In the VDO is my night practicing session during a drone festival at Queen Sirikit convention center, Bangkok, Thailand.

It is my first official racing event. I can finished 3-4 laps as required in practice but when the real race comes I mostly did not finished the race. My time per lap is not good too. The best can go under 14 second per lap but my best time is 17 per laps. I learnt that there are many little things that made me not quite ready for an official race such as; not enough normally used-propellers (it's totally differ for 2-3-4 blades), use to same type of propellers all the way, better go early for a few practices before race, prepare for the worst crash and use the equipment that is easy to fix, bring spare parts, add a barrier in the front of your battery (my battery fly out of my drone once by sliding to the front), don't rush at start (for beginner), in racing they required you to have a laps caller in order to confirm the race is complete.

And make sure the camera angle will not tilt on an impact. 

Most of the problems will be solve if you have a drone mechanic with you.

And also if you do not crash at all most of the problems will not occurred. :|

DRONE RACING! This is so cool, @Oran.mike. Would love for you to post what parts you're using. You've got skills.

I used Storm SRD210 TBS cube and I also took my Kykin with me as a spare drone. The SRD210 is a bind and fly version so all the part is selected by the Storm. I will talk about the parts that I got problems with. 

1. Batteries. A week before race I got only two 4S 1500mah and two 3S 1500mah(3S is normally for the Kylin). I need more 4S batteries and the YGP battery was finished from the sellers at that time so I had to bought a high-end multistar gold 4S 1400mah which is more expensive.

2. Propellers. The stock props had 3 set(12 individual props) of 5040 4blades props. And at that time, again, there was no supplier who sell 4blades props!(I found out a supplier who just import that 4blade props after my race finished, what an irony). So I brought other kinds of props, 3blades carbon, 3blades bullnose, 2blades bullnose which I never used with SRD210 before. Imagine when I ran out of 4blades props during practice and got to race with never-try-before props. It's sad!

3. The camera. This is about the camera tilt angle which normally lock by 2 screws but that was not enough. When your drone impact to a ground(not just crash) the camera angle tilt down due to the impact force. I didn't lock the camera angle into place and got to adjust it most of the time. So the viewing angle I used for each race is a bit differ and again that's sad!

4. My Kylin ESC or the mainboard burnt. Due to the 3S batteies were charging so I chose to fly kylin inpractice with 4S battery which I know that there is more chance for the ESC to burnt than 3S. As Kylin is notorious about burning ESC and so hard to change ESC. And then a crash and smoke and yes the ESCs burnt. Now I got only 1drone.

5. The single bottom carbon plate of the SRD210 frame. Every once in a while when I start to get used to the race track and increasing speed there will be a crash. One crash was so severe that left-aft arm was broke luckily the motor still fine. The problem is a single bottom plate cannot replace just an arm, you got to replace the whole plate(4motors, control board, Rrx got to be removed and attach to a new bottom plate). I didnt have the spare bottom plate so I got to splinted the broken arm with epxoy putty, strabs and a new generic carbon arm bought from a seller around the racing tent. And now I flew with a broken drone.

6. The battery warning buzzer is dead. Since when I didnt know that the buzzer stop working and there were a few times that I flew until the battery completely ran out. So using an OSD that show the battery status is an efficient way of monitoring your battery level.

Well, lots of problems for a newbies.
