Ian, Is that the recommended placement/design of the landing gear?

The top of the struts look real close to the underside of the wing. A hard landing might crack the sheeting above. The support-plate between the gear-wire and fuse-bottom is a good design.. but when the struts "spread" on landing.. the top of them might spring "up" enough to make contact.

Maybe there's more clearance than it looks, from the pics..? A simple safeguard would be to attach a horizontal piece of music-wire across; just below the bottom clamp.. by Silver-soldering it to both struts. Wire gear will bend.. and the wire on yours looks a bit small in diameter for the model.. and the unsupported length of the legs IMO.

Here's a couple pics of one of my models that has this application.

Not my best example of soldering.. but it held-up through dozens of flights.. and is still solid today.

This mod. would help your model to track straighter on take-off.. as well as keeping the legs from "spreading-apart".. which could cause the prop to strike the ground.

Having to frequently bend the gear back-straight, will stress/loosen the upper-binding. Just some food for thought...

The Gazelle wasn't designed with landing gear - this is one of my afterthoughts and I put it where it would fit.

I could say that I only intend to do perfect landings Huh... but I will follow your advice and put a cross brace on it.

My recent batch of piano wire is quite brittle - it is more likely to snap than bend!

Really.. Huh... that's surprising.. and sucks. I've never encountered that.. and I have a LOT of music-wire. I've never had to heat any of it prior to bending coils.. or tight angles. I use K & S exclusively though.

Do you have any wire left-over from the gear-stock? If so; I'd use that. Cut it to a length 1" longer than you need for the brace.. bend your angles down.. 1/2" ea. side to match the angle of your struts, bind-it with copper-wire and solder-it.

Greased-landings are illusive.. They're great when they happen.. but a hard landing can twist wire-gear like a pretzel. Without enough support.. the fuse could be damaged.. or even worse.. the wing. A strut/wheel could deflect upward.. and take-out a rib-bay. Shocked LOL.. sorry.. I'm a realist.
