What version of GCS and Firmware are you using?

[Kyle D.]

GCS 1.0.0 Alpha
f85ae84e 20110819

Is that what you're asking for?

[K Wells]

Do the motors "spool up" full range when controlled by the transmitter

[Kyle D.]

Yeah the motor runs the full range, but everything above half stick is just full throttle.

Gents can you keep this topic for fixed wing specific information please? I don't want off topic conversations in here making it difficult for new users to find the information they need.

Dawg, is this not a fixed wing issue..he either has a faulty setup in his motor config or a radio issue...Why is this not on topic?

[Kyle D.]

Yeah this is for my FPV ritewing Zephyr. Once i get this issue straightened out i can finally maiden it. I just cant figure it out though. Its reading my full throttle stick range as if its from 50%-100% instead of 0%-100%

There was no mention of any fixed wing issue, it was a throttle issue or configuration issue from what I could see in the thread. I stand corrected now I can see a mention of Fixed Wing.

Check the ManualControlCommand information in UAVObjectBrowser, it should be -1 at no throttle and close to 1 on full throttle (I think). Can you confirm I am correct on this KW?

Have you calibrated your ESC?

I assume you have not done any trimming or anything else in your transmitter before setting up the airframe? If not wipe all settings and do everything you can in the GCS. You might find you need to reverse the Elevator in your transmitter once everything else is setup but this only happens if you get the servos mixed around.

[Kyle D.]

Well that seems to be the problem cause when my throttle stick is at zero it shows 0 instead of -1. This explains all the symptoms, but how do i change it?

I am not 100% on the -1 to 1 ManualControlCommand.

It seems your throttle is stuck at mid point, do the transmitter calibration again and see if that changes things. Don't rush that part, I always take my time to be 100% certain I have done everything properly.

Would anyone be able to tell me why my throttle stick shows to be at 50% in the GUI when my stick is really at 0 on my transmitter?

Thanks,
Kyle D.

During calibration, when it says to centre the sticks, set your throttle to about 5% from zero, .

In normal operation, with the throttle stick down, the picture on the gcs will show it at the bottom, move it to 5% and the gcs display will jump to 50% - this is normall

I stand corrected about the need for the PID loop to be changed at different airspeeds.

hi,
when the plane wobbles in thair you need to verify the rigging angle of incidence.
http://en.wikipedia....le_of_incidence
it could also be a wrong cog - as it is in most cases.

when the cog and the angle is correct it flies ;-)
no reason to have a variable pid curve.
on a copter i see a need to do so ;-)


to be safe the magnitude of the accelerometer should be monitored.
that could lead to soften the pid settings - maybe - have not yet thought about a possible strategie.

[Reddog]

So my EagleTree GPS came in and then a day with no wind at all occured, time to test speed. The GPS speed (ground speed) and the airspeed are the same as there is no wind.

At cruise the airframe moves at about 30km per hour, at full throttle the airframe moves about 75-80km per hour.

This means at cruise I can go 9.5KM and at full thottle I can go 12.5KM. These figures are only good for a straight line.

It is interesting to note that I can go further at full throttle than at cruise. This probably means I need to use a higher speed to get a better Watts per KM or change my configuration. I am running a 7 inch prop at the moment and because I hand launch I don't want to go any larger. I think I will stick with the 7 inch prop and be sure my fingers will stay attached.

Be nice, I just wasn't sure who could help me thats all.
By the looks of it Reddog is the man to ask so now I will only post here

not trying to me nasty just trying to show how doing what you did will turn people off trying to help you

as for your problem i only use a 9x so i have no experience with your gear

I got this question via PM and wanted to answer it here for everyone.

***********************************************************************************************************************
I was searching through the post and found that you might be able to help me, I am setting up a delta configeration for a fpv plane but am trying to work out how???? do you leave the Tx in normal plane mode and let the cc board do the mixing to elevons? and what color wires did you plug into the Rx and where (what channels)can you post your settings?
***********************************************************************************************************************

The below answers should work for Revo as well.

Setting up a delta for CC is the same as setting up a delta with your transmitter except you do all mixing in the GCS NOT the transmitter. You setup your transmitter as a blank airframe with no mixing or any other settings first. It is extremely rare to require any settings changes on your transmitter for simple flying around, so do not change anything on your transmitter until you have CC setup properly. Doing it this way might be confusing, but think about the options in the GCS and how they transfer over to the transmitter. For example the Output screen has a start, end and middle Output PWM value. This translates into end point adjustment and trimming for a transmitter.

You setup your CC as a Fixed Wing with Elevons, leave the mixing as it is.

I pretty much always use receivers that output a PPM stream these days, but setting up PWM with CC is fine. You just plug in channel one from your receiver into channel one on CC. I am not going to go to far into this as I have answered this question before and its also answered in the wiki. Not trying to be a pain but after you have spent the good part of a couple of hours documenting something its nice to see people using it instead of reiterating the same information.

Thanks reddog, can you tell me where to find the other post you refered to. takes a long to look through it all, and with kids running around time is limited
thanks again

I cannot be bothered looking around for the posts and wiki articles.

Jet if you don't do some research yourself it will end in tears, you really should try to understand some of the basics. Its not difficult, the Devs have thought through everything very well and everything is very logical. The wiki contains oodles of well written information and has step by step guides for everything, you should start there. This is a good page to start on - http://wiki.openpilo...Hardware Manual

The channel assignment is setup in Input and Output in the GCS. Plug input channel one from the CC (the one with red and black attached to it) into channel one on your receiver, continue to do this until you run out of wires on the CC or plug ports on the receiver. You are only going to use three channels but its better to have those wires tidy than flapping about, DON'T chop the unused ones off.
