principals).  This warranty gives you specific legal rights, and you may also have other

this warranty at any time without notice.

WARRANTY SERVICES

Questions, Assistance, and Services—

Your local hobby store and/or place of pur-

chase 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

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 respon-

sible for merchandise until it arrives and is accepted at our facility. An Online Service

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 replace-

ment decisions are at the sole discretion of Horizon.

will be completed 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

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

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.
