Bumper Miracle Slide

[Tom Watson]

Anyone have one of Bumper's kits for the Cobra ramp they would be willing to part with? I tried to buy one from Wings and Wheels today and they said they are taking over the manufacturing and will be out of production for about two months.

[Mike Reid]

I bought a kit recently from Cumulus Soaring.

I've put the sliders on two cobra trailers. If you own a Cobra trailer, buy one of these kits. Amazing difference. German Engineering can accomplish a lot and Cobra trailers are true wonders but after adding this kit you'll just want to stand in the driveway all night and slide the ramp back and forth.

But, you'll no longer be able to freak out all the neighborhood cats
with that special screeching from the ramp rails ;-(

I've done two trailers, and believe one was the first outside of Bumper's immediate supervision. An excellent mod! As Tony implies, buy it NOW from whoever has stock.

What a great idea. Kinda tripping mentally over $15 for shipping though.....

It is so worth having, sometimes I just drive to airport, open trailer and slide/glide rail out to have someone run smooth in my life. Close trailer and head back to reality. It is like meditation.

Nothing beats the bump-bump-bump-bump-bump sound of a mid 80s Komet trailer ramp being pulled out. That takes me back to student pilot days at HHSC every time I hear it (if I wasn't flying, I was helping someone rig or de-rig). The metal/metal screech of the Cobra I just bought won't do. Can't wait to fix it.

Yes, I have an unused kit. Contact me at julietsix at gmail dot com.

Cheers,

I hate to rain on the parade, but a squirt of Tri Flow Superior (bicycle chain lube also specified for certain rotor heads) does a pretty good job.

[Tango Eight]

Installed this evening. Very nice. Pro-tip: a deburring tool is way faster than a file for taking the sharp edges off the tracks (but you'll still need a file for especially rough spots).

George, you're missing out!

Thanks for responding Jim. I bought one from Cumulus.

Also attracts and holds dirt. If you live in a gritty environment (i.e. Moriarty, NM) you learn to minimize the sticky stuff. Bumper's nylon rail guides do not gum up with abrasive residue.

Thanks for the reports on the SRS (Smooth Ramp Slider). In my quest to find more free time, I sold rights to the SRS, along with the MKIV yaw string and Quiet Vent, to Wings & Wheels.

BTW the SRS plastic slider is made of UHMW-PE, a long chain polymer has some unique properties, being almost as slippery as Teflon, yet is about the toughest most abrasion resistant plastic available. A one inch thick piece is said to stop a 45 ACP bullet. Should outlast the trailer - unless you spend your weekends sliding the ramp in and out. It is a "smile" after years of the Cobra ramp grind. :c)

Hollow point or ball? :-D

Armor piercing depleted uranium ball with tungsten penetrator. This stuff is able to pierce 43 pages of wet newspaper, no problem.

Define "depleted" :)

Depleted - Not all that once was. E.g. what happens to wind noise when you install a Quiet Vent, to altitude immediately prior to a land out, and to the grind after installing a Smooth Ramp Slider. :c) Mid 70's, not quite depleted, headed inexorably that-a-way.
