Inspired by Corrados auto video I decided to post up the latest with theT-Rex. These Sab blades totally changed the feel.


I didn't go into a full routine due to the tail belt teeth being rounded off. Hard collective hits cause wagging and then slipping. This can be bad in a small area

Tonight I bolted on Align grips + Sparrow Products CNC head. Once the new belt gets here I'll get some better footage up with all the upgrades

Great autos! I have something to strive for when I get my TRex together...thanks for the demos!

PS: From the look of the neighborhood, I'd say you don't live too far from me.

Great video! By the way what kind of battery are you running? 3s 4s 5s or 6s. My guess would be the 6s. Anyway How long do your bats last? What temp do they run at? What kind of setup are you running motor, esc, Bec. ext. If you could post back It would be great. I just want to see what kind of set up can make that many hourses. lol. Wow supper powerful.

GrayBug,

Yeah, we're pretty close. I'm over in Palm Beach.


Showerstopper,

I list the power system at the end of the video. I also run a SBEC(not listed in video). Flight times are around 10 minutes I guess? never really time it. Pack temps are high 130's if I fly it all the way down. If I land a little early 120-125 deg. Mega is 155-165 deg.


Thanks for all the positive feedback. Hopefully my final setup comes together in the next few weeks (Corrado, where is my frame!)

Autorotation, shut down the motor and glide it in using collective management to keep speed in the head until you flare. Then you use the inertia in the blades to cushion the landing. Very hard to do with the light wood blades on the T-Rex since they don't store much energy.

how to auto :)
if the motor dies,.. let say 80ft... do you have to set your blades into full negative pitch then switch it to positive before it touches the ground?

ChrisT88,

HA! Our neighborhoods must have been done by the same developer--identicle down to the same mailboxes!

Since you have the extended boom upgrade, what major flying performance/handling differences have you found between that and the regular length boom?

Tomi,

Yeah, I do got a little. I was playing with the gain trying to get my tail to hold correctly when I figured out it was the belt slipping and not a gyro issue. My belt should be here tomorrow and all will be back to normal. Things should be even better back there once my heliup pitch lever arrives


Pinoy_zoom,


The rotorblades would come to a complete stop with full negative. I drop the collective to negative 3-5 degrees and listen to the blades from there. If they speed up I know the collectives right, if they slow I add more negative and get ready to bail out! lol.


Graybug,

The best upgrade so far has been the Sab 320mm blades. You'll need to buy the XL upgrade to fly these blades. I wouldn't purchase the XL upgrade otherwise. The next best thing is the stock 315 woodies. I run the Align cnc washout and SF mixers also.

ChrisT88,

Pardon my "newbie" questions, but my TRex (450x) kit came with 315mm woodies and 325mm carbons--why would they include the longer blades if I need the stretch tail to fly them? Are big blades on a stock TRex okay for hover/sport flying, but a no-no for 3D? (I'm a LONG way from 3D flying!)

Graybug,

I've heard you can fly the 325's without the XL kit if you're just sport flying. I've never tested it, just went strait for the upgrade.


Honestly if you're still a newbie the T-REX stock will take you all the way to some pretty hard 3D. I would focus on learning to set the bird up well and maybe a better power system down the road. The eCCPM T-Rex XL kit should be a very nice flying machine too when it's released next month.
