That would put you at around 1050 Watts. Phoenix 80 would be needed.

A D99 could take it.

How fast do you think I should get out of it with the above setup?

I can't say.

But I just found this.....

"My d99 which is smaller and very slippery compared to F5D does 140 level on just over 500 watts. 200mph would require a theoretical 1000 watts but that's in a d99 which is tiny 1000 watts would be hard to squeeze into the airframe since it's so tight on space. "

So...that setup would theoretically get you 200mph, but you would need to get a 4S 2450 in the fuse at minimum to handle the amps. Probably not going to happen. 750 watts should be doable with a 4S 2200 if it will fit.

Figure 170ish type speed. Prop down with the same motor.

i.e., the slowest, lowest amp draw config that will still fly this thing well and still give you an entry level feel for this type of plane.

Not looking for an entry level feel.

I would go with the stock setup and prop down to a 4.1x4.1.

If you want cheap, go with the Turnigy 2835 2700kv on a 4.1x4.1.

Im going to test both 2cells (30c) with 7x4, 6x5, 5.5x5, and 4cells with 4.1x4.1 and 4.5x4.1 on the recommended esc and motor. Keep posted

do you have good experiance with the Turnigy 2835 motors?

I'm interested in this new Rifle. I have a new Turnigy 2835 2700kv and was wondering if I would be better off using it with maybe a 5x5, or spending the extra money and go with the recommended set up.

Edit: I just watched a video with the Turnigy and it seems to be a dog. I think I'll go with the stock setup for now.

--My beginner pylon setup:

ARC 28-37-2.5 2800kv
CC 35 or 45
4.75x4.75
Hobby Partz Blue lipo 2200 3s 30c

Any guess on top end speed?

Depending on the plane I would guess around 80.

The Rifle will be my first pylon. I'm used to going over 100 with my slope planes but they are much bigger. If I could get at least 80 with such a small plane I think I would be satisfied for now.

With the Rifle I would guess close to 100 mph based on this:

I would say a 5x5 on that turnigy should get you about the same speed as the stock setup.

Thanks for your input. It would be nice if i could find a home for this motor. All my electric planes so far are out runners geared more towards aerobatics than speed. I must admit though my higher priced Hacker motors are much better than the Turnigy, so I can see the justification for spending more money on a good motor. But for now I just want to get in cheap and see if I like fast little planes.

So maybe this would be a good motor on 4s with a 4.1 x 4.1 when there was a need for speed.

Yup. With that prop you'll probably pull around 30 amps, which shouldn't be a problem with the 37-2.5.

Both done with :

Rhino 1550mah 30C
APC 4.1x4.1

ARC 28-37-2

Amps 35
Watts 396

Turnigy 2835-3900kv

Amps 31
Watts 348

After two 3-4 second bursts and initial #'s, I ran both wide open on fresh batteries for 10 seconds. The Turnigy motor was a lot hotter than the ARC.

Based on the numbers, the ARC will start with a 4.1x4.1 in the Rifle. I think this will be PLENTY for this airframe. I remember the ARC getting pretty hot on a 4.5x4.5 last time I ran it in a bigger pylon.
