The plan shows a 36" and 42" Tomboy model, and we propose three different power sources in them, to experiment and work out a formula that gives all power sources with equivalent engine/motor run times.

Announcing a new SAM 600 "Tomboy" R/C fun-fly event.
To all those people not familiar with the aims of SAM 600, we offer the following background.
We specialise in building & flying Vintage & Nostalgic models that are classic free flight models dating back to the pre-war days of the 30's and 40's. These models are sometimes known as Old-Timers (the models are old-timers, not the modellers). Some would disagree with this statement.
The advantage of flying these models with R/C is that under normal conditions, there is no chasing them. When you develop the skill you just land them back at your feet, this is casual and enjoyable flying conducted at a leisurely
pace.
If you like the old fashioned balsa & tissue building and take some pride in having your creation fly well, maybe you should take a second look at this type of model.
There are hundreds of different designs to choose from, they use only rudder, elevator, & motor control. Therefore there is no expensive computer radio to purchase, a simple 3 channel radio is sufficient, although some members fly
with a 4 or 6 channel set.
We get enormous satisfaction from building & flying these models, either in competition or just for fun.So can you.
If you are tired of the fast, can't-take-your-eyes-off-for-a-second models, maybe this leisurely way of flying is what you are looking for. There are no sweaty palms in this group of flyers.
We are in fact formulating a new class of flying designed specifically for newcomers as well as experienced flyers to our hobby.
This will be a ONE-design model competition that will be very low key, enabling a newcomer to fly without the pressures of round times, fly off's, etc. The model we propose to submit is the "TOMBOY", a Vic Smeed British
design from the early 1950's.

This model is a high wing, cabin, free flight model of 36" (or 42") span designed as a beginners first power model, hence it was, and is, very stable & forgiving. Even more so when you put R/C in it.
NEW TOMBOY COMP RULES
The model must be built to the original Aeromodeller plan with either the 36” or 44” wing & can not be altered except to increase wood sizes for extra strength.POWER is to be either diesel or glo plug motor up to 1cc capacity (unfortunately we will have to drop electric power as it seems impossible to formulate battery sizes to be compatible with the i/c engines , sorry )
This will be a fuel allocation event with 3cc of fuel , this can be a Mills 75 or MP jet .6 cc standard tank or a special tank made to 3cc capacity; checked for size on the day of the comp Control will be rudder; elevator with motor control as an option Flying will be all day on the day of other competitions; will cease when flyoff's start, you will be allowed 4 official flights during the duration of the comp whether it be a 1 or 2 day comp & and the best single flight wins NO FLYOFF'S
The competition will be flown in conjunction with other events, but will have no time constraints other than to start at the beginning of the days flying & stop when the fly-off's for other events start. You will be allowed 4 flights over the length of the competition and the person with the longest flight will be the winner. It's as simple as that. |
