Extra 300 (oz3606)
About this Plan
Extra 300 EP - Radio control scale aerobatic model.
Quote: "Hi Steve, Please find attached plan of a radio control, electric Extra300. I drew the plan up with reference from an ARF kit... which came with no plan (and I figured well, what happens if I crash... so I drew it up while it is in one piece). The plan is entirely my own work and I am making it available to you free to post on your website where it will also be freely available so I see no issue. I just wanted to send you something so that I can contribute towards your fantastic web site."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsHi Hardie, its a great plan however i dont find any marking of wing and stabalizer slots on fuselage. hope you rectify this.

I'm sure this plan is complete. The horzontal stab slots into the gap shown (measure the size, it is an exact fit) and the wings are retained with aluminium tubing which slots into the holes (2mm ply reinforced) in the fuselage sides. Looks fine to me.

I built this plane and she flies very well. True the plans are not thorough but if you enjoy designing solutions this will work for you. CG is similar to other Extra 300s.

Hi! Beautiful plan, but i need to know what thickness are the hull ribs (F). Side view shows 3mm and top view shows 2mm.

* 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.
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.
