topcad?

[Greywolf74]

I've seen topcad brand aluminum parts here and there on Asiatees website for a long time but there seems to be more and more of them these days. I love the GPM aluminum parts but I was curious if anyone had opinions on the topcad brand aluminum parts.

Same for Boom Racing?

I've never bought from asiatees, although it does seem like a pretty big site and I've ran into it before. Personally, I'll only buy an aliminum hop up if its 7075 aluminium- if they don't list it then it might be 6061 or something still OK but not great.

 

[Greywolf74]

6061-t6 is plenty good and thats what GPM parts are made from but I've not bought nor have I heard of people buying topcad products or boom racing products from AsiaTees. I guess I'll have to email them and ask them what type of aluminum they use like I did for the GPM parts.

6061 is ok, for some things- but for things like shocks and chassis, I'd always go 7075 or titanium.

The GPM alloy is ok for skids and body mounts, not sure I would use the alloy suspension arms on a rig I run though...

A show rig?, maybe, A run rig? perhaps not.

I do know that the front body post mount for the revo needs some "tweaking" and a new support post to clear the rockers, so maybe some other items they offer may need tweaking a little?

 

[Greywolf74]

theres a big difference between 6061 and 6061-T6. The tensile strength for T6 is on par with base 7075 aluminum. Most of the aluminum on my LST2-E is GPM and that thing takes the most abuse of all my kits. 6061-T6 is aircraft grade aluminum.

Well, if that's the case then go with whats ever iss cheapest- even better would be titanium- too expensive for me though

I'm waiting for clarification but so far I've been told that the TopCad stuff is 6061 and the boom racing is 6065 aluminum. I'm waiting for them to clarify if its base 6061 or if its 6061-T4 or T6. T4 and T6 is good, base 6061 is crap. We'll see what they say. The 6065 is good. theres not a lot of info on the net about it. It seems to be an uncommon type of aluminum but the info i did find on it suggest that its on par with 6061-T6. I'll report back once they answer me. If its 6061 they might as well put Integy on it. O_O

To clarify one of my earlier statements I said that 6061-T6 is aircraft grade aluminum but while I was reading up on 6065 earlier I read something that indicated that base 6061 is also considered aircraft grade. For those of you that might want to quantify the difference in strength between 6061 and 6061-T6...Base 6061 has a max tensile strength of 18,000psi and a max yield strength of 8,000psi. In comparison 6061-T6 has maximum tensile strength of 42,000psi and a maximum yield strength of 35,000psi. Waaaaaay stronger

 

[ThunderTiger]

they are interesting facts in themselves and certainly clarify why all after-market componants may not be created equal.

6061- aircraft grade....maybe for the cup holders

Apparently its more for more homemade aircraft rather than commercial.

From Wikipedia:
6061 is commonly used for the following:

• construction of aircraft structures, such as wings and fuselages, more commonly in homebuilt aircraft than commercial or military aircraft.[6] 2024 alloy is somewhat stronger, but 6061 is more easily worked and remains resistant to corrosion even when the surface is abraded, which is not the case for 2024, which is usually used with a thin Alclad coating for corrosion resistance.[7]

• yacht construction, including small utility boats.[8]

• automotive parts, such as wheel spacers.

• aluminium cans for the packaging of foodstuffs and beverages.

• SCUBA tanks (post 1995)

nice info

Ok, I finally received confirmation that Topcad uses 6061-T6 aluminum for their parts so they should be good strong aluminum. If I ever find myself purchasing a topcad item. I'll post my opinions of it.

Are you going to give them the hacksaw test!?!?
The stronger the material the harder it will be to cut through.

I thought I read somewhere that topcad, and integy are manufactured in the same place.

 

[Greywolf74]

they can be manufactured in the same place and be manufactured to different specs.

What if you've got a blunt hacksaw?

What if you've got a blunt hacksaw?

Then you'll only damage the integy parts.

 

[Greywolf74]

I LOL'd

 

[hamz9561]

If you look real hard at an Integy part, it will bend.
