Product Description
Not too many years ago the joy that we R/C club flyers experienced in owning and operating two-stroke glow engines was taken away. Whether we liked it or not, we were driven to use exclusively electric or petrol power systems in our models. Not anymore. SC two-strokes are back, better than ever and poised to indulge your passion for engineering and your desire to enjoy all forms of R/C propulsion.
Enjoyed by owners due to their easy starting, endearing handling, smooth running and clean throttling, an SC two-stroke engine will enrich your R/C experience no end. That's a fact. Boasting a beautifully cast matt-finished crankcase with twin phenolic bearings, a sturdy, single billet crankshaft and twin needle carb with, in the most part, rear-mounted main mixture adjustment, these are engines that look good and run beautifully.
Fit a smooth-running SC two-stroke to your latest build and you'll not only be adding variety to your R/C life, you'll be adding guaranteed satisfaction and a hint of nostalgia.

They stay out! No more sock wads!
Size: Medium, Color: (100) White / White / Mod Gray
Best no show socks ever made!!!!! I've been struggling for 2 years to find ones that actually stay on your foot, even other national brands, and I just became content wearing my sneakers without socks. They ALWAYS slid down into my show & I ended up walking on a wad of sock until I could fix it...or usually just took them off after a couple of tries. Enter Under Armor!!! They a mid weight, but not very thick & still breathable. They work too by actually staying on your foot! Not once have they slid down into my show!! Very comfortable but they could be a little more affordable.

Love!
Size: Large, Color: (100) White / White / Mod Gray
Ive tried so many no show socks but I love these. This is the 3rd set I've bought. They never slip off and the material is thin and breathable. Perfect for working out.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.

Great socks!
Size: Medium, Color: (252) Blush Beige / White / Castlerock
Love these socks so much I got a second package. I like how thin and airy they are and they never slide down my heel. For thin socks they’re pretty durable.
