Auto Grand Prix U-9

Sadly, I may be defeated by rubber bands. I was a little disappointed by the use of toothpicks. I had recently built a couple of other models, from another vendor, that relied heavily on toothpicks. No a fan of toothpicks.
That's the biggest reason for the 3 stars...toothpicks and rubberbands. Not a fan, I fear the other build will be a similar complaint. Ah well.

awaiting some spares for completion

Pour la 7eme construction, j'avoue que j'ai beaucoup transpiré, mais avec patience et persévérance le résultat est magnifique

It may be an unfair rating at this time, as I am still working on it. I am on the verge of losing patience because of the difficulty of installing the rubber bands. Getting the thick bands into the tiny slots, especially when the slot already has a band in it, is extremely difficult, to say the least. Very time consuming to get past this step. I have built other Ugear models, none have caused me anywhere near the difficulty of just this one step. I will review again when I have finished assembly (I hope I get it done!)

I just finished this model. It was a real challenge to put this one together. The rubber band assemblies were the most challenging. Trying to get the thicker bands through the holes and all the same length was very difficult. I had to use all of the available spare parts because I kept breaking the parts. But i finally got it. Other than that this model is fantastic. It runs great!!! Make sure you use plenty of wax on the moving parts. I love these Ugears models. The problem is which one should I do next. You guys are great. I love these models. Please keep up the good work.

Ich bin ein erfahrener Modellbauer.
An diesem Modell bemängle ich die Zahnradverbindungen. Die Umschaltung für die Fahrrichtung funktioniert nicht. Die Zahnräder stehen in sich auf und blockieren. Es ist mir völlig unerklärlich wie dieses Modell sich in Bewegung setzt. Als Standmodell sieht es gut aus.

I use to build motorbike trikes, but due to poor health had to give it up. I saw these kits and thought I'd give it a go. As much I enjoyed building it, it does not work. I was very careful and applied the wax accordingly. Because it's wood may be it has absorbed moisture, which causes the joints to swell. After letting it stand, still no movement. When it is cranked. I can see the first cog moving but nothing else. Not impressed.

I really enjoyed putting this together. This was my first try at Ugears and I did break a couple parts that I was able to replace with a spare part except for one I was able to glue. If I didn’t show you you wouldn’t know. My only problem I can’t make it run. I guess a gear is not lined up and I am not going to take it apart to see. I will build another model and be more careful. I do think it is important to take your time building these. I was very impressed with how precise the parts fit together.

My my first ugear model and not my last one! Quality is fantastic and instructions are quite clear. I only made a couple of mistakes but I could resolve them. There are some spare parts but I didn’t need to use any of them.

It cost me 10h of work approx. It is recommended to use wax properly if you want your car to move, else there are too many friction. I had to put wax at the very end on the gears as if it was oil in a car. Quite funny.

Only one comment, I don’t understand the purpose of the wheel with rubber on the left side, plus it is the only part that doesn’t hold well and I had to put some glue there.

Only had this model 10 months and the exposed rubber bands have rotted already.very disappointed.
