    Subject: 912ULS to 914?
    Dear All I am struggling to get out of a 450m grass strip 2 persons and full fuel (no baggage). Has anyone got experience of the improvement in take off performance with the Rotax 914 over the 912ULS? I expect this has been debated before but I cannot find a way to search the matronics website for it. Thanks William Bliss G-WUFF Mono Classic XS firewall forwards. 912ULS, Woodcomp SR3000, Smartcontroller

    Jerry, That is interesting. Thanks for sharing. I have always considered a fuel vent facing forward was not a safe enough solution, as water and dirt (even bugs!) may enter in flight, being pushed by the airflow. Therefore I have added a second vent which exits vertically at the bottom of the fuselage. The two vents are connected with a tee. Additionally, I have covered the top vent with a stainless steel screen. The bottom vent is also convenient when filling the tank as it allows excess fuel to flow out before the cobra is filled to the top.

    Hi William, I have experience with the 912UL, the 912ULS as now fitted to my aircraft and some time in a friend's Europa with the 914, which I flew for the initial issue of its permit and subsequently. Subjectively I can assure you that the extra 15 horses in the 914, available for take-off for a short period, are very noticeable and possibly shortening the run by something like 10%. But I wouldn't want the 914 for my aircraft, partly because it's much heavier and also there are questions in my mind about its reliability.

    William, I have never had any trouble operating from a variety of 400m strips with my XS/914/WoodcompSR2000 or SR3000W combination. There is also a considerable benefit if you want to fly at altitude as it gets more efficient the higher you go effectively. As to reliability the older versions had a tendency for the waste gate to stick if you used Avgas in particular, but this was not too serious - it effectively left you with a fixed manifold pressure, and a 30min job in unsticking it. I have not had any other reliability issues with mine in over 1000hrs. Having said all that I am not sure that I wouldn't go for a 915IS if starting again.

    I have a similar set up to you and fly from a short strip, I seem to be unstuck in 200 Meters or less, are you sure your prop is setup to go fine enough? Do you have the wide blades? -------- Graeme Bird G-UMPY - Mono Classic/XS FFW 912S, Woodcomp 3000/3W CS, trutrak Gemini 2 axis ap, pflarm, ads-b out, 8.33khz, mode S, FP 5, Aera500 &amp; SD on Nexus, 250 hours &amp; 4 years on the Mono, 880 total g(at)gdbmk.co.uk Read this topic online here: http://forums.matronics.com/viewtopic.php?p=460571#460571
