The RCGroups 330SC - RC Groups

The RCGroups 330SC

Jim Bourke just took delivery of his new full scale 330SC competition plane. This single seat 330 is nimble and fast! Read on for more info.


The RCGroups/FlyingGiants Full Scale 330SC!

Jim Bourke has been sending us photos of his 330SC as it neared completion. When I found out he was flying over TN I made the request that he land at a local airport so all of you could have a closer look. Jason Cole and I headed out to the airport for photos and some video.

About the Plane

The SC is a single-seat version of the notable Extra 330 aerobatic plane. The 330SC is lighter with better performance all around. This year as a member of the US Unlimited Aerobatic Team, Jim Bourke will be flying at the World Aerobatic Championships in one of these amazing planes. All but one of the team members will be flying the 330SC. The 330SC is the sum result of 30 years of aerobatic experience.

From Jim Bourke:

"There is no comparison between the 330SC and my Yak. The Yak 54 is a capable airplane but is very draggy compared to the 330SC. Just for a quick comparison, I flight planned for 135 kts in the Yak. I flight plan for 175 kts in the Extra. That's on 45 fewer horsepower. The Yak is fun because of the huge prop and insane power but it is not nearly as nimble. Truthfully, the yak scared me a few times because there isn't a lot of margin for error. I feel 100 times safer flying the extra at low level."

Azboloutely beautiful! Can someone explain the science behind the (for lack of a more knowledgeable term) "squared off" prop blades?

Round tips are more efficient (less drag), but a propeller must be short enough to keep the tips from going supersonic. Therefore high powered engines will have squared off props which can deliver more power, even though it is less efficient. The same thing holds true for multi-blade props. More blades are less efficient, but it is the only way to get more power at the prop without the tips going supersonic or the blades hittting the ground, both of which cause some major problems ;-)

The EA CS330 is freaking awesome. I bet it cost more than many RCG user's homes did. Tell me, did Jim get the money from running RCG or did he marry well?
