Yes, you do.

FYI we flew the #1 production plane today. It flew great inspite of the fact that I almost killed it.

David McCutchen, my test pilot (shown in the photo) found out how it flies on one elevator when the other one came unplugged from the receiever.

FYI this one has a DA-50 in it. With 2 2100mah 6v Nimh battery packs mounted just behind the firewall it's still just a little tail heavy but flyable.

I believe the Evo 58 is the perfect engine for this plane. Proper weight, right size, gobs of power. The DA had plenty of power but since it needs more weight up front and the Evo is the same price, why not?
