Any kind soul/serpent experts could help?

Thanks in advance.

New spring colors don't have the same spring rate of the old springs.

- Fuel consumption is higher at the recommended settings. I've noticed that with it the tank is almost near empty at the five minute mark (all other factors being constant). This is not good, but I believe I can remedy this by adjusting the pressure regulating setting.

- The device by design leaks oil, so there is quite a bit of cleaning after each run, and the pipe gets pretty dirty quickly. Since I am the type of guy that like his car clean, this is a real pain in my opinion.

So far I am willing to put up with the oil mess and as to the fuel efficiency I still need to play with the settings to improve it. I like the little gadget and will continue to experiment with it.

Since I just started using the device I am wondering how reliable it is and what its failure modes are. I guess only time will tell. Please let me know if anyone has had any experience with the device's failure mode.

I hope this helps.

Thank you for your input Erchur. I've been debating if I should buy one or not. Will let you know.

Anyone using the first set of non pro cvds? Ever notice this has allot of play in the bearing as compared to the fit of the stock dogbones? U think the new pro shafts fit the bearings better? I noticed this problem from the first day i built my car.

Default Dj alperto

Hello there,

I am new to this forum and i have made a recent thread named "Guys i need help from experienced drivers"..

all of the guys were very helpful..they told me to buy the xxxmain book to make my 720 run well...

they told me that there is someone called dj alperto and he is very good and helpful..

basically my 720 07 is a car that whatever i tried on it the thing is nervous and unforgiving..and i asked if i buy the new kyosho or the nt1 will it be better..

in the thread i made they gave me a link of the 720 going amazingly good and thats how i want my car to be...

the car there seems very forgiving and it goes like a train..

The 720 08 is a very tuff car, the only time ive broken it is when ive let the tires go to low and in a high speed sweaper i skated out to the wall going about 60mph and hit the wall, and in this accident(my fault by the way) i only broke a hub carrier and lost a spring retainer. Both of the new cars 960 and 720 were improved in durability and made more user freindly(easier to work on). Both of these cars can deliver when it counts, two of the best cars on the market.

didrace,

I have run the MTX4, VRRR in the past and have been running the 720-08 for almost a year now. My experience is that the plastic parts on the 720 do have the tendency to break easier relative to the MTX4 and VRRR when in a hard crash against the wall .

This is not necessarily a bad thing, in fact it is good; this is why in my opinion. While the MTX4 and VRRR plastic parts hold up better in a hard crash, these two cars have the tendency to bend the chasis easier than the 720. The 720 plastic parts do absorb much of the energy of the crash while breaking, which is not transfered to the chasis, thus avoiding it getting tweaked.

I have broken a fair share of 720 right lower control arms and left rear lower control arms and pins, but I have not ever had to replace a tweaked chasis on my 720. I much rather replace a $6 plastic part than a $90 chasis (which I did a few times $$$$ with the MTX4 and VRRR).

All three are good racing cars and each has its own peculiarities. I happen to like the 720 becasue the car is light, fast and easier to maintain in top racing condition.

Erchur

p.s., BTW, after almost a year of running the 720 I am still using the original belts, while I had to the replace the belts in the VRRR every other race ($$$$).
