Default PowerUp 10---Improved Performance?

I have a PowerUp 10 from HeadsUp and am thinking of putting it into my old Parkzone T28. The stock motor---480 960kv---is a 35X33 and weighs 87 grams. The PowerUp 10 is 35X35 and weighs 102 grams. My question---Is it likely, or even possible, that the Power 10 will produce significantly improved performance when the stats are so close? If possible, please explain.
Thanks. Gary

Keep in mind that there is a major storm barreling into their area of Florida. I wouldn't expect a reply from them for many days. That said I just got my 14th order from them yesterday. Love those guys! No matter what they seem to make things happen and ON TIME!!

Bear in mind that the power up 10 comes in two different Kv values, 1000Kv and 1450Kv.

The 1000Kv motor should be a straight replacement and should spin the same size prop, maybe with a modest performance increase. The 1450Kv version would have to run a smaller prop, about 75% of the original prop diameter. Heads-Up have prop tables for their motors which is a good guide.

As with any motor/prop swapping, it's highly recommended to check with a wattmeter to make sure the full throttle current is within motor and ESC limits.

My PowerUp 10 is the 1000kv model. I can't see that it would provide much improvement over the stock motor---35X33 vs 35X35.

The Power-up is slightly higher Kv (1000 vs 960) so if the specs are accurate it will spin the prop slightly faster. Motor power is proportional to RPM^3 so a small difference in RPM makes a relatively large difference in power. If the specs are 100% accurate you could expect to get (1000/960)^3 = 13% more power


So not a whole lot but maybe just about noticable (if the specs are accurate)

Ha,

Why stop there? A group of us have souped up the T-28 with the Powerup 25. I'm running mine with a 60 amp esc on 4S 2700mah 40C lipos. Now before you do this, you need to beef up the airframe. We have added CF spars from arrows. taped up the h-stab. I literally blew mine off once. Hilarious. Talk about "blowing the doors off."

Almost turns the T-28 into a Reno racer. Now if you're really feeling the need for speed, get the Rochobby Strega or Voodoo Reno P-51's ( $200.00 @ MotionRC) and run on 6S with a 10x10 prop. Katie bar the door ! Faster than my fastest edf. Hauls the mail.

The nice thing about the eflight T-28 is that you can build a new one from spare parts for pretty cheap.

Have fun !

Hawk
