Important/General Notes - Carf-Models Ultra Lightning Instruction Manual

Attention !
This 'jet' aircraft is a high-end product and can create an enormous risk for both pilot and spec-
tators, if not handled with care, and used according to the instructions. Make sure that you oper-
ate your 'Ultra Lightning' according to the AMA rules, or those laws and regulations governing
model flying in the country of use.
The engine, landing gear, servos, linkages and control surfaces have to be attached properly.
Please use only the recommended servos and accessories. Make sure that the 'Centre of
Gravity' is located in the recommended place. Use the nose heavy end of the CG range for your
first flights. A tail heavy plane can be an enormous danger for you and all spectators. Fix any
weights, and heavy items like batteries, very securely into the plane.
Make sure that the plane is secured properly

Important/General Notes

Elastic Hinges:
The ailerons, elevators, flaps and rudders are all hinged already for you - laminated in the mould
and attached with a special nylon hinge-cloth, sandwiched between the outer skin and the foam.
This nylon hinge is 100% safe and durable. You will never have to worry about breaking it, or
wearing it out. There is no gap at all on the top side of the surface, and there is a very narrow
slot in the bottom surface, where the control surface slides under the skin during 'down' throw.
This means that the hinge axis line is on the top surface of the wing, not in the centre. This is
NOT a disadvantage, but you need to program in about 10% NEGATIVE differential in your
transmitter. This means that the 'down' throw needs to be about 10% more than the 'up' throw.
