Simon replied to Jean-Philippe's discussion how do I select the optimized wire gauge to connect motors for my Octa V copter ?
"38 inches from motor to main platform - that's one big machine !
As far as your choice of wiring goes I suggest that you read through the attached file. You'll find lots of similar advice around the web - and on this forum.
With regard to the gauge…"

Simon replied to Randy's discussion ArduCopter-3.0.1 released!
"@ MHA
Re. TBS Discovery geometry - take a look at the Discovery manual. The angles you want (55 deg and 125 deg) are the angles between the centre line and the motor axis to CoT point.
Max Levine did an earlier post re the set-up.
Hope this helps.…"

"Richard, I do like that degrees symbol used by OpenTX, very neat. However the minutes section - 97.8676 - is clearly not correctly displayed. I should have mentioned earlier that the FrSky protocol expects data in the form dddmm.mmmm. I  went a…"

"@ LTMNO
No, of course the numbers don't 'match' - they're not in the same units are they.
Take another look at my post.
MAVLINK sends data in degrees.decimal degrees
The latest FrSky_Mavlink program will transmit the data as -…"

"@ mohd fitri - so how did you manage it ?  I have tried to rescue the 328 following the jDrones advice but no luck whatsoever.
jDrones promised to 'get back to me' last week but (guess what) I'm still waiting - no change there then. Thanks Jani."

Simon replied to Alexander Casassovici's discussion Stylish quadcopter frame design
"@ Jim Powell – what does your printed part weigh ? Assuming that it has quite a thin section,  I’d be interested to hear whether you think that it is going to have sufficient strength to be really useful .  The Dimension 1200es 3D printer I have…"

Simon commented on LTMNO's blog post 6 Position Mode Selection for APM with LED Feedback
"@LTMNO – this could be a long post !
Yes, the Tx is MODE 2. Because of that I wanted the mode switch to be RH accessible. I prefer to keep the throttle under control at all times.
No, it’s not the standard P2 POT, it is a 6-position switch with a…"

Simon commented on LTMNO's blog post 6 Position Mode Selection for APM with LED Feedback
"The problem with simple LED feedback is that you still have to take your eyes off the quad/plane to choose a mode. Also, what happens if you decide to use a different selection of modes - switch re-labelling ?
Here's my solution.
The model and…"

Simon replied to steve's discussion Can I use this magnetometer?
"Yes !
I've tested this with APM 1.4 + oilpan and it seems to work without problem. I see no reason why it wouldn't be OK with APM 2 or 2.5"
