HI Dave,
I have a 1/5 PNP BVM F-16 and had jittery servos with DS-24 and CB400 on 7.4v when I first had it 2 years ago. I changed the Spark servos to MKS and still had the jitters. The problem turned out to be the servo leads in the jet. I replaced them with Powerbox Maxi wire and the jitters stopped. Best flying F-16 I have had. You will love it.

That's good wiring, I've re-done a couple retrofits with PB wire

Thanks very much.

Did you just splice your own plugs on? Did the PB ones fit the BVMs servo plugs?

I plan to switch to the PB Maxi wire for my next project (1/4.5 F35) so this will be a good time to try it out.

I made up my own extensions by crimping the servo plug pins on the wires and installed them in the jet.

Did you use the PB plugs?

Yes I used Powerbox plugs. Highly recommended.

I was setting up my CB 400, R3 rx1, rx2, rc switch ...I bound each receiver after setting dual path. worked normally and confirmed each receiver was bound.
I went to DE and adjusted each Rx for the CB/ Ex Bus....but when I went back to that page, DE entering from the menu again, there were Xs instead of check marks for the R3 although a check for the CB. Antennae (4) were zero signal.
I wound up re-binding the 1and 2 receivers (just from the tx menu button) and then all were "checked" in DE.

Does this order matter if it is showing them all "checked" three r3 receivers and the 900 and the CB checked (no X marks ) if that all makes sense? My antennae are now reading appropriate numbers and servos all working properly. I just never tried the re-bind once I had the CB /exbus setup before. It looks fine to me but I am still learning as well.

thanks,
Dave

What’s the question?

ddennison

My Feedback: (15)

The question - Does the order matter if you rebind the receivers after the CB is setup for ExBus and dual path versus the usual receiver binding and then setting Ex BUs after in DE?

Might be difficult to explain but the initial setup - binding the receivers and then adding to CB in ExBus, seemed ok but then when I looked at the DE the R3s were not "checked", they were Xs and the antennae had no signal. At the point I just went back and rebound the primary and secondary (already know) receivers and then they were all active with Check marks. NO worries if ti doesn't make enough sense. I will be testing it extensively in the next few weeks anyway.


on another note - playing around with combined flight controls for the F35 setup so it will have many options in flight modes , especially at slower airspeeds where the horizontal stabs will have much more control of roll and pitch. I am happy with the inboard rudder mix at T.O rotation as well.

If I start a new setup...here’s the way I do it....

‘’I power the first receiver with a bind plug and in wireless setup #1.....I keep it power and power the number 2 then the 900.....none of these are connected to the CB.

Remove the batteries connect everything into the proper place of the CB then power it. Then go to the devices one receiver at the time disable failsafe, set the proper port to exbus....do all of them...then the CB should be under the first receiver...then you can setup the rest of the stuff in each RX and CB..

Not sure if this what you wanted......but I always do it this way....and never encounter much trouble...the odd time my RX switch doesn’t want to connect....I est my Jetibox and in 5 second it’s....

My Feedback: (15)

Thanks. I did it the same way. IT just was different after I exited the setup after adding CB to ExBus. The display looks different now as it shows

I don’t think your receiver were power then.....they should have showed, but it works now it’s all good..

Hi guys.

One more question; I set up my display for telemetry to include the rx voltage. For my table top testing I am using a 6.6V A123. The display on both batteries (no servo load, 6 servos plugged into CB400) was 5.02/5.03V. Manual test at rest was 6.5-6.6 on each battery and 6.2 or so with 0.5 amp load.

So why might the voltage be that far off?

Thanks for any advice,

Dave

Dansy

My Feedback: (53)

Not sure why you got the discrepancy, I have played with and own a few CB400 and none.show this.......but what did you set the bec for ? I would guess about 5.5v

Yep, up your Voltage out via DE

SO with the CB 400, I will have 6 (minimum) HV MKS servos powering the CB400 with 7.4 LiPo. I might use the BEC to power something (rx/servo) given the size of the plane.

2 questions, in a few parts,lol:

1) DO I need to set the the output voltage (presume this is the same to servos as to the CB? What about pins 1-4/20-24?) in the CB to 7.4V? When there is a load the batteries dip below that of course so can it maintain 7.4?

2) Does it matter if I split the HV servos load on the two sides (5-12) and (13-20) or can they be all for example in adjacent slots 5-10. Any difference on the bus or regulators ?

Thanks
DD

The way the CB’s work is they only used one battery at the time....and flip flop as required between the 2...they might not be exactly equal let say right after landing.....I normally used the bec to power retract and lights.....

the biggest advantage with the 400 is to use 3s or 4s batteries...set the voltage to 7.4 (FIRST) that way your ensuring that you will be at or closed to 7.4 (could set it to 7.6v for surges....)

The only time I have used a 400 is when I don’t have enough port on a 200/220...

Thanks Daniel.

Here is what I will have:
7 HV MKS servos (2v,2h,2 ail, steer) and then Electron Gear (3)and doors (6) sequencer and brakes. Lights hopefully too....So I guess I could tap off the BEC for the Electron power if I go with a bigger battery. That might be a better idea to sure the servos are receiving full voltage all the time.

My question I guess though is - what setting to use if I use a 7.4. supply for the flight servos? I may just add a separate battery for the Electron stuff.

Im guessing if it was set at 7.4 and the voltage started to drop (say flaps down) that it would keep sending power to the servos as long as it was not overloaded?

Thanks
Dave

Dansy

My Feedback: (53)

Well the electron take 2s so 7.4v unless you have the er30 or the er50NG (pro) which both OS these can take 3s.....So not know which retract you have I would venture to say set it to 7.4 and don’t worry about it.....if you can feel a couple .2 volts different in the servo response...you would become my new hero

So flier might but I sure can’t

Hey folks, I am having issues getting this set-up. I have a Esprit Elite 80SB8S/5A Brushless ESC with telemetry that I want to use with a EX R12 REX Assist 2.4 receiver. I have the R12 all set up and working well with servos. I can plug in the ESC’s throttle wire (black lead) into the receiver and the whole thing works great. But what about telemetry?

I know there is another lead coming out of the ESC that I assume is for telemetry (red lead)? Where do I plug that into on the R12? And how do I enable telemetry from the ESC? I assume that I can see RPMs, battery voltage (am running 6S), watts or amps, etc. Can I set a cutoff voltage and what happens to alert me to that cutoff? Any other cool things it can do? There were zero instructions with the ESC.

Thanks.

The only ESC that has telemetry for the transmitter is the Jeti Mezon Pro models, at least in the graphics and info you are used to seeing on the jet telemetry. I broke down and ordered one after watching Harry's video on the Mezon Pro 80. You can use the transmitter as the Jetibox to program the esc, but the telemetry is limited on the other Jeti ESCs. Hopefully I am wrong but that is what i gathered off two nights of videos...

That lead should plug into the RX, EXT port, If it is an EX Device you set all the alarms in your Alarm menu, otherwise you will need a Jeti Box hand held unit or you can do it in the TX jeti Box (Not as Easy Though)
The most important alarm is the Capacity alarm, you set the alarm to indicate "Used" capacity so a 6000 mah hour battery you would want the alarm to go off at 4500 mah.

OK, I have the red lead plugged into the EXT port. Is the REX12 Assist receiver an EX device? When I go into the Alarm menu, I cannot see any mention of setting alarms for 6S battery voltage, only receiver voltage. And no way to set up other ESC type of things. Is their a good on line TX Jeti Box tutorial? Thanks.
