Sapac Comp Hawk
can someone tell me if the stated c of g of 140-145 mm back from the bottom of intake is correct on this plane
as it seems very nose heavy for rotation with the landing gear installed
thx

RE: Sapac Comp Hawk
that sounds great Ron,mine seems quite heavy with the 4000mah pack,how much runway do you use?
I was thinking of bending the main struts forword towards the CG to help with rotation,my field only has about
300' of pavement

RE: Sapac Comp Hawk
Daryl ,
Rotation is not a problem .. I fly mine with a 4s 4200 and 5000 mah pack so your just fine with the 4000 mah..
but I will say 300' is going to be tight to land on... I've got maybe 60 flights on mine and I would have a hard time stopping on 300 ft.
it can be done .... but becarful
I fly at three site ones 1000' , 600 and 400
I use up most of the 400 on landing... maybe 200 to take off...
if you can use a longer site to get used to it that would help
I fear if you try and get it slow enough to stay in the 300' you'll stall.. so watch your speed
if it starts to wing rock give it some power
I hope it works out well for you.. keep us posted
later
