I might try fitting a key chain cam and flying over two markers that are a known distance apart . the video should give an accurate time between the markers. I will do this in both directions and find the average {similar to timing at Bonneville} that should eliminate any wind induced variation. i will look into the V3 method too. sounds interesting.
Good luck with the twin parkjet.
Radar guns ... talk to Stu - he has one and hasn't been too successful. Anyone who wants to stand with a gun to get a reading of a PKJ passing about 20ft of the ground, 10ft to one side is braver than I !! Forget them and save money !! Even a Police Pro machine has difficulty with a model.

The V3 pitot will give good results - I've had one for more than a year and it's very good. I want another .. as I keep swapping it from model to model ...

What I really like about it - it remembers last speed ... so you can unplug ... go home and power up - read it again.
