Scaling Kits Larger?
How do you scale up a kit?
Do you use a percentage? 10% more wing cord and 10% more span? And 10% longer fuselage? 10% larger tail surfaces?
I had some basic design ratios once, but have lost the file. Somebody had pics posted of span/cord ratios and span/length ratios. Ratios for square inches of tail surface too wing area.
I have a kit that I want to do this with. I want to keep the fuse width the same so my cowl still fits, but I want to stretch the overall length of the fuse and wings to accommodate a larger engine (gas). Not sure if I should make the fuselage taller too?

Scaling does not mean just the parts you want but the whole thing!
In your case just ten percent wider on the fuse won't be enough to be concerned as you seem to be.In other words just scale the whole thing and don't worry about the rest.
Now to answer your question, the best way I know of is to use TilePrint (do a search) to do the job. It is easy to use and is under 16 bucks to purchase. Yopu can not beat the price for what this program is able to do!!!

I don't know what kind of plane you are considering or the difference in engine sizes. A high performance plane may have additional considerations like flutter, spar flex, etc.
What are the specifics of the project?

RE: Scaling Kits Larger?
Take your plans to the copy shop and enlarge them to what size you want. Engine, etc., will depend on what you end with and expected weight. You have to increase hardware, servos, etc. You have to enlarge the complete kit, not just parts. Happy building!

RE: Scaling Kits Larger?
Whoa nelly! It sounds like you really don't need to scale up your entire aircraft just make it longer. if you scale it up your cowl wont fit.
Basically I would need more information as to what you have, then, what you want. what kind of plane? is it a kit? what kit?
the more information you give the better answers you will get. Basically it sounds as if all you need do is add wing tips and move your empennage rearward. or again maybe not. we really need to know what ya got and where you wanna go with it
