In 2009 a renowned Czech aircraft designer Milan Bříštěla together with his son Martin founded the BRM AERO Ltd. Their first airplane Bristell Classic, an elegant ultra–light low–wing twin–seater with a tricycle undercarriage, turned out to be a stunning success (over 600 sold worldwide). The company has continued to grow and expand their line of products since then.
The latest addition is the Bristell B23, a two–seat all–metal low–wing airplane with a composite main undercarriage certified according to the EASA CS–23/U.S. 14 CFR (FAR) Part 23. The "full–size" B23 featuring a modern full–glass cockpit and latest avionics is a perfect trainer for flying schools as well as comfortable airplane for fun flying and distance travels.
Before you start
- If you are not an experienced RC pilot, plan to have a fully competent pilot check your completed model and help you with your first flights. Even though we have tried to provide you with a thorough instruction manual, RC models are rather complicated and an experienced modeler can quickly check over your model to make sure your first flights are successful.
- Please assemble your model exactly according to these instructions. Do not attempt to modify or change your model in any way, as doing so may adversely change its flying characteristics.
- Before you begin, please check the entire contents of this kit to make sure that no parts are missing or damaged. This will also help you to become familiar with each component of your plane. If you find that any of the parts are either missing or damaged, please contact your dealer immediately for replacement.
- Trial fit each part before gluing it in place. Make sure you are using the correct part and that it fits well before assembling. No amount of glue can make up for a poor fitting part.
- The manual contains a drawing showing the default position of the Centre of Gravity (CG) and recommended control surface throws. Please note it is essential to keep the recommended CG position for the first flight otherwise the model could be unstable, hard to control or even unable to fly at all! Later, you can fine tune the CG position to suit your flying style and skills.
