Here are some nozzles for the Vulcan.

Although this is true, and I actually did bounce back and forth between the two, I will most likely put the AR630 or 631 in this anyhow. Same as what I did in my 'Spekdyn' PT-17. They're just what I know..

The AR630 is a good receiver but you would need to be very careful with locating it to avoid shadowing from the battery pack and EDF unit, since it has no external antenna.

Exhaust nozzles on eBay. 128mph stock vs 147mph with nozzle!

There's something wrong with your links.

Try this:

(Incidentally, that speed increase would require a 32% increase in thrust, which seems very unlikely to me just from adding a nozzle.)

Blues as good as the vulcan is id go eflite viper70 for first jet. Its 19 dollars more but if you are using spektrum it comes with stablization rx

Yeah no weird stuff… here is a pic of where mines balancing, the mold mark in the center of the picture next to the gear plastic mount towards the center line.

Speed… I got to fly it along a friends 8s Avanti and the Vulcan is faster. I am good at speed retention though.

Ok thanks, and yeah- the speed is impressive, even at 1/2 throttle it zips along. It looks like I can shove my batt further back, and I can get CG about 1/2" aft of where it is now. I will have to try that next flight. Come to think of it- I did end up with about 6 or more clicks of up getting it dialed in first flight, so it probably was a bit nose heavy. I'm impressed it beat an 8S Avanti!

Our team developed the Vulcan 70 to offer both an approachable trainer for first time EDF jet pilots....

Alright team, I'm gonna pull the trigger on this statement! This will be my 1st shot into the jet stream of the edf craze.
It's gonna be a blast

Interesting- and I meant to say using HRB 4000 batt. So yeah- 3/4" behind the mark, I would have thought that would be really tail heavy..but apparently it's working really good for you. Maybe I need to try a heavier liperior pack I own.

Decided as I had an extra set of Williams racing theme decals from Callie lying around- why not use them on this jet. Have to say, I just love the profile of this jet, nicer than most of the other sport jets IMO- I know, it's like art, very subjective....

[kallend]

Yes please! Maybe James can go into the parts department and find something like this https://www.motionrc.com/products/fr...zle-fj21111092 and let us know

If someone will provide the OD and ID dimensions of the (unfinished) rear end I can quite quickly create a STL file for a 3D printed nozzle to fit.

I am not that experienced with jets yet but I flew my Vulcan today for the first time. I had three flights with no issues. I found it easy to fly and land.

I'm balanced about 3/4" behind the mark so a lot further back from you. I wonder if that is why we are getting different results.

I did straight stall attempts and couldn't get it to drop a wing and did many high speed vertical snaps which were easy to recover from. I'll try some more tomorrow.

Where are you balancing at?

Hi Evan, I have a HRB all the way back, just slightly nose heavy in regards to called out balance marks. Inverted, it seems to fly just about right, so I'm thinking its not tail heavy. Maybe I should be sure, and put batt a bit more forward, Yes, please let me know if you experience that tomorrow- thanks for reply!

Ok, so I ran 10 batteries through the new vulcan in the last 2 days, and I have to say overall- I really like it. That said, it has the scariest stall/ spin tendencies of any jet I've owned. I did a sort of crazy vertical "snap" thing, idled back, and as it fell nose down, it started to spin violently, one way, then the other, and I fought it hard for several seconds to save it. Odd, I do this maneuver with my bae hawk and Avanti all the time, and its super easy to recover. I did notice there is much less washout than the avanti and hawk, maybe that's the reason? Tomorrow I may take it up really high, and see what happens with a normal power off stall and (hopefully) recovery. Can anyone else who may have flown theirs comment on stall/ recovery?

[Evan D]

Not a bad idea!

[SnoPark]

It's calling out for a nice nozzle on the rear end.
