Kagama Thread 'Lee Spring Servo Saver Spring - What you need to know'

I've started this thread to make it easier to find all the info in one place.

It all started here with DaniC's post - how to adjust servo saver:
https://www.corallyforum.com/threads/easiest-way-to-adjust-servo-saver.459/

Back in the day, around 2022, Danny and myself measured up our springs and looked for spring manufacturers that can make bespoke springs.

Lee Spring were selected as the manufacturer of choice. Primarily because they make the right spring, but also because they have global reach.

Speccing a simple compression spring is more technical than people realise...

Does anyone know where I can get a stiffer servo saver spring for my kagama 6s. The stock spring is to weak.

It's always amazed me how weak the servo saver springs are on rigs - and it's not limited to the modern RTR stuff either. It's an age old thing. The Savage had a terrible servo saver. It literally gave zero steering and had to be swapped out with a different truck's steering - the monster pirate.

It's generally less of an issue on 1/8th race Buggies and Truggies which seem to have proper, pre-loadable springs from the get go.

Somebody mentioned that thumb nuts on servo savers always back off - but in the 40 or so rigs I've owned over the years, I've never had this happen to me. I just don't see how a thumb nut preloading a spring can get loose.

This is like saying your shock absorber preload screws need threadlock. It's utter fallacy.

The Lee Spring works, the spec is right - if anything I would understand it if people wanted a slightly lower rate on the spring because it really doesn't take any prisoners! 😝

That being said, my servo survived following my 50mph impact with a kerb during a speed run in the rain using the Lee Spring. It would have been a very different story with a clamped down stock spring with no space between the coils. 👍

Full opposite lock. 50 mph + and sideways into a kerb 😱😬. Ouch.

Result? A scuffed wheel. The video of it is on my channel.

I don’t even have the Lee spring turned up at all probably at its lightest setting, again I’m new but have raced flown for years so I know what feels good what doesn’t. What’s your channel BTW sorry with my meds from my accident memory is very limited. Eye socket crushed eye damage all from being a nice person and unfortunately got kicked my there horse

Yeah, horses are no f@#£&#g joke. Copy that. That's a very nasty head injury and I do hope things fully improve over time.

Here's my channel buddy.

Can’t tell ya how many surgeons specialists etc I’ve seen in the last 18months but I’m still 8 above. Way I look at it could be a lot worse and bad feelings towards the horse she was defending herself from my gelding who for whatever reason didn’t like her. I just had a unfortunate accident stuff happens
