DragRace Concepts Maxim No Prep RC Drag Race Kit

The DragRace Concepts Drag Pak Maxim raises the bar for radio control drag racing. Until now, all other no prep drag car chassis' have been recycled short course truck conversions. The DRC Maxim has been engineered from the ground up to provide racers with a competition level platform. No adaptations. No conversion kits. Just pure engineering and a desire to create the ultimate race car chassis for no prep drag racing. 


The first area addressed was the chassis. The Maxim chassis features an integrated flex control system that allows the racer to fine tune chassis flex to suit the traction conditions of the surface. The flex control is achieved by first tying the entire chassis together starting at the transmission inserts. These inserts are connected to the chassis rails that carry forward to the front end. Racers can adjust flex throughout the chassis by adding or eliminating hardware and links to the chassis rails for an infinite range of adjustment. The chassis offers multiple options for battery placement to tune weight bias, while keeping weight low and allowing plenty of room for electronics placement.

The included Drag Pak Transmission is already proven. The super smooth transmission is strong, durable and capable of handling low turn motors. The transmission features a stand-up configuration to provide more rear weight bias than a lay down setup to provide increased traction, while at the same time keeping the chassis balance more inline. A full set of 7075 T6 hard-coated aluminum gears and slipper eliminator are used to keep rotating mass to a minimum, while the gear differential is a hybrid design that uses DRC hardened internal gears. Combine this with DRC heat-treated steel CVDs and you have a premium level drivetrain that can handle the abuse of outlaw class racing.

Special attention was paid to the front-end. The Maxim features DRC's swept back injection molded front a-arms. Compared to typical "dirt" style front a-arms, these arms provide more forward weight bias in front of the front axle centerline. This means less weight is required in the front of the car to help keep the front end planted. Additionally, the front bulkhead features 1.5 degree removable castor mounts, and the low-profile front shock tower is matched to the included Custom Works MDX "Long" Shocks, allowing for an aggressive body stance. The front castor blocks, bearing carriers and rear hubs are all CNC machined aluminum to help create a platform that offers premium level equipment out of the box.

The injection molded rear a-arms eliminate flex and keep weight low. These a-arms feature 2 degrees of built-in toe in with universal mounting positions on both sides for the shock and anti-roll bar set ups. The rear shock tower is a low-profile design that is matched perfectly to the included, Custom Works MDX "Long" Shocks. Compared to standard SCT shocks, the smaller bore shocks eliminate approximately 2 ounces of weight from the chassis without sacrificing performance. Plus, the kit includes the super popular DRC 10" Slider wheelie bar to provide a wide range of adjustment and proven drag car performance.

All of these features and details combined create the ultimate setup for both no prep and eliminator class racing. Don't get caught sleeping at the tree and grab a DragRace Concepts Maxim to improve your chances of taking the win light when you cross the stripe!

DragRace Concepts Drag Pak Maxim No Prep 1/10 Drag Race Chassis Kit
First off, if you cannot build a car without any instructions, do not buy this. Just hit the back button right now and go look at dr10's. As of now you only have 2 pictures to look at on their website and they're not good pictures. Got to guess on holes and angles from perspective for initial set up. It was enough for me to build it with out issues but I do this on the daily. I'm sure this will be addressed shortly. Shocks, diff, and initial settings have diagrams included. There is no bell crank, so stop looking for it when you open the first set of instructions. Just skip that and go to the build pictures.

Front shocks want 100wt and 8lb springs. Rears want 80wt and 6lb springs. Diff wants 200k low traction, 300k medium, 500k high grip. 3.0t 90/17, 3.5t 90/18, 4.0t 90/19. These are the initial they recommend. 3 screw setup for the slipper eliminator that comes with it. My kimbroughs, X-ray, and xotek spurs fit no issue. I went with 6lb fronts w/80wt and 5lb backs w/70wt based off of some forums I've read. Your call on that. Was no initial specs posted when I bought everything for it.

Will need the typical black grease and thread locker. Some screws are metric, some standard. 1.5mm, 2mm, 2.5mm. .05" and 1/16"

Will need a servo no taller than a protek 160 or reefs 299lp. You won't need a servo horn either. It comes with a dual that the shafts hook directly too it and 3 adapters for the tooth count. No way to get away from the setup it comes with.

Will accept side body mounts and the +hp rear tires, just need to trim the shock tower a 1/4". I took the 5.5mm middle chassis nuts off, added a .75 shim, then screwed the side body mount on that. I'm running baad racing bead locks, they are the standard width. The PL + rims will fit as well. I do know the + tires on these bead locks sit really damn nice. Flush on the outside, little pudge on the inside. I did not use the through body mounts. I used 2 sets of gorilla magnetic front mounts, for front and back, they fit right on the posts and are easy to adjust for height. Both the posts and mag mounts have plenty of adjustment. Then I run my side mounts upside down on the body. Pain in the butt sometimes, but I hate exposed posts.

