What our customers say

"we waited for a decrease in price and were able to get a small percentage off - so we purchased for our teenage son who enjoyed putting it together. it is very detailed and takes a little bit of time to put together but it runs beautifully and is a nice break from any electronics"

Hippyfooexpensive but solid model to build

"Excellent model, great fit, finish, packaging, manual, runs beautifully ... this has it all. It can run on a built-in battery or a usb adapter. Adequate tools are included. All parts were present."

MeteorMagnetBeautiful technical model

"Impressive! Very good quality and detailed instructions. Some of the parts are tiny and require a little patience when assembling. Need a pair of tweezers for some of the screws. Beautiful little desk display. Fit and finish are all five stars."

WhaledriverVery well designed and great fit and finish

"Boy this was a fun build!! I've done all of the engines and this was my favorite one. Helps to have needle nose pliers for the small nuts and there's a lot! I spent about four days putting it together, working on it off and on throughout the day. Totally worth it if you love building model engines."

LopezChallenging and exciting build

"I was so scared this to be a scam. But it's not, it's what's been promised. The price tag is on the higher end for sure, but looking at the material and the quality, it's totally worth it."

RonnyAbsolute Fantastic!!!!!

"I received this purchase exactly on time. The packaging was outstanding. This is the second Teching product I purchased. The first was the Turbo fan CFM56 jet engine that turned out fantastic. It was a lot of hours, but extremely enjoyable to build. Teching instruction manuals are superb because you get a beautiful booklet with plenty of illustrations. Every part is numbered and packed in foam or plastic. You also receive spare screws and fasteners in case you loose some-like I did. I highly recommend this product."

DesarioTHE BEST MECHANICAL MODEL KIT

"My 14yo is interested in car mechanics so we got this for him as a Christmas present. It took him a while to put together but he did it completely on his own. He's even taken parts off and put them back on afterwards. I think he's really proud of himself for being able to do this project. It's expensive but the product is great quality. Very happy with this purchase!"

MavenQuality is great!
