Why did I not go with the Axi's?
Actually I looked at them a long time ago. Mookie1 did an elec conversion to a VQ Models 83" P38 and got me started on this whole P38 affair.
VQ = $600.00. N/M = $249.00
Axi(4130-16's?) around $170.00 a piece. TP 3520's $50.00 per.
I figure I'm ahead of the game so to speak by what $420.00?
Should put a good down payment on the packs.

Carl,
Something that may have been a problem on your 3520. Supposedly the stock bearings are marginal at best. Noisey and sloppy. Replace them and they get much better. I guess I'll do it to mine when the time comes. Still cheaper the the Axi's. LOL

Oh and this may help with how big it is.
I dry fitted some of it together and threw the 52" version on top, just so you get some idea of the scale.
I'm impressed to say the least at the workmanship on it. Somebody designed it to be light.
Now just have to figure out how to build it to fit in the van. Or I guess I could strap it to the roof rack.
