I fly a Ventus C with integral tanks (no Bags) any issues with antifreeze and carbon/fiberglass tanks? What would be the recommended amount? Sounds like an environmental hazard to dump, and I certainly dont want to land wet unless I have to.

I have had issues with the Ventus fully loaded with water where the flaps seem to stick a bit. Not sure if it was a freezing leak or what, but was a little scary. Frozen rudder must not have been too fun.
