I didn't spent too much time on my radios. I just pluged them in for "airframe clearing"purposes. I will check out the setting further.
Thanks again.


Looking great!

I'm not sure what your wiring set-up is, but this little Turnigy 3 channel controller works great for my trike servoless retract system:

Be advised you need a male to male servo lead to connect this to your receiver.

No sure why the delay
Looking good! I got the same delay while using the E-Flite Y-harness (the small ones with tiny guage wires) and got a boost when switching to more beefier ones. Every once and awhile I still get a delay though

Keep up the great work!

Thanks for advise guys.

Ok some updates. Rear section is finished and installed to the fuse. Nose section is ready to be installed but will keep it off until last min.
I'm still working in the main landing gears.
Flaps are linked up as well.

Next is to hook up the engine pylons and motors along with running the ESC's,
I'm not sure what I was thinking prior to starting this big bird.

I suspect you need to point them a little down. If you think about it - if you hold the plane at its exact CG and apply power, since the engines are below the CG, they would create a torque rotating the nose up.

Doushi, Sergey is right the #2 engine on the DC-10 is angled a tad up and the two wing engines seem to be level with the fuse, I personally try and match what is on the real thing that way your airliner will behave a tad more predictably.

By the way she looks FANTASTIC BRO!

Ah, but then in this case I'm actually wrong and my logic does not work. Because according to my logic you'd need to angle all 3 engined down, not up.

Hi Doush:

Your fuse looks great, very clean work, I wish mine were as precise.

In answer to your question on placement, and angle I think you'll find this short paper useful. The most relevant info will be in the last section.

Hope this helps.
Joe

there's also the logic that says that your thrust angle should match your datum/waterline and that your incidence angle(s), or lack of should also match your thrust/datum lines. of course, good decalage would dictate that the angle of incidence of the wing should not be the same as the horizontal tail so that you will have positive stability.

Minor update
Fuse semi painted. Fuse is 632g. I changed my mind about transporting bird. I modified the the wing box to make it a one piece wing. I will pass my target of 3.5lbs.
