3.15 CLASS P: ALES RADIAN (or similar 2m All Foam Electric Glider)
(ALES = Altitude Limited Electric Soaring)
The intent of this competition is to provide a simple set of rules for a fun
event. Open to Radian electric gliders or equivalent 2m all foam models.
Major modifications to the aircraft may lead to condemnation by your fellow
The object is to fly three 7 minutes flights over 3 rounds with a bonus for
landing. Launch height is limited to 200m and motor run time to 30 seconds.
A Contest Director may decide to mass launch groups of pilots to add to the
fun of the event. The CD may use group scoring in this instance but points
will not be eligible for any record claims or NDC.

(b) You can recharge or swap batteries between flights
(c) Flights will be scored one point for each second flown up to 7 minutes (i.e.
420 points) then one point lost for each second flown over this time.
(d) Launch height is limited to 200m. Height will be controlled by an Altimeter
switch placed in line with the throttle channel. Refer section 2.8.
(e) A landing bonus of 50 points will be awarded if the whole of the model stops
inside a 7 metre diameter circle; 25 points if any part of the model stops
inside a 15 metre diameter circle; zero points if outside the 15m circle.
(f) Timing of flight is to commence at launch of the model, from the moment it
leaves the launchers hand. Maximum motor run time is 30 seconds, to be
controlled by the onboard switch. Flight timing stops as soon as the model

restarted for any reason, the timekeeper will stop the watch immediately and
landing points will be lost.
(h) No re-flights are permitted.

(j) The model must be airborne at the end of the round the flight time for the
flight & landing to count.
