thunder tiger 36 engine

[Bootlegger]

  I did a search on this engine and can't find the info that I want.
 Guy's that use this engine please respond, as I want first hand info.

 Where can I find these engines, and are parts available for them?  Does extra work (engine man) need to make them more stunt friendly?
 What fuel, props, glow plugs model size and weight, line length and ANY other info that will  help.
 I am in the South and we have 98-100 degree days as well as humidity ranges from40% thru and including 100%, so you can see the variables are there.

  And THANKS...

The Thunder Tiger Pro-36 can make an excellent stunt engine.  It's light and powerful.  It's the basis for Randy Smith's AeroTiger 36.
Most certainly Randy Smith changes a lot of things including using a AAC piston and sleeve.
But the stock engine can be easily made into a very good engine for our purposes...No it won't be as flexible or run as well as an AeroTiger but it can be a very useful engine for Classic sized airplanes.
In stock form it's an R/C engine.  To use it for CL Stunt it requires a Venturi and Needle Valve Assembly.  Either a ST or Aero Products available from Randy Smith or Jim Lee (Lee Engineering on the Forum).
and a muffler available from Randy S. or RSM.  It needs to run in a wet 2 cycle with low pitch props, like a APC 10.5-4 or 11-4.

Steve Moon used one of these in a G. Nobler for a number of years for Classic Competition and did very well with it.  I have two of them and both run very well.

Searching Tower Hobbies disclosed that the engines were not listed (not sure what that means), but all necessary parts were listed.

Of course if you really want to go first class one of Randy Smith's AeroTiger's is a more expensive option, but the very best standard of small light stunt engines.

The picture below shows one of my Thunder Tigers with a venturi and Aero Products Needle valve assembly and a tongue muffler (I think from Randy Smith).

I used this engine for several years in Gieseke Noblers. Great motor!
When I got mine they sold for $69.95. I then got a NVA and venturi from
Randy Smith and a lightweight tube muffler from Richard Oliver (also
available from Randy). I had local engine guru Glen Reasor do a little work
to it, but he said it didn't need much.

My G Noblers ranged in weight from 44 to 48 oz and the motor had no trouble
at all hauling them around. I used a Bolly 11.25 x 4 CF prop. At launch, the
motor runs just short of a steady two cycle. I used 59' lines.

If you come across one of these, I'd say go for it. They run great, very steady
and can be made to run great with little or no reworking. The G Nobler, TT 36
were a potent combo for me. I flew at 3 Nats in Classic, finishing 5th, 2nd and 1st.
Flew it at two VSCs finishing in the top 15 both times; don't remember the exact
placings.

I have one of these in a full bodied Cavalier, & it seems to be a very reliable & easy starting engine, AFTER IT IS BROKEN IN. It was really a tight engine on the stand at first, but began to be more tractable after 3-4 runs of 4-5 min. Someone asked about this engine 4-5 yrs. back on the forum, & one user said it takes a very long break-in period, maybe several hrs running to get it really broken in.  Ed

Gil I have the booklet that came with my Pro 25 and it covers the 36 and several others. It has specs and recommendations, break-in procedure, etc. No parts list though. If you want me to copy it and mail or e-mail it to you, PM me your mailing preference and address.

  RknRusty, I sent ya' a P.M

[RknRusty]

Done.
I found the PDF files for the owners manual and parts list for all the TT Pro series engines. If anyone else wants them, PM me your e-mail address and I'll shoot them to you.

EDIT: Ah crap it kicked my e-mail to Bootlegger back. Probably the file is too big. I'll try to sent the relevant pages later today.

   The only thing they need is a NVA & Venturi  they run great out of the box.

[Ward Van Duzer]

FWIW:

Randy can do a re-work with stock parts that will make it run like (almost) an Aero Tiger. Recommended by Ward-O! (Ask Gene)

I run them box stock on the Aero pipe either on a profile with a side manifold, or in a full bodied ship with a side-to-rear manifold. All parts available from Randy!

 Guy's I sure do thank y'all for the info, now what size venturi and needle assy are y'all using?
 I plan to use Power Master 10-22 as well as Sig 5 and 10-20.
 
  Again THANK'S and thanks to Sparky for this forum...

Gil: If you're going to be running it muffled, rather than on a pipe
I would recommend 5% nitro, or less. I tried mine at first with 10%
and it was too much. 5% was better, but mine always runs best
with 2.5% nitro Sig fuel. I just mixed Sig FAI fuel with Sig 5% to
come up with the 2.5% number. I was told by several people in
Tucson that just wouldn't work. I just politely nodded my head and
went about my business putting in one successful flight after another.
