Horton/Robertson differences

[hharney]

If it has a Robertson the seller would be smart enough to brag about that system as it is worth much more money. If it just says STOL kit it's probably a Horton. I have never seen a STOL kit without the boom fairings. Not saying they aren't out there I just think that's a poor identifying component. Why would you rely on the ad without calling and talking to someone that represents the plane? Anyone that knows anything should be able to verify the system by extending the flaps and see if the ailerons are inter-connected.
