ISDT ESC70 - new brushed crawler ESC with BT-programming

I recieved mine today and after soldering the connections on it,I hooked it up . When I power it on,all it dose is flash red! I checked every connection and still nothing! I'm not too impressed so far.

Sounds like you did something wrong, flashing red on most ESCs means it's not getting signal from the receiver. Could have simply got a bad one too but I'd make sure everything is working and wired correctly on another esc.

I must have missed this ESC70 thread, as I feel like I absolutely responded in one. It's been 10+ months since I suffered through the debacle that is the ISDT ESC70, and I still get a YT comment once every couple of weeks from people saying theirs "works perfectly." Well, good on ya. But everything in the chain is flawed-- software, firmware, hardware. Mine never worked quite right, and now sits in the box it came in, likely never to see rocks again.

The final straw was that the ESC would somehow spontaneously lose calibration, disable the motor, and say nothing of it. So I'd power the rig up, have steering, but no throttle. Would have to launch the app, hope it would connect, then delete the ESC from the app, reconnect, and start over as if it was the first time ever using it. I would do this sometimes more than once a day. Different radios, different motors, different servos, nothing mattered. If they've gotten the bugs ironed out by now, great. But they don't exist to me. The venerable 1080 just works. The actual best part about the 1080 might be that it doesn't have an app.
 
I finally gave up on my esc70. Last week I took the Wraith out to crawl. I ran into an issue when I tried to dial up the drag brake for crawling. I had only used the wraith for trail rides and never needed the control of higher drag braking before. Basically i couldn't get the drag brake to hold the car still on even a moderate hill.

It might be an issue that the 10t 550 crawlmaster sport was too much motor for the drag brake, I'm not really sure. The guys on the isdt fb group with working escs seemed to have strong braking in theirs so maybe mine is not working as designed.

Anyhow, the drag brake works perfectly now. Problem solved.

I have 2 original 1800kv Fusions and a 2300kv Fusion in 3 of my rigs and 1080 escs in 7 of my brushed rigs. Never had a single complaint or failure with any of them. I was on the fence about trying this new ISTD thing shortly after it was released. Very happy that I gave it a hard pass.
