Cool series for the beginner 1/8 guys to help them upgrade as their skills progress.

I hope this series never end, nice servos ! don't forget to add some after run oil for your engine

This is an awesome set of videos! I just ordered this rtr kyosho and i cant wait to set it up to rip a track! Thanks guys!

Brett, your the best! I love your videos! Fun and informative.

Protek servos are awesome ,I've been abusing the 130ss' for over 2 years in 3 different buggies and still performing perfectly

Love all the videos on this channel but this mini series is my favourite. great for us newer guys in the hobby making the transition from just bashing to also racing. would love to see some other builds in the future? maybe some 10th scale crawlers, buggies, onroad whatever it is love the tips and tricks on how other people set their cars up and where you can save money setting up the car and where you should invest the money great stuff!

Great video.. u inspired me to get back into this hobby after a 10 year hiatus. Thanks.... Bought Losi eight rtr

This series of videos has lit my nitro cravings and landed me back into RC land. My friends and I have dusted off and tuned up two of the backyard tracks. The MP9 TKI4 arrived from aMain and has not disappointed. Cool little project. Dont mind taking the long route as far as upgrades. Had a slight problem with the ride height tabs on the chassis...they flexed as the set screw was wound in.(Difficult to get the + pos. rake cured) Super Bummed. I'll try to develop a cure, if not the HARD chassis will be on its way. Thanks again for your time covering this vehicle and all the other videos you and your team have done.

DYNE 1506 back-plate fits this engine perfectly. Love your vids Dude, Thank you!

Great servo choice, I have the 170sbl's I love them!!! never a problem

Love that servo-walk!!!😂😂😂

Futaba for life lol, good job on the race

Can't wait to see what's upgraded next in part 6

Great video as usual!!! Lookong forward to episode 6

Epic ! I really want one of these buggies

I like the servos you chose, The specs are similar to my JX hv bls7132. They have 454 oz-in and 0.7 sec transit, they were 65 each. Also black aluminum case. Great video bro!

Great Series! Thanks Much!

Removing the pull starter from my RTR was the best thing I ever did, it makes getting the body on so much easier lol

Awesome! You took my servo suggestion! If this wasn’t an Amain/ProTek build, I’d tell ya to put KST servos in. I use them in all my racecars. Check em out, they’re very good!!! I don’t remember if I’ve suggested this yet, but you really should switch ALL of the screws with lightweight titanium screws and switch all the metal shims/washers with aluminum ones, and aluminum nylock nuts as well. Shorten up the wiring too. Extra wire is unnecessary weight, messy, and more likely to cause an issue. A carbon fiber radio tray, carbon fiber shock towers, etc... lightweight titanium turnbuckles/camber links, titanium shock standoffs, lexan wing, lighter weight and better flowing body... all of these things added up shave a lot of weight, resulting in more time between fuel stops, and better overall performance. An engine upgrade will certainly give that mp9rs a boost! It’ll be time to replace all the bearings soon, so upgrade those all at once, not individually. I rebuild all my dirt cars after almost every race. Hope this helps and I’ll see y’all at the track! -E

I expect a least a heat win with those fancy new servos!

It's funny tou said balloons, because that's what I used to use on my shocks. Small balloons. Cheap and easy to get a huge baggie of em!

Now switch the Spektrum out to a Sanwa 😄. Great Vid

Strong servos!

no problem Brett! we all make mistakes, would have been exciting to see whether it really does free up power with the replacement back plate. Ive been waiting for this video too long, dont stop this series!!!!!!!!!!!

Man that's the quickest servo I've seen xD

Holy shit that servo

One thing you might want to change are the shock pistons. The stock ones are really thin, and one of them somehow bent on my car, locking up the suspension. Great video!

Hey Brett, Change the shock pistons to KYOIF347-138 for front and rear. The shock oil should be around 45-ish front and 32.5-ish rear. Also with those servos, I would also run KYOIFW450, it makes the steering more consistent and won't flex compared to the stock plastic one.

More nitro series please and bring back this intro music.

Don’t know if your up to suggestions but my friend had that rtr and I took off the pull start removed the original backplate filled the hole in the backplate wit rtv black permeatex and it ran like a champ works amazing takes 20 minutes.

The backplate for the KE21SP to remove the pull start is Kyosho part# 74031-14

Show. Muito bom 👍🏻

props to CJ

A good upgrade would be to get the TKI3 wc front arms. They have a webbed design like the TKI4 which adds durability. The part number is IF493

I have followed this series since part one, and I want to get an MP9 now. How much have you put into this project?

need to get a bolt kit together im going to buy one this week hate Philips screws

I’m excited for part 6! I imagine thicker shock towers and 17.5 caster blocks are in that buggy’s future. Lastly does Amain carry the hardware that was used for the servos? Thanks!

