Hypoxic 812 Posted February 17 I watch videos of the Lunchbox taking flight, rolling, flipping, smashing into things. I slightly clip a power pole and bust a servo saver. What gives?

Guest Posted February 17 I broke 3 bashing mine in the garden, then broke the servo mount on the chassis a few days later. I got an aluminium servo horn from ebay and then installed the UK monsters alloy servo mount brace. It's a lot tougher now with those two relatively cheap modifications.

MadAnt 856 Posted February 17 Just have to find a good aftermarket heavy duty servo saver, there should be plenty to choose from. 2 Share this post Link to post Share on other sites
Hypoxic 812 Posted February 17 I’ve been running the Tamiya 51000. 1 Share this post Link to post Share on other sites
Twinfan 2452 Posted February 18 I broke a 51000 that I'd originally fitted on my basher Lunch Box (I fit them to almost everything) so decided to use all the spare standard servo savers I haven't used from other kits instead to use them up. Haven't broken any yet, the original standard saver has been fine! Share this post Link to post Share on other sites
Hypoxic 812 Posted February 18 I need to put some bumpers on that power pole. I believe that’s how I broke the last one as well. edit: After changing out the servo saver I was making sure the horn was center and realised that the throw was pretty extreme, enough to cause a lot of binding. I played with the servo endpoints until the control arms just almost touch the A-arms. Maybe taking out all of that stress like that will help my cause.

dannymulder 1125 Posted February 18 I run and bash my lunchbox very hard with an castle 5700 kv motor in it , I never broke any servo saver, to be honest I never broke any servo saver on my cars. Maybe what you said, you had your end points not adjusted, maybe that is wat breaks the servo savers.s Share this post Link to post Share on other sites

Not sure maybe other Tamiya heads can chirp in. You can always get the large servo saver and trim it down to fit. Also assuming you are using a metal gear servo, because the heavy duty servo saver will strip plastic servo gears. 1 Share this post Link to post Share on other sites

Definitely a good idea to use a metal gear servo with anything that uses oversized tires. Share this post Link to post Share on other sites
Hypoxic 812 Posted February 18 Yep, using a metal gear servo. Share this post Link to post Share on other sites
Kowalski86 4983 Posted February 18 Either a Tamiya High Torque servo saver or a Kimbrough would be a good upgrade. I learned from my experience with a Stampede, that RCs with big wheels and no bellcrank put a lot of stress on servo savers. Share this post Link to post Share on other sites
