Hi Dave
After our discussion last night. I completed my T 28, lots of mucking around but replaced the rooted gear door servo, all working sweet know.
I amp tested the standard ESC with 2 brand new (never used) 4000 mAh 4S Nanotech.
First I calibrated the throttle then did 2 tests with 2 different batteries.
Both tests gave almost identical results with no load or power drop off after 30 seconds of full throttle.
580 watts 36.2 amps @ 16 volts.
The data on the motor suggests that it is a 500kv motor that would amount to about 8000 rpm.
It certainly feels like it is pulling pretty hard to me but to be sure the factory 50 amp ESC is doing its job I am going to remove it and drop in a Turnigy PLUSH 60 amp and do the test again.
Watch this space.

Just completed the same tests with the new Turnigy Plush 60amp speedie, results were almost identical, holding a steady 36amps at full throttle.
I recon George must have a different prop or he is running his on 5S.
Will have to get my beastie in the air now to see how it goes.

Very Interesting, as the results are very similar to daves results, peaking at about 34 amps when tested at area 51 prior to flight.

If you think its got not enough power on 4s, i guess give it a whirl on 5s
as long as the motor is ok with 5s
