Hyperion 1913/1919 question

I'm about to get a new motor for my Easy Star, and have set my mind on a Hyperion. I have been looking at the 1913-06 / 1913-08 and at the 1919-04 / 1919-06. I do not need a fast plane, but at plane with a good climb rate and some power to lift my camera.

The 1913-06 seems to be for fast planes and the 1913-08 seems to be for medium fast plane. For my purpose, should I choose the 1913-06 or should the 1913-08 be better ? I will use the 6x4E prop.

I have also been looking at the 1919 serie, which have more power. Again there is a fast-motor and a medium-fast-motor. Not sure what to choose.

It depends on what your battery is. 2 cell lipo? 3 cell lipo? NiMH?

On the Easy Star you are limited by prop diameter so on a 2s lipo I would go for the P1913-06 and on a 3 cell I would go for the P1913-08. Both with the largest diameter prop I could fit.

If I wanted lots of power I would use the P1913-06 with 3s.

I'm a bit confused now, sorry.

Does the 1913-06 has more power with a 3s, than the 1913-08 would do, also with a 3s ?

I'm not sure if I'm going to use 2s or 3s.

Yes, the 1913-06 will draw more current with the same prop than the 1913-08. Take a look at the prop data for the 1913-06 and the 1913-08. It shows lots of things for 2s and 3s batteries with different props.

Check the power you get with say a APC 400 EP 5.5x4.5 which is about the biggest prop you can use:

1913-06 on 2s = 64.4 watts
1913-06 on 3s = 194.3 watts
1913-08 on 2s = not shown - prop too small
1913-08 on 3s = 99.75 watts

For the Easy Star, any motor with a kV between 2000 and 2200 and able to handle 20 amps continuously will haul that camera just fine on a 3s Li-Po and an APC 6x4E prop.

It's the motor of choice for a majority of Easy Star owners looking to upgrade their planes and/or haul cameras.

I personally use an E-Flite Six Series 2000 kV on 3s and the APC 6x4E, but there's nothing special about the E-Flite motor.

Ok, now I start to see how things works together.

There is really a big difference between the power with a 2s or 3s.

I can see that with a 3s, 6x4E and the 1913-06 that the current is 17.8 amps. I'm planning to get a 30A ESC, but would it be enough with a 20A ECS - or have does 17.8 amps nothing to do with the size of the ESC ?

It's always best to have a good bit of headroom with the ESC rating over the actual current drawn. In your case, I would go for the 30 amp and that will be safer now and more useful to you in the future.

If I compare the 1913-06(186watt/17.8amps) with the 1919-04(233watt/21.8amps) - still using a 6x4E prop.
I get a lot more power for not that much money.

Would it still be safe to use a 30amp ESC, with the 1919-04 (21.8amps) ?
and is there a big different between a 1919-04 and 1913-06, mounted on a Easy Star ?

Yes.

The 1919 is a longer motor but it is still a smaller diameter and shorter length than the original speed 400. That should make it easy to mount in a plate glued to the back of the existing motor bulge without the outrunner rubbing on the sides. It should be a nice installation.

233 watts in a Easy Star is a lot! I used to run mine at 180 watts and it got very squirrelly at full power. I would choose the 1919-04 on 3s but maybe prop down a bit. I got very good results with an APC 5.7 x 3 ".049" prop on the original Speed 400. That would give something like 175 watts on this motor but without too much pitch speed.

I'm not going to fly full speed when flying horizontal, I need the power to get a good climb rate, when I have my camera mounted. Would it be possibly to go vertical with 180 watt or with 233 watt ?

Do you know how much watt the original Permax 400/V6 6s NiMH give ?

Just about!

About 50 watts. A bit more on 7 cells. But they are only about 50% efficient so not much gets to the prop. Your outrunner will probably be 70+% efficient.
