Extra330LX 3.0m V2
Instruction Manual
Even though this Extra330LX 3.0m seems to be very similar to its predecessor with just a longer
canopy and a little bigger control surfaces, by no means this is the case. It is a completely new
design, where almost nothing bases on something which had been done before. This Extra is a
real REVOLUTION in the Large Scale Aerobatic Market, something never done before,
something so special and so different that it was a real risk to start this project in the first place
- because many told us that what we were trying to do was impossible. Boy were they wrong!
The CARF-Models Extra330LX 3.0m is actually defying gravity and inertia.
