E-flite Main Landing Gear System Viper 70mm- EFLG7709 Wheels Gear Retracts & Accys

Good design, seems sturdy and durable.Now need to mount in a plane and put it to the test.

They fit well and the retractable mechanism works well at first. However they will not handle harder landings. The struts easily bend out of shape and quickly become lose and sloppy. They both quit working after two trips to the flying field . Approximately 6 flights and landings they became lose and sloppy. After the 6 flights they stopped working constantly. On and off. Then just stopped working all together. They are very inexpensive and good for test flights on a new built plane .
