RE: Need help for mods on 1.60 os

No matter what you do, the 1.60 will not be strong enough. These planes perform best with 40-50cc gassers. Mine flies well with a ZDZ40RVL. For unlimited performance a 50cc would be just the ticket. If you do decide to go gas, don't use some of the heavier types as the all-up weight will become to high.
Safe Flying!
