Warren Gregoire & Associates has been offering luxurious and functional General Aviation control yoke upgrades since 1992- the year we introduced our popular and cost effective slip-on grips. Shortly afterward we began developing leather control yoke covers that are now available for most planes.

All of these products are offered with a 30-day money back guaranty.

When you phone us at 510-282-9300 0r 800-634-0094, a knowledgeable live person usually answers. There is voice mail available during busier periods, if you would like to leave us a message.

American workers individually hand craft our control yoke upgrades, in our Lafayette, California facility, using imported and domestic components.


When you receive our control yoke upgrade, you have a full 30 days to examine and use it in your plane, before you are committed to keeping it. If, during that time, you decide to return it, you may send it back in reasonable condition to receive a full refund of the original purchase price (not including shipping & handling charges). We ask you to phone us before you send it, so we can be sure you have our current and appropriate address, and to help expedite your refund. Please phone 800-634-0094 or 510-282-9300, if you wish to return a purchase.

For leather control yoke covers, it is our policy to repair or replace any Velcro® zippers that may become delaminated from the leather, for as long as the original purchaser owns the aircraft. There is no time limitation, but the leather needs to be in serviceable condition (not worn through and falling apart).

We offer to repair or replace push-to-talk system components that fail during the first year after the purchase (not including misuse or abuse), at no charge. The user is asked to pay for shipping to us, but we pay for return shipping after the service.


We want to give our control yoke upgrade clients ample opportunity to try out the product in their planes before they are committed to keeping it. So we offer all buyers an automatic return privilege that enables them to return it for a full refund of all charges except original shipping and handling, during the first thirty days after receipt. However, in some cases the client might need longer because of bad flying weather, aircraft repairs, annuals, extended travel, advance gift purchase, etc. We generally are open to extending the money back period much longer, even over 60 days, if we are requested to do so.

If you do need to return your purchase, please phone us to be sure you have the current and appropriate address. Use our main phone number 510-282-9300 or our toll free line 800-634-0094 for this important call. This advance notice will enable us to start your refund process early. Then you should receive a credit on the same card or PayPal account you used to place your order, within about one week after we receive your eligible returned merchandise. In event you have paid by check, we shall mail a refund check to you.

You may select whichever carrier you prefer for your return shipment. We find that USPS, Fedex and UPS all are extremely reliable, and they rarely lose or damage a package. This makes a good argument for declining any extra cost insurance. But you should be aware that as the shipper, you are financially responsible in the truly rare event that the package might be lost or damaged. And the carriers offer to take that small risk for you, with insurance, at extra cost. So please purchase insurance, only at your discretion.
