Use a receiver with enough channels so u can have separate channel for each flap and in that way you can match up the flaps

[StevenR]

Maiden the cougar today, had 3 flights on a 5000mah and 1 on a 4000mah with timer set @ 4min just to be on the safe side, should be able to set to 4:30, all throws and balance were set to book settings. Take off flight and landing were very nice and smooth and gyro work good, after my first flight I thought the elevator and ailerons had just a tad bit too much throw so I back the servo travel down 10% flew much more scale like!

Now my only issue is that when I go to fly I turn on my transmitter and plug the flight battery in and the Esc is not connecting correctly, everything will connect all servos and control surfaces work but I have no throttle, I have to unplug and plug back in 5 times on my last flight then the esc finally kicked in got the six beeps.
and flew great! Guys at the field suggestion was to contact Motion RC!

Did you calibrate your ESC?

maiden and second flight today, gps on second flight was 130mph from very shallow dive, couldn't use flaps as one of the hold clips on the servo arm of a flap was missing for some reason so we taped it up and didnt use them

So how do work around the wing connection board and the ribbon connection wire? If I could just do the flap wire that would be good. Haven't figured out how to do that.

Yes I did a esc calibration initially but I did have to swap two wires to get the fan to run the correct direction, so I did calibrate again. Still wasn’t working so I did move the throttle trim all the way down and calibrate again! I think it’s working but I’ll check again tomorrow!

[Shemp]

Painted the drop tanks.

What yellow paint did you use? I'm looking for one to match the rest of the plane. anyone know what yellow is on the plane?

Ok need some advice! I did the calibration yesterday, today brought the plane to fly plugged first battery in and nothing! Unplug twice, plugged back in and I got my six beeps, proceeded to fly, about 2 min in the motor started to cut out (scary) managed too land taxi back to me and while holding the I ran up the throttle! Yep! It was cutting out on the ground too! Got on the bench put a new battery in plugged in and no problem! Flew two more flights,

I’m using a yellow 10ch receiver which I purchased from Motion RC ! Could that be causing my problem? Or is it the esc?

Cold solder joint in one of the bullet connectors?

Cold solder joint in one of the bullet connectors?

That sounds logical, I put in a ticket to Motion RC I’ll see what they say, hopefully they’ll just send me a new esc!

[Evan D]

Could be on the motor side too. I just got a brand new one from BH with a cold solder joint on the motor. Remove the heat shrink. Reflowed the solder and put on new heat shrink, done.

How did you determine where the problem was?

[Evan D]

If I touched the connector I could get it to stutter…

I had a can of spray paint that is pretty close. Not exact.

Rust Oleum Painters Touch the color is Golden Sunset

Maiden the Cougar today. 3 great flights. Last flight I flew with the drop tanks and there was absolutely no difference in the flying. This Jet is fantastic. A pleasure to land.
Thank You Motion RC for a fantastic new Jet.

So after about a half hour on the phone with Motion RC tech support we found the problem to be from the new yellow receiver for some reason was causing the esc to not arm sometimes, swapped it out with a spektrum 6ch receiver to test and it worked fine, plugged and unplugged about 20 times and never had an issue.

[Ron1950]

Glad you got it fixed. Electronic issues always drive me crazy.

[Ron1950]

After buying the arf+ version and buying the new esc and fan i out smarted myself as the reason i ordered the arf was i didnt want the gyro. Well the arf came with and gyro anyway and the fan and esc made the total at about 540. Ill buy the pnp next time. Love this plane.
