Profile Spitfire (oz13206)
About this Plan
Spitfire. Radio control profile scale model. Wingspan 760 mm, for .75 - 1 cc engines.
Direct submission to Outerzone.
Quote: "Hi Mary, This is my profile, sheet wing Spitfire. Powered by a Merlin (what else!). I built it back in 2014 and it has been a regular flyer ever since. It's my standard 'throw in the back just in case' windy weather flyer. It will fly when most other things won't. Very simple construction, but the radio box is rather small. I use a Lemon RX (highly recommended) and a 150mAh battery (good for at least 6 flights). The switch is a micro slide from an electronics supplier, just solder on your own leads. The fixed pick up tank feeds well through most aerobatics (even outside loops) but not for sustained inverted. Finish as on most of my models is coloured tissue, dope and clear. Regards, Warren"
Corrections?
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

ScaleType: This (oz13206) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
Notes:
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Supermarine_Spitfire
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Hi Warren, What’s the AUW including engine and fuel - I’d be keen to build this but using brushless etc?Many Thanks

Hi Andy, The all up weight is 344 g plus a tiny amount of fuel (about 4 g) so call it about 350 g. Light weight is critical so coloured tissue and clear finish is the way to go not heavy paint.
Good luck and make sure you post some pictures.

Thanks so much for the info - looking forward to putting this one together. I’ve recently made a P1174 (Outerzone) ‘RC prototype’… originally a single channel free flight plan but I added semi-scale engine intakes (added much strength to the wing construction for the rc version) plus canards-elevon mix and rudders setup for 3S/340W electrics. Just need a windy day and long grass to glide test it!!
All the best,

Hi Warren, Are the wings flat or did you round them at your chord line for some lift. Thanks TUC.
TUC - 11/03/2024
Looking at the plan, and reading the notes on it, the wings are shaped, not flat.
SteveWMD - 11/03/2024
The wings are shaped to an approximate lifting airfoil (flat bottom) but they are only 1/4" thick so the airfoil is far from critical, they are effectively "flat plate". Despite this it has quite a good glide when the engine quits.
Maximum thickness is at approx 30% with a more rounded taper to about 4 mm diameter at the front and a straighter taper at the back to about 1.5 mm thick. Weight and wing loading is more important than airfoil section. Mine is tissue/clear finish to keep weight down, Avoid heavy paint.

Hi Warren, thanks for getting back to me so quickly. I just have a few more questions. I assume the fuselage is constructed in 4 sections glued together, could this be built using one piece of balsa? Also is the wing constructed in more than one piece. I'm also a little confused about the wing specs - Wing Front 75 x 6 mm, Rear 100 X 6 mm. Sand appr. sections. Fit torque rods and tubes then re-fit inner sections. I really appreciate your input and I'm getting ready to build this Spits. Thanks for your time. TUC.
TUC - 12/03/2024
Hi TUC, you can email me direct if you like (on plan) so as not to tie Steve up with too many comments.
The 4 sections are required so the 6mm or 1/4" carbon tube can reinforce the fuselage. It really needs this reinforcement otherwise a poor launch tumble can easily break the fuse in front or behind the wing (ask me how I know!).
Note that the front section is 1/4" ply not balsa, for engine mounting and the carbon tube ties this together too. Are you going to use a diesel? (you really should for maximum fun)

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
