    Re: SAM Speed 400 LMR models Rules

    These are the rules and task that apply to the Speed 400 LMR event.

    5E. Speed 400 LMR Event:-


    1.Models may be based on any approved SAM Old Timer gas model airplane. Scaling is allowed. There is a 16 oz. minimum weight requirement. By rule, North American Old Timer designs are limited to Dec. 31, 1942 and older.
    2.Thrust will be provided by a non-folding, non-metal propeller of any size driven directly (i.e., no reduction drives) by a Graupner Speed 400 6-volt permanent magnet ferrite motor without ball bearings. After purchase, motor timing adjustments are allowed. To prevent damage to the motor, folding propellers may be used provided they are locked in the fixed position for normal flight.
    3.The battery may be six NiCad cells or six NiMh cells, or two Lithium chemistry cells of any capacity with manufacturer’s label clearly visible.
    4.The power to the motor must be radio controlled but may be on/off or ESC.
    5.Flights may be hand launched with the landing area determined by field rules.
    6.The motor may be run only during the first 180 seconds of the flight; Any running of the motor afterwards results in a zero score for that flight. This time may be changed at the discretion of the CD.
    7.The model’s score is the sum of the best two of four 15 minute max flights.

    Re: SAM Speed 400 LMR models

    Here is my suggested setup for the Speed 400 LMR event and the components are listed.
    The prices may vary from the time I checked them for this article.

    You will need:
    SPEED 400 6Vdc Electric MotorSPEED 400 6V Electric MotorProduct# GR3321 $7.99

    I might suggest getting a spare motor or two just in case, this event really pushes the motor and failures
    and worn motors happen. But the motors are not expensive at all.

    20 Amp Microprocessor Motor ControllerFor 4 to 8 Ni, 2 to 3 Li-Po cells, 12 to 15
    AmpsProduct# JES020Price: $37.99

    Collet Prop Adapter for 2.3mm Shaft, M5 Collet type Prop shaft adapters hold tighter
    Product# MJ4701Price: $4.40

    I fly a 6x4 APC E prop on mine:
    6x4 Thin Electric PropSpecial Thin props for Electric flightProduct# PE06040EPrice: $2.00


    Pro Lite V2 2 Cell 1350 mAh 7.4V 20C LiPoly Pack1350 Pro Lite V2 with cell balance
    connector Product# TP13202Price: $32.99

    Here is also another pack that works well.
    Thirty 2 Cell 7.4V 1200 mAh LiPoly Pack1200 mAh packs, discharge at up to 36 amps
    Product# XQ12002Price: $25.70
    It is a little larger and heavier but puts out a slightly higher voltage, maybe
    about .4 volts more for the pack. Kind of depends how light you build the plane.
    So that you are right at the 16 oz minimum weight rule.

    You will need connectors for the battery and ESC and maybe to the motor
    I use the HLK003 connecotors but maybe you have your favorite.
    I show how to setup the connectors in a different post in this thread.
