Those are fairly different batteries. Especially since the voltage difference ist quiet high. If they are the same geometric size you can expect the LiPo battery to have at least the capacity of the NiMH battery. Most likely even something like 50-150% more. The power output will also be a lot...

The board you received is without a doubt not originally intended to be used with a H920+ but with a H920. You can see this by looking at the connectors as well as the fuses which have been changed from 40A to 60A somewhere during production of the H920 and changed back to 40A when the H920+...

I build several drones all ready but they were based on frames meant to do this. I thought about doing this to a H920 but I have not been able to source a good donor aircraft. Either they were crashed or came together with all the accessories I did not need and were too expensive. I do not see...

And furthermore how long has it not been turned on before? Especially after not being used for a while they need a lot longer to acquire GPS. Maybe it just needs a little bit of patience (15-30min). Afterwards it will work just fine and a lot faster.

This can be caused by vibrations. Especially after a crash this is very common. Take a look if you notice any vibration or if you can see one or more motor shafts wobbling around when turning.

There is not necessarily a need but usually it is the best choice to do so. If you arrange them in a 90° angle you will have the best signal strength on average. If you plot the radiation pattern you will find that you have the smallest overlap when they are arranged that way. This supports the...

What works great on planes is using aramid fiber or glass fiber instead of carbon fiber in areas where internal antennas have to penetrate the hull. Since those have hardly any dampening effect on electromagnetic waves you will have plenty of range. Furthermore they are often even better suited...

After sitting a while it is very common for GPS modules to have issues finding their position. This is due to the reason that the connection data is stored in a memory chip which is powered by a small (usually rechargeable) battery. If this battery is drained, which happens over time, it will...

That is a fairly common issue on the Typhoon H series (all share the same mechanism). The endpoints are determined by the current flow. Therefore it might misidentify a mechanism which is harder to move than usual as one which already reached the endpoint. After a crash this might be caused by a...

Good to hear that you found a new camera for your bird. Nevertheless I would not mount it for the first flight since they are the most fragile part of the drone and usually the thirst thing to hit the ground. The airframe on the other hand is quiet robust and also very easy to repair. Without...

Mode 1 and 3 (gas on the right side) are great if you have a plane which has to be thrown on takeoff. Unless you are left handed you will usually throw it with your right hand while your left hand is on the remote. When the gas is on the right side you will always have control over the important...

Usually this problem is related to a dirty mechanism. When dirt sticks to the lubricants the mechanism will become harder to move. Since the Yuneec drones determine the end points by the current drawn it will stop the mechanism. Your method most likely worked because contact cleaner contains...

Although the rest is true I have to disagree on this one. Unlike DJI the Tornado uses ordinary LiPo batteries. They do not even apply a special case or connector like other Yuneec drones. As long as they fit in the battery tray and they supply the voltage and power needed you can use any battery...

Interesting idea but I do would not recommend doing it. Many microwaves burn quiet good due to plastic components being used. A friend of mine unfortunately made that experience himself and did quiet some damage to his kitchen. If you want to see some pictures of what microwaves can do just...

Those agricultural drones are huge. This one is about 1.6m or a little more than 5ft in diameter. In case you want to find out more about it, it is called M8A Pro and was made by a company called TTA. I am not sure if you can still buy it since the website is unavailable but it is still listed...
