Problems with taking-off occilations

[nickpauly98]

Hi all,

I love the idea of the game but haven't been able to take-off. Both using full assembly and quick start. After starting up the engines succesfully, I can barely keep it in a straight line. I tried using differential thrust and yaw input. after many full drifting turns I can go in a straight line, but as soon as the plane reaches 50 kts it starts bobbing up and down losing all of its speed. I am using a T.A320 joystick but keyboard/mouse controls give the same result. This is happening both in the regular and beta version.

Seeing as other people have flown succesfully it seems to be an isolated issue. Still I was wondering if other people experienced the same and how they resolved it. I tried recalibrating the controls, and the UI is very intuative, but nothing seems to have a meaningfull effect. Thanks! Hopefully this will be fixed :)

so, my suggestion is to use trim, especally rudder and elevator trim to help smooth out the flow, likely you have too much nose up trim causing the oscilations.

[zaphat]

do you straighten the plane at 50knots so that only the main body touches water? For me that was the key: it needs precise control on all 3 axii until airborne.

I'm no pilot, as evidence by: .... I have the same problems, too p:

But I've been looking into real takeoff procedures and the elevator trim needs to be set to a pretty nose-down setting for takeoffs.

Some GA planes that I saw have a marked takeoff setting for the trim, but we just have to guess. I'll be trying to fly again today after my yoke and quadrant arrive, and I'll be trying a 3/5ths nose-down setting on the trim first.

Another mystery for me is the takeoff and landing/final positions for flaps. I'm sure that I can figure it out from the checklist if I look up some details, but I haven't yet. I've been waiting to get the yoke first.

It's interesting what you wrote: for me the opposite works best. Even a full nose up / pull back trim works better than any nose down. As long as I level the wings asap of course.

Did you look at land GA procedures? Because I know with water based planes the goal is to get the engines as far from the water as quick as possible once they are running. Maybe this justifies different setups, but I am just guessing here.

It's a little difficult to get information for water GA thanks to search engines using AI to get as generic of results as possible (so land GA stuff...)

But anyway, videos I've seen of takeoff for float planes seem to trim for takeoff, pull back on the yoke until speed is gained, then put the yoke in to stay level until they reach takeoff speed.

I have been fighting the PORPUSING as well hahaha good times.

Trim is the way to go. In fact after 13 hours I never use the yoke, only trim (take-off, cuizing, landing)

For take-off, I trim all the way down (minus 2 notch).

I find it impossible to take off, even with trim.

Be in control and agressive with the plane, don't let it fly you.

- What ever Flap you desire.
- Nose raised by holding the Yoke FULL back.
- Hold your aileron to the right.
- Throttle up.
- Once the plane becomes active and starts dancing, dance back with it.
- Keep the plane level with the ailerons, keep the pontoons off the water.
- Keep the plane straight with the rudders.
- A stable and controlled plane, is a cooperating one.
- Again, be aggressive.

So just in case this gets anyone else...

I was having the same oscillation issues as reported above. I followed all instructions, reviewed the hints in this thread, and still had no luck. I had fully calibrated my Vkb rudder pedals and STECS throttles and my Thrustmaster joystick when key-binding and was about to give up when I found my issue:

I believe there's essentially a mismatch between the expected flight controller of a yoke, and a joystick, because my Y axis was inverted--pushing forward (down) on the joystick caused the plane to ascend, and pulling back/up caused it to descend.

If you are using a joystick and haven't checked this yet, I suggest you do. I only happened to notice it by catching the mismatch on the control animations--and considering the field of view for the game is somewhat narrow, you may never end up looking at the controls when attempting a take off. I inverted my Y axis and took off immediately. Hope this helps someone!

I can confirm that using flaps, having a fair amount of nose up trim (meaning the indicator on the trim gauge is about halfway between the neutral mark and the bottom) and using a combination of rudder and ailerons to balance the plane to get both of the wing floats off the water after gaining a bit of speed more or less fixed this issue for me.

Any chance for a Video of you just using Rudder and Aileron with having the same issue?

I honestly think it is simply because people aren't keeping it straight and level [even if they think they are]. I don't have to use any cheesing such as Flaps or Trim, I just keep it straight and level with no issues, and I am someone who also suffered Occelation at the start of playing.

I think if people with this issue start posting video's it would be much easier to determine if it is an actual bug, or just simple skill issue.

- Flaps as desired, Yoke Back, Aileron Right, keep it straight and level, is all you should need to do, no cheesing.

Here you go, but it's showing you're correct. You don't need either flaps or extra elevator trim. You just need to make sure to be pulling back on the yoke the entire time. I'm guessing that a lot of the confusion is that many are used to not pulling back with land takeoffs until you're actually at the speed for the takeoff rotation.

Cheers for the response and testing, and good to know that it is simply confusion [although I will never rule out issues don't ever occur].

It isn't uncommon in Aircraft to hold the Yoke full back when starting the takeoff roll. This ensures that the props are kept away from striking any waves or any pontoon nosecones digging in. However, as you start to gain speed, you would also slowly reduce the elevator.

The game is certainly "Gamey", but it does indeed try to replicate real physics to some extent, and it's just a matter of finding the current balance and providing good decent feedback to enhance our experience =]

EDIT:

Forgot to say that I like the colour of your Plane!

[Zielgan]

Thanks! Did a bit more random testing. I wanted to find some settings for when you wanted to travel on water as if you were using the plane as a speed boat.

It seems like using full nose up elevator trim, going full prop/throttle until you reach about 60 knots, and lowering the throttle to about 80% works pretty well. After that you can find your balance and adjust aileron trim to help keep it level without much input from you. If you turn and lose speed, you'll need to put the throttle back up until you get the speed back.

I also messed with the idea of using autopilot to maintain balance. It actually works pretty well if you help it find the initial balance and are going in a straight line.

Here's that video.
