Dont listen to those tall tale mob, take a look at the ELA/ MTO/ Magni sleds, got the best safety record AND a lot more stable than those close coupled tall tale wobbler"s. The further back those feathers are the better. The reason tall tales are popular are for those who have small sheds and cant fit a decent length

Okay, so I"m seeing that the Tall vs. Short tail debate is a "Fords and Holdens" kind of thing?Nothing is perfect or ideal, everything comes at a price with its own up and downs, so you weigh up the factors and decided on what suits you best.Or as the old saying goes, "Yer pays yer money and yer makes yer choice!"Has anyone written up a good article/paper/discussion that compares the two, reviews the ups and downs and helps a builder decide?

I must have been asleep too during all the training I did in my old two place tall tail tandem. Engine stopped landings were never a problem.I guess it must have been designed properly??Brian the reason Roscoe doesn"t use tall tails is they are not sold at Bunnings.

I"d love to hear an expanded explanation of your tall tail/throttle use/Out of body experience, Max.What is happening and why does power use vary between the two tail types?Thanks.

I found that i had to bring the throttle up a bit quicker with the tall tail to have rudder control when the nose lifted. My rosco trainer requires a very slow throttle increase as it has no pre-rotator which is good for student rotor training. Plus it keeps the old girl light. The tail being a long way back answers when ever the nose lifts. As for the out of body experiences, it"s my only explanation for not remembering anything when I think I may be going to die! There seems to be a few seconds missing from my life. An atheist would probably call it adrenalin overload.

Ah, that livened the show up a tad !Okay, to my limited knowledge, tall tails originated out of the USA in a gyro called....wait for it, THE DOMINATOR [ dictionary says got to call it big in case it isnt

Up our way lots of the lads are proudly flying with small Bunnings aviation tails. One thing I"d like to know though is "Can a tall tail always enter a flat spin on command and always pull out on command?) If the answer is Yes, then I would be impressed. Iv"e been too scared to try with a tall tail, (and am proud of my fear)

Standard practise with students for me was to set up a full flat spin and get them to recover. Spinning to the left I could get it up to almost one revolution per second.No problem recovering by simply straightening the tail and it would stop within a turn.If you wanted to stop quicker a bit of opposite rudder.I know of no other instructor that does this and know of quite a few that refuse to go anywhere near flat spins.There is a clip on youtube of me doing a flat spin in a single seat TT at the ASRA Nats, I think in 96,someone may be able to find that and post a link.Unfortunately we have had numerous flat spin to the ground accidents with Benson type tails.Tall tails are designed to be placed as near to the prop as practicable,3 to 5 inches. The whole idea is to cut the swirl effect before it starts,hence cutting out P effect. Put a TT to far away from the prop and have the height smaller than the prop diameter and the effect will diminish significantly.People tend to see the tail close to the prop and not look at where the pivot point of the gyro actually is, and how far the tail is from that point. Any tail that can be up to 6 feet tall and have a chord approaching 2 feet has some serious turning force.Brian I think next time you come up we must do some serious flying in stable machines instead of sitting around and you drinking all my beer. ;D

I don"t think I could"ve stirred up a bigger hornets nest if I"d gone into some V8 Supercars forum and posed the question, "So, which is better - Fords or Holdens?":P

Gents, there are tall tails and conventional FW tails, and they are all there to do THE SAME job. That is to ensure the machine always points in the direction of relative airflow. As long as the tail achieves this, then the machine is safe to fly. Using technical terms, it about ensuring the machines CofG (centre of gravity) is always in front of the machines CofP (centre of pressure) A tall close coupled tail usually required a lot more surface area to achieve this than a conventional tail setup due to its reduced leverage. My only comment is that a tall closely coupled tail sitting behind a wide 2 place cabin machine can become shielded from the relative airflow causing a wobble during, engine off or idle power settings.My 2 bob Cheers SamL..................
