The Trex flies about 50% more stable than with the stock gear
Wow! thats amazing, why do you think that is?.

a landing gear is not going to make a helicopter fly any better...

I have used the Spider Gear through several battery packs and find them to be very efficent and the extra weight, I welcome. The Trex flies about 50% more stable than with the stock gear.

And for the Gorilla gear users. I have broke a set of those when flying in 20 degree weather. Any plastic gear when it is cold will break. It wasn't even a hard landing, just cold and rigid.

I believe this is a good product and if you have doubts at least try a set or talk to those who have.

I also bought a set of the plain X-Gear landing gear. I liked them as well and the Rex still flys better. When the Spider Gear came out I wanted the extra cushion for my not so perfect landings

sounds like a testamonial from X-Gear himself.

It's funny that you can claim that the heli flies 50% more stable with your landing gear. Are there gyros in there? How exactly does it make it fly more stable?

Added weight is not good on a heli this small. Period!

hey umd,

That testimonial is from a friend who has one of the first proto sets, I think he was trying to say that it is more stable on the ground as i dont think it should matter too much in the air. The extra 1 1/2 ounces hanging from the bottom can't hurt for stability in the air though, but i can't prove anything there and i won't ever say anything i do not know for sure.

Like i said, these are targeted to new and intermediate heli pilots that want to fly more and fix less. Higher skill levels are not going to want the added weight (i agree with everybody whole heartedly on the added weight). I'm supplying a niche with a way to learn more while having less costly accidents. I was there myself too, getting frustrated spending all kinds of money fixing things and wondering if i could ever do anything more than hover. I've broken several align gear resulting in the usual bent and broken other parts.

in my opinion extra weight on a trex is never a good thing.just going from thundertiger prolite battery to V2 packs made a big difference due to weight.
but it looks like a cool idea for sombody just learning.if the gear struts on stock plasic units both break in a hard landing the next thing to hit is the blades.so this could save cost of repair and down time.

another thought if you want to move your CG lower for stability reasons you can do so by mounting battyer pack on lower part of the frame without adding weight.rolls will be more barel like though and will require alot of cyclic to make them look good in little trex.

For all you guys complaining about weight, I highly doubt that 1 1/2 ounces would make a noticeable difference even for 3d pilots. With all these insanely powerful e motors nowadays, a couple of ounces is a featherweight.

It seems like I always fly a turd. . .

The difference I see between your trainers and the Styrofoam ball trainers; is yours cost and weights more, but look nicer.

Seems it should be made from carbon fiber to reduce the weight. The tube for the springs your seeking could be shrink tubing, just not shrunk.

The bottom line is having fun.

You obviously are not into 3d cause you wouldn't be saying weight doesnt matter.

It isn't only power to weight that matters, it's also the disk loading.

You are wrong. An ounce and a half on a bird that weighs somewhere around 32 ounces is a lot. An ounce on a .90 is squat.

May not seem that way if you pay more attention to weight. 1.5 ounces is approximately an 8% increase. Going off the factory specs of the 450 se v2 with power supply at 690g. (28.3g in an ounce)

That's alot.

Don't believe me? What if you had a 120lb wife or girlfriend who gained 10 lbs. (9.6 is exactly 8% of 120) Think you'd notice? I know I sure would.

WRONG!

I realize that weight does matter in 3d but 1 1/2 ounces is not that much.

Like I said, if you truly realized the performance impact of increasing your flying weight by 8% then you wouldn't be saying that.

The math and the numbers don't lie. A heavier helicopter on the same size power plant and rotor disk area is not going to fly better than an otherwise equivalent lighter one.

1.5 ounces matters a lot to a heli this small.

OK, may be I should get a free one to promote it and do a mad 3dz video with it on just to prove you naysayers wrong

Well I think they/he/she should. This way they can have rr supremacy. Every time someone mentions springy (based on springs not elastomers, polymers, rubber or plastics)landing gear this forum will be the originator. ATTN Mr. Inventor Guy: You're not gonna get better pr than this. To the best of my knowledge this is your first post advertising this on rr? Well it's demonstration time!

allright guys, your on, I'm needin pr and a good vid anyways. dart, email me your address at xgear@clearwire.net, I just picked up some Kandy blue powder that actually looks better than the anodized blue on the rex's, i'll do up a set in that and send down to you. I am offering an option though to use the stock align skids to drop the weight, but i need to know though so that i leave the holes in the arms small (I'll include my skids of course, to use them, just drill out the holes, its up to you which skids you want the arms drilled for though)

I think for a beginner this is a bad idea, a hard landing on one skid on a normal helicopter they may get away with, it will probably come down on the other skid right after, but putting springs in it, I can see this thing bouncing all over the place, I would say it would be 50/50 as to whether a beginner has a worse crash with this or a less damaging one.

TBH it looks like a case of making a product for the sake of making a product.

Sorry.

mavrik, I'm going to start work on a carbon fiber version. one thing that im unsure of is carbon's brittleness, a glass fiber version may be a better way to go. either way, the minimum thickness would have to be 3/16 (to have enough room on both sides of the mounting screws)I'm not a composites guy, so im going to have to get some assistance on that one for R&D.


BadKarma, This is not a trampoline, there is enough spring rate in these that it doesn't bounce all over, I could take this farther and and shocks to it, but then you have more weight which would get flamed as well. If you land on one skid with full negative pitch and land as hard as you can, then yes, what happens will be unpredictable.

Spinky, Thankyou for good words
