Getting off toy quad, opinion on FC for 120 quad

This might be crude, but it'll give you an idea on how 66mm props would look on the MI110 frame.  I've circled the areas that are conflict concerns.  The spacing between the forward legs on the upper plate is about 16mm, so most AIO blocks won't fit there.  Looking at photos in the banggood comments, yeah it looks like people get creative in fitting things onto the frame.


Damn that's an awesome picture bro, I really appreciate the rough sketch it gives me a much better idea of sizing and fitting an aio. Looks like I'm gonna have to get creative like you said. Thanks for all the help you guys have gotten me all the way up to actually getting the parts and building it! Only thing I have left to order is the props and aio. I'll have to do some research on aio for form factor, the only one I've ever used is the eachine tx02.

I'll start positing some pictures as my build progresses.

(Edit) I picked up a  redcon r720x from banggood. Perfect combo of form factor and features. I keep forgetting that banggood has just about every quad part you need.

I'm not convinced as to the quality of the Redcon receivers, but see how it goes.

If I'm going to use DSMX, then I always use the LemonRX diversity satellites. The long dual antennas are perfect for carbon fibre frames as you can easily position them away from the frame for good reception.

I can easily get well over 500 metres range with the LemonRX satellite - probably even further, but I'm out of airspace at 750 metres.

I really wish that deal existed when I bought my Devo 10. It's an unbelievable price for a really good radio.
As it is, I have both a Devo 7e which I've added extra switches and modules to, plus the Devo 10 with a 3-in-1 module, so I'm pretty much covered. I still really like the Devo 7e as it's such a tiny little radio that it takes no space at all in a back pack together with a couple of smaller quads.

I've attached a scan of the CF plates from the Mi110 frame, minus the motor grommets.  For a full resolution version of the file, see https://dl.dropboxusercontent.com/s/vk7s...ullres.jpg

Ahhh, I read some good reviews on it so I figured I'd pull the trigger. I guess I'll find out how the range does, I'll let you know what I find out. If it fails I'll probably buy a lemonrx.

It'll probably be just fine. Maybe I'm just being cautious...

LemonRX seem to be a pretty good company. They have worked closely with the community and seem receptive to feedback and suggestions. Their prices are great too!

Yeah everywhere I looked I kept seeing lemonrx it seems like everyone is using them, I just got something cheaper since I'll probably destroy this mini quad quickly when I'm getting used to fpv.

Thanks for that, gives me an even better idea for spacing. I think my Aio might just barely fit if I swap the antenna

I've got a couple of redcons (decased) on a couple of micros.  Haven't pushed them out very far yet, but they are definitely OK to 100m or so.  One nice thing about them is they will take 5V without frying (which is the main reason I got them).

I figured you had already committed to the MMW motors when you mentioned 17kv.  A lot of people are committed to motors from MMW, but I couldn't let myself fork out that amount of cash either.  I'll share that so far I'm impressed with the Banggood Racerstar motors.  I figured they were a mid-point between the typical low end motors and the MMW stupid fast ones, at less than half the cost of MMW, and providing longer flight time to boot.  My 3d printed quad with the Racerstars has a surprising amount of zip.  I haven't been able to go to full throttle - I'd lose orientation in LOS and possibly range from my low power VTX in FPV trying to take advantage of it. Unfortunately Banggood specs them at 53500RPM instead of a kv value.  I assume you divide that RPM by the rated voltage of 3.7 and come up with 14.5kv.  

I've built up the 2nd quad with the nano-QX type frame, minus the FPV gear.  I put Spintech Sidewinders from Amazon on that, spec'd at 15.7kv, so another upper-middle range motor at about 2/3 the cost of a MMW set. A key difference here though is the Sidewinders come as a set of six instead of four.  Unfortunately, very little run time with them so far. The weather here has been either wet or too windy for a brushed quad and I can't really open it up indoors.  

With such a short expected lifetime on brushed motors, I figured I'd wear out the more affordable Racerstars and Sidewinders before my skill level would appreciate more expensive motors.

Have you flashed deviation on your Devo 12e yet? I tired to and bricked it, couldn't even flash the new bootloader but I have another on the way and I was just wondering if you knew the process well.

That's good to hear! I should be getting mine this week

I hope you can bring the bricked one back to life.

The instructions for installing DeviationTX are in the user manual here: https://www.deviationtx.com/user-manual/...nual-7e-10

They are comprehensive instructions. The Devo 12e is essentially a Devo 10 with two extra pots, so just follow the instructions for the Devo 10 and it should work fine.

Note that you won't find a build for the 12e under the main downloads section as the 12e wasn't around when the last 5.0 release came out. You need to download one of the nightly builds from here: https://www.deviationtx.com/downloads-ne...tly-builds
or, you can download one of vlad_vy's builds which only add the latest protocols to the official 5.0 release. This is probably the best option and is what I run on my Devos. You can find vlad's thread here: https://www.deviationtx.com/forum/builds...-protocols
Just go to the last post to find the download links.

It's also really important to check you are downloading the correct firmware. A Devo 12 and a Devo 12e are two completely different radios!

No on the Devo 12e. Any idea on what you did wrong? Mine's not expected to arrive until tomorrow, and it may be a while before I get around to doing anything with it. Unseen, thanks for all the reference info.

Well that might be my problem, I tried flashing to bootloader which went through fine but the only bootloader deviation has on their website is for the f12e and 12 and the tx still wouldn't start up, any idea where I can find the 12e bootloader because then I can probably get it back to the land of the living.

Thanks for those links by the way, I'm gonna study them after work to see where I went wrong.

I've never needed to re-flash a bootloader on a Devo radio. It has one installed and normally, you can't damage the bootloader itself.

I'm surprised you managed to damage it to be honest. You'll need an ST-Link programmer to re-flash the bootloader if it really is damaged. I'd suspect that the bootloader for the Devo10 will work just as well seeing as there is very little difference between the Devo10 and the Devo12e.

When I flash Devo radios, I use the DeviationUploader program (primarily because I don't use Windows) and it's simple and reliable. If you have Java installed, the uploader will also work on Windows and may be a safer and more reliable option than the Walkera utility.

I actually have the st-link, I'll try flashing the Devo 10 bootloader after work, not sure how I damaged it but something's extremely messed up on it, like I said I have another one coming but it'd be nice to get it working anyways.

I tried using the deviation tool but my girlfriends laptop wouldn't recognize the radio with that utility, but it did with walkera. Now I have my own laptop so maybe it'll work for me now

Good luck, I hope you can work it out!
