If they have done there track testing as well as they could,then the car sounds promising and has many features(at least in print)that other cars don't have.
If they haven't fully done there R&D then they will be in deep $%#@ !!!

About the laydown throttle.I read an article in an rc car mag talking about laydown servos and if they really help.It ended up saying that in most cases that it does and some it doesnt.In my opinon the front servo layed down is more beneficial cause theres only so much you can work with in the front as far as the throttle goes Serpent lowered the engine(more wgt) in the chassis which would help alot in cg and maybe they tried the throttle and found that there was no benefit but remember the engine has been lowered which is much heavier than that of the servoand cant forget the smaller flywheel less rotating mass.

In fact I think the current position of the receiver on the G4 is too near the engine which makes the tendency for a lot of unwanted frequency disturbance.

The 710 spots a 33 mm diameter flywheel (or so we are told) which would make it mounted 1 mm lower than the 705 (based on the 35 mm flywheel diameter on the 705). If indeed the 710 spots a 4 mm chassis (can anybody confirm this), then it could possibly make the engine mounted back to the original position as the 705 with a 3 mm chassis.
Hence that could probably explain why Serpent could use the 705 tank because of the same profile...

I deal with Lee on all my Gas related things hes been in the nitro businees and selling Serpent among others for yrs,He always has the parts Ive ever needed and if not Id have them by the end of the week so some of yall who are looking for a hobbyshop that has all the Serpent parts contact him(Lee) He even has a toll free number to call and he knows his business Great guy to talk to.

When it comes down to it, I don't think there is an advantage either way.

Just in from Serpent... One of the few articles to come by in the 2 weeks to come. This should answer most of our pop quiz questions concerning the front portion of the car ! 
New front end design
The front end of the Serpent 710 offers some very attractive features:
- quick change system of the front transmission, you can change from front shaft to front ball- differential (optional)in just a few minutes time
- front shaft with one-way bearings, which offers the option to change it into a solid front axle (more on this innovation lateron) within seconds
- new front suspension arms, very strong and rigid
- bigger size and high quality pullies
- roll-center adjustments made easy (more info lateron)
- front carbon shocktower with a variety of shock-mounting positions and a 3rd body pole in the center with newly designed pivoting body-rests
- front eccentric belt-tension adjusters (around the front bearing)
- centrally located servo-saver and steeringsystem with center-shaft system
- very open and easy to access front end design
- high quality allen type fasteners
More news on the front end and other parts of the Serpent 710 in the next days.

I'm a little fuzzy on the polar moment thingy but I'm thinking since the throttle servo is already placed more towards the center of the car, polar moment would not be much of an effect when the throttle servo is laid down, wouldn't it...serpentracer1 brought up a good point about the change of CG when you lower the throttle servo. It does not make that much of an effect when you compare that to physically lowering the engine which is in many times more heavy than the servo.
So perhaps what you conclude may be correct that laying the throttle servo does not bring more benefit (more hassle in fact) to the car's handling. Furthermore if what is being said about the increase in the polar moment when the throttle servo is laid down to be true, then it really serves no purpose. I guess it gives the "nice to look at" effect and a slightly lowered CG but nothing else.
Perhaps this is why the new Kyosho 1/8th scale (Evolva) does not spot the laid down throttle servo like the 950R...

710 HEAVIER OR NOT HEAVIER?
now i am wondering..... is 710 really heavier than 705?
coz... the chasis is 4mm compared 3mm in 705.
then MODELLOR said 3 wishbone will make it more heavier.
then the pullies are bigger
then they add 3rd body pole
why they wanna use 4mm chassis instead of 3mm?

The new one dose not mount to the front bulk heads.
