Can someone explain to me what is the difference and benifits of these wheel designs?

In theory, they are suppose to not allow the plane to bounce or reduce the bounce on landings. Since this is the beginner section, most trainers bounce not because of the wheels, but instead because of the landing gear itself. Low bounce tires can be used if this problem is big. Normally, working on your approach and landings reduce the bouncing of a trainer. The tires are made from a shock absorbing material. I've seen many new pilots change over to low bounce wheels with no difference noted. I mentioned eariler, practice will reduce this tendancy.

If i were you, I would get Dubro landing gear. It will do very good for you. I put it on my trainer.

Hi!
There is none...just get the lightest wheels you can get!
Light weight is important...not what kind of rubber/plastic the wheels are made off.

The key to a no-bounce landing is proper technique, not special landing gear. The lighter wheels will help but a lot of touch and go's will help more. Spend your money on fuel and just go fly.

I couldn't agree with Bruce more. Too many times people think that better equipment is what they need to fly better, but what they really need is just good ole practice. Burn a couple of gallons of fuel doing touch and gos and you'll be greasing landings every time. practice, practice, practice!!!

Too many people are prone to change out the landing gear of a trainer if it bounces. It is easier and quicker to do that than it is to learn to land properly. The only thing I did on my trainer, which I still fly by the way, is change the spongey tires to Lite-Flite tires. These things are light weight, relatively soft, and durable. It took very few landings before I could stick it on the double yellow lines on the road at Intergraph. Chad knows where I mean.

the WIRE landin gear produces a lot of bouces.. but the aluminum landin gear it pretty good

Nope not buying it.

I have the most bent out of shape springy gear you will ever want to see on ym avistar and I can grease them so good you can't tell where it stops flying and starts taxi'ing.

Like mentioned before.

Save your money and buy another gallon of fuel.

Ditto with Bruce, RCKen, Faster et. al. While I believe wire gear can have a tendency to amplify a bad touchdown and induce a more obvious bounce, the problem isn't the gear. Planes with wire gear can be greased in just as well as other gear types, they are just a bit more sensitive. Wire gear are springy with little dampening, so if you don't nail the landing, you get a bounce. However, this extra sensitivity is actually a good learning tool IMO, i.e., you have instant feedback that your landing was off. The best solution really is to burn fuel and figure out landings. However, this hobby is about having fun. If the bounce is really bothering you and you need a break from the bounces, you can switch to dural gear or similar with foam wheels. This setup will still bounce on a bad landing, but not as bad as the wire gear/pnumatic tires. Cheers.
