Darn it…Typhon Grom blx servo saver split

[PaPa K]

First battery pack, running at 50% and I loose steering. Pull a 180 in the snow to come back to me, wheels return to straight, and no more. Investigation reveals a split servo saver arm. Looks like Arrma will send me a warranty replacement, but I feel an upgrade may be a good idea. There was no contact or wrecks so why put another weak link in? Thoughts from you folks? @Doom! @Tunedfrog @Greywolf74 and others?

I've always went with, "if it isn't broke then don't fix it" but if something does break, I always go with an upgrade.
As far as your Arrma, I couldn't tell ya what upgrade are available.
I only have the old Mega version of the Typhon so not sure if it is the same as the Grom series or not, nor do I remember if I've replaced it or not.
If Arrma sends you the part then I would put it aside and install an upgrade.

That was my thinking, keep the replacement for an extra. So far the only upgrades I am seeing are aluminum, but that should be ok if it is properly adjusted.

 

[Tunedfrog]

Keep one thing in mind if you go with aluminum, it looks nice for sure but
it adds weight so it slows down the rig and after a bad crash, aluminum bends and doesn't
return to it's original shape, plastic does.
I recommend using RPM RC

This is strictly my opinion...I own a Granite and Mojave Grom, and the Losi Nascar (which is still the Grom platform), and I seriously don't think servo savers are necessary on such a small/light car. If you are still convinced that you want to run a servo saver, Hot Racing makes an aluminum upgrade that is a direct fit. Also, and just my opinion, I think the stock servo is lacking, so I run aftermarket servos (with metal gears) and no servo saver. The steering is much more precise and I have not run into any issues with blowing out the servo gears.
As an aside, I still have 2 stock Grom servos with servo savers if you want them. Just PM me your address and they are yours (my dime)

Great offer @MB401 , but I was thinking of a solution like yours. Do you remember what servo and arm you used? If it has to come apart I like to do it right. Also have to see if I can pull the pan skid to get to the esc platform screws….

The NSDRC RS100 is a killer micro servo. Highly recommend. Just keep in mind that it has a 25T output shaft - I buy the servo horns directly from NSDRC but I’m sure you can find them elsewhere.

@PaPa K
Couple of photos of the NASCAR setup for reference (I have the exact same setup on the Mojave and Granite). Here is the servo horn I use: https://nsdrcscaleparts.com/collections/servo-horns/products/losi-mini-b-t-aluminum-servo-horn

Only down side to NSDRC servos is that they are a bit pricey, but you get what you pay for.

Nicely done @MB401 Have an upgrade servo saver coming to get her back on the road. However, I have bookmarked the info you sent and will get a strong servo and arm in the parts stash. Even with a new upgrade saver on it will only be a matter of time before the original servo takes a holiday
Thanks again for the info.

@MB401 Did you use the recommended mini bec or is it working ok straight up? I have all stock electronics at this point. Thx.

 

[MB401]

I don't run stock electronics in my Groms but I also don't use an external BEC either - without any issues

@MB401 wanted to let you know that the rs100 and arm are working great in the Typhon. I recently got a Mojave blx and already have another servo and arm in the parts stash. As a side note, took 5-6 weeks to get a replacement saver under warranty, glad I did not wait. Thanks again.
