Voodoo and I were talkina about it yesterday. The 1115/1Y is your ticket. You say you can not tell a huge difference between the 2.5 going from 4 to 5 cells. I can tell you honestly I can tell a massive difference going from 4 to 5 cells on the 1y. The 1y is the perfect combo I think.

I pulled out of throttle but still got a glide speed passing the radar gun at 211mph.
Which prop are you using?

1115/2.5D

I was getting 150 degrees on 5S with the 5.25x6.25

This was with 40 second runs with 20 seconds in between.

I would think that at 2800kv, it would be very limited like Voodoo suggested.

We had a very big flyin over here in Georgia and managed to get a high speed pass with the radar gun at 235mph on 5S. Got a real cool picture. We tried to get one of the passes with the numbers showing but the button wasn't pushed on this pass.

235 mph on 5s, the Viper must be really fast

was that with a dive and tailwind?

Yes. Not sure of how much tailwind but probably 5-10. not sure. The same pattern I drew up on the other thread was the same way I flew. I go full power, 45, half roll, pull a big half circle to bleed as little airspeed as possible and then go flat and level. Probably flat and level for about 200 yards out before it passes by the radar gun. This is a max speed run. I dont think I have anymore speed to get than that on 5S. Other passes were clocked at 225 and 226. The 235mph was right off a fresh battery.

Does anybody face hard work when balancing those sets of prop+spinner?
It's so hard to get all these things running smoth, I spent some money buying a bunch of sets and still couldn't find anything that deserve my wow :-(

B plan- anyone flying small carbon foldings? GM ones?

I'm flying my Viper F5D style. 5S, Neu 1115/2.5D, APC 5.25 x 6.25.

Probably nobody will tell you NOT to balance props, but I don't balance mine and never have. I do notice some props run smoother than others - sometimes I get a really "sweet" one and you can tell, but even ones that aren't that great are just fine and don't raise my eyebrow.

Got 110 I think logged fligts on the plane and motor now. Still going strong.

neu motor numbers?

I just dropped in my replacement motor from Neu, 1115/1y/3.2. The amps are down 13-15 and the watts are down 350 from the old motor. What could be the reason behind the drop and how is this going to affect the Vipers performance?

Was it a 1115/1Y you had in it before also? If so, I can tell you I have a 1115/1Y which is too "hot" because of a loose shaft. It will be sent back for repair soon. I expect a drop in amps like yours, but can compensate with a bigger prop if the performance is not satisfactory.
