I wasn't clear. I should have said to add the weight to get the right CG.

SETTING THE CG


This has been mentioned before but is worth repeating. The starting CG setting on most gliders is a recommendation, not a law. That CG setting should get you safely into the sky. Then you tune.

My experience with most gliders is that the "stock" CG is a bit more forward than I prefer. But I still start from that point. It is best to work the CG back, over many flights, to get the best trim. What will work for me may be too rearward for you.

People post their CG settings, but if it is rearward of the stock CG, and you are not an experienced glider pilot, you may not want to start that far back. Just a thought.

I have flown gliders of very accomplished pilots were the CG is so far back I found it hard to fly the glider, but they loved it there. I have flown other contest gliders where the aircraft seemed nose heavy to me, but they beat me with that glider every day of the week because that is what worked for them.

Start with the specs, but leave room to adjust, usually rearward. If you put lead in the nose or tail to get the stock CG, leave some of it as easily removeable so you can tune the CG based on flight performance or based on your personal preferences.

If you are set up for electric flight and have several battery packs, weigh them. If your battery pack is not right on the CG, you may need to strap on some lead to even them out.

It was a surprise to me that the recommended C/G was so far aft. I've never owned an aircraft with the recommended C/G in that position. As you said, after that it is trial and error to find what works for you. Rick

This statement makes sense to me. I will work on it and see how it goes. Start with the specs, but leave room to adjust, usually rearward. If you put lead in the nose or tail to get the stock CG, leave some of it as easily removeable so you can tune the CG based on flight performance or based on your personal preferences.


Thanks aeajr

Good Camber Settings

I need help with the correct camber settings. The manual is confusing and first shows:
Speed: 1 mm up TE
Cruise: 1mm down TE
Thermal: 3.5 mm down TE

Then the next paragraph gives:
Speed: 1 mm up TE
Cruise: neutral TE
Thermal: 1 mm down TE

So the Speed is the same in both references, but which setting is better for Cruise and Thermal?

I was surprises to learn that E flight are out of stock on suggested props (march delivery date)? I wonder how they think can sell this plane without props in stock? Do any of you know of different prop to use with eflight .25 motor.

Thanks

Speed/reflex looks good. Use that.

Hopefully someone from HH will jump in but here is what I would do.

I think the first one is a missprint. Probably an editing error during the development of the manual.

Cruise is normally neutral surfaces. I would use that.

Thermal - 3.5 mm down could be the right setting for this airfoil for thermal. 1 mm seems too small. When I don't have a spec I usually use 2-3 mm down for thermal. I would go with 3.5 mm down.

Hi mertz,

No problem at all asking. Yes I did start this thread and I follow it daily. I am a little disappointed that here in Australia, we have not seen the Mystique ship, not a single unit. The ETA keeps changing. I am impatient I guess. Perhaps justified.

Also, I am funding some more immediate multi-rotor FPV projects and needed some cash to keep that going.

I am still very fond of the Mystique and like I say, follow this thread with great interest. I will get one, just not within the next few months.

Cheers.

I was wondering if it was due to availability issues. Just watch now you'll be able to buy one after you've sold all your stuff. That is how my luck works!
Have a good New Years!
