I dont know what happened, but I'm thinking about goung FBL on my Trex250. Abit of a joke really, as I have never in my struggeled as much with any heli as I have the 250. The tail on it has been various degress of shitty, crazy wagging resulting in crashes from even forward flying, to where it at today where the tail will slip maybe 30 degress during fast climbouts before it resenters. Like it it today, I can atleast fly it and do some basic stuff like flipping, flying inverted and suchs. I have not dared to push it much harder than this indoor yet, but I would not be surprised if a tic-toc brought it down pretty quick. I have rebult the tail maybe 5-6 times, tried weight mode and 2-3 new tailrotos.

Anyway, I was wondering if I should try the Microbeast and see how it fairs with that. I', currently running the 401 gyro with a DS290 tailservo, but a Microbeats might open up the possibility of using a bigger servo like the 9257?

All thats needed for going Flybarless is a headconversion like this: http://www.century-rc.com/ecs/produc...47&kind_id=718
And ofcourse a Microbeast unit?

Is this just silly and a waist of money seeing as I never could get the damned thing to fly straight to beginwith, or does it make some sence? I have no problem flying it once everythings working, but the tail has always been a big issue for me.

Many people are running the BEAST X in their 250, with great success.
I am running the BEASTX with the 3G head, seems to be the most popular head when going FBL on a 250. I tried the FBL conversion from Mikado and didn't like it one bit.
The BEAST X fits perfect in between the frames, and you don't need to run a RX, just get the BEASTX Sat RX adapter...

ALL has been working great for me.

OH yeah check out the Official Response from Align re-guarding tail issues with the 250. in this thread.

I think you should try and fix all of the problems that you are having with the tail before you convert over to fbl. Why chase problems later when you can fix them now. Im sure the beastx is a good fll unit but I dont thik I will magically fix yor tail issues.

OCFly · 03-21-2011, 01:00 PM

Nexgen just built my MicroBeast FBL Trex 250 along with a FBL Gaui 200. I am really loving the 250 FBL.

There's slight drift that I am trying to dial out but the tail on my 250 is ROCK SOLID. No issues..

FurryTrex · 03-21-2011, 04:12 PM

Did you talk to assuranceRC about a replacement tail HUB. Align issued a recall, if you will, should help alot of people out with their tail issues.

This is true. The MB did not fix my tail problems. In the end I wound up with a FBL 250 that wagged worse than it did before it was flybarless. I'm sure it was my issue; however, slapping a FBL unit on it definitely didn't make it any easier.

Got a vbar on my 250 - I never got the tail to work consistently before, but it seems to be fixed just like that. Previously, with the Align gyro, I could get it to hold without twitching, but the gain was so sensitive that even as the battery ran down and the headspeed changed, the ideal gain setting would change. It's much more robust now.

CHIEF-X · 03-22-2011, 09:01 PM

heres what i have on tap for my trex 250 beasx project.

beastx with dsm2 satelite
scorpion 2206-3900 kv motor
phoenix 25 esc
align ds410m servos
FULL MICROHELI PRO TAIL SETUP
CARBON FIBRE SERVO ROD
JRDS290G SERVO

will all this stuff work in harmony? did i choose the right things for a good heli? dont be afraid to comment and i would totally love any tips or advice as specially on tail setup and phoenix 25 esc. is this a good esc and bec combo for the trex 250 or do i still need a bec cause i got one on my old align bl15x esc. witch one should i use for better performance? i think the phoenix is a better choice for mounting but as far as programing im lost. i think i can make it through the confuseing mess i just dont know what parameters to put in. please help.
thanks for all helifreaks... i love this site

BTB · 03-22-2011, 09:25 PM

I would recomend using a mini size servo on the 250. I didnt like the 290g at all as soon as I started doing more than hovering the servo started to crap out. There are tons of guys using the cc25 in the 250 forum so setup help should not be a issue, If you have any problems just ask and your fellow freaks will answer. I think you should add these things to your finish off your build list. Good luck with your conversion

the Scorpion 3900 and CC 25 is a good match IMO. Tail issues are the major issue with the 250, I had some wag and was able to reduce it with some mods to the tail linkage and CNC parts. it is solid typically but started a slow wag recently. I just installed the beastx on it thus I have not finished setting it up (waiting on the sat adapter). SO we shall see if that resolves the wag or not.

My 250 uses the DS410 & DS420 servo's. Take alook at my pictures for my 250 and how it was and is setup today,

hydev · 03-24-2011, 07:39 AM

get the tail working properly before you fit the BeastX. Just my 2 cents..

Starcruiser · 03-24-2011, 08:30 AM

it was, then developed a slight wag, not sure if it was binding or something else.

felborn · 04-25-2011, 02:09 PM

Well, lets dust of this. I decided to try the BeastX on the 250 instead of the 450, and it really seems like the right choice. The 250 is actually enjoable now, and I have done things like tic-tocs, funnels and inverted backwards flying, things that was NOT a option running the 401 gyro. There are still some issues, but thats down the the horrible Align tail and no electronic is gonna fix that, but atleast now I can actually enjoy flying the little thing again, and actually use it for something more usefull that just basic hovering training which was pretty much what it could handle before the BeastX
