If its only for a short time, everything is fine, but if you wanna enjoy your plane for awhile i would still choose the 3s version.
This setup is powerfull enough for some nice scale flying if you ask me, just my opinion.
I fly mine HARD with a 4s 2200 40c pack on the eflite power 25 1250kv motor and a 9x9 prop. Never had any problems at those speeds and no reinforcements of any kind have been used
