Grasshopper Posted November 28, 2014 Share Posted November 28, 2014 FireFly question. I have dug my FireFly out of the back of the hanger and started to check it over. I find that with no LiPO the hang angle is 22 deg. and with a 3S1800 it is 27 deg. The only way I can acheive 16-18 deg. is by adding 75g os so of lead to the tail which seems wrong. Any suggestions please? Peter Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted November 28, 2014 Share Posted November 28, 2014 Peter, I have not come across this before, can you take a photo of it hanging please? If it is this much it will be nose heavy, without adding tail weight the rotor axle would have to be moved forwards which is what I would do under these conditions.

Grasshopper Posted November 29, 2014 Share Posted November 29, 2014 Rich, I have carefully measured the mast/boom angle and it is 10 deg. - the plan I measured as 9 deg. I assume this is the target value? I broke the original mast in a bad landing and had to dig out the base section. This error will lead to some latent additional hang angle, nose down but not the value I found this morning. When hanging as shown with no LiPO I measured just under 25 deg. between horizontal and the boom. In the nose is motor 2837/18 = 79g plus 30A esc. Any thoughts on a work-round?

Richard Franks Posted February 3, 2021 Share Posted February 3, 2021 finished my El Bandito now looking at a firefly ..only got 5mm to make fuslarge sides and cannot source any 6mm at present.. will that do?Also got some spare blades from previous Burky builds they are a little longer both length and chordwise will they be OK ? Any thoughts Richard Franks Quote Link to comment Share on other sites More sharing options...
Richard Harris Posted February 4, 2021 Share Posted February 4, 2021 Richard, Using 5mm balsa will be fine, as for your blades they should be ok though may give you a little bit too much lift. Good thing is they are longer so you can always cut a little off them to suit the Firefly. If you get chance take a few photos along the way?
