Unfortunately I landed on a motor and almost severed the motor off the boom. It stripped 1 bolt out and severely bent the motor mount which made the motor beyond repair.... also bent the boom..... so new boom installed about 10mins ago and I will pinch a motor off avril for the time being as she is parked up waiting for the new 25amp turnigy plush escs to be installed.... (they are here but not ready yet) so this will be back flying on the weekend and as you can see from the snippet it flips over on its own axis with the new settings (PRY rates 0.7 from 0.05.... yes 14 times the value..... and RCrate is 1.35)......... so watch this space......... only hope the camera doesnt fall off.........
Ouch ... ouch and ouch. Now I remember why I chose to use the cheap CD ROM motors .... I read an article in my early days of quad work .... the 3mm CD ROM motor shaft may bend and break but are cheap to replace ... will not win a beauty contest though. Where is Gaz Hog ???
I want to say a few words about MPNG 3.0.1 R3. Yes, it definitely works great with our red board! Many thanks to ASPEN hog for help in initial setup. So here is. This is my first experience with MPNG. This is much harder than Multiwii, but not because it is not clear, but because you need to study a lot of material. 100500% that MPNG is not for newbies. Multiwii setup takes just a few minutes editing sketch. MPNG setup takes zero minutes with edititng sketch but many hours in GUI, but you can get a much better result. But it takes a lot of time. For example, you can adjust ROLL/PITCH PIDs in flight with your RX and then save best result as default. You can even save trims to default in eeprom. And a lot more different things. At this moment i have some issues with yaw PIDs and there is a lot of work with precize setup, OSD, current measurement, RTL and flight modes, but QC is up in the air now and stab mode much better than horizon in MWI :) So my conclusion is that 3.0.1 is very very advanced and allows many thing to do besides thing we used to do. I think its great firmware if you want to make T-800 of your Pro board :)
Moochasas, You recommended the NTM 35 motors for my hexe . I can't find them with short shadt. I think they look silly with the shaft hanging down, shell I cut them off or can I find NTM Prop Drive Series 35-30 1100kv / 380w with a short shaft. and if I use these motors with a 5000 mh battery can you tell me the flight time? I know this is not the right place to ask this but please help. I might come to Australia to thank you in person:)
Musa, You can cut the shaft off the motor if you wish, I kept it on because I had to add another mounting plate to the lower section of the frame forming a boxed section to reinforce the base as these motors would over flex the single plate. I was even thinking of mounting them directly onto the aluminium tube but that would mean I would have only had 2 connection bolts holding the motor not 4. (I have mentioned this in my vids and you can see it in the on board vids. so with the lower plate the longer shaft isnt really seen, if you are going to cut off the shaft mark it and disassemble the motor so you dont introduce heat into the bearing. Or you could remove the shaft altogether then cut it....... as these motors do have replacement shafts available. As for the battery I have only used a 4000mAh / 3 cell battery and a 2200 4 cell......... flying mild I get approx 8-10 from the 4k and 6 mins from the 2200.......... flying wild I get approx 7-8 from the 4k and 5 mins from the 2200....... If your going to come fly with me in oz remember to not only bring a quad or 2 but change your mag dec......... wouldnt want to see a "RTH flyaway" And the props make a huge difference as well......... I get better time out of the carbon fiber composite (CFC) props as compared to the SF for obvious reasons of no flex loss....... my reco......keep the shafts long and put another set of props on the lower side as you can never have to moochasas power..........
I like the idea of another set of props on the bottom, I am not warred about these motors braking the mounts, the HAL frame is built like a Sherman tank, heavy and strong. I am warred about the flight time, I was hoping for at least 10 min, with 6 of these motors and a 5k 3cell batt I will be lucky if I get close. I think bolting the motors directly onto the aluminum tube is not that hard by using a supported u bracket. It was always my wish to go to Australia, I have lots of relatives there. So one day you never know. Thanks I appreciate the info.
Musa your welcome. I am happy to try and help people as it can be daunting trying to get the right gear together and make it all work, that is why I make the vids I do so hopefully others can get something out of my experiences and mistakes...... If you get a 4 cell battery (or a few of them) the revs are increased by about 25% so you can lower your revs and not burn out the battery as fast.... idling with a big battery still means you get good speed and control and no doubt you will get 10 plus minutes out of your machine depending the overall weight. I try and keep my quads as light as possible even eliminating landing gear as it flys...... not meant to sit on the ground.....so again with a lot of this info its different for everyone as all machines vary so what I get does not necessarily equate to your machine but all info is useful........ happy flying, go make a noise and vidit so others can look and learn,,,,,, and if your ever over here I would be happy to come fly with you........ cheers
Hitting the ground....... its an up in the air thing.......... sure your not thinking its a robot thang.......... I would love to see the X525 with the 4 cell with 8 props......... thinking thinking thinking..........
The octo ... has to land at some point ... when it goes down at an angle (sticky thumb ... turned on the wrong switch ...) the rrrrrrrppppppp sound is not very comforting. Would be interested to seeing how eight props works on a bigger 525 ... I would suspect a higher lift even with the same motor.
Great unit, with all the features you need for your MC. And the price is awsome, so normally, you cannot make a mistke on buying this unit.If you buy this features in europe, you will pay 3 times as much or more. For the HK price, you get at least the gps module ( sometimes ) but not incluiding the board, wich has a big and powerfull processor also. So another time, where HK makes our hobby affordable. This is what the MC-Flyers need to upgrade their machines.

Received the board today from HobbyKing .
After reading about all the broken Micro USB connectors on other FC like the Crius AIOP , I had a good look at the USB connector BEFORE connecting anything.
The micro USB connector is soldered to the board at the rear corners and also has 2 tabs half way down the sides.
Close inspection reveals that it does NOT have a lot of solder to hold it in place and YES it is likely to break off without some extra solder.
The side tabs do not appear to have been well soldered, my guess, surface mount automated soldering has not applied sufficient heat to get the solder flowing well around the tabs which are part of the larger metal connector shell, using a fine tipped soldering iron, care is required specially on the side near the pin headers, re soldered the metal tabs and also the rear corners of the connector, I don't think it will come off now.
Do keep in mind that is a very small connector and the cable can be used to apply sufficient leverage to rip it clean off the board, no amount of extra solder will prevent that, so be real careful not to apply sideways forces to the cable when plugged into the board.
The quality of the board, the soldering of all the other components, I can't fault it, all looks excellent.
Lots of information now in the files tab for the product at HobbyKing.
I connected the GPS to Serial 2, and the flashing LED
