Opinions on the <$50 quad frames from GoodLuckBuy?

I was planning on doing a DIY frame with square aluminum tubing, however I'm ordering the MWC lite board from GoodLuckBuy anyways so I'm very tempted by the $25-$50 quad frames they are offering. Does anyone have any experience with these?

The first 2 seem very similar, for $42 and $32 respectively. They have neat spring loaded landing gear, folding frames. I think they are fiber glass and not carbon fiber, but the price is right:

Now for $25 they have this one, which I believe is the one that is always out of stock at HobbyKing. The price is an insane $25, and it includes "LED lights" as a free gift. Landing gear is not spring loaded. I don't think I could do a DIY for less than $25 in parts.

I'm quite tempted to get either the $32 one with square arms, or the $25 one with the carbon tubes. But I wanted to see what the group thinks?

This will be my first quad. Eventually will be putting my 5.8ghx vTx and camera onboard, if that is any consideration.

Thanks!

Or consider the hoverthings.com frame from http://www.hoverthings.com/frame-sets.html

In Canada, these are sold through http://www.flitelab.com.

I've used the hoverthings frame on 2 builds and can recommend it.

IMO, Order two of which ever one you decide upon, one for spare parts. Both looks good but I have no personal experience with either.

I have the X525, it is ok. Nothing fancy, missing/random bolts in the package. No instrustions, not that you really need them. Its ok for the price I guess. Just be prepared for a barebones frame thrown in a box that may not have all the parts.

The spring landing gear looks "neat" but its pretty much useless given how weak the springs are, and how it is setup with only an inch or so of travel. I doubt it would aid any in a rough landing.

How "strong" would you say the frame is? I know that one good crash will destroy even the strongest quad frame, but I'd like something that will survive minor crashes.

I'm leaning slightly towards the X450 because I think it's more sturdy / crash resistant.

I like the look of the round tubes better, but I want to mount LED light strips on it for orientation, so I'm thinking the square frame will make that easier...

Decisions, decisions...

not "that" cheap, but it looks really nice for the price. You still need to buy two because of spare parts I guess

Exactly!

Not only does it say it's made from "Friber grass" it then goes on to say "2.8mm Aero plywood laser engraving"....

So it's either fiberglass, friber grass, or plywood...

I just assembled my X525 frame. I have not flown it, but I can admit that it is a nice looking frame. I think one nice thing about it is that the arms are 1/2" square aluminum, which I THINK I can get at my local Home Improvement store such as Lowe's or Home Depot.

I read someone else describe the springy landing gear as "hokey". I agree. I don't see it really softening landings, but if one were to loosen the hinge screw enough, I suppose it might help.

I don't like that it does not come with any reasonable method for adding a dome or something to protect your electronics.

The ability to fold it (kinda) is neat, but they should really change the design to incorporate a folding method similar to Jakub's frames! His frames are a bit more expensive than these.

An alternative that I both HAVE and could recommend is Rusty's MQ-1 frame found here.

It is made in the good ol' US of A, and gives the user a LOT of flexibility. The only negative on the MQ-1 is that you gotta find your own arms. If you have a local hobby shop that sells the Align Trex 450 booms, then you're in business! You should be able to find a pair of those for less than $10, and they are long enough to cut into four arms EASILY. The advantage is that it is light, high quality, good lookin, and easy to repair after a crash . . . plus it protects the electronics . . . sorta.

Once I fly the X525, I'll add to my opinion of it.

You get what you pay for with these frames. And please dont hook some childs face with that terrible landing gear. Sharp points on flying objects yikes!

There are better frames on there I would avoid that one.
