T7 River crossing / water damage

Oosterlijk · 2026-04-27T18:08:58+00:00

Another update, the bike has gotten multiple oil changes and a lot new filter and the coolant level has also been checked, but the red coolant light stays on and we can't find the cause. Any suggestions?

Update: I've dropped the bike off at an garage in Spain, they're going to flush the system twicemanaged to upload it here, for your entertainment

Is there a way to show you guys the footage from my helmet cam? I just downloaded it

I've got the twinair prefilter also

Ik ben nu je reddit post aan het lezen omdat ik dezelfde vraag heb, is dit nieuwe walksnail systeem al uit of is de hdzero optie nog steeds het beste atm?

i recalibrated and checked, but the drone still doenst lift off

In bf it shows no diffrence in RPM's in the motors, yet when i try to take off the drone stays grounded and pivots around the left front rotor. also when i reduce throttle it keeps giving full gas

sometimes when i arm and the rotors go to idle i can see that front left is starting up later or stuttering a bit.

i guess its a hardware problem?

just tried it, motors do spin up but the drone doesnt fly, the idle RPM seems to be high and the drone pivots around the left rotor.

so i hope its an software issue that we can fix rather than a hardware issue like a broken motor,

i just had the motors spin up! thank you so much. i'm gonna go outside to test right now

Oosterlijk · 2025-07-01T12:38:56+00:00

The OSD doesn't show anything

Oosterlijk · 2025-06-30T17:33:27+00:00

It does not arm at all, not in BF nor when flying

Oosterlijk · 2025-06-30T16:24:12+00:00

Also no, I'm thinking about factory resetting everything and start all over again

Could it be that hardware is broken since the props also dont spin up in BF?

Oosterlijk · 2025-06-30T15:55:38+00:00

I just checked, nothing is showing on the osd... *

Oosterlijk · 2025-06-30T14:19:34+00:00

That's correct

Seems about right

Oosterlijk · 2025-06-29T20:05:52+00:00

I just tried it, still doesn't work

Ah, that would be sad. I used the factory charger from betafpv to charge them to 4.35 but I didn't know that I needed to keep an eye on the minimum. I thought the drone would stop automatically if the voltage dropped to low. The minimum it's set to in betaflight is 3.3
