General rules which define the ratio of model’s wingspan to engine capacity, are being followed by almost every manufacturer nowadays. For aerobatic models such as:
S-bach,
Extra,
Edge,
Cap,
the ratio according to various manufacturers is as follows:
Wing span (cm) | Engine’s capacity (cc) |
180 | 20 – 30 |
200 | 50 |
220 | 45 – 60 |
230 | 50 – 70 |
240 | 60 – 80 |
260 | 80 – 100 |
300 | 150 – 170 |
The same rules apply to Giles and Sukhoi which have slightly shorter wings compared with the above.
