I just bought a boomerang assembled but never put in the air. It has a Wren MK3 on it. How much down thrust are you guys running on the turbine. This has 6deg down thrust this seems like a lot. I would think they would run 3 to 4 deg. Thanks George

Just leave it as it was designed...they fly great that way....

That is correct. none is needed.

Agreed. Mine has zero thrust, and flies terrific at all speeds. Check the stab incidence though. I had to shim my stab to achieve zero degree indicence to the wing.

Cheers,

George,
Ed ask me about downthrust and I think he missunderstood my answer. I have flown with zero and with about 2-3 degrees. I don't tell that much difference in flying, but currently I have about 2 degrees mostly to keep the heat off the bottom of the stab.

I also covered the bottom of the stab with alum. tape after I burned a hole in the covering with a hot start. I now use a start up metal tube to protect the stab during start.

My first 9 flights were in Dallas and used the recommended flap travel. When I brought it to Denver I cut the flap travel to max lift. Then it floated too much on landing and now since I have gone back to recommended flap travel there is now no pitch change from flaps full up to full down.

Thanks Sid and others
Sid I am going to set it at Zero. I have always used a start up tube on my falcon and my discovery. I have 36 flights on the Falcon now.
See you at the field George