You could use balloon tubes for shock boots :)

Why didn't you mount the transponder in the place made for it on the radio tray area, then mount the switch next to it? It all fits if done right. Can't wait till you bend a front shock tower (and you will), and see what you replace them both (front and rear) with. Keep up the great videos!

It is true that those high end servos outlast the chassis my Futaba high voltage servo has outlasted 3 chassis so far it’s in its 4th now and still works great

Input! Johnny 5 is alive....

sweet ! those servos are looking good..but i can't afford it..i use savox almost a 100 each

Hi, do you have a tutorial on how to set up the transmitter when installing servos? Cheers and good series!

when you install that backplate you will gain 1000-3000 rpms due to losing the weight of the one way bearing in the pullstart . now the crank can spin faster due to less weight on it

Top name brand using Philip screws? I know its rtr but still

The pull starter on the KE motors doesn't have a one way bearing on the pull start and doesn't drain any power from the motor by having it on there

Put in a racing Engine

Hey Brett loving this series. Great build. Nothing you don’t need and everything to make it run better. Here’s a question for you. I picked up a used Kyosho Inferno Neo 3.0 and it has the KE21SP engine in it. I can’t get it started. I checked glow plug, fuel, air, linkage and carb opening. What is the stock needle settings for this engines carb? I can’t find those specs anywhere. I have the manual but all Kyosho states is the needles are set up from factory for easy break in. I don’t know those settings though. Engine seems to have good pop to it good compression. Mabey my fuel is too old I don’t know. (It’s about a year old never opened 30% nitro). I’d like to get it back to the break in carb settings though

So I’ve bought 170tbl and 170sbl from y’all and neither came with the aluminum servo horn

Are you going to get it ready for another race

Hey Brad, will I be able to use this servo on my Kyosho inferno neo st 3.0?

I run low voltage servos and a life pack in both my nitro cars. Knock on wood I have yet to have a servo burn out or even strip, and swapping cars with team mates they don't notice a difference in my car and I don't notice the high voltage servos in their car.

I hate those shock boots. Wondering if the accordion-style are any better. They should fit as well. (KYOIF346-08).

I started with an rb6.6 rtr and the chassis was of far lesser quality than the kit. Is the chassis on the mp9 rtr same as kit?

Hi guys, I have a question. I'm building a nitro buggy 1/8 scale (losi 8ight 2.0). Does the throttle servo need to be as tough and have the same torque as the steering servo? Also, do all servos work with a non Lipo battery on the car? TIA

The next upgrade should be a backplate :)

How do u know how long the receiver battery will last, to avoid runaways, might be a video on its own.

Dont forget the knuckle bushing screws need loctite

what did you guys do with the car after the series was over?

Should put a new exhaust pipe on the engine. Should liven it up and not have to worry about the pipe popping off the header after a decent hit.

Hi. I want to change the servos for high voltage servos. But I have the transmitter and receiver that comes with the rtr kit. The receiver I think is 4.8 to 6v. Is there another receiver compatible with that transmitter that supports more than 6v or will I have to change both? Thank you.

When will this be back in stock, saw the whole series and I want one already. Lol.

Hey A main. I have this rtr and is there a chassis brace or guards that protect against that chassis scraping?

Great Serie! Keep working. Suggestions make one serie about conversion nitro 1/8 buggy to Electric. And one serie about chassis setup for better results om race.

Are steering servos different to throttle ones? If so how?

Do you really need a servo that is so good on the throttle and brake as the steering? Surely a cheaper servo would be ok on throttle/ brake as it does get half the abuse.

Help I am trying to find a 3mm nut driver for my kyosho mp9 Tki4 Any ideas thanks

I seen guys cut the fingers off of rubber gloves n make shock boots with them

Does Horizon own every rc car/truck/accessory??! I say that in jest, but so many rc brands are Horizon branded

hey dude what shocks do you have on there? the one that came with mine doesnt have what you have on your car?

Why would you put a backplate under the pull start?

Send me those stock servos @Amainhobbies would def need them for my mp9

Are you going to upgrade the shock towers

If that was mine I would put on a chassis protector underneath so no dirt will get in the screws

I love watching you do these. You were having WAY too much fun with the steering servo, walking the car across the table. I had to pause the video for a few seconds, I was laughing so hard.🤣😂 Oh, and I gave you and AMain a shout out in my latest video, something I do not do for companies. Check it out at the end of this video: kzfaq.info/get/bejne/nOCiYJefz7Wuj2w.html You just keep on being you and make me smile.😊😍

wish there's a track to play nitros :( space is premium here

I thought you deserved another👍from our other channel.

Turn table, Lazy Susan. Your thoughts?

Im Johnny number 5 “short circuit”

Dude raise the ride hight. Maybe you won’t break the screws

When are you going to announce the winner to the CRAWLER KING🤴

Hi
