Double Star .61 Light
« on: August 20, 2013, 08:09:18 AM »
  Can you guys tell me your experiences W/the Double Star engine? I am interested in one after the success I've had W/the .54 .  I know they are out of production but they might be coming back. Maybe you have witnessed otherguys using them.                 John

I have extensive experience with the side exhaust but not the rear exhaust.  Not too many of the 61REs were made and those that I saw in service gave their owners the devil of a time with the run.  Tom's original 61RE in his Avanti used 7 to 8 inches of pitch and seemed to work ok, as did Andy Patterson's Avanti setup.  The rest that I saw were not very good.  The chief issue was that the engine would not burn more than 4 to 4.5 oz fuel and made about the same power as a Fox 35.

Norm Liversidge uses his with great success. I have not seen that motor give him a bad run ONCE! Set it up as per Tom Dixon and you'll never have a problem

   Thanks everyone,  I'm looking for a rear exhaust big bore engine. The Double Star looks inviting.

Ever considered a Ro-Jett? 51's, 61's, and 67's are RE and work great on pipe or RE muffler. Currently in production and supported. Joe Gilbert won the recent Albuquerque contest with a .67 on a pipe...high DA, gusty winds, lots of power, impressive. PA's too, if you can find someone willing to sell - I know I won't sell the one I have. ;D

I can answer a few of your questions: The .67 is currently in production and is the most popular Ro-Jett C/L engine. Order directly from Dub Jett, lead time is usually only a few weeks and he is very easy to work with. Dub also offers excellent support after sale. I don't wish to compare them to PA's which are also excellent engines. I like the .67 over the .76 as it has the same mounting holes as the RO-Jett 60 and 65...and PA's and VF 40/46's. 8)

I ran the DS RE in my modified Time machine for a while, yes a 7 1/4 pitch prop,sounded like a tractor LOL, but it later got to where it wasnt running consistantly no matter what I tried, pulled it and put in a Stalker 55RE, ran like a top.

  I have a Double Star .54 that started an odd way of running a while back, For no reason it would run richer as the flight progressed. I tried all my tricks & it didn't help.  One fine day it ran properly & it has ever since. I have no idea.
