Hi all,

i am going to take the TRex jump as soon as the new swashplate is available and I am still debating on which motor to go for.

I was going to go for the usual Mega 16/15/3,but had second thoughts since the NEU motors came out AND I already have a Mega 16/15/3 in a pylon racer,so I could always take it out to give it a go in the TRex.

The NEU motors offer a nice weight saving but I am confused because i see all sorts of different numbers posted here.

Why would everyone go for the 1105/3Y with a Kv of 3500 when the 16/15/3 has a 3000 Kv or so?

I am going to run it with TP 3s 2100.

Also,what is the MH3500 i have seen posted here? is it the same as the 1105/3Y?

Should I go for the 3Y with a 2.3mm or 3.2mm shaft? which pinions are easier to get hold of?

Finally,will the 1105/3Y not pull to many amps for the TP packs on a 3s config?

Many thanks for taking the time to answer my questions.

Guillaume

ps:where did you get your NEU motor from?

The Neu 1105/3Y and MH3500 (old name) is the same thing.

KV simply means how many revs per volt, so a 3500KV motor will spin faster given the same volts. (If you want the same headspeed you need smaller pinion with 3500KV)

Get the one with 2.3mm bore. http://runryder.com/helicopter/t156354p1/

It will work fine on 3S.

I bought mine from www.flydma.com but TP Packs have a combo deal on them.

I run a Kontronik Jazz 40-6-18 but that is overkill. I bought it so I can go 6S later on. Right now I use 3S TP2100s because I have a lot of them.
