OK, I would not recommend either of these planes for windy day flying. The ventura is pretty light and the Spectra is too under powered. Once you have it up there the Spectra would do fine.

Windy day thermal glider flying?

Or windy day slope flying? Very different!

Or windy day parkflyer flying?

What other experience do you have? What have you mastered so far. Tell me about your flying in the wind. THEN I can make recommendations.

RTF only? ARF? Kit? Do you have a radio?

Talk man! Tell!
