Good advice Av8chuck..... Some serious homework is needed to keep on the right path with a DIY system and eCalc can provide great insight. As all up weight increases, it is important to get the motor KV lowered to optimize the efficiency so as to achieve maximum flight time.

I don't know much about the XAircraft MR offerings but the general rule is as follows: Smaller MRs with shorter motor arms tend to use higher kv motors. Whereas the longer motor arm lengths that allow for larger prop diameters use lower KV motors since lower KV is much more efficient especially...

eCalc for Multicopters has a limited database of props to choose from for direct performance comparisons between various propellers and the "PConst" factor that can be used for custom prop adjustment for the prop thickness... The help section tells you how to use it. But at the end of the day it...

There are a number of threads in both the Mikrokopter and DJI areas that indicate the addition of 3 degrees of cant on the motors will enable better yaw control. 3 degrees to the right for the clockwise and 3 degrees to the left for the counter clockwise motors makes the FC yaw self-control more...

To some degree you may be right. But I do believe that the new development in sensors starts with the larger image sensors then migrates down into smaller sensors. And if you have ever seen a top quality Hasselblad photo made with extra large sensor you will understand how much better and...

I did not make the best choice on the motors as I did not realize it was better to get the KV down when using larger diameter props. But more recently I went down the following path...

Move away from the PID loop control tuning and focus a bit more attention of the Martinez deadband adjustment, sometimes referred to as the available motor torque adjustment within the configuration software.... small ripples can be the result of too much available control torque getting to the...

I am having difficulty tracking down a good fit-for-purpose 2 or 3 axis BGC system to be used with a Panasonic GH3 or GH4 c/w standard weight lens(es). There are many developed for the NEX and similar weight/size of cameras and many developed for the heavier SLRs and even some for the Red Epic...

Agreed the guy is dangerous..... if the news item is in fact being reported accurately....... But if I understand the original article correctly the incident occurred almost one year before the CTV New break, i.e., April 2013 versus April 2014! Maybe its a slow news day! Meanwhile the photo and...

The GoPro3 and 3+ do not use a conventional 5 pin mini-USB cable except for basic charging and data downloads to PCs. But if you look carefully at the GoPro3 mini-USB connection you will see that it actually has 10 pins. Also for the GoPro3 to to put out live video to your FPV video downlink...

I heard from a local dealer that DJI can't keep up with worldwide demand largely due to a shortage of skilled workers for their manufacturing facility! Business growth in excess of 20% per month!!

Guess again... I used to run a small but international electronic repair business...... it's a failure by some businesses to make an effort to find less costly shipping arrangements for their foreign clients as well as a federal government issue with border restrictions. Note that this issue...

Canadians beware of HobbyKing USA Warehouse shipping costs: Buying a $20 ESC from HobbyKing International warehouse will cost you $22 c/w shipping, customs/excise etc. But buying the same ESC from HobbyKing USA warehouse will cost you $50 including shipping, customs/excise etc. HobbyKing USA...

Thanks Jes1111 In any case it has been a mistake and/or subsidized in my favor ongoing now for well over 2 years with RCTimer but also several others suppliers from various parts of Asia..... The one major exception is the international shipment of Lithium Polymer batteries.....

North American shipping costs between adjacent countries for same size parcel, i.e., 4 x 4 x 2 inches: $12 to $15 USD International direct shipping costs from Singapore to any North American country: $2.00 USD. See attached image.... Just wondering how North America can compete with that!!!!

As a matter of interest/awareness here is a comparison of the cost of shipping of a small light weight parcel approx 2 x 4 x 4 inches in size. Based on personal experience over several years: The cost of a regular postal service shipment between countries within North America would average...

Z is the vertical plane, x and y are the horizontal planes..... +x is the righthand side of the MR when the front of the MR is pointing away from you. +Y is the front of the MR etc.

subpar, How much for the RED Freefly Systems Vibration O-rings?

I do not use the DJI built in gimbal control so...... Previously when using a separate RC Receiver with my WKM, I simply would connect a spare Rx output channel directly to my BGC so as to remotely control the camera pitch angle. But with the A2 built-in DR16 receiver, how do I map it so as to...

That is a very interesting question..... If the MR is being used for commercial business purposes such as aerial photo/video work.... is the FPV system being used within the HAM frequency band(s) meeting regulatory requirements? Keep in mind that the regulations require the operator's call sign...
