Thanks so much you two. I discovered Viking yesterday while looking on line. It's a one week rental. I aim to check with my local EAA chapter as well. The Gyrocopter guy asked me the same thing and no, I hadn't considered it. Great advice Darrel. Thanks for the offer, I may just hit you up on that Balance Master. I noticed one mounted on one of their gyrocopters but I believe the concensus on the forum some time ago was that the Dynavibe is capable of getting the ips down below that of the Balance Master. The BM website shows it bringing ips down from .36 to .10. I recall achieving .04 with my original install using the Dynavibe and some were getting down to .02 if I recall correctly. I am shooting for those kind of numbers.
