When the Maestro II is changed, which only takes about an hour, the kite:
- has like no oversteering
- is slower
- is way more precise
- has a bigger windrange in both upper and lower
- handles bumpy winds better
- is more stable in backflip and fade
- is more easy to trick
- has more overall control
- does way more tricks
- makes more noise
...all this is, with the materials of the original kite, after the modifications !
If you want to use better materials, then use the upgrades step by step, it gets better & better...
