SAM 95 BOHEMIA RC OLDTIMERS RULES FOR THE PERIOD 2013-2015
A. General rules
SAM 95 Bohemia approves oldtime model with the origin before 1.1.1961. Competitor may be asked to proof the date of model origin using a plan or photographs. Member of the competition organiser team can measure and weight the model and compare the data( or their multiples) according to the plan to proof the rules were met.
It is not necessary to check the model which has its own ID card (ID card is a document issued by SAM club approving that model has been checked and meets rules)
The year of origin, name of the model and name of the designer should be on the model surface.
The exchange of the airfoil is permitted, proportional thickness should be maintain.
Scaling up and down is possible. The specific rules may forbid scaling. Tail unit can be prepared to adapt RC installation. They can be splitted up in any place but the shape must not be changed or scaled. Maximum weight of the model is 5000 gramms, maximum span is 3500 mm. Minum weght is 12 g/dm2. The specific rule can admit different rule.
The wing surface may be planked in case the original wings of the model were planked.
The construction of the model can be reinforced due to the weight of RC equipment. The original material is recommended to use. Inacessible materials may be replaced by balsa wood. Carbon, glassfibre and any modern material are prohibited.
Position of the landing gear must be coincident with the original model, single wheel landing gear can be changed to two-wheeld gear but no vice versa.
The propeller must be two bladed non folding. Metallic props are prohibited. Folding propellers are admitted in E categories and also in other categories if it the original model was fitted with folding propeller.
It is higly recommended for all competitors to have aeromedeler insurance as the competitor is fully responsible for damages. For the security reasons the competitor is obliged to obey the instruction of the competition committee. Before take off the competitor must demonstrate to timekeeper thet the right model is chosen in the transmitter choice and to proof the engine switch on-off system funcion.
Repetitive swith on after the end of the allowed motor run in E categories is prohibited. In case the motor is necessary to switch on (for example for the purposse to save the model) the repetitive switch on must be announced to timekeeper. The result of the flight in the round is 0 points.
The model flight is measured by timekeeper appointed by competition committee. Two models with different design may be used in each category.If both models enter the fly off the competitor must decide to fly only one of them. Both models must appear in the results. The competitor must control his model himself. Three helpers are allowed.
In case of using Li-xx batteries any number of cell sis allowed but the voltage must meet the rules.
All categories are flown in rounds or free within given flight time according the the decesion of the competition committee. The competition committee is responsible for competition smooth running.
In case of identical flight times the fly off is held. The competition committee and competitors may set the placing using drawing or any other way. The time of fly offs must be announced by the competition committee 15 minutes beforehand. The competition committee decides the fly-off system. The maximum fly-off flight time can be unlimited.
B, The Compettition Committee responsibility (named as CC in the following text)
CC is obliged to check if the rules are met. The rules can be adopted to the local conditions.
CC is obliged to adopt the way of flying to the used Tx frequencies.
If the wind speed reached 8m/s the competition can be interrupted or finished. The exchieved results will be used to score.
CC will decide the landing area.
CC must assure safe competition running.
Tx frequencies can be checked at any time during the competition (if the announced frequency is in accoradnce with the frequency in application form). If there are several same frequencies the table with pin sis used. In case the competitor takes the pin he must take off within ten minutes not to block the frequeny unnecessarily.
C, Categories
ARC – (OTVR)
Model without engine must meet general rules. The span of the model can be 3.5 meters (138 inches), max weight is 5 kilogramms, tow line must be 100 meters long (also in case the pully is used). Bungee is permitted with 20 meters of rubber and 80 meters of line. CC will prepare basis with A and B line with a maximum distance of 170 meters. The anchor of bungee must be on the line A and the maximum extension of the bungee is up to the line B.
Number of flights: Competitor is authorized to fly five flights without any correction flight. The result is scored using three best flights. Maximum flight is 300 sec. In case of flyoff the way of fly off will be decided by CC. If the model lands out of the area marked out for landing the flight is cored „0“. To judge the landing the model nose is decisive.

If the model lands out of the area marked out for landing the flight is cored „0“. To judge the landing the model nose is decisive.
Pokud model přistane mimo prostor vytýčený pořadatelem pro přistání, je celý let hodnocen nula body. Pro posouzení přistání, je rozhodující špička modelu.
