I saw the Positron awhile ago and thought it looked good, so used the
ideas and built one. Since then I've built two variants.
 |
The major difference from
the first is the use of an airfoil section, not a flat plate. |
| Delta 1, 370*570mm flat
3mm plate wing. It flew well but only on full power on a 6v motor with a 6*3 folding prop.
Very fast and good fun but 2.5min flight times were a bit short. When the power stops the
landings are almost immediate, no glide at all. |

 |
Delta 2, 320*600
with an Eh3021 section. The one I'm flying at the moment. |
| After the first flight
I decided to try a 7.2v motor instead of the 6v, hoping the performance would still
be good with an increase in the flight times. Its brilliant, it climbs out at 45deg.
and fly's at full power for almost 5min. |
