Excellent to know Ron.. same motor basically (SK3 3642) I am getting, but on 5S??!! Likely stick to 4S here. Do you remember the prop and ESC? I am concerned about overamping my 60A plush with too much pitch.
These airbrushes go for inexpensive to very expensive but are excellent for even spray coverage.

Did the stock motor mount work ok with the 15? I'm using the Spitfire motor mount which does align up with the PZ screw holes, it just seems very nose heavy.

I am using the stock motor mount with the Eflite 15. It is heavier but the plane has never gone down and the mount is holding up well to 60 plus flights... everyone with some WOT... or corkscrewing into thin air.
I too have the mentioned aluminum billet mount, but have not gotten to it... I had the motor & mount out as a unit at flight #50 for other repairs and it looked good ~ no sign of stress, so I put it back in. The eflite motor is just a hair long... I mean 1 mm it rubbed the first cowl at high speed only. It had a cut in it from the motor rubbing but you couldn't reproduce the rub on the bench.... I replaced the cowl.($6 painted at the LHS = gotta love PZ)
I modified the new one. I found a 1/4" fender washer fit inside the center flat section. With a bolt attached to the washer, I put the bolt head in the vice so I could pull the cowl away and the washer inside would pull the cowl center out and away from the motor mount area... a little gentle heat with the hairdryer and a gentle pull on the cowl gave me all the extra room I needed for the motor.

Weight wise you will notice a difference. I added 15 oz with the power 15 and the 2200mah 4s batteries. ( satellite receiver & BEC included) She still has great slow flying stability but she lands a little faster.
If you already have all the stuff..... it's a no brainer. Build a hot rod T28

No sorry. To much LSD. But, probably 80A speed controller and something like a 9x7.

I stongly urge everyone thats going to experiment with the drive train to get a watt meter. Saves alot of smoke in the air. Also, blenderm your stab. They will delaminate. Pass it on.

LMAO, always will pass it on. Figured Belderm all leading edges with the speed. Will be adding a thick CF rod of course at the wing as you did, and one at the elevator with the tape.

Interesting experience today... as many of you know used 2 cans of Fusion gloss yellow to get my T-28 shiny and looking good. Will be adding blue very soon (under wings.. hopefully with graphics, under tail, upright stab). Yes, some overspray, etc but was worried about using 24oz of paint on the plane. Running currently stock everything, but Dax's 10x10e APC prop. Takeoff on short grass 30', planes flies perfectly (though did have to move surfaces thru full range of motion due to painting to free up fully). Honestly the plane flies faster.. I was expecting s-l-o-w.. but not at all. I would say as fast, but feels 2-3 mph faster now than before painting. Only thing I can think is a smoother surface (wings and body) .. ie.. less drag compared to raw foam to compensate for the added weight??

Only thing flying the T-28 now that would make me think "heavier" is a notably longer roll-out after touchdown.. maybe 10'-20' longer rolls now.

Weird, and not what I expected.

Ok guys, just need to pick your brains further.

I'm having to order some parts for the T-28, like the prop adapter etc..

Also looking at purchasing the Master airscrew 10x7 3 Blade prop, looks like this should work on on the PZ 15 Motor and the 30 amp esc?

Also looking at the dubro 2 3/4 super lite wheels.

Anything else you recommend?

Very impressive speed and thrust from the big motor. The weight yeah, it is what it is... lots of copper makes a good motor, right?
But you have to use that copper correctly. I've got a hacker a30-12xl in a 51" plane. If I put a 10x5 prop on it it's not going to work as well as the 14x7 or 15x6. Same with your p15, you could go 12x6, or maybe 13x6.5 but the gear limits that. At 950kv that's about as big as you can go. The hacker is a 750kv. For grins one day pull the gear and try that 12" prop. Then you'll see what a lots or copper in that p15 can do!!

I tested the EMP 10x7x3 on the P15 motor with 3s = 360w 32a @ full and 140w at 18a half throttle. It looks like a maximum prop for that motor and esc. The MS prop may pull less amps.

I ran a 10x6x3 GWS too with better battery life... One thing I noticed is no 2 manufacture's blade designs are the same. They vary in width and tip design. All this gives different results. The thinner looking blades will have less drag, pull fewer amps, and pull less air.

How does one order a couple of these mounts? I have T-28 and P-47. I have found stock mount to be one of the few weaks points on these planes, especially flying off grass.

I've got a handful of the basic turnigy 2200s I want to use in this plane. It looks like the square foam extension on the underside of the cockpit is interfering with closing it up with the batter rough installed. Anyone else have to trim that portion of foam off the underside of the cockpit to get it to close over a larger battery?

I eventually did the battery tray mod you find a few pages back.
