Philip Lewis 3 Posted September 11 Author Share Posted September 11 I hope so too Peter, maybe Friday maybe next week, I did take it out for its first drive today to carry out a proper range check, all good (obviously). 1 Quote Link to comment Share on other sites More sharing options...
Philip Lewis 3 Posted September 16 Author Share Posted September 16 Maidened today, no drama, no issues, actually needed about 1mm of down elevator to fly straight and level so I'll set to work on dialing that out on the horizontal stbiliser incidence adjusters. 3 Quote Link to comment Share on other sites More sharing options...
Peter Jenkins Posted September 16 Share Posted September 16 Sounds like another successful F3A setup from the word go with the exception of the need to tweak the tail plane to lose the elevator trim. That seems to be a disappearing feature in the BJ Craft range. You just have to put up with a deflected elevator. At least the aileron trim can be taken out with the incidence adjusters.

Philip Lewis 3 Posted September 16 Author Share Posted September 16 These are the other way round, being a bi-plane it's not possible to adjust the wing incidence at all, that is fixed so the incidence adjustment is in the horizontal stabiliser instead. Good to have got the first flight nerves out of the way though, C of G as specified seems to be perfect, quite unusual, I normally have to move it back. 1 Quote Link to comment Share on other sites More sharing options...

These look excellent. Where did you buy the alloy couplers and the ball raced linkage? Also, why no ball raced linkage on the servo arm?

Philip Lewis 3 Posted 17 hours ago Author Share Posted 17 hours ago Hi John, You can get the alloy couplers from quite a few places such as Nexus but I got mine from MP Jets because you can buy both left hand and right hand threaded from them to create a turnbuckle, simply glue the carbon in using medium CA, carbon really glues well to both metal and wood with CA. Ball raced links I got from Ali Express. I find Ali Express very good for small obscure parts such as the type of canopy latch where the pin can't slip back in the control pin, I also get anodised coloured washers from there. You can't really use a ball raced link on the servo arm as that end is moving in two planes meaning the end would need to turn as well as bend up and down, it's not much but it's definitely there.
