Important Disclaimer about our 17" Parachute model:
The 17" chute is our base/entry-level model and is made of a lower quality nylon mesh material and does not have strings like the parachute shown in the lead picture. See 2nd picture for what the 17" chute looks like when deployed. Rather than strings it has a ~10" long cone-shaped net material that leads down to a ~6" string with a small loop at the end. This loop can be attached to the car (optimal placement is on the rear trunk lid/under the wing) or used in conjunction with a piece of string for a further lead off of the car. The 17" barrel & related components are the same as the 24" version so it can always be upgraded to the premier 24" chute down the road.


AJCMods 3D Printed Fully Functional RC Parachute Kit for 1/10-1/5 RC Drag Cars & Speed Run Cars! After weeks of testing and prototyping we are proud to introduce our spring loaded, servo actuated, full function parachute kit in 6 different configurations to suit your ride. This parachute kit helps slow down your RC at the end of a high speed run. Designed to be used in conjunction with normal ESC/Motor braking and operates from a 3rd Channel TX/RX(NOT the stock 2 channel equipment). Conventional electronic braking heats up the motor quickly and can cause the car to become unstable and spin out - this parachute kit improves braking stability and helps slow down the car by introducing wind drag, and LOOKS GREAT doing it. A properly packed parachute will fully deploy in 0.5 seconds or less at speed as it is shot out from the spring loaded barrel and instantly starts to unravel and deploy. This parachute "barrel" is designed to mount on the rear of the body, and the actual parachute attachment varies depending on setup (see below)


Read Before Use:

Attaching The Parachute

Where you mount the parachute will vary depending on the make and model of your car, the add-ons, center of gravity, weight, body type, and track conditions. A general rule of thumb is you want the parachute line to be on the same level as the top of your tires when the parachute is pulled outward parallel to the ground. On the DR10 for example, this line is achieved by mounting the parachute just below the rear wing, using the center wing bolt and a zip tie as a securement point. Use the provided carabiners, clips, zip ties, and/or keychain ring to fine tune your mounting point.

High Speed Deployments:

Modifications to the 24" or 30" parachutes are suggested for rigs trapping at 55+ MPH

 We suggest cutting corners out of the chute and/or cutting a hole in the center of the chute as shown: 

Important info on the Parachute Choke

Adjusting the choke is very important! Use the provided red or black shrink wrap as the choke. The choke needs to be adjusted based on how you want the parachute to function; if you want to use the chute on nearly every run as an aid to slowing down, bring the choke along the strings to nearly the end of the parachute, leaving just 3-4" of string exposed before the parachute begins. This will allow the parachute to open more gradually resulting in a smoother transition of force to the car and more stable deceleration. For faster trap speeds simply bring the choke higher and higher, up to just 1" of exposed string before the parachute. If you want to use the parachute for emergency situations only, to avoid hitting obstacles such as a wall or a parked car, adjust the choke to about half way up the string - this will make the parachute deploy quicker and will stop the car faster, but may lead to a rollover or abrupt/disrupted stop.

NOTE: This kit is designed to work with 3 or more channel transmitters as a 3rd channel switch is needed to activate the servo, this means the stock DR10 transmitter and any other cheap 2-channel transmitters WILL NOT work with this parachute kit. We can bundle these with a FlySky GT3B Transmitter & Receiver for $50 extra.
