The problem with Spektrum is if you contact them, you're not contacting them. You're contacting Horizon. If you look at a lot of the Spektrum servos, you will notice they don't show you specs you need to know before buying a servo. But if you contact "Spektrum" asking about these specs, you will likely get a response like I did - "The manufacturer doesn't give us those specifications". Word for word, I kid you not. Which basically is like them saying - "we just buy stuff from China and slap our name on it". That was not the case back when it was actually Spektrum. For a hobby shop to grow so big that it has a major control of this industry, and our hobby, and hss no clue whst they are selling is in my opinion - disgusting.
That's like a gas station growing so powerful it now controls the quality and price of the gas we buy, our groceries, health products, candy bars, etc. And you can't buy gas without it coming with a gallon of milk that tastes like it came from a horse, a 32 count pack of toilet paper made from strips of newspaper, which you are now forced to take home and burn because your garage is full of rolls, and a two year old Snickers bar, who they forced out of business and purchased to monopolize the candy industry 5 years prior. And when you ask them the ingredients in the Snickers bar, they say "The manufacturer doesn't give us that information".
You're too young to know just what the big corporations have done to this world kiddo. This hobby used to be sooo different. Your opinion is based on what you know, but us old farts have our opinion because we know how much this hobby has been controlled and ruined by the conglomerates. Greedy people that have done everything they can to take control of every aspect of our hobby, just to make a profit off selling us crap they buy from whoever will make it the chespest.
The world was a better place before automated call answering and call centers!
Years ago, when you had a problem with a product, you could call the company, have an actual conversation about the issue and have some plan of resolve nailed down in 10 mins. You MIGHT even speak with the owner or manager of the company! Someone who makes more than min wage. Someone who's invested in the company who might actually give a crap about customer satisfaction and the company name.
Call Horizon customer service and ask to speak with a manager... let me know how that goes.
I don't expect someone who has always had google in their lives to understand this but google and other mega corps have destroyed a lot of what made America great imo.
There were sh!tty companies all over the planet but in the US, we had pride in our products and cared that the customer would WANT to come back and not being FORCED to buy their subpar, mostly imported junk because wrinkled tariff men found a way to deter competition in OUR country.
Only Horizon can import Chinese junk... the rest of us have to pay extra.
Years ago, I bought a Tekin esc. It was a VERY nice esc and to a young man it was VERY EXPENSIVE!!!
I promtly put a set of Hot Trick heat sinks and set the esc on fire. WOW!!! So VERY sad!!!
I contacted Tekin and they told me to send it in.
They fixed it for free and told me flat out not to use the sinks any more because that IS what fried the esc.
They KNEW I fried the esc, my fault entirely, and fixed it for free anyways!!!!
THAT is customer service! THAT is what keeping a customer is about!!!
I bought a number of Tekin products since and have a couple vintage units that still work great today.
Spektrum and a lot of other companies today have NO interest in seeing their products 'last'.
Their business model is to produce the cheapest gear possible with a set failure date that REQUIRES you to buy more and more product.
The spektrum electronucs loaded into rtr cars opens the door to otherwise uninterested buyers. More like FORCES the door open.
If someone said to me, do you want a spektrum radio or a Futaba... I'm gonna pick Futaba EVERY time.
Since its going to take a noob a week of stressful bench time to replace a 'whole radio system'

many get intimidated and buy a Spektrum replacement/'upgrade' rather than a hexdriver and a good quality radio.
Horizon is preying on noobs is the best way I can explain it.
Then, once a person gets a collection of 5 or 6 cars, the reality of changing ALL those receivers over, the labor and expense... another easy-in for Spektrum.
As far as I can tell, for my needs, the NB4+ was easily the best radio for the money. Until proven otherwise, I'm gonna run with it.
If ever I need upgrades from NB4, Sanwa or Futaba is where I'll look. Spektrum simply isn't an option.
I wonder if one day these sh!t companies will understand that they can still make money without destroying everything good while they profit.
