Motor upgrades on Soarstar (Wingo / Poppy)

I've been reading for a couple days trying to figure out what would be a good motor upgrade for my Soarstar. I don't see a whole lot of messages regarding this. I read that some Poppys came with Speed 480's.

I have been checking the specs here on hobby-lobbys page, and it would seem the "rocket 400" would be more powerful and about the same price. Or why not shove a 480 Race on there? The Rocket 400 shows 12 for thrust (compared to 8 for the 7.2 volt speed 400) I understand the current draw is higher therefore a shorter flight, but the price you pay

Im sure people here have already tried some of these motors, interested on how they worked out. I will be using it with a Soarstar, which already has alot of juice, but when I am carrying my wireless video equip it would be nice to have some more power.

I have some Rocket motors !

They spin fast !

You will not need full throttle all the time, so flight times can be extended with proper use of the throttle stick !
______________________________________________

The Ultimate upgrade for a Wingo-type, would, in my opinion, be a Hacker B20-26L.
( I have one on order ! )

On a seven-cell 500AR pack, with the Gunther prop, this will put out 10.6oz of static thrust, and rpm will be in the order of 14,700 - for a full throttle duration of 4-1/2 minutes ! Pitch Speed would be 55mph ! Current - only 6.5Amps !

Expensive though - you'll need a sensorless ESC too !

Can you suggest a place to order those goods?
What is a sensorless ESC?
I'll start doing a search for those items...
Maybe I'll grab a Rocket motor for now. Surprised there arent more threads about 'em.

Thanks for the info

Hacker Motors in the US

Joemi,

Take a look at this page:

http://www.aero-model.com/planes/hac.../b20series.htm

Or the German Home page -

http://www.hacker-motor.com/

Certain variations of the B20 motors can be swapped as direct replacements for S400 motors.

My E-Boomerang is to be treated with the installation of the B20-26L motor, as soon as it arrives !

The motor will be used in various other own-designs that I will be making throughout the year as well !

Send Sean a mail, ( adress on the Aero-model home page ) and see what he has.

You will need a special ESC to control brushless motors, a Jeti JES18-3P, or a Schulze Future 18be would be the ideal.
I have a Schulze Future 45be, so I'm ok !

I'm sure that he will advise you.

WOW! You werent joking when you said they were expensive!
Now that I've gotten all excited for it, I just can't afford it
Would love to hear how your hacker motor turns out when you receive it and take her for a flight!

Have you considred the Dymond 480/48?

I think Mutltplex calls it a 450.

Its longer than a standard 380/S400 and have been a good zagi upgrade.


Don't think I'd consider the Rocket, cheap and a bit more speed on a Zagi, but short lived.

An S480 is a bit over the top as well.

Use a s400/6V mated to a 2ish:1 ratio GB and 7x7 or 8x6 prop fed by 8 Sanyo Twicell1700mAh NiHM. No need to use a new ESC and flighttimes should exceed 15-20 minutes.

I agree with Haldor.

On the Wingo there is too much drag to throw in another motor.

I fly Speed400 6V, 8x500AR packs, 2.33:1 (will try 1.85:1) GB and 9x5 or 8x6 prop, both great.

Why do you want a new motor?

If that question was directed at me, it was becuase I thought my motor was dying and wanted to upgrade while i was at it, but it turns out, I think its my speed controller that is flakeing out on me.

I am using a reverse rotation s480 with a 5.5x4.5 cam prop running on eight cells and am able to carry an autowind camera or take off on floats with ease. It is the set up that hobby-lobby sells in pairs as an upgrade for the starjet.

Joe, I'm sure you've thought of this, but hook your motor directly to the nicad and bypass your SC and you will know if your motor is crapping out.
