bholio 0 Posted October 17, 2004 I've been working on my Wild Willy (mk2) on and off for a month or 2. I finally got the chassis built, the radio gear installed, and a good-working motor. When I got the car, part J1 (servo saver) was broken. I found a NIB J parts tree, problem solved. This evening, I was driving it, and crashed. Broke the same part again. Is this a weak point? Or did I just get lucky? The servo saver spring was not cranked super-tight. Anyone have a solution? I don't really want to go and replace J1 with a new one again, just to have it break again. My plan is to CA it back together, then reinforce with fiberglass. Share this post Link to post Share on other sites
DJTheo 2 Posted October 18, 2004 Did you lubricate it? Some greases attack plastic... Better buy a 3rd company or Tamiya high torque servo saver. Cheers Share this post Link to post Share on other sites
jozza 1 Posted October 18, 2004 On my Monster Beetle, Midnight Pumpkin and WWII, I have replaced the kit servo savers with generic ones from the LHS, as I found they kept breaking. So far (touch wood), none of the replacement ones has broken. I have also used CA and fibreglass tape with success as a temporary repair on the Monster Beetle servo saver, it was a good repair as it still wasn't broken when I swapped the kit servo saver for a Trickbits one.

Shodog 1835 Posted October 18, 2004 Keep in mind that the plastic even if new is still probably 20 years old. This makes for some brittle plastic. I would say buy a new piece then reinforced it with some fiberglass cloth and some epoxy On my runner I keep the spring pretty loose so you get a lot of action out of the servo saver.

bholio 0 Posted October 18, 2004 Thanks for the replies. I guess this is not a common problem in the WW1, from the lack of 'me too' posts. The plastic didn't *feel* brittle. No lube. I rarely put lubrication of any sort on my cars, even in the gearboxes. I think I just got lucky. It looks like a good shot the the front wheels can pull that J1 part beyond where it can move, and tear it in half. Maybe mine is not assembled correctly. The cars has lots of modifications from the previous owner. I might have missed something while rebuilding it. And to think, I let the car crash into the house to prevent it from tipping and scratching the beat-up not-yet-painted body. Thats the most frustrating part. I'll fiberglass it, unless I can come up with a way to put a normal servo saver on it. Share this post Link to post Share on other sites
bholio 0 Posted October 21, 2004 Well I fixed it by merging half of the broken J1 part to half of a tamiya servo saver. Seems solid enough. You can't just use a standard aftermarket servo saver. The WW1 saver is special to that chassis. Share this post Link to post Share on other sites
DJTheo 2 Posted October 22, 2004 Yes, I wrote about aftermarket one as I thought in the beginning that mk2 was reffering to WW2, later I realized that it was reffering to the long wheelbase model. Cheers Share this post Link to post Share on other sites
jozza 1 Posted October 22, 2004 I thought that too. Ah well, sounds like you've got a working solution now bholio, so it came out fine in the end [^] Share this post Link to post Share on other sites
simensays 321 Posted March 16, 2021 Ah, the problems of yesteryear 3D printing these small, hard to find parts has def made things easier - no fiberglass needed! Share this post Link to post Share on other sites
