I recently bought 2 mid sized elec planes, about 48 - 50 wing.
An extra 300 and a Katana.
first flight on sat,......issue, extra suffered minor main gear damage due to full stall at no power, CG seemed to far to rear, Katana however, seemed to be correct in aspect of CG, Has more then enough power with 15" prop, seemed to fly relitivly well, even as shaken and nervous as i had become.
My question is this......a plane with this config, are they naturally unstable and touchy?
What can i do to tame down and stabilize flight characteristics ?
Thanx
Bob

I have a few Extra's ;nitro ,gas, and elect. All of them tip stall at slower speeds however they all fly like they are on rails. Just have to be on your game when landing. I also have an Edge , Slick, and Sukhoi and they too will tip stall if flown too slow. They also will start to act very wild if the CG is moved to make it more tail heavy. It can be a hand full until you get used to it. Try reducing the elevator throws a bit on low rates for awhile until you get comfortable with it.

That's normal for a mid-size Extra 300. They are fun once you get used to their stall characteristics. You have 2 options that will help lower the stall speed: remove weight from the plane or add washout in the wings. You can raise the ailerons a couple degrees to try and create some washout but it probably won't make a big difference. The best thing to do is learn to fly it properly. Be careful when doing hard loops, hard cornering and keep the landing speed up. You will get used to it over time!

Also be aware of high speed stalls .As Wombat pointed put in quick loops or steep dives with aggressive pull-ups it can induce a high speed stall. If it happens too close to the ground it could be the end of it. Make sure you don't fly high rates with too much elevator throw unless you are doing 3-D hovers, etc.. I had it happen to me once but there was enough room to get out of it but it took what seemed to be forever to recover. Hope it never happens again !

to the OP...depends on the brand and the design.....
you can have an extra in the 48" range that flies absolutely great....
but then you can have a 48" extra from another brand that has not taken the time to come up with a quality design in a lightweight package it won't fly near as well.....
all RC models are not created equal..

True, anyone can make a good flying Extra 300 by adjusting the scale dimensions and substituting lower weight materials but in the end you don't really have an Extra 300. You have either a fun scale, a plane that is not durable, or one that is extremely expensive (or a combination of all 3). Most manufacturers are forced to substitute easy flying for scale appearance, durability and affordability because that is their market. Most of the stall issue with the Extra 300 has to do with the original design and how it scales to model form. As long as you know what to expect ahead of time, they are a blast to fly!
