I like to add my setup

4225 scorpion 610kv 12t pinion
130 scorpion
Bls255
Bls256
Vbar
625 main radix
95 tail radix
2s 1300 spyder
12s 4000 spyder
Sick canopy

I think for a 12s heli it comes in pretty light. This heli is a lot bigger then your normal 50..

It's not per say a 600. The 635 designation and the ability to run 625 and larger blades really puts it in a different class. It does any maneuver with ease.

There are some things that could be done, reference my setup posted above, to reduce overall weight.

- Ditch the regulator and run a small 2S lipo direct with HV servos. Also get rid of the two esc trays. All of this might pick up 4-5 ounces at the expense of higher cost servos. Stay with a lipo rather than a LiFe battery because LiFe is heavier.

- Replacing the 4350 motor with a 4225 saves 2.5 ounces.

- Flight batteries are where the weight is and that is where you can get the most savings, but it isn't free. Replace the two 6S4000's with 6S3300's and you save over 6.5 ounces, at a cost of about 1-1.5 minutes of flight time.

So, it is certainly possible to get well under 10 pounds, but reduced flight times are the likely result.

I agree with Marshall that it is a different class machine. One of my friends has identical 700 and 635 machines, and I really struggle to tell them apart in the air. The 635 has lots of presence.

True for the size ... not a 600 ... a bit bigger so I guess it's kind of normal to be a bit heavier than a regular 600 ...
Kenny, what's your flight time with 12S 3600mA ?

Flydynamics,

I'm certainly not going to argue that two equally powered helis, one lighter than the other, have the same flight dynamics. But with regard to your point about tail slides and gravity, remember the old high school physics book: objects in free fall (like a tail slide) fall at the same rate and reach the same final velocity independent of mass (weight). We could work out the equations, but drop a ping pong ball and a golf ball at the same instant from the same height and they will hit the floor at the same time. It's counter-intuitive but true.

You are right Dr Don, Gallileo made it clear with his experience on the Tower of Pisa some centuries ago ;-) and Newton stated F=ma .... I guess I spoke too fast without thinking of it !.....
I stuill think lighter is better ... more nimble, more easy on the packs etc ....

I didn't think of the size to be honnest, like said in my last post (the short one), it's not a 600 size heli but more like a little 700 on steroids which raise my interest again for this machine ....

I LOVE my Rave ENV but I'd like something a little bit lighter, more nimble, I could use my Rave ENV canopies. I know it's possible, the Ballistic 700 and the 635 has the same frame I guess, (Feel free to correct me if wrong) and use some parts of the ENV as parts in the eventual case of a crash happening.
I like the servos direct swash, better than the ENV lay-out (especially for elevator servo) and cheaper battery packs ...

Speaking of pack, what's you flight time on 3600 ? 4000? please.

thx guys

I'm getting about 5 1/2 minutes on the 4000's, but I don't fly hard 3D like Kenny does. My flights are more flips, rolls, big sky loops, swoopies, tail slides, a few tic-tocs. Kenny's data on his 3600's may be more useful to you.

I weighed mine with a fishing hook scale. So I'm not to sure how accurate it is. I'll try my buddies postal scale as soon as I have a chance and report back.

Getting 4.5 mins on my 4000's too

Flydynamics,
Flight time on my 635 depends on how I fly. Most people around know me for smooth flying. Here lately I have been pushing myself harder so I am not stuck in a box. My point is that, battery usage is greatly dependent on you.

So for smooth flying with a HS of 2150 I will typicall average 2600 to 2700mah of usage. Of course that is big air stuff. If I throw a lot of collective at it and do a lot of tic toc or hard manuevers with it I will put back 3300mah plus in the pack and get just less than 4.5 minutes.

Honestly I think the pack is a tad to small. I would prefer a pack that was 3800mah just to give me a little more head room. If I could get to the 85% usage range but still fly a bit harder that would be great.

Now if I take the head speed down to the 1850 to 1950 range I can go closer to 6 minutes depending on the style. Now 1600 and smooth I can fly even longer but I don't really remember the numbers for that.

The point is, I am having a blast with this model!

Thanks Kenny, of course headspeed and aggressivity will determine flight time, your post is pretty clear for flight time to expect ... thx again
