trex hde flight issues
ok, can you suggest some tips here??? I am experiencing two problems with my trex.

1. tail issues. gy401 with 9650 (or whatever the futaba digital gold standard for the trex is). the tail is holding great in hover and slow manuvers but as soon as i flip it or roll it the tail does not always hold. also, the tail response seems delayed on fast forward flight. Example, moving forward, hit l or r rudder and tail moves slowly then whips around.

2. nose is pitching up in fast forward flight.

any tips?

thanks!!!

my cde was doing something simmilar it was all in the set up

make sure your in ds mode
set delay to 0 using the 9650
set rudder atv to 100 no subtrim
set gyro up in rate mode[blinking light]
power up servo make sure horn is centered with ball link directly in center close to servo

set tail blades at o pitch [center slider]
adj tr rod accordingly may have to slide servo toward or away
make sure travel is equal either direction
set limit on gyro till it just starts to bind
reintialize in hh mode set gain to around 60 and increase till wag and back off a tad
hope that works it seems to have helped me

pitch up in FFF
I have to set the elevator trim for the speed I want in FFF. Then need to change it a little when hovering. A little bother but no biggie.

I thought it was normal to keep some "forward" in during fast forward flight. Am I wrong???Pete, Trex500, Trex600E, Streched 600, DSX9, DX7, Low-volt alarms - check the gallery for my alarms

what is happening to me is that I am coming down to enter a loop and I prepare to pull back. at this point, it pitches up a lot. making it tough to loop properly. A learning curve? Normal trex behavior??

What rpm are you running? You can try running the 401 + 9650 on 6v as I found it keeps a much more consistent piro rate while in forward flight. Also disconnect the tail pushrod from the servo and move it by hand, look out for any stiffness or flex, the pitch slider should move over the tail shaft freely and smoothly. Then make sure your 401 is able to use the full tail pitch range by adjusting 401 travel limit and linkage position on servo arm.

Pitching up in forward flight is normal to an extent, does it pitch up slightly and smoothly or is it abrupt and violent? If the latter, the retreating blade is stalling and you need to increase your rpm.

If it’s a slight pitch-up then you’ll just have to hold some forward cyclic, higher rpm will reduce this tendency, as will a forward CG, but then a forward CG will make it worse when in backwards flight and will mess up your trim when inverted.
