Alert
Be careful with this setup, battery burner

I was out flying with my club last week and with this setup, a $80 battery was ruined

Neu motor (not sure which one but it has the little shaft on it not the new bigger one)
Kentronics Jazz
TP 2100 3s
14t pinion THIS IS WHAT DID IT!!
6v bec dont konw who makes it.

Ok so we were flying on sunday and my buddy decided to run the 14t pinion on his setup. He got through the flight and then, as he was landing, the whole thing went to full power and then shut off. not much damage but it did slap the sab blades on the ground pretty good. I am not a pro i am just trying to report this so no one else ruins batteries like this. This is an expensive so just trying to save my fellow flyers some cash

Big can or small can Neu?

Probably an 1105/3Y (for 3S) this is rated at 3500Kv... 14t for that somewhat high.. even with 13t you should be getting up around 3000 RPM HS.

I'm surprised it trashed the pack though.. should be good for a 35 - 40 amp surge.

yeah this is one of our better guys as seen here www.mattbotos.com and he puts a good bit of stress on his heli. he ran it on a 4s for one run and didnt like it and then he went back to his 3s and it started to balloon so we got rid of it safely

I run my 1105/3Y on 4S with a 9t... PQ1800Ns seem to cope, TP2100 is better.

When I first put my 400 together I used the 14t that came with it and a Neu 1105/3y. Thank goodness I didn't put the main blades on because we tached it at 3900rpm! What do you think that would have done for the amp draw?? I now run a 10t and life is wonderful.

Yeah 9t on 4S is great performance. I ran 8t for a while but it's hard to find 8t with a set screw... the pinions are just too small.
