I don't see any reason to clip his wings.... sure, it makes it easier to chase him down if he were to get out, but again, I don't see it any safer, because this means he'll end up on the floor where he could potentially get stepped on. There are also a lot of fun things on or near the floor to chew on...
I once had 5 adult, flighted budgies. Two came from a breeder (parent raised), the other three came from pet stores, and when the owners no longer wanted them, gave them to me. None were tame and friendly. I decided to try a little "experiment". I started out by feeding them first thing in the morning by hand. Now, mind you, I only feed my birds enough food to last one day, so they do not have food available to them 24/7. I'd try to wait at least 5-15 minutes and if they didn't eat, that was ok! I would replenish their food dishes for the day and try again the next day. Five budgies. All flighted. None tame. Monkey see, monkey do!

Did that for about a month. Well, two weeks in, instead of feeding them inside the cage, I was feeding them just outside the cage door. Two weeks of that, I then tried feeding them from about 4 feet away from the cage. After they were done eating, I could get them back in their cage by replenishing the food dishes.

Experiment complete. I was able to get 5 budgies to trust me, to an extent. That's all I wanted to do. I could have done more, but I didn't feel the need to.
But............. I apparently wasn't done just yet!
I had a female cockatiel that was hand raised and a pet at one point in time in her life, but her human, a kid, grew up and discovered sports and girls. (he could have been the one who hand fed her, too! he had her parents as well) Well, she (and her family - more on that later...) ended up getting ignored as no one had time for her. I ended up getting her and her family. When I got her, she didn't show any interest in human interaction, and I was ok with that. If my birds want human interaction, I'll oblige! But I don't need every single bird of mine to be tame, friendly and demanding attention! As long as they are happy and content, I'm ok with that!
Remember when I said monkey see, monkey do? Well, Sunshine ended up following me around the room in the morning when I was feeding everyone. She even landed on me a couple of times. At first, I thought she was a different bird! Until she flew off. Sunshine had landed on me, behind my head, so I thought she was Casey, but Casey isn't as heavy as Sunshine is. When Sunshine took off a moment later and I turned and look to see "Casey" fly off, I realized it was Sunshine!
It took two freakin weeks! Two freakin weeks for this dumb human to realize that Sunshine had decided she wanted human interaction, too! But not just *any* interaction! It had to be the same as what the budgies were getting!!! So I started feeding her by hand!

Insert Faye. Another rehomed cockatiel. She had at least 3 homes prior to mine, and probably all 3 were crappy. The previous one fed her a horrible diet, when the food dish was "empty", instead of throwing the waste away, they'd dump it on the bottom of the cage and refill the dish. With wild bird seed. Bar spacing on the cage was large enough that mice, in broad daylight, were climbing through the bars and rummaging through the bottom. The tray had a nice big rusted out hole in it, too. Sickening thought that these people actually tried to breed her! Thankfully, it was not a success! Home before that? Well, I know she spent a lot of time living inside a screened in porch during the warmer months, no doubt on a poor diet.
When Faye came to me, she was very scared and didn't really want to have any interactions with me... but she was watching me feed Sunshine. Well, if Sunshine can have food from me, she wants it, too! Please take note of her behavior. Also, look at the cockatiel behind her! She's eating food! So Faye doesn't *HAVE* to eat from my hand, but she's choosing to!

And now compare it to this video.... see just how much that behavior has changed.

Faye got to the point that she was *demanding* being fed by hand rather than eating out of a dish! Even if I stopped feeding them for several weeks, or even months, occasionally she'd still demand it!
Anyway...... since my "experiment" had apparently not ended with the budgies, but moved on to the cockatiels as well, I decided to see if I could get the other tiels more comfortable with me! Which includes Tomi Girl, a cockatiel that was nearly starved to death when I took her in (over 40% underweight! possibly even around 50%) and had been in at least two homes, and Sunshine's parents, Pistachio and Kiwi. Tomi Girl was kind of stand-offish with humans, Kiwi didn't really mind humans much as long as you left her alone and Pistachio was terrified of humans. If he thought you meant any ill will towards him, even if you were walking past him, he would take off flying! He would do whatever he could to avoid humans!
Through feeding the cockatiels by hand every day, I was able to get them comfortable eating from my hands, then touching my hands, then eventually standing and even hopping onto my hands for food. At first, they didn't like the idea, and if they were brave enough, would grab a piece of food, then take off running or flying! They were not comfortable with the idea at all!
The most amazing change though was Pistachio. One day he just kind of got over his fear (not to say he's tame and friendly, just his extreme fear of humans). He was trying to forage around on the ground and couldn't find much food, while I was standing near with food in my hand. He decided to fly straight up from the floor and onto my hand. There wasn't much food left, so he stayed on my hand as I went and got more food for him. Another time, he landed on my shoulder, and yet again, I had to painfully slowly walk over to the food buckets (so as not to freak him out) and get more food for him.
The following video shows Tomi Girl, then Pistachio (who is now 18+ years old, been with me for nearly 11 years), then Casey climbing up my arm. (Tomi Girl also makes a reappearance!)

Although I hardly ever feed the cockatiels by hand now-a-days, Pistachio is always the second cockatiel to come over and start eating from my hand when I do offer food by hand! (Casey, my first cockatiel, tame and sweet, being the first!)
