First Try at Building/Buying and Flying a Multirotor

Quadcopter vs. Tricopter
You have to purchase and extra motor and esc
extra complication of additional servo, all props are same rotation direction in some layouts eliminated the need for opposite hand props.
Here is an interesting write up about the pros and cons of tricopters and quads and advantages a tricopter has in tilt prop layouts

Programmable transmitter, custom firmware from deviation that unlocks additional transmission protocols. However some protocols require the addition of a physical transceiver board. People commonly use multi rf cards (like this one) that have the hardware for multiple transceiver boards inside and allow for a greater number of supported. (guide to installing a tx module)
Devo 7E Module Installation
I purchased the board from Amazon, but the Banggood product page has a decent walkthrough on the installation of the module. It requires opening up the Devo and soldering on to exposed pins and contacts on the back of its main board.
The connections are explained decently by these pictures from Banggood
The view below is what you will see when you remove the back of the transmitter (There are 5 hex screws holding the two halves together.). Although, in this picture the shield has been removed from the original Devo radio module.
Making connection 13 is quite difficult compared to the rest of the job. To keep from bridging the fine pitch pins, I covered all of the other leads on that side with pieces of masking tape that I moved into place with a hobby razor. This left only the second connection exposed and I was able to tin the lead and solder it without too much trouble.
After the physical modifications, you will need to update the firmware of the transmitter. In my case I already had an older version of deviation, so I just had to flash one of the most recent nightly builds (I tried first with the official Devation 5.0 release, but my module was not recognized. After trying a few different things, installing the most recent nightly build seemed to solve the issue. I also tried the build with 256 in the name which didn’t work. Go for the one that just says Devo 7E. i.e. “deviation-devo7e-v5.0.0-e47daa9”). The Deviation website is very helpful for this. I used the wiki and the Devo 7E manual.

Tiny Whoop Side Project
BradWii is a project to flash cheap off the shelf quadcopters with more capable flight controller software. It has been ported to the Hubsan X4. You need an STMicro programmer for the installation. Github page here
Cheap clone of the Inductrix quad. It generally sells for $10-$25. Will bind to a Devo transmitter with deviation(custom firmware package) and the appropriate transceiver module.
You can also buy aftermarket flight controllers that will give you more ability to control the characteristics of the quad like the Beecore
Link to a blog post about the E010
Technically not a tiny whoop as it does not have ducted props, but it is generally well reviewed and comes build out of the box. Options for DSM2, Flysky, and Frsky. It can also be bought without a receiver.
