Trex 500 Build Videos

[Pinecone]

But the big advantage is, I can buy 401s for under $100 used. :)

Jeremy.... after flying the 760 I can tell you for sure it BLOWS away the 401. I don't know that I will be good enough a pilot to be able to tell the difference between that and a Zero-G.



Bob

Zero-G Gyro LOL , It should rock on a Solig G Raptor conv. JK.

epc2.

Ooops.... got me... I meant Solid-G gyro.....
OK OK... It was late last night ;)

A BUNCH more videos just posted.

Head, main gear, etc install

Geometry explained!

Head setup. THis also shows how i set 0 pitch without a pitch guage!

So Bob ,

What gyro will YOU actually be using on this heli ???


Antony.

[Finless]

Curtis Solid-G and 9257 tail servo.

Hey Bob, i've got a Li-Po sitting here, it is from maxamps, http://www.maxamps.com/proddetail.php?prod=Lipo-3000-148-Pack&cat=14, I know 4s but i just want to use it for the first couple flights until i get enough $$$ for a flight power 6s pack, will it fit under the canopy and will it balance well?
Thanks ALOT! :)

[Finless]

It's a little long but yes I think it will fit.

Good Morning Bob,

I use a 4s 1800 & 4s 2170 packs on my Mini-Titan. Would it be posibble to make this a 8s bird with the supplied ESC and Motor or do I need to buy my own?

[Finless]

Nope.... ESC and motor wont support 8S.

Thanks again Bob!!! :thumbup:

Step 11 is up.... Tail drive and boom install!

As you command Bob,

I did a little bit of math to show the effect of using any horn length that results in a different angle than 90degrees. I didn't however figure out the best angle as it gets really complicated really fast.

As you can see even if you let the Lo term go to zero the swash relation to the servo angle is FAR from linear.

[Finless]

Well beyond me dude.... I use to love geometry in High School as it was one of my favorite subjects but after 30 years of rarely using it at this level it's all LOST in my gray matter somewhere....

Splain it in layman terms ;)

Bob

[Finless]

Two more up!

Step 12 and 13.....

Getting closer :)

[th3tick]

Stupid question time: on the thrust bearings, what's the purpose of the inner race being loose? Is it to accommodate wobble without binding against the shaft?

[Locktite]

I am stuck between going with the Hitec's 5245mg's or the JR 3400g..I really want to go metal gear but dont want to suffer on performance..What to do??

[Locktite]

Looks like i am pretty much set on 5245mg's

[spencer737]

what about the futaba 9257?!

[Locktite]

I would rather suffer just a tad in performance so I don't have to change servo gears all the time if i crash..

[Finless]

The 9257's will absolutely give you faster cyclic response. They are quicker than the 5245MG. But as other said including me the servos being direct to the swash means gear strips in a crash and I don't want that hassle.

Also for those looking at 3400G's Only the output gear is metal! The rest of the gears are nylon so they DO strip.

Bob

[Finless]

Well looks like I AM going to finish and fly it tomorrow!!!!......
I got the ESC setup, motor install, Solid G gyro setup for both stick and G-view, and electronics install ALL DONE TONIGHT!

I am compressing video like mad right now man...

Tomorrow AM I shoot landing gear and boom struts and I AM DONE BABY!

I have NEVER shot this much video in one day!

Bob

[Locktite]

Very nice..I may have missed it in another post but what battery are you going to use for now...

[fireup]

ALLLL RIGHT!!:thumbup:

See you tomorrow then.

What motor pinion should I use for a 4s1p 14.8v 2200mAh 25C Lipo Battery setup for aerobatic flying?
