I've never done landing gear on a Wonder, but I had some on a couple of Lanier Shrikes. What I found is that when the bird is balanced correctly (so that it won't snap out of turns and crash) it's impossible to flare, so must be landed from a fast glide in a level attitude, allowing it to touch down very gradually, like on a belly landing. Anything else gets a big bounce. Trying to slow it down in the glide prior to touchdown results in ballooning.

The Wonder likes to land the same way. I've never been able to flare mine, but have to bring it in level.

If hand launch is spooking you, do what I did: mix a touch (maybe 1/8" max) up elevator into one of your switches. It makes the nose stay up during launch. I toss mine with full throttle, slightly nose up, and one finger on the "launch" switch. I find I can turn it off as soon as I've released the airplane and I get perfect launches every time. You definitely do not want to launch these birds trimmed the way they are for level flight. They'll go for the dirt every time.

Here's how I did the nosewheel on my Shrike, before I removed the landing gear. The steering servo was upside down, way in the back to help with the nose heavy problem. You might also try putting the nosewheel mount on the backside of the firewall.