What I didn't like about the kit. The mix and match screws, some being wallowed out already (accessories screws, not the pre built chassis ones) ) Had a grub pin locked into one of my cups (where it accepts the shaft) that took a strong minute to get out. Had a drive cup to tight to accept the dog bone, had to file the cup. Front bearings were destroyed in one of the front hubs. The rod ball ends for the lower shock mounts are trash (x4). Can't get any size to hook firmly in the hex head. They are 4.3mm balls. I put some Reve d spm's on them, part number RT-006m, don't think amain carries that brand. 4.8mm will work but its tight. 4.5's will work also. 8mm long may work, I had 6mm on hand

I ended up changing out every screw that was in a bag (chassis is 85% built). Screws it is built with had no issues or thread locker. The bagged screws sometimes would grab enough to go in, but insta strip to come out. No good at the track. Not all the bagged screws were junk, think I came across 10-12 of them. So I just changed them all.

All in all the main chassis and parts are top notch. Besides that it looks like they cut some corners on fasteners to get it out the door. Not a deal breaker by any means. It's built but not tested, so I can't comment on the performance yet. I know they were trying to get them out the door for Christmas, so quality control should improve in the following months.

No parts or hardware was missing. All tolerances were great on the machined parts, carbon and plastic. Had to add one .15 shim to a front a arm on the hub, that was it. Probably the best fitting kit I've built. No slop or travel to speak of besides that front a arm and I'm sure it wasn't needed. I just like everything to be perfect.

If you like to dink around and spend some time experimenting, trouble shooting, and having no written instructions this is a awesome kit.

If you're in a hurry to pop this one out, wait. You will only get mad and miss out on a beautiful chassis.

Very nice kit overall, I enjoyed the challenge that came with it. I will not hesitate to buy another when its time for my 13.5 setup.

If you find a aluminum nub and screw in the box don't worry, its just one of the fan mounts (2 of them) on the top backside front of the motor plate. Yes it comes with a fan and spur too.

DragRace Concepts Drag Pak Maxim No Prep 1/10 Drag Race Chassis Kit
This is my first kit build in many years and my first NPRC. Instructions are minimal and at first, I was concerned. But if you have kit experience or mechanical skills, this kit nearly builds itself. And you will not get tolerances this tight with a mass boxed production car. I love it. I can't wait to hit the street with it. If you are new to RC, don't be afraid to ask for help to build this. It's not a Lego set. But the end result is a purpose design rip machine. Glad I went this route instead of buying an RTR then upgrading everything on it.

DragRace Concepts Drag Pak Maxim No Prep 1/10 Drag Race Chassis Kit
So a customer gives a product that they don’t even have yet a 1 star review because the shipping is taking too long? So basically you’re giving the kit a poor rating for no reason. This is why I always read reviews rather than go based upon the overall star rating. Too many people give bad reviews for either something that has nothing to do with the product, because the shipping takes too long, and even because of reasons that had the customer actually read the instructions for the item they would realize they are wrong and their poor review isn’t even correct. The only reason I gave this a 4 star is because DRC has priced it a bit too high in my opinion. I could see 499.99 but 599.99 is a stretch for what you get, or don’t get.

Have no received yet, over 30 days due to shipping method, not happy.

Customer service went above and beyond and sent my another order. I certainly can’t say enough about service with this company. Thank you!

I hate to nitpick the chassis after such great customer service and support, but it’s about making others aware of the issues that I have encountered.

Here is the list of items that I feel is noteworthy to mention:


1. one of the front axles is way out of tolerance, it will not fit through the bearings or the wheel adapter. Attempting to sand it down, but it’s a good quality material.

2. Wheel bearings are low quality and rough sounding.

3. The wheel hex hubs included with my kit are not wide enough (5.5 mm). All the plastic wheels I have from all the major companies require at least a 6.5mm to work on this particular kit. My aluminum bead locks need at least a 7mm to tighten properly. The axle shafts included are really long.

4. The front body mounts in my kit were an inch too short for every Proline and Losi body I have.

5. The rear body mount has one placement , I don’t understand why it does not have other options for placement. It ended up in the worse place possible on the Proline 67 Mustang I’m using for the build.

6. The shocks are complete junk, all 4 leak badly and you can see the front shocks actually bend when compressed due to the severity of the mounting angle.

7. No battery hold down included or even available as an option. You are on your own to make something work with the slots in the battery mounts. I’m blown away by this! Super nice chassis but, it seems like they hurried to get the thing out the door and didn’t finish the detail work.

8. It would be nice to have a mount for the receiver antenna, there is nothing.

9. The steering servo arm looks cheap and there is no option for a better one that I’ve found so far. It is actually so large it contacts both sides of the forward frame support, however it is not enough to effect anything.


Even with all the problems the overall kit is very nice, and I was surprised that was partially assembled when I opened the box. The parts that are not assembled are sections that can be modified or need adjustment by the new owner. It would have been nice to see a shock spring assortment included at this price point, as well as including a slipper clutch option for the top shaft of the transmission. So, those items will have to be ordered separately if you chose to do so. Along with new shocks. Look at spending another $100 or more to finish off the chassis.

I will still give it a 4 star rating due the the chassis, transmission quality and it’s really light, so you can add weight where it’s most suited.
