the 7000 would be best to use just so that people don't whine about it out at the field, if i were on private property i would fly it with the 6100. but at a club with other people checking your plane out just stick with the 7000.
To make a recommendation like this is just plain dangerous. Shouldn't choose the proper receiver to use simply because you think somebody might check your plane. You choose the correct receiver because it is the right one to use. If you use the 6100 in a larger plane (not park flyer size) you risk the plane flying away from your because it's a limited range receiver. A fly away could easily damage property, injure somebody, or even kill somebody. Is the lawsuit you face worth the few extra dollars you saved because you didn't want to use the proper receiver.
As I said, you should use the proper receiver in the role it was designed for. In the same way that you choose a servo by the application you have it in, or the proper sized engine for the plane you are flying, you should choose the proper receiver for your plane. Use the 6100 in small planes such as foamies and park flyers. You use the 7000 in larger sized planes.
