[trikes] DELTA VS TADPOLE for speed

[Chris Heffel]

Don't leave us hanging Ian.   Which is it, the Orange or the Apple?

My GTR is orange, please say orange!

Has anyone tried an Anura with a front hub motor yet?  Can it be done 
with 16" wheels?  I would assume the Anura might do better than the Kett 
with the rider position being further forward (on slippery roads anyway).
