i am still learning rollers, but for me it starts with an early rudder input in the opposite direction of the roll to get the plane turning opposite of the roll direction. I also seem to have to go a little light on the elevator when inverted.

It's always aileron, then opposite rudder as the plane goes towards knife-edge, with occasional down elevator when it goes inverted. Depending on COG and forward speed, I don't need elevator.

to go straight i use more rudder because that's when the plane has less lift,i still use elev. but less impute.You can get away with just rudder but it looks cleaner with both.now for the turns that's when i start using more elev. and change the speed of the rudder(depending on the roll direction you have to slow down or speed up how fast you use impute).ether way you want to practice it i recommend you use rudder to keep the roll looking as clean as possible,might take a little longer to get the timing down but its definitely worth it at the end.

after my original 40 juka got into a fight with a chain link fence (may she rest in peace), I built the 40" backup. Using all DW components (motor, esc) and HS-65MGs.

This is my first attempt at really thinking about a paint scheme and i still didn't get it completely right. I'm still learning though and it will do.. Next time i won't have that white space behind the canopy.

This is my 3rd 40" DW. I have a 48" yak 54 too, but there's something special about the 40"s. I can't quite say what it is though. Maybe its the combination of the perfect size to quickly throw in the car and run to the park for a lunch time flight.

Looks good! I added a bunch of weight to mine with my paint job. I can't take credit for the idea of painting a "reflection" on the canopy. I got that idea from someone else. But I just say it was my idea to most people!

Hi again i was practicing rollers with the juka jr in the front yard and I am getting better, but in the middle of the flight the plane was completely unresponsive and the throttle stayed at half throttle which I was doing at the time when it lost control. All the servos were not moving and the plane went half throttle into the pavement! I'm using a very reliable spektrum ar6210 dsmx receiver and the dwfoamies motor combo with HK hxt500 servos. Freshly charged battery. Plane is pretty much totaled.

Does anybody have any idea what happened?

Sorry to hear about your crash. Are you SURE the throttle was "stuck" at half when it crashed? Also, when you got to the wreckage, did you have control again or was all control still lost with the throttle stuck at half?

First, sorry about your crash.

If you're flying and suddenly you lose all control, it seems like an ESC or power issue. A similar experience i've had to this is when i was causing an ESC to reboot (ZTW esc) in flight because I was pulling too many amps. During the reboot, i was completely without control and crashed.

If it was a power issue (due to faulty esc or faulty power connection) wouldn't the motor shut off? He said that his motor was stuck at half throttle. That's why I was wondering if he was SURE the motor was "powered" at half throttle. If it was, then I'm thinking it had to be something other than power related. Thoughts?
