Hi I was thinking of putting some stuff lying around into a CCPM TREX and was wondering ....

How big of a motor do I need for good Power...?

I have a Park Flyer 3700KV brushless and TP 1320 LIPOs ...
Is that too small... ?

I have one GY240... Will that work or do I need the 401? I'm just learning to fly so it won't be much bone crushing 3D besides the odd loop etc

Just wondering Thanks!

the 240 and the 1320 TP will get you by and hovering. Not sure about that motor. You can get a good motor for 45 bucks (Align 430L) ESC should be 35amps. At first if you have a 25amp one, it will prolly work though.

Gyro is fine..

Battery a bit small. Probably have trouble getting more than about 6 mins.

Don't know about the motor, but with that kv rating you could try it with a 10 or 11 pinion and see what it's like. Is it a 400 size motor?

Bit smaller

I think it is a bit smaller than a 400...probably a bit weak...

I am looking for a good combo for Rocket Power type performance...I was just wondering about the stuff I had around here all ready...thanks..

I have HS55s and there is quite the debate whether they are good enough or not on here LOL...

What is a good tail servo?

Oh ya...I have an electron 6 rx?

Also is the Gy240 no good for anything past hovering etc...Seems most people are using 401s...any others using better yet?

Thanks for all replies!

If you are just learning to fly you don't need the power you are asking for so the motor you have the 3700 kv will get you started with a decent li-po

The world is round you can run but you will always end up where you started from

only real differences between the 240 and the 401 are:

401 will take a digital servo--240 takes analog only (i think it'll still work with a digital servo, just not in digigal mode, if that makes sense)

401 is a little heavier than the 240

401 has remote gain (uses a channel on your TX)

other than that they are essentially the same gyro.

if it ain't broke, break it.

I think that there is an additional difference between the gy240 and the gy401.
The 401 allows a faster piro rate than the 240.

Yeah that big fat 401 weighs sooooo much more than the 240, it weight a wopping 1 gram more (Gy401 29g, Gy240 28g)
