interesting thoughts about the center motor mounting.

does anyone find they are getting better results with their TA05 v's their 415,416 in stock?

Thanks for the input on the motor mount. I have a caliper but didn't bother checking what was out of wack. Guess that would have been the smart thing to do. On the other hand, I can't find the flanged bearings available anywhere so if they are out of spec, I'll have to find a way to shim them.

I tend to disagree about weight being a factor in stock racing. With limited power, the most gains in speed are achieved with shedding weight. However, we have a minimum weight limit which we enforce. The high end cars are all covered with lead weights which pretty much makes all their pretty carbon bits just that..... pretty

My car in stock form with NiMH batteries is a bit over the weight limit. Should be near the limit with a few inexpensive carbon reinforced parts from Tamiya and a titanium screw kit. May have to get a few titanium turnbuckles as well but not sure. The point is, why spend all that money on carbon chassis and other carbon just to add weight?

Which brings me to another subject. LiPo batteries. I see the same thing happening with them at the track. Our cars all have the batteries on one side. Putting a LiPo in the car makes it under weight as well as off balanced. So, you spend big bucks on batteries and chargers to run LiPos and end up adding weight back into the car. I run some old 3000mah NiMH batteries and have more than enough to get through a 6 minute race.

Interesting stuff, no?

Not if you go through hobbycity for your lipo needs! After discovering that place, I couldn't believe that getting a set of LiPo for cars actually comes out cheaper than using NiMH batteries, even if you buy the NiMHs that are onsale at hobbyshops!

However, I still have a fleet of healthy NiMH so I'm still using this "old" technology as well... My 3300mAH is more than enough for a good 10 minute run... It's crazy how little power on-road takes versus off-road since the terrain is not constantly fighting the motor in on-road...


As for the 840 flanged here you go:

Lipo's are night and day to NiMH in my opinion. Sure you have to add weights to make up the difference, but a lipo isn't just good for extra run time. They are more efficient and will last a lot longer than an NiMH battery would. A lipo also doesn't require discharging after every run. Some people use a lipo balancer, but really it isn't needed unless you run yuor Lipo into the ground.

Thanks for the link Tom. Avid looks like a great resource.

I know I'm going to have to make the transition to LiPo sooner or later. NiMH as well as brushed motors are going the way of the dinosaur. But for now, my old brushed motor and NiMH sport packs are good enough to get me through the winter in the stock class in the V2. This summer, I would like to get a SC truck and race in the dirt. So, I'll need to make the transition then. Can someone please educate me on the terminology associated with LiPo batteries? The only thing I really understand is the Mah number. What does 2s, 3s,....6s mean? how about the numbers with a "c" after them? I think we have a limit at our track that I have to get smart on before I buy anything. What packs fit well into a V2 or are the same size as a 6 cell NiMH?

Hobby City certainly takes the price out of the equation. Like anything else electronic, the price comes down pretty rapidly as the new wears off.

Thanks again for the great info.

Sure,

2s means two in series, 3s means three in series.

1p means one in parallel, 2p means two in parallel

25C means twenty five times the capacity for discharge rating. So a capacity of 5000mAH would give you a 125A (since 1000mA = 1A) discharge rating.

Each cell of LiPo are nominally 3.7V. So a

2s2p 5000mAH 15C would be:

7.4V pack made of four 3.7V 2500mAH internally (two pairs in parallel to give you the capacity of 5000mAH), with a discharge rate of 75 amps.

All the money you spent on the bulkheads and motor mount, you could have had a 416. And you wouldn't have to hack up an expensive servo...
