Now the fun begins!!!

Its also quite heavy for a TDR but I can play around with that a little should I need.

Would that little extra weight work in your favour?? I'm just thinking if it's taken up high & put in a vertical dive then that little extra would give it a bit more speed on the exit wouldn't it??. What are the rules for a record, does it have to be traveling along a horizontal line for a set distance??

Yes it does, before it enters the course or the timed area it has to be in level flight for 100m.

2.5. SPECIAL RULES FOR SPEED RECORDS IN A STRAIGHT LINE

1. 2.5.1. Base:
   For model aircraft of the Free Flight sub-classes, the record is measured over a base of 50 m for modelaircraft with elastic type motors and of 100 m for model aircraft with piston type motors.
   The course must be flown in both directions within 30 minutes.
   For radio controlled model aircraft the base must be 200 m, and it must be traversed in both directionswithout any intermediate landing.
   The altitude of the model aircraft must remain below 35 m and above 5 m during the 100 m entry and 200m course. These altitudes are measured from the point where the pilot is standing.
   The dossier of the record must include a certified measurement of the course and a statement of themethods used to determine altitude and speed.
   For radio control speed record attempts the model aircraft must be fitted with a throttle or any otherdevice to stop the motor by radio control.
   
2. 2.5.2. Timing:
   The timing of speed records must be accomplished by timing instruments approved by the organisingNational Airsports Control. If electronic stopwatches are used, timekeeping must be effected by twotimekeepers, utilising devices which register to at least 1/100 of a second. The difference between thetimes registered by the two timekeepers must not exceed 0.05 second. Automatic and other electronictiming devices which register a single time are allowed, provided the system is properly documented inthe dossier and approved by the NAC of the claimant(s).
   For speeds above 300km/h, manual activation of timing devices is not permitted. Only automatic meansof timing which eliminate human error factors are permitted and must be certified accurate within 1/100 ofa second.
   The mean of the two speeds of the two runs over the timing base gives the record speed.

Where is the 4530 now?

Used to be in the TDR, now in a box. It's going to be replaced by Pyro. I may sell it, I can't see myself to need that power, ever.
