First Foray into the World of Electrics
Yep, going to give the little Furion a "whirl". As I'm not too familiar with this tiny electric stuff yet, I have a couple of questions.

Regarding the Scorpion motors that have been recommended in this thread, what are the performance differences between the 2221-6 and 2221-8 motors?

I already have a set of three Futaba 3153 micros, do they provide enough torque (19 oz./in. @ 4.8V) to do a good job of controlling the swash? I like the specs of the 3156 quite a bit better, but not sure if it makes sense to spend the money.

Thanks in advance for the help!

Got mine just this afternoon, hopefully have it all up and running by next weekend, life permitting!...Once upon a time there were Nitros, flybars and frequency pins...

Petmotel,

The 2221-6 (KV 4400) will provide a 3200 HS with the 11T pinion. Try to find a smaller pinion in 1/8" shaft size. You're basically stuck with a minimum HS of 3200 with the 2221-6. Even a 12T pinion will push the limits of a 2500 mAh, 3S battery. The 13T pinion in the Furion kit is unusable with the -6.

You can vary the HS more with the 2221-8 (KV 3595). You could even push it to 3500 with a 4S setup and use a 45A ESC.

The 2221-8 is more flexible. Both will give great performance when properly setup. I got the -6, but now wish I got the -8.

using that motor is not an issue, run a good esc like a Kontronik Jazz 40-6-18 and govern it to the headspeed you like....Once upon a time there were Nitros, flybars and frequency pins...

The -8 motor will give you over 3K on the head with the 13 tooth pinion. Works great and will work with the Scorpion 45 amp ESC, but more is a little better. What you will find as you go up in ESC,you can go back to back to back flight wise without any issues. I have found that after 2 hard flights back to back, the 45 gets a little warm and starts shutting down. Not an issue now as I am trying one of the new 60 amp ESC's from Scorpion. Now the ESC is cool and the motor is starting to warm a little, providing a little more power now that it is working harder.

As far as servos, the 3156's are the way to go digital wise as long as you don't get spooked by the weak looking (but works fine) servo arms. If that has you concerned, go with the Hitec 65MG's and they work great too. I have Hitec's on one and the 3156's on another and can't tell much of a difference.

The 9257 is perfect for the 401 gyro.
Running all of this on a FlightPower EvoLite 2500 will get you around 5-5 1/2 minutes of flight time.

Jeeez they make this alot of work this little kit, I could build 2 full size logos in the time its going to take to build this little bugger . It all looks to be good quality but I could see a begginer giving up easily, just in comparison to say a 450 rex and such, it's alot of work to say the least. I'll get it done no doubt but to be honest it's alot more involved than I expected for sure....Once upon a time there were Nitros, flybars and frequency pins...

It should only take about 4-5 hours to build. Easiest way is to lay out the parts for the particular step in the instructions as they are layed out in exploded view. Then just put them together. The only issues I found was the smaller size screws, bolts and nuts. It's a bitch when you get old and can't see them.Team Synergy/Rail, Team Scorpion, YS Engines, VelTye

I must have missed something. My main gear moves up and down a few mm. Is there a wash that sits above or below the main gear on the one way shaft ?

eyefly, did you finish building the grips by installing the carbon, bell hiller mounts, and all the screws yet? If not, once you tighten all the screws with everything attached the grip should free up.

I don't have a kit yet but I wouldn't expect them to be hard to find seeing that Tower Hobbies carries them. Which is awesome because I get their stuff in 2 days with std shipping!!!It's a complex, costly, glow powered anti-gravity machine!

The Boom, main gear, flybar,main shaft are easier to swap than the trex 450. I suspect the fly bar will be more of a pain in the ars. You have to take the grips off which are an additonal 10 screws on each side. This is one part of the design I am not crazy about. It is pretty neet from an engineering standpoint but not form a practical one.
