Hey Guys,
Recent posts about classes and the upcoming race with a min. weight requirement brought this to mind. Some of the NTRA classes utilize the same chassis per individual class. While some permit different types. All the 4g can use a NOS or AW chassis. The only real difference between the two being the plastic used and t/mags. Maybe a slight difference in weight because of denser Nos plastic. Not sure never got around to weighing 4g's.
I have weighed the original (copper-clad) and a newer AW/t-jet. The chassis permitted in N/PS, Rat, Gasser and Pro Mod. The exact same builds on one of each of these chassis have a difference in weight of 1.7g's (copper-clad the heavier). Practically all of this difference in weight can be attributed to the brass gears. The four brass gears 1.6g's, the brass gear on the arm shaft is .2g the other three plastic less than a tenth. The rest of the difference maybe the plastic maybe the plates rivited to bottem of chassis.
I thin k the classes that permit either of these chassis need to be revised in reguards to weight. The upcoming race is a good example of why. The D/S, have a min. weight of 25g's. If all were equal, that being arms, mags, etc, etc, etc and so forth. Which would you prefer to run a car weighing 25.0g's or one closer to 27.g's. Think we would all go with the 25. And I think all would agree that weight is a factor to consider when better performance is the desired end. Be it the reduction of weight or the positioning of weight.
The economic factor considered when formulating the rules (as I understand it) trys to put all on an equal footing. Yet it leaves those trying to run a copper-clad in these classes where similar chassis can be run, at a disadvantage in weight. So if the rules should ever be reconsidered to address this. How are things made equal ?
Would a min. weight for all of these classes be the way to go ? If so should it be that of the copper-clad, requiring weight added to newer chassis ? Or that of the newer chassis allowing reduction of weight in copper-clad ? The fairer of the two seems the reduction of weight in the copper-clads. Adding weight would allow positioning, which could yet still be another advantage.
Don't get me wrong here. I love everything about NitroSlots. From being able to talk to the same warped minds (no slight intended) that want to make a toy car go faster. To being able to see the fantastic modeling skill on display in pics. is great. At times mind boggling and allways inspirational. The learning of new things through adds on the site or from other members can be hard to keep-up with because of the wealth of information available here. I've got body's now that a year ago I never drempt of having. Parts I never new exsisted. Like I died and went to HO heaven. So this stuff about weight is just me trying to polish those pearly gates.
Good luck to all at the races next weekend........PC

When we start worrying about speed over looks, I'll be done as far trying to race all the time. That's the exact reason I left 1/25 scale drags. TOO much complaining about the rules, and those rules being changed all the time to benefit the 'fast guys'. And it's also been one of the determing factors in molding my resin bodies to look as close to the 1 to 1 cars as they can be. Remember, this is a hobby. And, I believe it should stay that way. That's a PERSONAL opinion tho guys, so don't go wanting to shoot me for it...LOL. ;D Also, one other thing to consider. While there is a weight difference in the original, copper 4 gear chassis over the new AW chassis, the older chassis will FAR outperform the newer (and I've found that is true even with Tjet chassis). As well as the faster, original Aurora parts not fitting as well in the newer stuff. The level of quality control was never good on these anyway, as they were considered toys, but the qc level on the newer stuff is even worse.
