Choose your frame carefully - it's better to over engineer and always have more than one.
Frames can be the most deceptive of items to choose. The trick here is not to fall for gimmicks. So choose designs that make good structural sense and will stand the trauma of the oof bounce. There are actually many frame designs available, some cheap some very expensive, but really few that will prove to be strong and useful. The issues here are usually around torsional strength in the arms, strength of the base plate required to hold all the arms together, availble space for components, motor mount design and camera mounting options. The rule of thumb is to choose a frame that offers the best combination of strength and versatility with room for future expansion. We have added worthwhile designs below for you to consider.
Bear in mind that you do not need to purchase the complete frame if you are handy with tools. If you are willing to do a little fabricating with a hand drill and some nuts and bolts this is what you can do:
Start by buying the MK base plate. Two of these will cost $15 (US) and will prove to be one best purchases you can make.
Whether you decide to build the frame with them or use them as templates to drill Aluminum or CF plates they are a terrific item to have.
|Next you go and find some aluminum tube for the arms. 1/2" square tube with a decent amount of wall thickness is about the best stuff. Don't waste your time chasing round CF or T-Rex 600 tail booms. The square aluminum tube (12mmX12mm) lets you bolt the motors directly on the arms and this is by far the most reliable and accurate means of mounting the motors.|
|Once you have the basic frame together you may either decide to buy the landing gear or make your own or buy some readily available landing gear like this. These skids are cheap and look great.
|Once you have the frame together all that is left is a means of distributing power to the ESCs and a means of securing the flight controller board to the frame with some vibration dampening. While there are many ways to do this it is important to note that unless you have good vibration dampening you get yourself into all sorts of strife while trying to control your drone.|
|The frames below have actually been tested and proven themselves worthy of recommendation
You can buy a complete frame from Jakub like this little beauty
(These are very well made and will stand a lot of punishment provided you don't overdo the punishment)
Jakub makes a number frames of varying sizes. All are worth buying. If you would like a frame that you can use and re-use and customise and fix when you bounce the Quad then get one of these.
There is site where you see all the frames and order them too.
You can also buy these others from the MK (Mikrocontroller) shop
