A set of the new Spider Gear was in my mailbox nestled in a USPS Priority Mail cardboard envelope when I got home today. Nice...more stuff! I had already made plans to fly today so I figured I'd just check the contents.
Here's the package that was in the package.

And the contents.

After flying, I started checking over the contents. Beefy! Definitely solid. The struts have sort of a crinkle coat to them that finishes nicely. Up close, the ribs that span underneath the heli's frame is a little rough on the inside of the lightening holes, but the more exposed outside of the ribs is good. The struts use a slotted spring pin as the pivot which is pressed into the strut. In between the strut and the rib is a plastic bushing. The spring pin slips through a hole in the rib and is retained via a shaft collar. There spring spans between the two struts on either side of the rib. There's another smaller spring pin in each strut which stops the spring from pulling the strut too far.
So how does the Spider Gear compare to the stock gear (see pics below)? Well...it's definitely heavier. My stock gear with screws and all (as pictured below) weighed in at 29.9g (1.06oz). Spider Gear weighed in at a whopping 123g (4.34oz). The skid diameter is .250" (6.35mm) versus the .207" (5.25mm) of the stock gear. Skid length is approximately 8.5" (216mm) versus the stock gear's 7.5" (190mm). The Spider Gear's stance is also wider coming in at 5.5" (140mm) as compared to the stock 4.5" (114mm). Ride height with the Spider Gear is also a little higher than stock at approx 1.800" (45.7mm) versus 1.70" (43.2mm) stock. With the rubber on the rear of the skids, it actually lifts the tail a tiny bit.

How about a cheesy function test? I took a 13 pound power supply and set it on the Spider Gear on my counter top (with the gear's rear rubber removed). The power supply had enough mass that gently setting it on the gear would not compress the gear (stretch the springs) as shown here.

But if I gently slid left to right, the weight of the power supply did compress the Spider Gear right around half way.

Now is 13 pounds worth of support overkill? I doubt it. I'm sure someone with more time than I could calculate the force a little Rex can generate at full negative. Anyone? I was hoping to do some drop tests with a weight equivalent to that of an airworthy T-Rex, but I didn't have the time or the high speed camera which would have made it much more interesting.
Assembly was straight forward even though there were no pictures or instructions included. I mean come on...it's landing gear. How tough can it be? After removing the stock gear, I lined up Spider Gear's bottom plate to the T-Rex's landing gear mounting holes and they lined up nicely. The plate did have a slight bend to it most likely from shipping, but was easily straightened. I pre-assembled skids to the strut assemblies and starting with the rear strut, I ran a screw through a rib, through the bottom plate and threaded it into the frame. Oops...looks like I gotta cut a zip tie that I have wrapped around down there. No biggie. Three more screws and the the strut assemblies are secure to the frame. Then, with the skids loose, I slipped the rubber skid ends in place along with my heaviest battery and the canopy to check CG. I didn't check CG before removing my old gear, but I'm pretty sure that my CG shifted slightly forward. Not a problem though as the skids can be slid fore and aft to help balance the Rex. Last step, secure the skids via set screws. Be sure not to tighten the set screws too firmly as the aluminum skids mar easily. And don't forget the thread lock! Oh, and the Spider Gear also had a nice spot to mount my whip antenna.
So...how does it look? Judge for yourself.

Overall, the gear definitely feels solid. The articulations work well on the bench and the spring rate should provide ample shock absorbsion to help cushion a bird from potential peril. This does come at a cost of weight though. No flights yet. According to the 10-day, I may not be able to fly till Thursday due to wind. I need a big shed!
More to come after a few flights. Thanks for the cool gear design Matt!
