really depends on your motor..
Not sure what most are flying but I can tell you this. If you are going to run one of the higher RPM modified motors, 16 is the only way to go. I begged Ali for one when I had my T700 and he kept tellin me no.. 2 days after I sold the 700, he came out with one..

But I believe it's really what you want if you're going TRM.

Hi torque, It's hard to tell what is the most used. They are experimenting their heli and it's better for you to do experimenting also. And share us the result of you experiment. Have a good one!

Mostly (including me) 17T is used. 6,76 is the best gear ratio for trex 700.

Mine I got it set up 1850 normal 2000 idle 1 and 2100 idle 2. I got used to it and in fact at normal now sounds to slow to me. But man I love the way it flys.

Good luck.

i am with you. i absolutely love my stretched 600hb. i have not started converting my trex700 into a gasser yet. i can't get over how much heavier the 700 is built. i don't think once i get my 700 built it will fly any better then the 600. the 600 has to be lighter and quicker i would think.

Torque...

You are right on the weight the t600 will be lighter than the t700. Mine is at 12pounds and its fast. When people see me flying in it they always ask... Is that a gasser Heli? I reply yes it is.

The advantage of the t600 is that you can stretch it and enjoy a 700 size with no problems and saving some weight. If you are looking to get into 3d this t600 stretch will give you what you need And more. This is just my honest opinion and experience so far with it.

It will be fun to have the 700 as well don't get me wrong I think it will perform excellent.

Hope this help and please let us know your findings with the 2 helis...

if i remember correctly i think you said your 600HB weighed around 12.4 lbs mine weighs around 12.6 . i bet the 700 would weigh in around 13lbs. i was wanting to build up another 600 HB but came across a good deal on the 700LE frame. so guess i will go with that.

Yes it was 12.4 but I put it on a diet...lol!!

I did some changes like put a bigger tank but a lighter muffler change the battery from 5000mah to 2200mah and now I got it to 12. I had the RJX muffler now I got the century torpedo half the weight of the RJX. I played around with different things and end up with what I have now.

I guess the 700 will be close to 13lb but if you want it lighter try to select what you pick to put in. See for instance the Aling servos weight about 52.5 oz check your muffler, battery, how much fuel you are going to put on. I got now a 16oz tank but I put only about 11oz on it. Try to make everything as simple as you can.

I hope this help and keep me post it as soon as you finish your baby.
