OMG that was awesome test. Traxxas should be ashamed putting that in our cars.

[gingersnap]

Dude i love how ypu scientifically test stuff man its awsome

[jamesstubbs]

Power HD is the best bang for your buck out of all those servos which is why you were surprised. I have two Power HD DW-25LV in my E Revo 2 and while they were just 10 bucks cheaper than the Savox 1256TG's I was going to purchase they have way more torque and faster response time than the Savox servos.

Love Your Tests, good Work, That helps a lot of people, thank you

[monchitoscalecrawling]

A hobbywing 1080wp esc has a internal Bec with enough voltage for a savox 1230. Love your videos, specially the tire test ones. Keep up the good work

i put the Power HD 23kg in my TRX-4 and it works like a dream, its been through hell and it still works like its brand new. definetly a great servo for the TRX-4 if you dont want to spend a fortune.

Great comparison vid! That 959 is a beast!

[edwardcorbett]

Excellent test and video! Based on this (pretty much on its own) I chose the power hd 20 (instead of savox or cys) as my “budget” first upgrade for the useless and rapidly dying servo on my FTX mauler... I’m super impressed with it! The test was not necessarily “comprehensive” with only one of each servo, but definitely fair! Who is going to buy a whole box of each servo and run them regularly? We buy a few different servos maybe, like this test, and we learn from the company’s first effort.

I've been impressed with my powerHD 20kg servos. I have one in a 4x4 stampede and one in a Brushless Savage and it does fantastic in both rigs!

[MrSUBY]

Great comparison between the servos. This was very informative.

[wereallydontknowwhatweredo]

That servo test rules! I lost another bet too. Keep up these comparison tests, I have to win at some point! Oh yeah, awesome video too!

[johnclc_]

I have the power hd 20kg servo for my scx10 and its very strong and u cant beat the price!!!!

[montesamapping]

Really interesting, fast and direct information !!

[GeneralHobbies]

excellent test. i wish you had more servos

[joshwalker]

Great job on the test. Great setup. The factories should start sending them to you as they get updated ones that they want to prove and showoff.

[kingstonrc]

Dude that is awesome man, great job 👍🏻super cool 😎. Great test!!!!

[Darkcruzer]

very helpful! had a hexfly die on me and was looking at the power hd 20 looks like its a great upgrade!

[johnbeck]

I nominate this to be the best video of 2020, no frills; just fact! bravo,

[noeysfastrc]

Nice test revealing the strength of the servos no one has done before. Appreciate you sharing your video 👍

[RobKingRC]

This was a fun test, like to see an updated version.
