Holy Sheet

OK the DRR allready is a decently fast car, but in the quest for all out dominace I made adjust ments }:]

1. HPI micro modified motor
2. 7.2 volt 350 mah batter pack.
3. ALL bearings!
4. Foam tires
5. Titanium rear axle.

So you sau Scar how does your new DRR run?
I say HOLY SH_T man I couldnt run this car inside if I lived in a mansion!

This car is faster then my Tmaxx on the street! its skips a little bit due to rocks, but I just brushed them up and out of the way!

SO MUCH power in fact that with foam tires and rouch concrete tit STILl will and does spin them if I gun it!

I am waiting on the 30 shore tires from IRC now and a new body.

I have never in my life seen a RC Other then big 1/10th scale nitros run this fast..

NOW only if I could speed check it in MPH.. I am guessing so is my friend at roughly 25MPH if not more...

I can run at 16 mph and it blew by me and my dog cant keep up with it..

Sounds fast! Which HPI motor did you use? Is it the 180 style? And where can I get the axle?

IRC,

http://www.precisionmodelproducts.com/id34.htm for the axle..

Its the HPI micro modified motor is allI know GRIN
I guess its the 180 since its for the rs4!

sounds awsome man. Just imagin what 1100mah would do!

Also, I don't know if you have done this yet, but try adjusting your intoe to keep it form spinning out as much.

Hey Scar - what kind of run time are you getting with the 350mah battery and 180 motor?

Thanks.

Scar · #6 12-15-2002, 10:52 PM

Honestly Not very long 8 - 10 minutes..

thats wide open throttle!

binaryterror · #7 12-16-2002, 11:51 AM

1100 mah batteries would only extend the run time.

Siress · #8 12-19-2002, 11:25 PM

Thats what I thought up until recently but its not right.

Mah is the punch you get out of batteries actually. If you don't believe me run 7.2 volt 250mah AAA against 7.2 volt 1100mah or even 650mah or so, you will notice a dramatic diffrence.

irc · #9 12-19-2002, 11:55 PM

mAh stands for Milli Amp Hours and has to do with run time. An 1000 mAh battery should have double the run time of a 500 mAh battery.

binaryterror · #10 12-20-2002, 06:17 AM

mah is only run time. sure a better mah MIGHT give you a longer and more consistent run time/speed, but it is all about the volts and amps that matter with speed and power differences.

Also a new pack is better than an old one, as is a matched pack.

Siress · #11 12-20-2002, 11:19 PM

I stick to what I said.

Adam · #12 12-20-2002, 11:46 PM

They are right, Mah, is how LONG a battery lasts, NOT how strong it is. The amps are the strength measure, when paired with votage of course.

I dont mean to argue BUT, think of all the kids who dont know this, They come to the forum and ask us, IF we tell them the wrong answers what good are we. If you are going to give advice, KNOW what you are talking about.Most of us are over 20 here so we know a little.

Siress · #13 12-20-2002, 11:56 PM

This is what I clearly heard from a person I consider an "Electric RC Master," he really knows his stuff. I will ask him how I should explain it clearly to everyone. I will get back to all of you guys with it later. Mostlikely after the holidays.

Adam · #14 12-21-2002, 12:07 AM

I have no wish to prove you wrong, I just dont want people to get the wrong information. I took 3 years of manufaturing Technology in high school, I still have my Tech II book and this is explained in it, so I think I will stick with the book.

Man oh man I can't wait to get my DRR and play around with the hop ups. I haven't had a RC (besides my Microsizers I recently bought) for about 10 years or so since I was a kid. I'll probably get my DRR on monday!

I'm new to the micro scene and I have some questions about the hop ups. What are the advantages on adding the bearings and titanium rear axle? I was also wondering about how to do the 7.2v pack upgrade and where to get one reasonably cheap?

On another note, I'm not trying to disagree or prove anyone wrong either (my knowledge of RC's and hop ups are very limited)... but everything I've ever read has ALWAYS referered mAhs as being the storage capacity of the battery. Take a look at http://store.picturetrail.com/pages/rechargeables.shtml near the bottom.. here's a copy & paste from the page ;

Key Battery Terminology
mAmp Hours (mAh) – Refers to the electrical current expressed in milli-ampere-hours that the battery can support at a given voltage. The higher the mAh, the longer the battery will last between charges.

Capacity – Measured in Amp Hours (or milli-amp Hours) and is the amount of time the battery can supply current at the necessary voltage.

Milliamp Hours (mAh) – Refers to the energy the battery can store. The higher the mAh, the longer the run-time between charges. One mAh is the equivalent to 1/1000 Amps. And 2.7 Ah = 2700 mAh

The page also states this :
When purchasing rechargeable batteries, the higher the mAH number the better! That is, 1800mAH will last longer than 1600mAH batteries. mA is the electric current that flows out of the battery and H is the number of hours.
