<p>I don't think that you can edit the throttle limit directly in the goggles, but you can change rateprofile in the betaflight OSD.</p>

<p>So what you can do is to set up a few different (up to six) rateprofiles in betaflight, and then change between those in the OSD. It won't be as granular as changing the limit directly, but it should be enough if you just want to change between a few different values.</p>

<p>Can you configure your motor output limit on betaflight or DJI goggles?</p>

<p>I know you can do it through the fatshark goggles, but I do not have parts to build a drone, so I am asking before I get 2700 RPM/V <a href="https://en.wikipedia.org/wiki/Motor_constants#Motor_velocity_constant,_back_EMF_constant" rel="nofollow noreferrer">K<sub>v</sub></a> motors for a 5 inch.</p>

<p>Formula:</p>

<p>LIMIT = desired K<sub>v</sub> / real K<sub>v</sub> * 100%</p>

<p>Example of the formula being used:</p>

<p>LIMIT = 1800 RPM/V / 2700 RPM/V * 100% = 67%</p>

can you elaborate? what do you mean by motor output limit? do you mean rampup power? maximum throttle? what exactly are you looking for?

Formula: LIMIT = desired KV / real KV * 100. Example: 67% = 1800 / 2700 * 100

@BastianSpringer, I'm basically trying to lower the KV of my quad motors so I can use  a 6s battery rather than a 4s battery. I do not know if lowering the kv of motors is dealing with rampup power or maximum throttle so i cannot answer your question. My question is, if it's possible to limit the KV through betaflight or/and dji goggles since i do not have a built drone to find out. I'm assuming you can through betaflight since you can do it through fatshark goggles, i just want confirmation. I hope that clarifies a bit.

Kv = [motor velocity constant](https://en.wikipedia.org/wiki/Motor_constants#Motor_velocity_constant,_back_EMF_constant) (AKA back EMF constant). Unit: revolutions per minute (RPM) per volt. e.g. 5,700 RPM/V.

# Motor output limiting

(Asked by: username_0 on 2020-06-06)

Can you configure your motor output limit on betaflight or DJI goggles?

I know you can do it through the fatshark goggles, but I do not have parts to build a drone, so I am asking before I get 2700 RPM/V [Kv](https://en.wikipedia.org/wiki/Motor_constants#Motor_velocity_constant,_back_EMF_constant) motors for a 5 inch.

Formula:

LIMIT = desired Kv / real Kv \* 100%

Example of the formula being used:

LIMIT = 1800 RPM/V / 2700 RPM/V \* 100% = 67%
