type of step-by-step setup instructions for a variety of other model types.
Due to potential unforeseen changes in production procedures, the information contained in
this manual is subject to change without notice. No part of this manual may be reproduced in
any form, at any time, without prior permission.

during your hobby’s “off season” to ensure safe operation.
