I want to buy the new EVO V coming out from Tamiya... pondering do I want titanium screws or aluminum screws? what's the difference?

Since the bulkheads of the EVO V will be aluminum... if i have aluminum screws will there be anything i have to beware of? are there any special ways to make sure the screws don't come out?

How bout aluminum bulkheads and titanium screws?

This is my first high performance RC.. (i have a ta04, but back then... the bulkheads were plastic)... so i would want to know more.

thx for helping me out.

Alu is a hair lighter than titanium

But titanium is a lot lot lot more stronger than alu.

When screwing into metal, we all must use blue colour liquid loctite...

The aluminum screws look a little better in my opinion. But, they strip very easy, and their a pain to get out. Titanium is harder to strip, and you can crank down on them to make a tighter fit. You really can't crank down on the aluminum screws, eventually you will screw up and strip them out.

Thanks for the reply...

I will sacrifice beauty for strength in this case...

titanium it is. thanks for the replies.

I have another question... anyone have a picture of something about how much loctite is a good amount of loctite?

If TAMIYA makes a screw set for the EVO5(I am sure that they will)I'm sure it will be the same as others set for TAMIYA cars. For the MSX, it's titanium on the bottom and aluminum on most of the top. I think the same goes for the TA05(not sure).

I agree with Juan, aluminum do look nice but can strip or brake easy. I been using both ti and aluminum on my MSX with no problems. If you wait for the screw set, it will be cheaper than buying different sizes. I am sure that Steve at speedtechrc will have an all ti screw set when this car come out.

Also, are tamiya "titanium screws" pure titanium?

i mean... if they call them titanium screws because its 10% titanium... 90% combo of cr*p (soft) metals.... it still doesn't make the screw that tough....

I don't know if most screws out on the market is 100% ti(maybe someone will know). You can still strip out ti screws if you are not carful. I never put any loctite on my screws. Just makes it harder to take out if you want to rebuild or align something. You also need a good 2mm head tool! Get Hudy or something just as good. Cheaper tools will strip the screw heads.

If you want to use Loctite on your electric ride, just put a couple drops worth on a plastic lid of some sort and dip the tip of each screw in the Loctite. Then dab the tip of the screw on a dry part of that lid to remove excess Loctite and screw it in place. Dip, dab, screw. Dip, dab, screw. It should be more than enough to secure your screws and you shouldn't have any problems when you have to unscrew them.

All titanium is an alloy made up of many metals, don't worry even the "weakest" titanium alloy is strong enough for R/C use. Although you may still get the odd titanium tierod breaking, the screws are should last for years.

I have some Lundsford Ti fatboy motor screws that have outlasted a few cars, and I'm sure Tamiya's quality is quite good.

Pure Titanium weighs .1621 pounds per cubic inch.
Pure Aluminum weighs .0975 pounds per cubic inch.

Titanium is almost twice as heavy

Definitely go with titanium, it is an amazing metal. I have a titanium bicycle and it rocks. It is made from 3/2.5 series titanium, which is an indication of the added percentages of aluminium and vandium. this is added to make it stronger/harder. There is also 6/4 Ti. Pure Ti often originates out of eastern europe or China. It is still good, but often a little softer and less strong. If you can afford it, get the ti, you wont regret it. And dont be too concerned about weight, it will be negligible, especially with most modern cars we are adding weight to make standards.

For comparison,
Steel weighs .283 pounds per square inch.
Vanadium is .202 lbs/sq inch.
Uranium is .6753
Gold is .6969
And the heavy weight on the list. Iridium at .8096. So a 12" by 12" by 12" block of Iridium weighs in at a whopping 1204 pounds.
