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.

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

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

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.

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.

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
