with the wings extended or retracted? I understand the rest of what you are saying

I don't recommend trying to put the flaps down with wings folded back... You'll strip the servos.

There's enough sweep with the wings extended for the flaps to act like elevons. Amplified if you linked ailerons to flaps for scale flap system.

where did the edit button go?

[C17loadmaster]

Its not a high wing vs low wing issue.

Its the wing geometry vs the flap geometry in relation to CG. (among other factors)

At speed, the F-14 acts somewhat like a flying wing and the flaps act like elevons. (yes, I have one)

I've seen this with a few swept wing models.

I had a Nitroplanes Falcon 120 that I stuck a 5 inch EDF on. Programming the ailerons for elevon the ailerons had more pitch authority than the elevator. Because of the huge EDF nacelle blocking airflow over the horizontal tailplane, I could completely lose pitch control with the elevator when chopping throttle, but could loop on the ailerons in elevon mode.

Ouch!:(:Crying:

[C17loadmaster]

Yes it was...

[DCORSAIR]

No problem. The low wings are easy to set up flaps and elevator mix. High wings like the F-14 require a ton of up elevator. I actually destroyed my F-14 on my second flight by testing full flaps while flying too fast and too low. I added a 3 second delay to make them more scale and in doing so made them too slow to retract before it exploded into the ground like you wouldn’t believe

:Scared: Wow, I bet that was a mess of foam..........:Crying:

Good to know thank you for the quick response.

No, I have none set. My landing flaps are set up for maximum deflection too. They’re almost 90 degrees down

Does the FW F-86 need any elevator mix with flaps?

Flew the f86 today off a great tar surface. It was first few flights sense i installed the fms 2000 kv in runner wow this plane with the upgrade motor is a beast. Fast. Sounds great. Powerfull vertical etc. hoghly recomend this new fms fan.

[C17loadmaster]

Mine is set up the same way except I don’t have a piece of wood between the battery and ESC. It’s is directly in the intake airflow on one side and flat with the battery tray. I’ve flown this plane more than any other EDF.

[Rcjunkey]

[Rcjunkey]

I do the same thing and it does get warm but I’ve had no issues. I have a 100a ESC and FW Inrunner in mine

I moved the ESC under the wooden tray, it keeps from having the batt. Sit on it and puts the ESC in the he air flow for better cooling.

[C17loadmaster]

went with the fms 2000kv inrunner but to make it tail sit had to move battery back to sit on the 100a esc anyone else do this? is there a problem cooling etc? haven't flown it yet with this set up

I now have the gremlins worked out of the landing gear and got three good flights today. I posted a video over on the "What Did You Fly Today?" thread.

Overall I am pleased with the plane and the way it performs. As others have said, it is not a speed demon, and I actually like that. It looks very scale in the air.

I have been using Admiral 4500 batteries with my timer set for 3:30. I am coming down with the battery just warm, with about 30% left and 3.8v per cell.

Is anyone here using a 5000ma battery? If so, any issues with the bigger battery?

I fly the 4000 and 5000 Admiral...no issues, but i can feel the difference in weight when flying for sure...prefer the 4000.

[rifleman_btx]

Yes! Its the best feeling ever!
