I just uploaded the details of my tailspring installation in the photos section under Bergen's Tailspring. Hope this is of some benefit.

Lotsa tailsprings broke in the early years. This was covered in early newsletters.Speculation was tail swishing on landing due to pilot control (side loads). We didnt hear that problem from Dfly pilots (broken tailsprings) due to the oval shape horizontally we thought. Those fiberglass rods were available from Aircraft Spruce Co. One of our guys fixed his using a readily available 4130 steel tube of the original diameter.We didnt get a followup report on how that worked but that's what I would use lacking any complicated mathematical engineering calculations to prove otherwise. j. -----Original Message-----

I now have a 3/4 inch commercial S glass solid rod pultrusion which also allows it to be made longer so it can be extended in line with the rear fuselage centre line. Mine is just over 1 foot and effectively retracts the tailwheel in flight as it sits in the fuselage drag wake. By the time you have added the several plies of uni and bid staggered to the tailcone, it will be over 1 inch diameter after finishing. Looks like it can do the job and does it and at reduced drag.........suggest you take note. Dragonfly tailspring is oval with the widest cross section the wrong way for loads in my opinion. A circular cross section is better I think.

There is no tail post. The fin (vert stab) is built like the main wing with spar caps on both sides, and then floxed into a slot in the tailcone. Do you not have the so called 'building instruction's ?' Paul Buckley Cheshire England Embryo TriQ-200 ----- Original Message -----

Sent: Monday, January 21, 2013 10:22 AM Subject: [Q-LIST] Tail post Hi all Can anybody tell me what the original tail post was made from as I didn`t receive one in the kit that I have. Are there any plans around so I may be able to construct one, or could I use something like a carbon fibre seat post from a push bike? Thanks Ray. |
