I am contemplating on buying one of these after market frames.

(1) I was wondering, how well do they stack up against the trex 450s?

(2) the main shaft/mast area 'looks' kind of weak to me ... is that going to be a problem in a crash (as compared to standard Trex frame)?

(3) what are the problems associated with these frames (besides the problem of not having it at local hobby stores)?

look forward to your feedback ...

hopefully your advice will save me money

Aluminum in frames, IMAO, is a bad idea. Once crash and you could bend something, not notice the bend, and chase the problem down for a long time before finding it. The same problem esxists in aluminum head components.

Also, using that much aluminum in the frame will probably make the individual parts expensive to replace.

With that said;
is that going to be a problem in a crash
A/C should be built to fly and not crash. They would be far to heavy if built to withstand all types and severities of crashes.

The real question you should ask is what advantage does that frame offer over other aftermarket or stock frames?

well, i was looking at this frame (3dx) and also the HDX frame.

the 3dx frame looks very accessible (to servos, tail pulley etc.). i am not sure if the HDX frame is also made of aluminum or not. i like the servo config on both of the frames

stock frames are great, but i think the servos are easier to get to in these after market frames, which i really like

Thats not a good selling point for me. I own heli's to fly them not to easily work on them. But, to each their own.

i crash quite a bit ... lol. seriously though, i do crash quite a bit trying to push the envelope a bit

i have the HDX frame for over a year now, and it withstood the rigors well. the aluminum parts on it do strip, and i have to work around that issue. i have had stock trex frames, which work fine ... but the aluminum parts strip just the same as the HDX

everytime i repair, the HDX frames are a lot easier to work on ... that is why i am looking for frames, which are easy to work on - and at least as sturdy as the trex

the mast on the 3dx frame looked un-supported to me ... that is why i was wondering if it can take some degree of abuse - can it?

that mast protrusion would put quite a moment onto the main aly frame. It seems to me that the mast may not give out but the main aly frame supporting it would surely bend pretty good.
