I would really like to know how the AHI, RTH and all the other autopilot functions compares to the DOSD.

I'm sure we will see resellers of the Rvosd very soon. So we all can enjoy this Great system.

Remember to make sure you reducere/remove vibrations from motor and prop. Too much vibrations = crash. Since Vova don't sell an anti vibrations mounth you will have to make one youself.

OSD received! EMS shipping rules - shipped to EU in only 5 days! I will report back as soon as I have flown with it, probably tomorrow morning if the weather is good.

Hey Alex, are you planning and when, to have in stock Plug and Play replacement GTOP FGPMMOPA6 10Hz GPS module? I am a very sloppy solder and I ruined the traces of one module already I will not mind to pay extra $$ for Ready to Plug GPS.
Cheers,
G

I guess some of you have read on RangeVideo's forums that Alex recommend a perfect balance of engine and propeller for the proper functioning of IMU. I have always balanced fixed propellers but frankly I'm not able to balance an engine and do not know a method to balance the folding propeller that I use on my FPV flying wings.

Have you a method to recommend?

Start by balancing the propeller, then check the vibration indicator. If it is ok you don't have to worry about the motor. Else balancing a motor is a bit more complicated, You can either buy a big name motor, or buy an NTM series motor from hobby city, like I did. They are balanced from factory.

It is important that the prop is balanced for both total blade/blade weight and hub (side to side).

An outrunner can be balanced by removing the can and using a suitable shaft on a good prop balancer.

A folding prop would be balanced the same as a fix prop but obviously the blades need to be somehow held out.

Now I'm waiting that RVOSD Gen.5 arrives and I will try your advice when it comes. Gary I see your mounting solution in RangeVideo's forum. For me it's a simply and great solution !!!

Gary, want to say that I have to remove the shaft to balance the motor and insert another suitable for prop balancer ?

You would need a shaft that fits your balancer. The OEM motor shafts are pretty short but if it works use it. If not you would need to find a longer shaft.
