Kevin Fairgrieve Posted August 21, 2016 Share Posted August 21, 2016 I have been given a 95% complete Ben Buckle Elf. Nowt wrong with that, and if I can find one I want to put a 48FS in it. The builder (unknown) has built in far to much dihedral. Or so it looks to me. Can any one help with the angle required and also the length of the cabane struts.

MattyB Posted August 21, 2016 Share Posted August 21, 2016 Doesn't look that much more to me compared to a few seen online... Unless you are grossly offended by it's looks with the current dihedral I would just cover, fly and enjoy it - it is not like this is a machine you will be trimming to the n'th degree for optimum performance!

Kevin Fairgrieve Posted August 21, 2016 Author Share Posted August 21, 2016 Now I have seen that I feel better about the angles. Just need to know the cabane strut lengths, and that would tie it all in nicely. Kev Quote Link to comment Share on other sites More sharing options...

GONZO Posted August 21, 2016 Share Posted August 21, 2016 Would a copy of the plan help **LINK** Quote Link to comment Share on other sites More sharing options...
bert baker Posted August 21, 2016 Share Posted August 21, 2016 I test flew one a year ago. The struts were a pain, if you over speed the airframe and pull a bit to tight the wing lifts and they fall out. Flew nice but don't over do the speed it can bite. The strut length at a gues is set when the wings are securly in place, make the dowles that form the leading edge if I remember right, as long as possible. Bert I think the chap who owned it was going to fitt a dowle in the wing leading edge to stop it lifting. Never seen him or the plane again.

Robert Foreman Posted August 21, 2016 Share Posted August 21, 2016 Kevin, Hold on, that link is to a plan which is not the Ben Buckle version, it is an updated version with ailerons and removal of free flight design points. I have the real Ben Buckle plan and it shows 2.75" under each bottom wing tip and 3.25" under each top wing tip. Regards, Robert Quote Link to comment Share on other sites More sharing options...

Kevin Fairgrieve Posted June 5, 2020 Author Share Posted June 5, 2020 2016 really. As I have been furloughed from work for the last 11 weeks, many projects have been progressed at an alarming rate. The Elf hit the bench last week. Just a couple of jobs outstanding. Paint the cowl and undercart, fit a throttle servo, a little trim to break up the white and then go fly. I am back to work Monday, but I am sure it will not be another 4 years before an update. Quote Link to comment Share on other sites More sharing options...

A 48FS is just a bit to big to fit. So I got a lovely little 40FS instead. Quote Link to comment Share on other sites More sharing options...
