Please note that due to the discontinuation of the OS .25FP and the Norvel
.25 going unavailable along with the manufacturers increasing the displacement
of the .25 engines, we are opening up the specifications so the Thunder Tiger
GP .28 can be used in Stock Class. This engine is available for approximately
$65 at this point, comparable to the Norvel and OS engines previously used.
Rules for Gremlin Combat
This is a one design contest for RC Combat. The plane will be the R/C
Combat Gremlin (RCM 12/92 or RA Cores kit), and the engine will be a plain
bearing .28 or smaller engine. The Gremlin has been designed as a light
plane that will stop and drop in case of a mid-air, minimizing the hazard
to pilots and spectators from falling debris. The combat will consist of
two planes at a time flying a predetermined number of rounds. Each plane
will have a 20' streamer attached to a 20' string, with the idea being
to cut your opponents streamer before they can cut yours. The rules listed
below call for a 3 minute round. Experience has shown that 2-4 minute rounds
are best due to the concentration level required of the pilots.
The Gremlin is to have a minimum wing span of 44" and a maximum
span of 48". Wing construction will be as designed, no addition of
Carbon Fiber or Metal to spars or leading edges. Engine is to be a stock
plain bearing (bushing) .28 engine with stock muffler.
All planes will be inspected by the CD or CD appointed individuals prior
to being flown in this event. The normal wingspan is 48" as designed
but the trimming of wingtips to remove crash damage and even out the wing
is allowed to 44".
Rules of Engagement
- Combat will consist of 2 planes at a time flying a 3 minute Round.
Combat will begin when the "Timing" judge calls "Engage",
and ends when the command "Break" has been given.
- Then will be two (2) Judges per round of combat. One Judge will watch
that the contestants stay in the "box" and will also be the timer.
This judge will call "Engage" and "Break". The second
Judge will be the "Cut" judge.
- Removing all or any portion of your opponents streamer is a "Cut"
and constitutes an immediate win.
Contestants will be allowed 2 minutes to get airborne after they are
called to fly. If they are not ready at that time they will be placed at
the end of the queue. If they an still not able to get airborne, they will
receive a loss for that round. When one set of contestants is called to
fly, the following match up will be told they are "on deck" and
to begin getting prepared to fly.
Streamers will be supplied by the CD. They will be crepe paper 20'
long and approximately 2" wide at the end of a 20' cotton string.
All combat will take place in a designated box. Flying out of this
box during combat will result in a warning. Repeated offenses will be penalized
by a loss for that round.
Contestants will be allowed only one (1) model per round, but may switch
to an alternate model of their choice for following rounds. Altemate models
must meet the specifications listed above.
The CD may, at his discretion, reinspect any aircraft he suspects may
have been rendered unsafe for flight during an earlier round. If the CD
pronounces that aircraft as unsafe, it will not be used for later rounds.
The pilot of the aircraft removed may make field repairs and resubmit the
aircraft to the CD for inspection. The CD is obligated to inspect an aircraft
resubmitted for safety inspection as soon as the aircraft, is presented
to him. If it passes inspection, the airplane is immediately available
for use. The judgement of the CD on safety matters cannot be protested.
Scoring will be three points for a "cut" as designated above
and a single point for a spot landing closest to the designated marker
(measured to the spinner) or for the opponent landing prior to the end
of the round (DNF - did not finish).
In the case of a tie at the end of the normal rounds, a flyoff can
- The "Cut" judge will determine if a streamer was cut. If
either pilots streamer deteriorates prior to "engage" being called,
both pilots will land and will re-fly the match at the end of the round.
Losing any portion of your streamer after "Engage" has been called
will result in a loss for that round.
- In cases where no cut is made after 3 minutes, the contestant landing
closest to a designated spot will be declared the winner of that round.
Some contests allow for spot landings after a cut was made for additional
- Landing for ANY reason during the 3 minutes after "Engage"
has been called is an automatic loss for that round (DNF - did not finish)
and a single point for the remaining flyer. One restart per round is allowed
prior to "Engage" being called.
- In the case of a mid-air, the last fuselage to reach the ground will
be declared the winner. This will be determined by the "Cut"
