well i destroyed my brand new tacon 3674 1900kv

Yeah I guess it could be just a bad motor. Either way I ordered a leopard 1700kv and two 5s packs. I feel more confident this will get me where I want to be, reliably. I'll start with 440/3 or x442

That sucks, would have been nice to know if the motor just failed or over heated.

I got that same motor on the way so ill see how it runs, on 4s with a 1.14x42 prop.

Hope your new motor works out better for you.

Well I got my leopard from ose today. Threw it in and put a x640 on there to start. Ran great and motor was very cool. Compared to the tacon which got very hot on any prop I ran. Thanx leopard.... Gonna try some different props then try 5s.... Nice

I think you had a bad motor... i just ran the tacon 3674 1900kv in my apparition yesterday, ran great. After 5 min of moderate throttle the motor was only at 105. Was running on 4s with a 42mm prop. I will push it harder later this week and see how temps are.

Hmmm.... Sucks for me I guess. Is yours the orange or green can? What timing are you using?

[penz]

Green can, they don't make a 3674 1900kv in the orange can. I believe my timing is at 30, thats if the menu tree for my esc is correct. According to the esc instructions timing of 1 is for high kv motors, you were running 3, that could have been an issue... But you have no temp data so we will never know... illupdate how mine does under hard throttle.

Just wanted to chime in here too. I run an orange Tacon 3674 1300kv on 6s in my mean machine and it moves really well with a x642. I have yet to GPS it but its faster than my 32 Fighter Cat single which hit 45.3mph with a Castle 1512 1800kv on 4s. Temps are all around 90-100 degrees after a 4 minute (mostly full out) run in the Mean Machine, timing is set at 15. I like the Tacons as they have treated me well for the rock bottom price. Was thinking of putting the 1700 or 1900kv into the new Mystic and see how she goes.

I just had another good run with this motor, temp at 105... Im going to eventually put on a bigger prop.

Here is another thread about other users thoughts on tacon motors.

This thread sounds like an esc problem, but i believe you just got a bad motor, and it can and has happened to any brand...
