So, the Pro VII is about to come out, which has a few extra goodies than the current Pro, and the current Pro has goodies over the regular TB04 (which there doesn't seem to bemuch discussion about.

Question - Are the Pro's worth the $$ over the regular, and will the Evo6 be worth the $$ over the TB04?

If your going to buy trf shocks and cvd's alone for a regular tb04, your better off with a pro v2 because you also get the aluminium ball studs, turnbuckles, cf shocktowers, hex head screws and high torque servo saver.

As for the tb evo 6, can't tell how much of a deal it is until we know the price

It's the same as the XV01. Basic has the body, Pro has the alum bits, CDVs, and TRF shocks. I always prefer the Pro so I don't need to fuss with buying those hop up.

The Pro II also comes with the new 418 arms which is a plus. Tamiya also addressed the misalignment issue of the prob shaft, so it's another plus

I like the plastic chassis. Do you think the stiffer chassis is going to help a lot?

got mine down to 1427g race-ready...
weight reduction was mainly from a lightweight body (NSX2005), a mix of alum and Ti screws. (note: however i do have some 30g of weights on the battery side as the LiFe pack we use is too light).

other lightweight tidbits would be the gear diff outdrives, replacing the front with a spool, and the upcoming aluminum drive train parts. The TRF418 arms are also reportedly lighter than the reversible ones.

I want to use a shorty lipo as that can save 100g easily. However, I will have to put the esc on the battery side and even then balance with lead weights if needed.

What would be a reasonable tolerance for left to right balance if running in 21.5t blinky? For example is one side is 20g heavier would I feel it? Unfortunately I quickly notice when one side steers better than the other and it annoys me.

I would run a short battery never in a 4wd sedan. In an off-road car or a F1 they are fine, but the weight penalty is a small price to pay for the amount of power they give up after a minute or so if the amp draw is sizable.

I'm all about getting the weight down to the class minimum, but even I won't use a shorty in a sedan.

There's probably 40-50 grams to be saved in the driveline with the new lightweight parts. If you dump the gear diffs for a spool and a ball diff, it's another 25. I'd look another place to pinch grams.

I already have 2 nanotech shorty packs from my previous project and I want to give them a try at least. If they don't perform, they will make good practice batteries.

I'm finding it difficult to plan my build as far as 'weight management' goes because I don't know exactly how much a tb04 chassis weighs (without electronics, body, tires). If anyone can give me a number, doesn't have to be millimeter accurate or anything, it will be greatly appreciated

Is the carbon reinforced chassis usually lighter?

According to Tamiya's descriptions of other platforms that, it is lighter and stronger than stock
