REWORKED LA46 AND TT PRO 36
« on: October 10, 2017, 10:59:13 PM »
I have a OS 46 LA-S and a Thunder Tiger Pro 36 that have both been reworked by Byron Barker. I would appreciate anyone having experience with these engines sharing their thoughts as to the comparison of them to box stock similar engines. I would like to run them in high-rev low-pitch mode.

Hi Guy. I have both engines from Byron. He liked the classic "4-2-4" engine run, and set up his engines to do that pretty well! I don't know if you will be happy trying to run yours in a higher rpm mode.

Get rid of them and buy a couple "stock" engines.  y1

My 2 cents, Jerry

BB re-works are set up for a traditional stunt run, not  for a high RPM/low pitch. For that, take Jerry's advice. Here's should you change your mind about the type of run you are looking for, here's some suggestions:

For the 46, start with an APC 11x5 prop, 10/22 fuel,  4.5 ounce tank, ground RPM from 8800 to 9200. At launch the engine should be in a 4 stroke, occasionally breaking into a 2 stroke. It will settle into a 4 x 2 break reminiscent of a ST-46. Not as much peak power as a stock engine but a quality run and a good choice for modern or classic stunters  from 550 to 610" sq.

For the .36, a few prop choices are the APC "toothpick" 10.5x4.5 (ground RPM 10,00 to 10,200) or if you can find one, Bolly Clubman 10.5x5. Ground rpm around 9800. 4 to 4.5 ounce tank, 10/22 fuel. Run will be very similar to the 46 but less of a break, especially with the APC 4.5" prop. FWIW: above info was acquired from actual use, not theory. .36 was replaced by an Aero-Tiger which I like better but the Byron Barker tuned .36 is a very useable engine and definitely a "keeper".  8)

Hi Guy

You can try them 4/2  and if your happy with the runs, then fine, if not, they can always be put back, I have sleeves that are brand new for the  TT 36  and  also have  P/S sets for the  OS, so you really are  OK either way.   There  is  NOTHING wrong with these retimed, as long as they were done properly and not taken too far
