Hi All.After a long time away from using APM I was recently lured back.Unfortunately it's not been "plain sailing". I hope one of you can help me with an issue I have been experiencing for the last 5…Continue

Lyn Rees commented on Howie Liu's blog post PCB Rapid Prototype
"Hi Howie. A very factual sum up. However as many of us consider this a hobby, even if taken very seriously, I think cost will always be the deciding factor. I completely agree that prototyping is the preferred method before committing to full route…"

Lyn Rees commented on Kirill's blog post SmartAP Power Distribution Board
"Agree with Hein, great product, Is there an option to specify which Allegro ACS 75x is fitted? 50A. 100A, 150A etc. I also assume the fitted ACS is of the unidirectional type (makes a difference to accuracy). The one I designed and am waiting on…"

"I still have a pair of APM 1's carefully preserved wrapped in tissue sealed in a box:-). I am however very envious of your access to a 5 axis CNC. My day job gives me access to two 4 axis Bridgeport (Hardinge) mill's only, and a couple…"

"Hi Monroe & Mark. Yes! Thats the one! I remember following it religiously as they seemed very confident in achieving sucess, So glad you found it Mark as it inspired a lot of what I do today. Lyn"

Lyn Rees replied to Tim Squires's discussion Plane drop from balloon
"Hi Tim. I remember many years ago some guy's in Canada spent a long time experimenting with this with various rates of success. They had a really good web site tracking their progress. I have tried to find reference in my PC archives but as yet…"

Lyn Rees replied to Alexis's discussion Strongest Motors on the market
"Hi again Alexis. I think you made a good choice. Although just yesterday I came across the T-motor F80 KV1900. Puts out a "claimed" 2.050kg thrust (6S) with just a 5" x 4.5" prop. Just the ticket for a quad racer I think:-). Lyn."

Lyn Rees replied to Alexis's discussion Strongest Motors on the market
"I cannot vouch for Andre's experience of T motors. Maybe I have just been lucky. I tested a sample of both type I mentioned, 3520 & 3508 and the results were in the ballpark of the data sheets, even the temperature was at an acceptable…"

Lyn Rees replied to Alexis's discussion Strongest Motors on the market
"Ahh. I understand better now. I run 8 3520/400 with 1555 or 1755 props on a 6S pack so a different scenario. I also run 3508/380 motors and as I said I have not had an issue with any of these. But again these will be to big as these are again on 6S…"

Lyn Rees replied to Alexis's discussion Strongest Motors on the market
"Hi Alexis. If you want the best you cannot go wrong with either of the two manufacturers you mention! I have used T-Motor ESC's and motors predominately over the last few years and in hundreds of flights I have not had a failure,as far as I can…"

"Am I being churlish to mention that strike capability has no place here on DIY drones? I see that you have included that at the end of the Video!"

Lyn Rees replied to Curt Zerr's discussion Which controller to buy for an autonomous drone?
"Lots of choice here. I have found I more and more use my Taranis rather than say my Futaba. It also has the advantage of having the Tx inbuilt, the 9xr does not. If you decide after the project its not for you I guess it would be easier to sell the…"

Lyn Rees replied to Tom's discussion APM 2.5 Roll Offset - won't allow level flight
"Hi Tom. Your situation sounds very similar to mine. I can only say I did, today, apparently cure mine. As in my post I was using a Taranis Tx with the throttle on channel 1. This seemed to work at first glance, but in practice, as I said it was…"

"Hi Lyn, I'm can't offer a solution, but it seems we're having the same problem... http://diydrones.com/forum/topics/apm-2-5-roll-offset-won-t-allow-level-flight Does my description match what you're seeing? Hopefully one of us…"

Will Fellmeth replied to Lyn Rees's discussion Hexcopter rolling with neutral input
"Lyn, I'd re-do a radio and accel calibration, if that doesn't work find out where the CG is on your craft. If you find that it is not in the general center of the craft try re positioning items on the craft to shift it to the center. If…"
