Posted 14 Aug 2018 There's a guy in ND that could help with that. Not sure where you are located? Share this post Link to post Share on other sites
Posted 15 Aug 2018 I'm in louisville ky. The fella in ND is William Langford. He has made up some FWF components for the Yamaha that fit the KF 4-7 and has offered to help with custom engine mounts.Problem there for you obviously is about 1000 miles!But dont be too intimidated with making your own custom mount. I had not done it before and (with some help and a lot of time) was able to tackle it:http://www.avidfoxflyers.com/index.php?/topic/5345-yamaha-genesis-rx-1-install-in-kitfox-5/&page=2 1 person likes this Share this post Link to post Share on other sites
Posted 8 Oct 2018 Thanks Yamma. I had Jim send the Apex to William. He's working on an engine mount, exhaust and other components for me now. Ian is doing the harness. 1 person likes this Share this post Link to post Share on other sites

Posted 5 Apr 2019 Dear all,Im just on my way to build an ASSO XRAY (wood air plane) from planes comes up to Guiseppe Vidor (Italy), its an side by side airplane and Im looks around for an engine that will fit to the airplane. Please see in the attachment the airplane when it is finished. So I just get in touch with your solution, to use an Yamaha RX1 Engine coming up from a snow mobile, but here in Germany this kind of toy is rare. So i hope will catch up some solution from your engine that is still running.Best regards Maxi 2 people like this Share this post Link to post Share on other sites

Posted 4 Sep 2019 (edited) I am looking for a quality adapter and gearbox for my RX1. Ideally, I would buy a system from Teal, but the supply may be a little slim right now. I need something that is proven to be reliable as my children’s lives are the most important, and I do not want to be a widower. Please make recommendations that you know to be reliable and robust. Thank you. Edited 19 Sep 2019 by Supermotive Changed content Share this post Link to post Share on other sites
Posted 18 Nov 2019 I accidentally came across this post... wow RX-1 engine in aircraft, how about I give you another idea:Yamaha MR-1 Engine (same engine as in snowmobile) can be found in most yamaha jetski's 2002-2008 yamaha FX or even VX and V1 2004-2015, also AR/SX Yamaha boatsAlready has reduction gear, dry sump oil system, water cooled oil tank, 160hp, you just have to come up with some kind of water pump for cooling.What do you all think?
