Anyone who has one of the Sbach, will this adjustable motor mount work (the dimensions required are in the link). I just don't have the plane to measure.

ryanbe 15, i dont have the sbach yet but i honestly dont see why not. compare stock motor mount dimensions to this one should give a definite answer.

somebody here could tell you surely.

iceaxe (cool name btw)

is this what you were talking about?

The SBACH my GF got me just showed up. I ordered Orange from the US warehouse and Orange is what arrived. I'm putting a few coats of polycrylic on it before assembling to help protect the paint from hangar rash.

Next question: This will be my first true aerobatic plane. Recommendation on EXPO and DR? I was thinking 45% DR and 30% expo till i get used her. Thoughts?

found this on page 81. great info there.

yeah i saw that in the manual. I'm worried it will be to snappy for me till i get used to it

are you flying it stock???? let me know if the electronics hold up. i hear that for being a chinese PnP its pretty decent. except for the motor throwing magnets.

I do plan to fly it stock for now. The servo's do look beefy.

Personal feeling: the manual's low rates are OK, the high rates need a little bit more expo.

Now that I'm more used to it I've increased the throws to max, but don't do what I did and run it on high rates on your maiden! Especially if this is your first aerobat. It's not that it's hard to fly, it's just surprisingly responsive for something that big.

rayonnar: My manual doesn't have the recommend low rates and high rates. All i see is that photo that out of stock posted.

Can you help me?

Hmmm, that page actually looks like the page out of the manual that I recall using to set up my rates. I think I have interpreted it wrong! What I used was, measuring from the TE of control surfaces, 15mm up and down for low rates, and 25mm up and down for high rates.

Those low rates were more than enough to fly my plane. If you're concerned about insufficient control authority, you can set the movement slightly bigger but dial in more expo (40-50% maybe), just be aware that this will make the end ranges of movement much more abrupt.

check out page 78 post #1159.

or maybe somebody has something better? i'm interested in knowing what are the best rates.

Ok think i'm following.

High rates are 25mm (25mm of movement)
Low Rates are15mm (15mm of movement)

40% Expo to deaden the sticks. That makes sense to me.

rayonnair, low 15 up/down and high 25 up /down sounds about exactly what i would do.

I suspect the "best" rates are whatever you are most comfortable with. Just give yourself a safety margin. Otherwise you will see what happened in my post no. 1150, haha!

I had hoped to have it all together tonight but would appear the screws for the elevator are too short. Off to HomeDepot after work to find bigger screws tomorrow. Anyone else have this problem?
