Sims to reality

[DumbDawg]

I just wanted to find out some info from those actually flying their birds... AND have used sims as well.

I'm using heliX sim for practicing etc. When I bring the tail around the bird in the sim wants to drop like a stone. Is this a true factor when flying for real?? Something I'll have to add collective to when I'm turning or bringing the tail around even on a hover??

The sim is really helping in getting my brain wrapped around the orientation stuff but I'm thinking its probably out somewhat when it comes down to the physics of the actual flying model.

yes/no???

It depends on the heli. With some marginally-powered helis, a piro to the right (clockwise) will indeed cause the heli to settle a bit since it takes power to increase the pitch on the tail and yaw against torque. It shouldn't "drop like a stone" but it might settle some.

on computer TX's you can use the mix to cancel out the effect

What are you flying Dumbdog?

[DumbDawg]

I have a HBK2 and a small lama3 for indoors. I was just wndering more about the HBK as I'm not yet flying the thing around. Just learning to keep a steady hover right now.

[mnwizard]

Not sure about the HBK, but there are a couple for FMS of the Lamas that are pretty close.

Well I got the Lama because they are so easy to fly and its a great tool for me to help in learning the orientation thing. Its so far been pretty stable but for a few 4-in-1 glitches. I have seen where others have posted about these glitches as well. Not sure what the solution there is.

Any rate, the Lama is to help in teaching me orientation and something to fly indoors when the weather is crappy. The king is for learning 3d later and just generally having fun.

So I was asking mainly about the king and whether the sims I have are fairly accurate or not really. I'm using Aerofly amd heliX mainly. In these two sims the heli I'm using is the Picco because I'm told it is closest to the hbk2. When I make any tail corrections or piro's the bird drops, not settles but drops and I have to apply quite a bit of throttle. Hence the question, Is this close to what happens or just the sim is goofy.

I think I have it pretty much figured out now tho. Thx

A co-axial like a Lama will drop when using the rudder because it turns by slowing down one of the motors so the torque of the other motor will twist it. 'Course in a fixed pitch when you drop motor speed you lose lift, thus the drop. If you don't compensate with a little more throttle, the drop can be pretty quick, but I don't think it's as severe as what you're seeing on the sim.
