I have a Futaba T7C (7 Channel) , Futaba T9CAP with spectrum module and a Spectrum DX5e transmitters. First I used my Futaba T7C with R617FS receiver and after the second crash with the Mig-35 I installed a spectrum receiver with my Futaba T9CAP and crashed again (same problem) and destroyed it. After destroying the MIG-35 I heavily tested all servos (with a servo tester) and found the right aileron servo failed. While manually tested the failed servo (with a servo tester) I noticed that the servo was short circuiting causing the tester to turn on and off, that maybe caused the receiver to jam (become unresponsive) in the Mig-35. I use an external BEC's 5 -7amp ratings in all my parkjets.
The 2X4 I am referring to is when the elevons are mixed with ailerons (by V-Tail mixer) and ailerons work normally as ailerons.
The 4X4 is aileron and elevons mixed (linked together) in the transmitter or by V-Tail mixer.
What are your favorite setup for parkjets?
My Mig-35 (that crashed) had a standard setup with two aileron servos and, one elevon servo and one Rudder servo. A great flying parkjet.
I have a DX5e and noticed the throws are very small and slow compared to my Turnigy 9xr.
I think it is designed for the rookie pilot with such tame settings.
Try to avoid mixing transmitters with one model. I have lost a few planes when I used the DX5e on a model set up with the TGY 9xR because the throws were too small and slow.
