MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 
PURCHASER ACKNOWLEDGES THAT THEY ALONE HAVE DETERMINED 
THAT THE PRODUCT WILL SUITABLY MEET THE REQUIREMENTS OF THE 
PURCHASER’S INTENDED USE.
 Purchaser’s Remedy
Horizon’s sole obligation and purchaser’s sole and exclusive remedy 
shall be that Horizon will, at its option, either (i) service, or (ii) replace, any 
Product determined by Horizon to be defective. Horizon reserves the right 
to inspect any and all Product(s) involved in a warranty claim. Service 
or replacement decisions are at the sole discretion of Horizon. Proof of 
purchase is required for all warranty claims. SERVICE OR REPLACEMENT 
AS PROVIDED UNDER THIS WARRANTY IS THE PURCHASER’S SOLE

Limitation of Liability
HORIZON SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL 
OR CONSEQUENTIAL DAMAGES, LOSS OF PROFITS OR PRODUCTION 
OR COMMERCIAL LOSS IN ANY WAY, REGARDLESS OF WHETHER 
SUCH CLAIM IS BASED IN CONTRACT, WARRANTY, TORT, NEGLIGENCE, 
STRICT LIABILITY OR ANY OTHER THEORY OF LIABILITY, EVEN 
IF HORIZON HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH 
DAMAGES. Further, in no event shall the liability of Horizon exceed the 
individual price of the Product on which liability is asserted. As Horizon 
has no control over use, setup, final assembly, modification or misuse, 
no liability shall be assumed nor accepted for any resulting damage or 
injury. By the act of use, setup or assembly, the user accepts all resulting 
liability. If you as the purchaser or user are not prepared to accept the 
liability associated with the use of the Product, purchaser is advised to 
return the Product immediately in new and unused condition to the place 
of purchase.
Law
These terms are governed by Illinois law (without regard to conflict of 
law principals). This warranty gives you specific legal rights, and you may 
also have other rights which vary from state to state. Horizon reserves 
the right to change or modify this warranty at any time without notice.
WARRANTY SERVICES
Questions, Assistance, and Services
Your local hobby store and/or place of purchase cannot provide warranty 
support or service. Once assembly, setup or use of the Product has been 
started, you must contact your local distributor or Horizon directly. This 
will enable Horizon to better answer your questions and service you in 
the event that you may need any assistance. For questions or assistance, 
please visit our website at www.horizonhobby.com, submit a Product 
Support Inquiry, or call the toll free telephone number referenced in 
the Warranty and Service Contact Information section to speak with a 
Product Support representative.
Inspection or Services
If this Product needs to be inspected or serviced and is compliant in 
the country you live and use the Product in, please use the Horizon 
Online Service Request submission process found on our website or call 
Horizon to obtain a Return Merchandise Authorization (RMA) number. 
Pack the Product securely using a shipping carton. Please note that 
original boxes may be included, but are not designed to withstand the 
rigors of shipping without additional protection. Ship via a carrier that 
provides tracking and insurance for lost or damaged parcels, as Horizon 
is not responsible for merchandise until it arrives and is accepted at our 
facility. An Online Service Request is available at http://www.horizon-
hobby.com/content/service-center_render-service-center. If you do not 
have internet access, please contact Horizon Product Support to obtain 
a RMA number along with instructions for submitting your product for 
service. When calling Horizon, you will be asked to provide your complete 
name, street address, email address and phone number where you can 
be reached during business hours. When sending product into Horizon, 
please include your RMA number, a list of the included items, and a brief 
summary of the problem. A copy of your original sales receipt must be 
included for warranty consideration. Be sure your name, address, and 
RMA number are clearly written on the outside of the shipping carton. 
NOTICE: Do not ship LiPo batteries to Horizon. If you have any 
issue with a LiPo battery, please contact the appropriate Horizon 
Product Support office.
Warranty Requirements 
For Warranty consideration, you must include your original sales 
receipt verifying the proof-of-purchase date. Provided warranty 
conditions have been met, your Product will be serviced or replaced free 
of charge. Service or replacement decisions are at the sole discretion 
of Horizon.
Non-Warranty Service
Should your service not be covered by warranty, service will be complet-
ed and payment will be required without notification or estimate of the 
expense unless the expense exceeds 50% of the retail purchase cost. 
By submitting the item for service you are agreeing to payment of the 
service without notification. Service estimates are available upon request. 
You must include this request with your item submitted for service. Non-
warranty service estimates will be billed a minimum of ½ hour of labor. 
In addition you will be billed for return freight. Horizon accepts money 
orders and cashier’s checks, as well as Visa, MasterCard, American 
Express, and Discover cards. By submitting any item to Horizon for 
service, you are agreeing to Horizon’s Terms and Conditions found on our 
website http://www.horizonhobby.com/content/service-center_render-
service-center.
ATTENTION: Horizon service is limited to Product compliant 
in the country of use and ownership. If received, a non-com-
pliant Product will not be serviced. Further, the sender will be 
responsible for arranging return shipment of the un-serviced 
Product, through a carrier of the sender’s choice and at the 
sender’s expense. Horizon will hold non-compliant Product 
for a period of 60 days from notification, after which it will be 
discarded. 10/15
