Control settings & CG for Bretamodel Nyx F3b

[Baldrick]

Good Evening gents,

I have the chance of buying an old Nyx F3b (pylon mounted  3 piece 3.2mtr wing).. at least that's what I think it is

does anyone have the control settings and the C.G for it?

the ballast is a single steel bar weighing 472g

If the price is right - go for it !

I've got a Nyx F3F - if its any help:

This page has Nyx F3B - says 107mm for CofG - you can probably guess the throws etc - (run the page through google translate)

Should be a good all-round soaring machine

that's my thinking, what do you have your Nyx CG set at?....

just found this on the German RC.de web site

After some digging in the BARCS archives - for the Nyx F3F CofG I started at 110mm - then moved it back a bit. 

 

[Baldrick]

thanks,

             I will start at 107mm level on the rig & then fly a few  runs inverted and gradually adjust a small lead weight taped to the fuselage behind the wing until it only needs a whiff of fwd elevator stick pressure to keep it level.... 

[Baldrick]

then back onto the C.G rig to see where the C.G ended up, take the trim weight off, back onto the rig and remove lead from nose till it re balances.

Got a reply from Martin at Brett model today and he says to use the settings and CG from their current F3b model the Furio… now just need to get the Nyx
