Force 1 f200w is technically a Bugs 2 rebrand I believe just with different paintjob package contents, I guess.
but the price for bugs 2 is like 300-400 dollars.
you can probably get a cheaper brushless motor drone with GPS & altitude hold drone at lower price.
First thing, it's cheap follow by extra one battery in the package. Next it is much latest model that have better controller software or software.
User Quadcopter also flies DJI spark, I think its a good drone if you into photography and ease of control. but personally I don't recommend getting it as your first drone despite being very easy to control.
because ease of control doesn't mean it does everything automatically, u still need to know how to fly them when there is a need.
I admit dji spark is better model.
For the OTG cable part. Technically the remote controller and Phone signal both uses 2.4ghz for communication. But there is a high chance of signal interfere between both, resulting in possible losing control of the drone or lose of video transmission which both Could end up badly.
If i am not wrong Bugs B2W and Force1 F200W Shadow able to use 5 ghz for communication. That's why I wanted to purchase Force1 F200W which is less costly and have some better spec compare to dji spark. The battery life is better for Bugs B2W/Force1 F200W compare to dji. But eventually Bugs /Force 1 and DJI is different level and should not be use to compare.
For fly-aways, most GPS drones need to calibrated every flight. and also make sure that GPS connection is good. (6 and above if I am correct)
From most video I watched, they recommended connected to 10 GPS.
Having a good pre-flight check can help prevent fly aways.
Just test if your "Home point" is set correctly, take off the drone fly forward for 10-15 meters ahead and hit your "return to home aka RTH" that should automatically bring your drone up to a certain altitude flies to the GPS coordinates and descend to land. (RTH altitude can be set in the DJI-GO app I believe)
If the drone acts abnormal instead and goes off in a different direction. it should be within your visual range, so you can override RTH and manually bring the drone in.
Yup saw one of the spark user from youtube where he talks alot about the safety of flying a drone.
I believe if the drone fly away not resulting of your mistake, DJI will replace your drone or repairs if you sign up DJICare I think. I seen few examples on youtube that DJI does honor that as long there is no mistake on your part.
Depends, I saw a few that did not managed to get a replacment. The log from the drone and the controller data don't tally eventually the owner not able to get a replacement.
probably the Qoo10 local seller are not earning much from the bugs 3 drone

generally most of the drone stuff is cheaper elsewhere. qoo10 is usually better if you want to receive the item faster.
Hmmm did I made an error, the price in GearBest and Qoo10 is as such: $155.45 vs $129 (not including shipping and no camera for both).
Shipping I think GearBest may cost $20-30 cause ship from China compare to Qoo10 that cost $4 from Singapore.
