Title: Help needed for Multi Rotor Setup
Post by: yashodhanp on September 03, 2013, 08:02:45 AM
Hello guys, I am planning to build the Baby FPV and Mini Spider Hex

http://wiki.openpilot.org/display/Doc/Open+Frames+by+jbkappirossi%2C+MikeH%2C+Kristjan%2C+A*Morale%2C+Snagglesworth

I would like to know what would be the ideal setup for the Baby FPV for getting 10-15 min flights?

And what setup should i use for the mini spider hex to get the best flight times?

I was planning on using the M2222/31 for the baby FPV, is that a good idea?

can you share the link of the motors and other electronics that you plan to use. Flight time depends on what motor+esc combination and lipo you use. Also depends on the total weight of the frame.

I planned on using the m2222/31 from RCB or the cf2805 from RCD, couldn't find any other suitable motors for a 5" prop

RX will be a FrSky 8Channel Reciever, and lipo will be selected last depending on the weight and flight times i would get

I would suggest you to try with smaller one and note the time then if you can increase the weight of the quad then go for higher mah lipo.

i did some calculation the frame with all electronics excluding LIPO will weigh around 450 grams, and the motors will generate 1kg of thrust total

Thats good, so consider that you will be flying with max 80% throttle. But try with small lipo once, you will get it.
