Cobra tranny
I'm anxiously awaiting some response to this question on the the trans problem.
I was told 'not to oil 1-way' but I shelved my Serpent GT for the same problem listed by Tshabala. I only had close to half a gallon through engine in that car (engine had been successfully used in another car previously). I only heard it shift about 8 times and the rest of the time it did what Tshabala's car does. If the shaft 'wears-out' before it can 'breakin', Cobra can stay on the shelf.

Page 5 of the assembly manual says nothing about needing to lube bearing, 'one-way lube' is not listed in the fluids needed section on page 3.
I've never lubed the one-way in my Kyosho.........because I was told not to. My first 'one-way' failure was after over 3 years of race use. My second 'one-way' failure seems to be an 'out-of-box' problem with the Serpent. So, someone please clear up the issue for Tshabalala and I.
KR145.........if Serpent ships a 'one-way' bearing dry and provides no lube instructions if needed, I see it as a Serpent problem........because I was 'assured' I 'couldn't go wrong buying the Cobra GT'. I watched the local TeamC owners go through that and I just shook my head in disbelief that this car acted just like their 'one-way' failures.

Version 2 look like 'free-floating-stars' as opposed to Version 1 that look like they have a 'washer' on the larger end of the spiders. The 'washers' were eliminated on the inside of the diff case at the spider assembly.

I have been having problems with my 2 speed transmission on my serpent gt. Every time i give it gas specially when i lean the engine to get more RPMs it suddenly sounds like one of the gears goes out then i push the break and it engages again. I have replaced the one way bearing and went with larger gears and it keeps doing the same thing. Has anyone had that problem and how could i fix it. Thank you.

While we're on this subject, I recently had to replace the 2 speed housing. Since then it seems to me like it is stuck in 2nd gear. No shifting, sluggish off the line then about mid rpm it gets going well...but never a shift. If the one way went bad, it wouldn't shift to 2nd right? Pretty sure mine is in 2nd from launch.
Things I have done to TRY to help.
1. Replace 2 Speed housing.
2. Replace 2 speed shaft
3. Replace shoes with new shoe kit, to include springs, shoes etc...
4. Adjust screw to 5.5 turns out from bottom.
5. Make sure set screws in middle of shoe were not interfering, nor pushing the shoe out.
What else can I try?
