Thanks a lot for your answer that's gold to me really,
In front I ll have:
- The APM
- A Larson scanner ( http://evilmadscience.com/productsmenu/tinykitlist/152-scanner ) [ Yeah I know that's so geek but I believe that would look awesome with the predator paint in black ]
- An IR Camera for FPV I m not sure which of these 2 models below I will choose yet it depend of how much load the Predator can take.
First one is near 500Grammes ( 17.6 ounce ) [ http://www.aliexpress.com/product-gs/431578085-IR-Camera-with-1-3-i... ]
Second one is around 200Grammes ( 7 ounce ) [ http://www.aliexpress.com/product-fm/365741534-Security-CCTV-Camera... ]
In any case I will need to counter-weight so I can permit some extra weight in front, if anyone is interested in the cam above, I used to work in my previous job with the first model and the quality by night is quiet awesome and they are not as big as they seems on the pictures.
I have the tech specs somewhere if someone want them just drop me a line.
Since I m here anyone could orientate me on the kind of brushless I should use to send this 4kg bird into the sky ?
I ve seen a rule of 150w / Kilo but I m not sure if it was kilo and neither how to calculate this.
Thanks a lot !!
Don's right, you are building a rock!
Plus, this model has a difficult moment of balance as it is.
Pick a diff airframe, one based on practicality, not romantic looks.
Everyone seems to want to start with the Predator! Sheeeez!
I wish you luck. Perhaps it will work.
For a laugh, and maybe something to think about, watch this video.
I think the first question that needs to be asked, which has been over looked, is how much flying experience do you have Shekou?
It's one thing to place a plane up there, it's another to be able to do that time and time again with the same plane, if you have years of flight experience I would say go for it, any plane can and will fly given enough skill and power, however if you are lacking the first part and have enough of the second you best be ready for some delays between flights while waiting on new airframes being delivered.
The plane which you are talking about has some very interesting flight "issues" at lower speeds, tip stalls. These are very hard to recover as they occur most often at low level and slower speeds, or landings as some would call them, loading any air frame up with a great deal of weight will always increase the speed needed to keep it up! So fast landings will be the order of the day.........
