.

To that end, thanks for the advice and I reckon I will use balsa for the Spitfire Many thanks.

A wingspan of 38" counts as small for an IC powered model and it will definitely want to be balsa. What engine are you planning on using ?

BTW I'd use a diesel on the KK Radian. Wen Macs were never very reliable, even when not antiques. The Radian is a pretty little stunter, but not the easiest thing to fly if memory serves .

Steve,
Thanks for that. Not sure what engine I'm going to use. Still researching that. I want to get ready for the build so I'm checking over what I need to know and understand for that.
Thanks for the advice on the Radian. I was looking at a couple of Wen Macs on ebay. After reading your comment I might rethink that. Any advice on types/makes of diesels that would do?
Many thanks for your time.
Sean
