Re: Anyone tried this? Yellowed parts white

I think the parts will be fine. Here is a paper on the tensile strength of nylon sutures after exposure to 3% hydrogen peroxide: http://www.utsouthwestern.edu/utsw/cda/dept28151/files/338868.html Per table 3, there was a slight reduction in the tensile strength, but it was not statistically signific...

Re: Buggy ID... from memory

How about a Kyosho Cactus? It doesn't have the pinion + spur arrangement you described, but it does have the other features and a very odd gearbox :D . The grooved tires front and rear were stock.

Re: So who also collects Lego?

That Mustang is a fantastic set. It's on my list too; hopefully by the end of the year.

Lego sets are like potato chips...and vintage RC...you just can't have a few! :lol:

Re: 3d Printed Body Molds

I don't know exactly what the pros use, but here's my materials experience in vacuum forming... Thermo/vacuum forming requires a rigid, tough material with a low coefficient of thermal expansion, as well as the ability to withstand cyclical 400F+ temperatures. As polycarbonate cools and shrinks, it ...

Re: New Optima-based Build

Made some more progress today. Got the steering servo in, battery mounts installed and an additional chassis stiffener behind the spur gear. At this pace, I may actually get to test run it (sans body) this weekend! :shock:

Re: New Optima-based Build

First video running in the backyard with the body, brushed Slot Machine stock motor and 2S Lipo battery. KVDNHFPf8HI And the first casualty from that flip: Casualty.jpg Time to redesign and re-print! The front and rear shock towers are bent a bit too; I will probably leave the aluminum in the rear, ...

Re: [completed] And now something completely different: YR4-M2 Type-J

I really like this build/restoration. Fantastic!! And, as someone else mentioned, such an informative write-up. My knowledge of Yokomos starts and ends with the 834B, so it's great to learn new things and see the evolution from the YZ-10. Thanks for all the detail!!

Re: So what did you get in the post today ???

I'm excited about this car...and parts...and spare oem body. I think it will be a shelf queen, which is not something I usually do, but then I won't feel bad about occasionally running my other one. :D

15" of Snow in Central PA = Blizzard Time!

It's rare to have this much snow in December in Pennsylvania, so my son and I put it to good use! :D

Re: 15" of Snow in Central PA = Blizzard Time!

Glad to see you were able to enjoy it. The Blizzard drove like it was floating on a cloud. :) I had to clear snow for nearly 7 hours with no breaks, and am still really sore. :? Wow...that's a lot; quite a workout! Get a Kyosho Blizzard. It comes with a plow attachment; makes cleanup much easier! :...

Rears came today. I've had the fronts for almost 10 years. I can finally fully restore my no-stamp Edinger. Happy day!!
