my research team has recently bought a 1meter wide carbon fiber frame that can hold 24lbs. since the frame can hold that much we want to be able the carry that much. mulitple gps units, better INS, airborn Lidar, ...ect. So i was seeing if you guys had any suggestions on mottors. i ve been looking at the e-flights and hackers but there on the expessive side. Not that money is an issue its more so is it over kill to have those type of mottors or not?
thanks in advance
I beleive in the power and the opensource community so plase dont take this the wrong way bloggers....
Does your research team have experience with building large RC aircraft? Have they at least built and master smaller drones before attempting this?Am I getting this right?-You want to carry 24 lbs of very expensive eqp such as lidar yet you want to save a few bucks on some crappy chinese motors. And why would you want to carry the same amount that the ariframe is capable of - thats just not good engineering - you will have weight of motors, ESC's, batteries, power distributions system (plus redundancy) etc that you need to factor in before you can even add the scientifc stuff. Not to mention you want to have some overhead to deal with the gforces associated with moving all of that wight around. Besides you havent described the requirements of the sytsem (what is the desired power to weight ratio?) Id suggest you go with name brands if you want to have any confidence whatsoever.Good practice is starting small and simple and slowly moving to a more complex system and then larger syste, What do you mean by better INS?.
Inertial Navigation System... which is basically a large mechanical precursor to the MEMS IMU.
A 24lb multirotor (*IS* that what you're looking for? You don't specify what type of drone.) is a complex, incredibly expensive undertaking which is probably not necessary, legal, accessible, or wise for the average student research team.
I'm actually in a very similar situation to yours.
My advice: Go make some friends in the Department of Mechanical and Aerospace Engineering. Invite them to intern for your lab. Learn as much as you can from them, and continue to read DIYdrones until you've got a bit better grasp of things like 'crashing', 'payload', 'safety', 'funding', and 'complete sentences'.
Obviously INS=ienertial navigation system, but what is meant by better?
Smaller? Cheaper? more precise? lower drift?Complete inegration? And better compared to what exactly?The ARDUIMU, ARDUMEGA IMU +compass + GPS?
thank you for all of your replies.
We are mostly trying to see what it would take to lift that much. We do not plan on lifting 24 lbs. right away nor pushing the frame to its limits. The purpose of this post is to ask the rc community what your suggestions are for motors, batteries, and motor controllers. We want to use the system to do on the fly survey grade photogrammatry.
@Scifly we are currently mastering and smaller version of the quad copter with four 200 series turnigy motors. Better INS meaning in the four figure range, and yes less drift, more precise.
@Ersin Acar we will not have the frame until next week. i will post pictures when we have it. We purchased it from www.rchhobbyhelicopoter.com it is made with 12k German carbon fiber.
