DX 7 Logo 14

[WillJames]

Got my Logo 14 RTF witht he DX-7. :)

Can't wait to test fly!!

[MicroMan]

Nice setup youve got there, cant wait until I get my DX-7.

[WillJames]

Thank you MicroMan!! It is a sweet flying machine! I will let you know how it goes withthe DX-7

[Lorents]

Thanks for the pics and the DX7 setup Will! Good idea using glue to straighten out the small antennas :)

The antennas of the second receiver looks close to the main gear, but you probably have that under control.

[WillJames]

That is hot glue to strengthen them where they exit the RX.

[BobbySmith]

Will you are going to get hooked the DX7 is jsut flat out cool!!!!!! I wish i had another rx as i wanted to set my 14 up now

For what it's worth, the best thing I've ever found to use as a strain relief (I realize that's not exactly what you're going for), is AquaSeal by McNett. It's similar to ShoeGoo, except better bond, and it stays absolutely flexible forever. Once you try it you'll find a million uses for it. Also beats the heck out of heat-shrink if you need the splice to be waterproof.

Thanks for the tip Rick!!

Will you are running the "gear in manual" and not automatic per flight mode correct? I am going to use my gear switch direct on manual for gyro avcs and norm. I have heard some are using aux2 for gyro gain vs gear switch, is there any difference other than switch location?? It is weird using 51% in avcs to see 37% on my 611 amp for HH, and 46% to see 37% in non HH on my 611 amp,,, weird...BTW are your throttle endpoints 120/120 for ends on the CC controller or why are they those values? Are you guys running any expo? I have heard some people saying this radio is fast and yet sensitive and people were running some expo on both ail/ele,,, curious as I have never ran any expo in any setup but....

[WillJames]

I am not running expo so far. Hope to fly today. From looking at he swash, it looks to move very similar to my 14.

I am using the gear channel for Gyro gain. I too like to be able to reset my 611 by flicking the switch 3 times. I tried to use the GYRO program in the DX-7 but went to just using ATV's like I used to withthe 9Z to keep the gear switch making the change on the TX for me. Pretty simple to setup the DX-7.

[WillJames]

Whoops missed the throttle ATV's. I do not have another CC ESC yet, have a couple on order and I use the 120/120 on the Jazz 55 that is currently installed. Once I get the Castle, I'll set the endpoints in fixed endpoint mode then run GOV mode.

[OICU812]

Does it need to be opened up to 120/120 on the Jazz to work properly Will or ...? Curious, I have only ever ran my Jazz escs at 100/100, mind this was on the 9C Super so wondering now if the DX7 is different and if I should be incorporating a rule on my programming as I have several Jazz escs'.

[loopzilla]

Nice rig Will.

I just dropped the DX7 in my 14 to see how well it works with V-Bar. I hope to have some more Rx's arriving next week or so, then I can try it in my old problematic Mini Joker.

I think I'll be happy for a while with this thing.

[Finless]

Hey Will... the Logo looks familiar :)

Not sure Shawn. I started opening up my throttle ATV's when I used the 40-6-18 on the small T-REX's and it worked a lot better for me. Better power for some reason, so I have always just done it. Not sure if it is needed on the 55 or not actually??? Does anyone else know???

[MrMel]

I always program my radio with Jazz so light comes on in the end of each throttle response, on futaba thats usually 82/82

Is that wrong perhaps? Then again, I run governor so I guess it dont matter much, just changes the resolution of the throttle % wise.

[loopzilla]

I just programmed my Jazz with 100 / 100 on the DX7, and I can hear an RPM change (with Idle Ups) between 70%, 90%, and 95%. So, I know the governor is seeing at least a percentage as small as 5% with the DX7. But, as usual, you have to program the Jazz into mode 4 with a linear throttle curve 0-100% and 100/100 ATV's.

One thing I had to learn again this morning, was the stupid Expo is backwards in the DX7 from Futaba or Multiplex. I have known this for years, and program JR radios daily, but just flaked out when programming the DX7 last night.

I just came in from flying the 14 with V-Bar with -50% expo on AIL and ELE in the DX7. Talk about twitchy! Switched it to +30%, and it seems to work a little better...

I've been a die-hard Futaba guy since before expo existed. But it seems to me Futaba got it backward. Where do they get off calling what we use "negative" expo????

[loopzilla]

I actually makes more sense to me to be negative, as you are decreasing the sensitivity.

[spork]

I actually makes more sense to me to be negative, as you are decreasing the sensitivity.

Well you're decreasing the senitivity in the middle, but increasing it at the ends.

Y = x^n

That's our exponential curve, and n is positive when we decrease the sensitivity in the middle and increase it at the ends.

EDIT:

Actually, I think n is always postive. It's either greater than, or less than, 1.0 (n=1.0 would be linear; no exponential throw).

[loopzilla]

Makes sense when you see the formula. Thanks!

OK flew the Logo today with the DX-7.

First off something weird happened. I turned on the TX, then the Heli. The RX's got the red light and the green link light on the back of the TX came on, but the heli would not react at all to any stick movements. Very spooky!

I turned everything off, then turned on teh TX, then the RX and all lights came on and everything worked. I did this 3 more times and every time I had control. WTF happened the first time?

OK now to the flying...

Since I had a 319 in the machine instead of a G3 RX, I can't compare 2048 PCM to the DX, but I can say that the DX is a little faster and more crisp feeling. For example, I have been working lately on rainbows. I did the best rainbows with the logo today I have ever been able to do, I even could throw in some pumps. I am trying to also figure out the best 611 gain. I did some BIG backwards outside loops and the tail would start to drift about 3/4 of the way through. The machine was definitely not bogging, so not sure. I have to run my gain at 29% to keep the wag away in Fast Flight and maybe it is just not quite enough for BIG backwards loops? Might have alse been the wind, it was a little breezy up there.

The machine flys more crisp with the DX compared to the 14MZ/319. I do have a little bit of interraction but I ordered the new servo arms from ReadyHeli to fix this.

Overall I love the crisp feeling of the heli flying, this Logo 14 is a LOT of fun. I can see my flying improving with it, and I still have not flown the sim.

Then only thing I don't like is that the radio feels super cheap in my hands. I do not use a neck strap so the balance feels fine, it just feels cheap. I guess from a 14MZ, it should but it is going to take some getting used to. The other thing I definitely did not like is how I got all the link lights but no response on first try. WTF can cause this, and is it normal? do I have a bad TX or RX? What??

Same thing happened to me, like "microsoft", reboot and your fine.
I guess the allocation of channels went "bad", then better safe then sorry, its not gonna work, you need to re-init.

Just taking a stab in the dark. Perhaps you need to have a second or two of delay between powering the TX and the RX. I can't explain why you got the link lights.

I have to run my gain at 29% to keep the wag away in Fast Flight and maybe it is just not quite enough for BIG backwards loops?

Higher gain should probably help. In order to avoid the wagging, you should make sure there is no slop, no binding (i.e. very smooth controls), and no delay (fast servo).

Probably this is all stuff you've already thought of.

[MrMel]

Will, Whats your TR blades?

29% if good enough if you run 92mm or more on a gy611.
ask Danny (alu-swashplate) :)

However, with stock, you need to get it higher
