Isthis new design the same as your previous Extra? Or is this a new design all together?
Such as a new wing, stab?

The new Extra 300 is very similar to the Extra 330 when it comes to design. The 300 does have a couple of changes to the design including a lot more lightning holes. Most of the things that you will notice will be in the fuselage when it comes to construction.

The new Extra 300 is I am sure you know a midwing. It shares many of the same features as the 330. We have in addition made changes in the wing and tail. The ARf's will be set up for both cans and pipes, We are increasing the the limit on the engine size from the 140 -150cc to now include up to a 200.

The PAK kits will be here in about 5 weeks, we have a limited supply of those available. Our next shipment of the new 300 ARF will be ready early April.

HI Al
Your new extra 300 sure looks huge on your website. When will they be in the country?

I think Robin would kill me if I purchased one before Christmas.


Take Care

Bill,

who's going to tell!!!!!!

The 300 looks great.
I hate you guys, you keep coming out with new stuff I wan't.
Just when you think you have everything, this happens.
Good luck with the plane.

Hey thats what were here for.

Highlights on the flight differences between the Radiowave 300 and the 330. I noticed the biggest difference when putting rudder in during a point roll, either horizontal or vertical, planes often shift in the pitch during the roll. This makes coordinated rudder inputs during a point roll difficult. That's what I like the best about the 300. A close second is axial vertical rolls. During a vertical point roll (half, quarter, eighth,) with rudder corrections for wind, has a very axial presentation. When shifting rudder direction at the completion of each half roll for crosswind correction, the plane allows for this input while presenting the roll very well on-line.

Another item of interest is the snap exit. The 300 design has a much more predictable exit on the snap. I don't know if its the better visibility of the mid wing, or the dampening of the pitch and roll (due to it having a more neutral rudder to elevator feel, with little pitch coupling) but I found that its really easier to nail snap rolls.

How about coming out with a 33% version of this airplane that would be perfect for the new 75-80 cc engines. That would make it more affordable for a lot of people. I don't know if it's possible to design it so that you get away with one high torque servo for each aileron without having flutter problems, but that would even make it cheaper and lighter IMO.

I think if cost is a concern than you should look to stay in the 30% size market.

What you'll have to look at are the diamensions of the 30% class, I think you'll find there are a few that will handle the 75 class engine. Our 35% will fly fine on a good 80 cc but you will sacrifice some unlimited performance.

There is not alot of difference between most 33% and 35%. I think you'll find on average that a true 33% to 35% have a wingspan of 100 to 106 inches depending on which plane you look at.
