So far... So good

Ok, my Rex is back.

I've been dinking with this thing for some time now.

Seems to be working out at this point (knock on wood).

450 X
Align 430L
Align 35
Apex 15c 2100 3Cell
Futaba 401
Futaba 9650
GWS Naro Std (3)

I finally got the Gyro running in HL and I'm lovin' that.

Also did some much needed tweeking on my setup.

hello mate, I know nothing about helis at all, just thought I'd have a little browse in the heli section here. That cf canopy you have looks the nuts!!! Did you make it or buy it?

Well done mate.

Glad to see you are happy with the Trex and got over the GY401 problems (did the other setup have a digital servo, I can't remember). Nice Pics and Heli.

If I'm not mistaken and I don't think I am that is an Align canopy.

I would have put the gyro under the boom or inside the frame. Many reports on it being hit by flybar in that position. MJP makes a nice tray to put it inside the frame.

Glad you all like my bird.

I just got done flyin' here at the house.

I'm happy to say that it's actually left the nest a few times.

Climbed out and flew over the locals down the hill. Hehehe.

The canopy is faux CF. Don't know who makes it but I got it for cheap.

Like... ten bucks.

I solved my gyro problems by taking my original 401 back and exchanging it.


Once I got it going, I picked up the digital servo.

The in-frame gyro mount sounds like a plan. Any more info on it? Pics, website, etc?

Also... what kind of tach do y'all recommend? I'm doing the "by ear" approach here
for the time being and also listening to what the esc and motor are telling me.

Try this hack...

Very OLD pic BUT this is how I run on two Rotorworkz G3 frames and a couple of stock align plastic frames previous to that.

I'm wondering what I'm looking at here.

Of course I see the 401. I'm curious what you have it zip-tied to.

Also, what's the small round thingy on top of the gyro?

NO NO come back...spLAT!!
he made a tray extending from the frame backout to hold the gyro (i think it's alum). That thing on top of gyro looks a low-batt warning device...(micro scream alarm).

My solutions. In the CF frame the rx and battery is in the front and guro in the back. In my V2 the receiver and gyro is in the back. The gyro sits on an MJP gyro tray. Just in case y'all wanted to see a neat home made antenna I put up a pic of mine...

Nice setup tintin. The tray looks clean.

kryptoniteRxn... What all do you know about these battery alarms?

Sounds like a VERY handy thing to have.

Thanks. Highly recommended, have the same on both those Rexes. Very nice product. You can also get download cable to have your Rex's consumption on your pc. Nice people to deal with.

Nice mod Tintin... not an option with the Rotoworkz CF frame as it was missing the 'vents'.

LiPo alarms are a MUST have IMO... I really do not see how you can fly a LiPo powered heli without one and not fry your pack sooner or later.
Apart from telling you when you pack is getting low they also work very well to tell you when things are 'wrong'... so (as per heliman13s thread about battery problems) if you have some kind of issue which causes high current load and the pack sags quickly, or a balance issue with the pack then the LiPo alarm will let you know to stop flying.

These things (the nice ones with a 'siren') are $15 or $20... if they save just one pack from getting toasted then they have more than paid for themselves.

To be honest (and I'm not having a go at anyone here) I'm a little surprised that folks do NOT have these.
