TIPS FOR A LONG HEIGHT FLIGHT

Fly on a clear day, sunny, without clouds, without or with little wind.

Charge the batteries well (control and drone).

Fly in places with NO AIR TRAFFIC , if you are flying in
local with some traffic make request according to local laws.

ABOUT MODIFICATIONS
Height limitation of 500m: removed

Control passed to FCC mode
* Increases the control power from 0.5 to 1.5 watts

Automatic return to Home Point when alerting
low battery: removed
* Be aware that the drone will not automatically return
for you when detect low battery you will have to do this manually or trigger the RTH.

Modified in DJ Assistant 2 (old version):
(1 meter = 3,28 feet)
Ascension speed, in Sport mode: changed from 3 to 7m/S.
* I had put in 8 m/S but I saw that it was forcing the engines,
giving constant warnings of maximum speed reached. So I decreased
to 7m/S and solved it. So he only warn Max Speed ​​Reached when there is
some wind hitting him.

Descending speed in Sport mode: changed from 2 to 8 m/S.
* The drone drops very fast even at this speed. It’s practically
a free fall. If you are going to use this descent speed, decelerate
slowly when lowering, because otherwise it forces the engines to brake
and he loses a little bit of stability in doing so. I do not recommend
walk forward or sideways, decreasing at this speed.

Comments:
I let the GPS mode speeds the factory setting.

I used homemade deflectors made from RedBull cans.
I think they can help improve the signal.
You can easily make one at home or purchase over the internet.

I used the OTG cable to connect to the controller.

Screen rec app is DU Recorder.

The battery consumption of my Spark going down at 8m/S in a day
without wind, it is approximately 10% every 1000m.
When descending, the engines use between 15 and 20% of their capacity.
Unlike the climb, where they use between 70 and 80% (without wind).
So I consider it a safe margin to go down from 2kM – 6,5kFT with the battery by 40%. Lowering at 30% is a little riskier, but I also believe be possible to be done.

Remember!
If you are going to do “long heigts” do it on days with little wind
and preferably without clouds. There is an account of a brother who flew
above the clouds and his Spark identified then as being the
floor and was not getting down through them. After going down in a very slow speed he managed to get out but, it’s a big danger, because you waste to much battery, so be careful!

I checked after the flights, with my hands, the temperature
of the engines and comparing to other flights ,they didn’t
look overheated to me.

Can modifications cause problems? I think so. For a while
I didn’t have any. I think it’s important to have videos like this to exchange
information!
Any questions ask in the comments!
Hugs from Brazil!

DICAS PARA UM VÔO DE ALTITUDE

Voe em locais SEM TRÁFEGO AÉREO.
Se tiver tráfego aéreo solicite o vôo no SARPAS.

Voe em um dia de sol sem vento!

Carregue bem as baterias do drone e do controle!

Use defletores! No meu caso usei defletores caseiros feitos de latas de Red Bull

Através dos tutorias indicados modifiquei a velocidade de ascensão do modo Sport de 3 para 7m/S e a de descida de 2 para 8m/S.

Limite de 500m de altura desbloqueado.

Retorno automático por bateria baixo retirado. Assim o drone não voltará automaticamente ao HomePt. ao alertar sobre bateria baixa. Conheça bem
seu drone antes de utilizar esta modificação!

Controle passado para o modo FCC. Aumenta a potência do controle de 0,5 para 1,5Watts.

Utilizei cabo OTG para o vôo.

Observações:
Meu Spark está utilizando cerca de 10% de bateria por kM de descida, em dia sem vento. Creio ser seguro baixar de 2kM com 40 ou até 30% de bateria. Ao baixar a 8m/S ele utiliza cerca de 15 a 20% da potência dos motores. Ao subir a 7m/S utiliza entre 70 e 80%.

Eu havia colocado a velocidade de subida em 8m/S mas estava dando muito alerta de MaxSpeedReached, assim baixei para 7m/S e resolveu o problema, só dando o alerta ao subir com um pouco de vento.

Baixar a 8m/S é praticamente uma queda livre. Se for realizar esta alteração freie devagar na descida para não forçar os motores não desequilibrar o drone.

Verifiquei que os motores não aqueceram mais que em vôos “normais” voando com estas alterações.

É possível dar problema? Sim. Mas por enquanto vai tudo tranquilo! Vamos trocar ideias nos comentários e bons vôos para todo mundo! Abraços!

  1. Há vida la fora!

    NO BATTERY MODIFICATION IS NEDDED TO DO IT! You can go with an original good one ;D
    One more hint! I don't recomend flying above the clouds, because the Spark can identify them as being the ground. So you can't go down with your drone! It hapenned to a brother and fortunately he could go back trough the clouds at a very slow speed!
