Nice little airplane. One issue, I can't seem to get enough up-elevator authority at slow speeds; I'm not able to flare for landing or perform power-off stalls. Has anyone else had this experience? Thanks! Yep, just like JetMann mentioned, I found elevator trim to be the limiting factor with pitch up as well on my landings for the flare. Once I added in more up elevator trim than I initially thought it would need, I was able to flare just fine and keep the nose up for stalls etc. Reminds me of the Piper Colt I used to own, that sucker needed a ton of nose up trim added on final to get a nice smooth flare. Otherwise, it simply ran out of elevator authority. Good luck and have fun!

I have actually run into this once already as well... I didn't try and take off from a gravel runway, but landed on a back country area near a river in the great Bella Coola scenery. After landing and stopping, I could under no circumstance get the EuroFOX to move again. Tires were fine (no XP blown tire warnings like you can get after a hard landing), was a soft/smooth landing. It was literally glued to the ground. Brakes on/off, full throttle, flaps up or down, rocking with controls etc, nothing got it to move. This was in XP10. Otherwise, has been a great aircraft and experience! Thanks again and look forward to future versions! Hi! Thanks! I have noted your "wird behaviour on countryside terrain" report. I will check it out soon. The landing gears are of a standard type, without any design "improvisations" on my side...have you tried to land in the same spot with other aircraft? Anyways I will run thorough tests with various models and will report upon the upcoming update. Thanks again! eulereit, thanks for your note about the trim: this "flying practice" of the current Eurofox version still needs a fine tuning process...so the "feel" might change a bit as the aircraft development continues.

Nice little airplane. One issue, I can't seem to get enough up-elevator authority at slow speeds; I'm not able to flare for landing or perform power-off stalls. Has anyone else had this experience? Thanks! Hi eulereit, Thanks! Are you using the elevator trim? I've flight-tested the model and tuned it so if you are coming in for a landing and set the engine to idle prone to the flare, and then holding it up, the aircraft will touchdown in approximately 45-50 knots, as it should be in the real aircraft. This maneuver requires a proper setting of the elevator trim. The only suggestion I have for the moment is to check your trim settings (set it up with the joystick button or other key). While trimming look down to the trim handle between the seats and see if it moving up/down. Same goes to power-off stalls. Note that the aircraft in its current version is setup with a mid-forward c.g. so the use of trim is required. The reason is because the light aircraft is quite sensitive (in X-Plane) to pitch moments, and I wanted to ease up the pilot workload in straight and level cruise. Anyways, the flying characteristics of the aircraft are still prone to some changes, as the aircraft is getting "mature" (development wise) every day Yes, I had full nose up trip with throttle at idle. Granted I was approaching on the slow side (50 mph), but I couldn't flare or even get it to stall. I'll fiddle with some of the realism settings and see if that makes a difference. Thanks!

For what it's worth, I am not experiencing the flare problem mentioned here. For me the landing behavior seems to be pretty much as expected. I'm on a Mac in XP11.

Glued to Gras and Gravel also happened to me, On xp 11 and newest iMac27" with all in. No escape. Changed the fuelconsumtion via planemaker similar to the Remos. Reduced the Prop Blade angle a bit to achieve Full power during take Off. Now 5200 rpm with TWO. Results are more realistic behavior: 2.8 gallons with 85 Knots and 4800 rpm. The plane behave much as the Original. Real Nice!

The plane behave much as the Original. Real Nice! Hi! Thanks for sharing your settings.This kind of feedback is very important. My goal in the rpm issue is to find the "golden path" between low and high airspeed propeller and engine performance. There is a limited sized "blanket" to cover a wide range of performance aspects, so while having the rpm higher while the aircraft is static or at low speed, we might end up getting an aircraft that accelerates faster than we would expect, and at the same time having a reduced maximum airspeed or cruise performance. Tuning process of engine/prop systems in X-Plane is a sisyphic process, and each time a specific sets of variables are being analysed, for example, you can get a higher rpm either by setting the overall pitch of the prop (designed airflow/rpm), or, the specific pitch gradient of the blades, or by setting a higher maximum throttle coefficient etc... This is the reason why engine, prop, cruise and other performance aspects will be fine tuned during the next two or three updates. Grass and gravel issue is under tests as we speak. Hopefully the first update will be released by the end of the upcoming week. Thanks again for the precious feedback! Keep it coming

I can't say that I've landed at this "exact" spot before, but I've done quite a bit of off airport landings/takeoffs in this same scenery area (Bella Coola) in other aircraft (mostly the Soulmade Sim DH-2 Beaver, a few of your Trikes, as well as your Ultralight Bush Plane) and none have had this issue of getting "stuck". I should have some time later today to play around with the EuroFox some more, and will let you know if I notice any sort of trend or anything. Take care. Thanks for looking into it!

Just to follow up my last post, I loaded up XP10.51 with the EuroFox at Bella Coola, took off and then landed on a grassy field about a mile away from the runway. Landing was fine, rollout was fine, but once I get stopped, the EuroFox simply won't move anymore.
I can gently rock it or move the nose with the rudders and full throttle, but it simply won't roll or move forward.
For comparison, loaded the DH-2 Beaver, took off and landed in the exact same grassy field. Stopped, sat a minute, then was able to move again and take off normally.
By no means complaining, just following up with feedback. Have a great weekend!

Hi be77solo,
Yes I've got this minor "bug" fixed for the upcoming update. The short answer is gear friction coefficient settings. The longer answer is that it affects other performance aspects so there are some other variables involved...anyways, any kind of feedback is inspected carefully and also very appreciated!
Great weekend to you too buddy:)

I'm now getting the itch for the Autogyro package.... :-)

Nice little airplane. One issue, I can't seem to get enough up-elevator authority at slow speeds; I'm not able to flare for landing or perform power-off stalls. Has anyone else had this experience? Thanks! Same happened to me. The Original Aircraft has the Ability to fly with 65km/h or 35 kts with full Flaps. Its designed to fly with 120 km/h or 65 kts with Trimm in neutral. Flaps should not used above 58 kts. I don`t know the Difference between IAS and TAS in the X-EFOX, but the actual Configuration is not really able to fly level Power off below 107km/h or 58 kts even with full flaps. Nose goes down, doesn't matter how far its trimmed Nose up. For the Fuelconsumption and the Propgeo see the attached Fotos. For me this works.

Hi tarutino!
The X-EFOX can fly in 35kts with full flaps. Note that the airspeed in the indicator is for MPH, so you can fly in about ~41-42 MPH with full flaps (it is almost 'on the stall').
Thank you for sharing your prop and fuel settings. Note that if you will only change the prop's pitch in the current configuration, you will have difficulties to obtain cruise speed at engines operation limits for cruise. In the upcoming update (by tomorrow it will be released), I've tuned the aircraft one step further. Will be happy to get your feedback again!

Hi JetMan, sorry, i thought the ASI shows KTS ;o) This changes something.... Awaiting your update!

Wonderful update. Seems to fly with a bit more finesse. I Like the ASI and RPM gauges. Thank you for the update and I look forward to many fun hours in the fox.
