Service, Parts and Discontinued Products

I want to purchase replacement parts for one of your products. How do I do that?

You can purchase each and every individual item that was packaged in your kit. Please use the parts list provided with your model to assist you in determining the exact items you need to order or you may click here to go to our parts pages to assist you.. Please contact your favorite Great Planes dealer to special order these parts for you, which may provide you some savings from full retail pricing as well as shipping. Alternatively, you can purchase replacement parts directly from us, by simply providing us your mailing address and the stock # of the item you require, as well as a method of payment. You can fax or mail us with a credit card # (Visa/MasterCard) or mail a check. FAX 217-398-7721; mail: PO Box 788, Urbana IL 61801.

I would like to purchase a copy of the manual for my (insert discontinued model here). My dealer has already confirmed you have no more in stock. Is there any way you can help me?

If we no longer stock your manual BUT we still have a file copy, we do offer you a way to replace this vital tool. We can have our office copy of a manual photocopied at a charge of:

Manual: $10 plus $5.50 shipping (US) or $13.50 shipping (international).
(Note: Items need to be sent out for copying so please allow 4-6 weeks for us to fill requests. Unfortunately, we cannot scan, email or fax these items.)

Please fax us at 217-398-7721 the information requested below including credit card information for payment (Visa/MasterCard), or mail us a check to:

Hobby Services
3002 N. Apollo Drive, Suite #1
Champaign IL 61822

Unfortunately, we are unable to send out via open account (with an invoice) due to our computer system set up.

PLEASE NOTE: We require the following information:

  1. The name of the specific kit (ie. AirCore 40 Trainer) (as much info as you have if you are not sure of the exact name);
  2. Your mailing information;
  3. Your payment information; and
  4. Your return email address and at least one other means of daytime contact (phone, fax, alternative email) to provide you confirmation of your order.

Please note that copied manuals cannot be returned or refunded. If you are unsure the name/make/model # of your kit, please ask for help from fellow modelers to be sure your purchase is correct. Please be sure you provide us the kit # or full kit name when we take an order to copy your manual or plans, as we cannot refund the cost if what you receive is incorrect.


Can you please email me the plans for your (insert ARF name here) model?

Unfortunately, ARF models are not built over plans like those used by a single modeler to build a model kit. Therefore, we do not have any type of plans to provide you for rebuilding your ARF model. However, wing sets, tail sets, fuselage sets, and other parts are available for nearly all of our ARF models for purchase through your favorite hobby shop.


Why did you discontinue a certain kit? Was there something wrong with it? Will you ever produce more? How can I get one, if my dealer says he has no more in stock?

Unfortunately, there comes a time in every kit's life where it is no longer produced. In many cases it is simply not economically feasible to produce an entire run of the model. In some, the kit has been succeeded by a newer model. Lastly, sometimes molds, dies or other parts are no longer usable. At any of these points, the kit is discontinued. Occasionally, due to popular demand, we may do a limited production run, or even re-engineer and reproduce a former kit. However, there is no way of knowing if that may occur with the model you have requested.


I would like to purchase a copy of the manual for my (insert model here). My dealer has already confirmed this is not a regular stocked item. Is there any way you can help me?

We are currently stocking manuals and parts for many discontinued models, as we do for all our models for several years after their discontinuation, until our parts stock is depleted. At that point, those items are no longer available either.

As far as purchasing another one, if your dealer cannot order it for you then we have no more available. However, if the model was only discontinued recently chances are good many hobby shops still DO have the model. We recommend using our Dealer Locator to contact other dealers in your area who may have the model. You might also try an internet search for R/C sites with swap shops to help you locate your desired model, as well as swap shops.


I am looking for further information on a discontinued product, but I couldn't find anything on your web site. Where can I find the information I need?

We will be happy to assist you. Please be advised, however, that depending upon how old your discontinued item is, we may only have limited information available to provide you. Please contact product support, being sure to provide full detailed information on your model, your full email address and at least 1 other means of daytime contact in your email.


Please explain your warranty coverage.

As with any company's warranty, the warranty period starts from the date of original purchase. Strictly speaking, an item sent for warranty service must include a proof of purchase date. This eliminates any questions about the warranty period and its expiration. Unfortunately, this includes items received as gifts. If an item is purchased by another individual, hopefully you will have no problems in obtaining a receipt to validate a warranty claim, or that individual can send it to us for warranty coverage. Items that are purchased used will have no warranty, neither will an unused item sold to a second owner, unless the original purchase date can be proved. A warranty is only to the original purchaser. A bill of sale between individuals is not considered a valid purchase receipt.

If you believe you have an item which warrants a warranty claim and you are in the U.S. (if you are outside the U.S. please contact the international contact in your region), please refer to our Repair Services page for the shipping address and instructions.

If you have any questions regarding warranty coverage, please do not hesitate to contact our warranty center, Hobby Services, at productsupport@hobbyservices.com, or 217-398-0007 (Monday-Friday 9am-5pm Central Time) or fax at 217-398-7721.


How can I buy blank sheets of AirCore for a project I am working on?

Unfortunately, we are unable to provide blank AirCore stock for sale. We do make available replacement parts but otherwise do not have AirCore stock available uncut.
