Hey everyone
I am going to build this plane as a #2 but i have heard it has a weak tailwheel assembly so could someone suggest a inexpensive, quality assembly that i can get from tower 4 it. Or a plan for a homemade one will do.
Thanks
Merry Christmas

help anyone???

DuBro .40 size tailwheel bracket assembly (375) & ¾" tailwheel (075TW). Combo will set you back under AUD$10-

Perfect replacement for the basic unit SIG supply with the Four Star 40. If you're the sort of guy who usually destroys or gets "bored" and retires a plane to the hanger wall within 30 flights, just use the stuff SIG supply. If you want stuff that'll tough out years and 100's of flights, go with the DuBro replacement and save the rudder hinge hammering for knife-edge & snap-rolls.

Probably the one thing I would definitely recommend is to replace the tailwheel. Make sure that whichever one you get will not put alot of stress on the rudder. The one Sigrun reccomends, (DuBro), is a good one or even the Sullivan brand works good as well.

Have fun with the model, I know I sure have a blast with mine....

Have had great luck with the Sullivan on a 4*60. Very forgiving on the rudder.

I've used the Sullivan tail wheel on several planes including my 4*40, they work fine.

Sullivan hardware is frequently 2½-3 times the retail price of Du Bro here in Australia, and probably in NZ where their dollar is at even greater disadvantage. This absurd pricing factor can make it difficult to source Sullivan stock off the local hobby store shelf for reasons which should be most apparent.

I prefer and use Sullivan hardware when Sullivan is superior and offers advantage. When not, common sense translated as local economic triage dicates Du Bro. In this instance, I used a Du Bro tailwheel assembly on my Four Star 40. Apart from the recommended DuBro items being more than sufficiently robust as well as lighter than the erstwhile well designed and constructed Sullivan assembly whose weight makes it better suited to a Four Star 60, who wants or needs to spend AUD$30+shipping on a substitute tailwheel assembly for a Four Star 40?

I built mine stock...so far it's doing fine...about a dozen or so flights on it(...actually it's my second 4*40... the first one flew through a tree!)...what I did do on this one was to make sure the fiberglass you wrap around the base of the rudder went up the rudder far enough to cover the whole area where the the tailwheel wire goes into the rudder. The first 4* had a tendancy to pop the tailwheel wire out the side of the rudder if subjected to too much sideways stress(ie.nasty groundloop on landing!).

Try the Sig tail wheel, it look good and works great.

Thanks every one. I will take a look at the kit when i get it

zimbo:
You can make your own using a good bracket and the "tiller" arm to protect the rudder.
Pictured below is a sketch of how the tiller is used to reduce rudder sensitivity when flying off of a smooth surface. In this case, the tailwheel turns only half the number of degrees as the rudder. If you want the tailwheel to turn the same degrees as the rudder "1 to 1 sensitivity", then locate the tailwheel pivot axis in line with the rudder hinge axis. You can use any bracket using this concept. The photo shows the concept on my sport aerobatic 40 size design.
