Rubber is only part of the puzzle on an indoor model. Having 5/99 will
not take a 15 minute F1D and boost it to 25 minutes. I fly 10/97 almost
on all my models with the exception of a few models which I fly 3/02 as
I have rubber cut in the sizes they use. I have set records on these
batches and do well in competitions I go to without any 5/99 rubber in
my arsenal. The last batches of TSS I have been testing 3/2016, 6/2016,
and 3/2017 energy wise are quite good, equal to my 10/97 (actually a
little better than my 10/97) but to use it successfully you need to make
a loop the same weight but about 10% longer to get similar turns (as the
stretch ratio is a little lower) and similar torque to batches like
5/99. In a recent conversation with John Kagan on the TSS subject he
told me he did a 27 minute flight in F1D at Lakehurst on TSS (6/16) and
his loop was around 6.7" long which is about 10% or so longer than his
normal 5/99 loops. So the reason I am not doing 27 minutes in F1D has
nothing to do with 5/99 or Tan II etc he did it on current rubber. So
that means I need to sharpen my pencil and work on optimizing my model.
There have been really bad batches of Tan II in the past and my dad and
I have spent a lot of money and thrown out a LOT of rubber over the
years. Good and bad batches was just a part of indoor flying. You bought
5 pounds tested it , and hoped you did not waste your money. The next
batch you did it again and so on. The TSS I have been testing the past
year or so, the 3/16 and 6/16 batched and now the 3/17 batches all test
within a few percent of each other and equal to or better than my 10/97.
Is TSS going to replace 5/99 at the world championships anytime soon? I
doubt it, but for the majority of flying these current batches will do
just fine.
