Building your first ‘true’ model
aeroplane requires basic cutting skills, interpreting a plan
and careful assembly from following the instructions. The Topaz fits that bill exactly and will reward the owner with terrific flight performance from a simple design.
The fuselage is built up in the conventional manner over the plan with strip and sheet balsa components. The wing is very similar and the whole model can be completed structurally in a surprisingly short time period.
Covering tissue is supplied but the builder will need to purchase taughtening dope/thinners. A simple 50/50 mix will give good results without distorting the structure.
As both the wings and tail are secured by elastic bands, the model is surprisingly ‘damage resistant’. A feature that becomes only too apparent as you learn how to ‘trim’ the Topaz for flight!
The supplied rubber strip and propeller are more than sufficient to provide rewarding climb performance combined with good duration.
The Topaz makes an ideal introduction to the fun of ‘stick and tissue’ models.
