Have heard that the Extra 300 won't 3D

Considering that Christophe Pasant, Jason Shulman, Quique Somenzini, Sean McMurtry, Mike McConville all flew Extra 300s at the last TOC, the Extra 300 will 3D

Let's see?
TOC 2000: First place Cristof with an Extra he designed
Second Chip with an Ultimate bipe
Third Jason with a Fiberclassics Extra

Masters Qualifier 2001 First place with a RadioCraft 35% (beat all the larger planes in the qualifier) Pilot Rob Sarlan NE IMAC director

Yuri Higuchi with a self designed Extra does a breathtaking demo at every field I see him fly.

I could go on but what would be the point? You must be right! <vbg>

EXCAP232 (the EX is for EXtra) love em both.

To clarify, someone told chevy13 that the Great planes 40 size Extra is not a 3D plane. To some extent i think that is true because the proportions of the control surfaces are relatively low.

For the GP40 EX: aielerons are 1 inch with a mean cord around 10.5 inch roughly 10% elevator - stab --- 30% rudder - vertical roughly 30%

For 1/4 scale H9 edge. you have 3 inch aielerons on a mean cord wing of 12 inches or 25% elevator proportions are near 50% and rudder around 70%

Many 3D ers are using control surface proportions even higer than these.

Anyway, i haven't been flying it a lot, but i have TR'ed my GP40 extra and had a ton of fun with it in spite of its smaller control surfaces. I use the Saito 100, MA 14X6. It weighs in at 6.7 pounds.

I think you're right, I saw Chevy13 is building the 40 size extra and wasn't aware of that when posted above.

My stepson just built the GP .40 Extra 300 and he bashed the elevators and rudder. The rudder was modified after a Cap and looks as if you had robbed it from a Cap. On the elevators he enlarged them by 1/2", probably should have went a full inch and built in counter balance as that of the larger birds.
Flight performance has greatly improved in the advanced aerobatics. With the CG set on the forward recommended range it will still almost go completely flat during a inverted flat spin, just a slightly AFT CG and she should be there. She wont waterfall due to not enough elevator I dont think. Has GREAT rudder control and I believe she will have enough to knife edge loop. He is using a OS 70 but with a OS 91 being only an oz 1/2 or so more it would be a better choice, or the Saito 100 I beleive is lighter than the OS 90 just slightly.
So if you rework some of the control surfaces she is capable of 3D IMHO.
