Thames & Kosmos Ultralight Airplanes STEM Experiment Kit | Build 5 Gliders | Learn How Airplanes Work | for Ages 8+ | Design Your Own Glider | Learn Physics and Aerodynamics

I personally really loved this. The models do fly, but they require patience to adjust the pieces properly. The material does at first look like it will fall apart, but in fact it doesn't!! It's deliberately very lightweight to facilitate the flying. The design is actually pretty ingenious and holds together way, way better than I expected. The models are still delicate, but incredibly, NOTHING broke in testing and in total only two or three pieces fell off. These are far from the balsa planes of my youth, better designed, and much sturdier. For a relative novice like myself, this set is perfect!

Well, I am not in aviation or model making, but I did expect something else when it's called "Ultralight" airplanes... They are definitely not light ones, they have basic frame and fairly large sturdy wings. It was fun to assemble and play with, I liked it, but honestly, I was expecting something I did maybe 35 years ago, with ultra-thin wooden frame and wings made of paper that was see-through, and those where so light, you could use static electricity to push them through the air, this is definitely not something like that, nor very light. It's still decent and fun product, just not clearly explained what they are.

Bought this as a birthday gift for our 11 year old. Was worried it might be a little to young for him, but he loved it! Thanks for the quick shipping and fun product!

This ruined my life, the viscosity of the anti Newtonian law magnetism lock for the formula of the charged atom neuron anti viscostic property greatly reduces the X factor such as dyslexic features that greatly induces the velocity of the coma

Zero Stars! I am a pilot and I couldn't get this to fly. Don't buy! Don't waste your money! Everything is just about wrong with this set. Does not fly. The wings slide off, the weight drops off as soon as you throw to launch it. After one build the bamboo sticks wear out. The balance and aerodynamics are wrong. You will be lucky if this flies more than 5 feet. You can only build one model at a time. Save your $20, instead just buy the simple balsa gliders. You can get 10 for this price and all of the will fly, and kids can have fun.

As a lic fixed wing pilot, and pending chopper pilot, I LOVE the combos and 'fun" of these things of my tri-state Ky, Tenn, Va mountains!

At the price I got it at, I should have bought ten

Don't want now.

Great product very innovative and educational a must

Fun 15 minute craft activity for kids, flies quite well. 9&11 year old could built it without help. I would have given it five stars, but feel bad about all the single use plastic.

very good but at time difficult to insert some pieces especially the verticle stabiliser. It was frustrating, but the effort was worth it. You have to do it only once

Not good. Quality is poor. The parts have to be joined using high force and strength so instead of the kids, its an adult who actually needs to fix all parts. Also after fixing it well, the plane didn't fly and crashed and the wings cracked. Its an expensive buy and still not of use.

Very Disapointed Wing panels very flimsy 2 tore after 5-6 flight attempts . Bamboo dowels are not consistent width/depth some are too big some are too small a few are just right . As stated on another review the resulting gliders are not very aerodynamic or adjustable and the front weight fell off every single time . All in all a very big disapointment for my 8 year old who was really looking forward to this . Garrett.
