>>The C90 should use less gas than the O-200, since its not running that fast. There are a lot of positives for that engine. Why is it so neglected?
Not readily available. Compared to C85's and O200's the production of C90's was miniscule. There is a C90 STC, but it currently resides with the estate of a former Skyport owner. We have been unable to pry it loose. John Cooper, A&P Skyport Services PO Box 249 4996 Delaware Tnpk Rensselaerville, NY 12147 518 797-3064 Fax 518 797-3865 www.skyportservices.net _____
