Greg posted a video of the Rotax gearbox with an adapter on the Facebook Yamaha aircraft page and someone asked question about the suitability of using a "C" gearbox on the YG 4 engine. I copied and pasted his first post in this thread, gave him credit for it and also wondered why he is still helping people install "C" gearboxes. Here is his response.
"You wish to address this in the YAE group> bottom line - or rather your bottom line: "5 months later he (me) is still helping people install them (Rotax C) on their engines". Jason, that is terribly wrong and misleading, and the reason your posted quote was removed. You see, this is the first, one and only, not "still" Rotax C conversion I have ever done. I have Arrow, Air Trikes, and built my own chain drive ground up, and what we now market as the Mohawk SP Gearbox, based upon SPG4. Next, yes the quote you posted is 5 months old, and things have changed since it was written. After Steve and I spoke extensively and weighed all of our options we agreed together as a team to proceed with the new project using the Rotax C box for one reason - and one reason only: It is the only solution available to us today that will fit under the stock Highlander hood, and has nothing to do with any anything else. I am doing this to help him, it is his desire. If you are going to beat me up over it, fine, whatever. But don't act surprised if you find yourself censored when you play this game, and don't act like you don't know what I am talking about. The YAE group is intended to promote Yamaha engine conversions, not devolve into a personal platform for which to carryover from other hostile forums and environs any baggage you wish to bring here with you. I get it. You don't like me. I don't give a rat's ass, and the fact that you have never confronted me mono e mono with your personal feelings tells me all I need to know about you. If you continue to take a snide, back-handed approach like this to a perfectly innocuous, innocent, upbeat and news-worthy post as the one I uploaded above, you will very sadly and unfortunately find yourself on the outside looking in here and have no future ability to join in on any discussions or contribute your otherwise much appreciated and useful input. This post of mine and anything related to this sort of thing will be available briefly, and then it will be removed, and let that be the end of it.
I also received this private facebook message,
"The RWF quote you added as a comment was considered to be contrary to the YAE policy to maintain a positive and neutral attitude in regard to equipment, regardless of origin/manufacturer, for use with all Yamaha-related engine conversions in use and in development at this time. I think you can agree that the comments lifted from RWF were somewhat disparaging to Rotax gearboxes in general. It is not my intent to shed a bad light on Rotax gearboxes in YAE. I fell it would be best if you do not agree to contact me directly to carry this discussion further. Thank you for your cooperation, and more importantly for your keen interest and participation in YAE. You are valued guest, and as such your opinions and observations are highly regarded by all, myself included."
Since he is in control of the facebook page he is deleting all posts that don't subscribe his (and his companys) agenda. I posted an unedited quote of his and apparently it was too negative for the world he is creating over there, he deleted the post.
As always be careful of unproven claims of reliability and know that forums that appear to be public may be highly edited to reflect the interests of an individual or company.
Just another data point when searching for a (mentally) stable vendor.
FWIW
