can anyone help. I'm just starting a 1/4 scale harbinger and the plan has no CofG, no datum line, no incidence angles and no control throws!
CoG is the important one. I shall plump for strut position/ wheel axle, if no-one has any experience with this prototype.
here's hoping,

Re: harbinger data
Hi Phil when I had one it balenced bangon the wheel and flew very well on it. Cannot remember the control throws.

Re: harbinger data
Phil,
Full size control throws are on the attached BGA data sheet.
As long as you have enough then you should be able to fine tune from there.

Re: harbinger data
hi guys,
thank you so much for the info. I haven't started the build yet but it's nice to have an idea of where it balances so the radio can hopefully go where I want it not where it must go- hate using excess lead!
