harbinger data

Post by phil sellwood »

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,

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

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.

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!
Phil.
