Bill3558 Posted May 13, 2022 Report Share Posted May 13, 2022 What a difference. My vibration issues are gone. Picked up about 2-300 fpm on climb out, turning 5100 rpm. WOT level flight was 125 knots at 2300 rpm. ( took a while to creep up to that)Picked up 5 knots. So still over pitched a tad. Would you guys worry about 200 rpm? I don’t want to lug the engine. Engine starts and shuts down smoother too as others have mentioned. Old prop was 32 lbs. this one 14. I am very pleased. Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted May 13, 2022 Report Share Posted May 13, 2022 If you can only get 5300 WOT then I'd make the small adjustment. Climb and cruise should increase even more. Quote Link to comment Share on other sites More sharing options...

Neuform should be about 12lb with hub and spinner, e-Props is 4.4lb. Quote Link to comment Share on other sites More sharing options...
Bill3558 Posted May 14, 2022 Author Report Share Posted May 14, 2022 I’ll check the new weight and balance. My memory may be incorrect. Quote Link to comment Share on other sites More sharing options...
Bill3558 Posted May 14, 2022 Author Report Share Posted May 14, 2022 Roger Lee, I saw an old post of yours on Rotax Owners that 5300 rpm for level flight was the sweet spot for the iS. So am I there? I. Must say it felt good. Quote Link to comment Share on other sites More sharing options...
GlennM Posted May 14, 2022 Report Share Posted May 14, 2022 I have mine in the office! Waiting for new engine to install it on in August. Quote Link to comment Share on other sites More sharing options...
Madhatter Posted May 14, 2022 Report Share Posted May 14, 2022 E-Props is very specific on having 5500 rpm wot. Being on either side of that reduces performance. This prop is not like others. Quote Link to comment Share on other sites More sharing options...
Skunkworks85 Posted May 15, 2022 Report Share Posted May 15, 2022 Waiting to see the results of the MOSAIC Rules but this is what I'm holding out for, 8.8lb constant speed. Quote Link to comment Share on other sites More sharing options...

I'd be leery of it, but you can sometimes find a 500-800 hr 914 on barnstormers for 10k-12k Quote Link to comment Share on other sites More sharing options...
Towner Posted May 15, 2022 Report Share Posted May 15, 2022 I know a few CTs were built with the 914. When it’s time for a new engine, can my 912 be replaced with a 914 if I’m not experimental? Quote Link to comment Share on other sites More sharing options...
Anticept Posted May 16, 2022 Report Share Posted May 16, 2022 The 914 increases horsepower to 115hp, which is a problem for the 120 knot limitation. In addition, the investment in the 914 has stopped, and production will stop or has stopped (can't remember the date on the announcement). It will continue to be supported, but you will have difficulty getting a new one. The focus is on the 915 now. Quote Link to comment Share on other sites More sharing options...
Towner Posted May 16, 2022 Report Share Posted May 16, 2022 Thanks for the info Quote Link to comment Share on other sites More sharing options...
Anticept Posted May 16, 2022 Report Share Posted May 16, 2022 I remember what the announcement was now. Once the ECUs used in the 914 run out of stock, that's it. The 914 has always been a bit of a problem child, since it is a 912 with bolt on modifications. Rotax wants to be done with it. Quote Link to comment Share on other sites More sharing options...
