I talked with Tam this morning and he seems really interested in this project...
He is leaving for E-Jets in Ohio later this week and is getting ready for that, but when he gets back he wants to work on one.

He said the two 6s setups would give about 15 pounds thrust at 230 mph efflux... very light it would fly like a glider

At 16 to 17 pounds it would fly great!

Here's a video of a HUGE 25 pound Comp ARF hawk he did with two fans... and there is losses in that ducting
with the A-10 you won't have ducting losses.

this is not the new 7 stator fan which will sound sweeter... but gives you the idea of what it can do

later
