E-flite Habu STS vs Habu SS! Battle of the 4s and 6s power!

Finally got to take the two of them up together and have some fun! Honestly, pretty close in performance overall but that 6s expectedly has the edge. Enjoy!

[@davidgerlach1132]

Very nice! I like the simplicity of this EDF. It looks like a very nice 1st jet, but the Eflight Viper 70mm also looks interesting which makes it a tough decision.

[@Jeffroe111]

It's a great first jet! The size, weight, and simplicity, make this one easy to grab and go. The 70mm Viper is one of my favorites if you want something a little more complex. It's heavier and lands faster, but if you like something with flaps and retracts, can't beat the Viper. I have plenty of Viper videos, check em out!

[@davidgerlach1132]

@@Jeffroe111 Very good! I'm a checking out your videos... no question, I like the Viper 70mm.

Question: Is the main wing the exact same size between the two models? I know the SS wing has some more carbon supports but otherwise, aren't the wings identical?

[@Jeffroe111]

Far as I can tell and based on the specs in the manuals, they are identical.

I have 1 6s jet (Rafale) & love it. Even tho its been up 3x. Looking for a 4s, 70mm something. STS, using 4s/2700 smart packs, what would you think flight time would be? (Getting 3 1/2 minutes on my raf using 6s/5000 oynx packs)

[@old-rcplane-phart]

HAD the umx & 64mm (& smaller) 'jets' & im not a fan.

[@Jeffroe111]

We have our timer set at 5 minutes I believe for the 4S on the STS and I think we've flown it longer than that if you're not going all out full throttle the whole time.

[@justinwhitehead7767]

Nice! I have the STS Tempted to pull the cord on the SS. What is a budget friendly 6s battery you might suggest possibly?

[@Jeffroe111]

We've been using Roaring Top 4300mAh 6s and they've worked well in all our 6s EDFs.

@@Jeffroe111 thanks a bunch!

[@happymcslappy3640]

Question for you jeffro. Are the battery bays the same size? Can we use a 4s in the SS and upgrade the STS to 6s?

[@Jeffroe111]

Greetings! The battery bays in the fuselage are the same, however the hatches are different. There's an extra piece of foam on the STS hatch that won't close if you put a 6S size battery in it unless you cut it off and you'll have to install a 6S compatible motor. The SS is already designed to take a 4S but for me I found the weight and balance was pretty far off the recommended CG mark and the heavier 6S battery was the way to go to get the CG on. Hope this helps!

[@stefannieuwoudt534]

I have a 70amp esc in mine. One of the first habu. Can i use a 6s lipo in mine or will it burn the motor?

[@Jeffroe111]

If it's an early, all stock, Habu STS, stick with the manufacturer recommendations and don't exceed the 4s. Based on my speed runs, not much difference anyway. We accidentally (just wasn't paying attention because the connector was the same) hooked up a 6s to a 4s twin prop once and the voltage instantly burned one of esc's and motor. So according to my engineer father, the voltage of a 6s would run the motor hotter and faster than it should and likely burn it out and/or blow it up!

[@proudneanderthal1843]

Maiden flight on my SS this morning. I 'm not thrilled with a 4000 4s 60c . Stalls on climb and is pretty slow for a jet. I wish I had a 6s to fly it just to see the difference.

[@Jeffroe111]

I didn't even bother with the 4s cause I was having weight and balance issues and I figured it'd probably do something like what you just described. Definitely invest in a couple 6s batteries you'll appreciate it much more!

[@proudneanderthal1843]

@@Jeffroe111 My buddy described it as a lead turd on the 4s 😂😂. What is the best mah and c rating to aim for?

[@proudneanderthal1843]

Sorry.. just read deeper in the thread.. Roaring top. Got it!

[@Jeffroe111]

@@proudneanderthal1843 the roaring tops have been good for us. Sometimes with the smart stuff that's expecting a spektrum battery you get goofy alarms and voltage crap but they're a little bit cheaper and we've got a bunch of them. Haven't had any issues.

[@Jeffroe111]

@@proudneanderthal1843 we've been using the RoaringTop 4300mAh 35c in our numerous 6s airplanes and have been very pleased. We have a Spektrum 4000mAh 50c pack that has worked well too.

[@aragorn318]

Will there be overheating issues if I run five 4s packs in a row without rest for the STS?

[@Jeffroe111]

Great question. We probably ran 3 packs atleast without rest, only heat I've noticed was from the battery. Everything else was good.

[@aragorn318]

@@Jeffroe111 Thanks. I just got back from running through 4 4s packs without rest and all good.
