I have another question ( Sorry for so many) I have a Dx6I 7 channel TX and with my p51 having flaps my DX only has a switch for full flaps down or full up, would it be worth 350$ to spend the money at get a TX that has a knob that I can adjust so I can set flaps at around 5 degrees for shorter takeoff distances or should I fly it first with my 6I and go from there? On most landings with a bird like that I would assume you would want the flaps fully down position so the only thing I would not be able to do is adjust them in increments. Is it that big of a deal not having the knob but just having a TX that has flaps fully down or up? Thank you all again.

You should be able to mix flaps with throttle on that TX, so when you turn the flaps switch on you will get a certain % of flaps down depending on your throttle %.

Not sure if this will help with the P51 though, as I have no experience with warbirds (or flaps yet for that matter!).

I looked at the DX6i and the on/off flaps button was one reason I went for the DX7 instead, which has a 3 position switch and a trim button for flaps.

My Futaba 6 channel 2.4 has the same deal. Flaps up or flaps down. When I flew the RV 4 for the first time I put the flaps down and I knew it was going to ballon up but I didn't think it would be so significant. I might have to try to mix the flaps with the throttle and see how it does if this is possible. Any other suggestions would be greatly appreciated.
Thanks

You can set the TX so when you flip the switch it does NOT drop the flaps all the way... adjust the servo travel amount to do this.

Normally you'll find that you'll only need about 30% flaps for them to be effective.

I tried that last night. When you go to set the expo it won't go to the flap channel which is 6. Maybe I'm overlooking something.

No, it's not EXPO you deal with...

Rather the amount of end to end travel of the servos...

Normally it is set to 100%/100% in each direction.

Dial these numbers down to say 30%/30% ( up/down ).

Oh ok I see what you mean, I will do that because I know in a real cessna 172 and 182 and Piper cherokee which I learned too fly on you only need 30 degrees of flaps and usually not that much, but I will set them at 30 just incase I eventually come in high and fast when I maiden her. Chopper your right, it will balloon up ALOT when you hit the flaps from 0 too full even in real aircraft the amount if lift you get is a major difference, so are you going to set yours at 30 too?

Mine are pretty much set at 30. I don't think it's so much the travel is as much as it is the rate/speed that they move. This is my first plane with flaps so I really don't know what I'm doing.

Eh, No, it's not the rate or "speed" which they move.

Rather you want to adjust the "endpoints"... or "travel".

That is how FAR the servo turns when you activate the switch. ( or for other channels how far the servo turns when you move the sticks ).

This allows you to have more precise control over the flaps, so flipping the switch can result in a 30% drop in the flaps as opposed to all the way down.

Impressive. Can you tell me where to find one of these? All I can find is the 6 channel version. Maybe I'm missing something.

Im sorry bruce, that was my typo, it is a 6 channel Duhhh LOL my mistake LMAO.....So until I get the DX7 I guess a smoke system is out of the question, but someone I know is selling there bran new DX7 for 200$ that has a MINOR scratch on the monitor which is no big deal since I will be saving over 150$ from buying one new. I was wondering if someone was going to catch that LOL. Chopper, this is my first with flaps too so I am in the same boat as you, I am clueless on setting them until I posted this because I did not want them to drop all the way and have it balloon up and screw up my final approach when I maiden her.

I elected to land without the flaps. I extended the flaps at altitude. Didn't feel confortable putting them down for landing and then have to do a go around. I think I'll practice that manuver in the air first.

Chopper how did it land with no degrees of flaps extended? Did it come in fast or did you manage it well with throttle and pitch? Why did you feel uncomfortable with using flaps, just want to know so when I maiden my Mustang I know what too expect from those who have flown one already, or a plane with flaps in general? Now will 30 Degrees cause the plane to balloon up alot or does it take more, I did notice on the sim with the corsair when they where extended it ballooned up so much I took the flaps off, but that had split flaps which could be why. BTW Does anyone know the max degree the TF flaps extend? Is it 90 degrees or 50? Also I have been wondering, with my golden knight 100 in her what kind of speeds will this bird reach and will it fly nicely and 50% throttle without stalling? Thanks alot.....

Jacked69
It came in a little fast but not uncontrollable. Mine pitched up alot when I lowered the flaps. I might have to reduce the max degree of extension. The main reaseon I did not want to land with flaps is that if I needed to go around I 'm not use to having to bring the flaps up along with just doing the go around proceedure. Full flaps on a takeoff or a go around will not have pleasent results. I'm going to pratice with a little ground beneath me with the go around. On an rc model I don't think you would takeoff with any more than about 15 degrees of flaps. That's how it is on the real birds anyway.
