Here we go again! My poor old EF 78 Extra has had the SAP, a Hacker electric, a Mintor 38. Now I am thinking of the OS 33 with a pipe. So, what header length, ES 30G or -40?

You won't go wrong....That's the true ticket on that airframe. Sure, not as powerful as the DLE55 I played with but with 25 pounds of thrust, it's got the most beans in its class.
Header length and pipe length the same as all other 30cc class set-ups. Either the 30G or the 40G. OR a canister
Okay Gang, Auggie was kind enough to video my Aesthesis/OS33GT/ESComposites 40G pipe combo. The main take away is the noise level from that well tuned and run-in combo. There are places where the wind drowns me, the geese drown me and a full scale flying a couple miles away does the same. The engine has around 13 gallons through it so far, well over 200 flights. When she's finally well broken in, the bearings are super slick. Compression is high and power output terrific. There is never a need to go to full revs in any part of the AMA Masters Pattern sequence....

I think I am done with this thread. Time to move on
