    RE: EXI 450 thread

    [&o]went to the park this morning. conditions were perfect. i however was not. after all the excitement yesterday after learning my forward flips i get over confident and CRASH.

    damage report:

    tail boom
    flybar
    main shaft and feathering shaft
    horizontal fin
    main blades
    main gear

    right after the crash i went straight to the LHS for parts.. i now have the entire tail section with trexsev2 parts including: new metal tail gear case and metal tail rotor grips.. the exi head hold up on the crash very well...only the flybar was bent. so no need to replace the head just yet. final costs of new upgraded parts and supplies. 107 bucks!

    got the crash on video and will post soon.

    Awww Noob...bummer...at least you got it out of the way...I still have yet to crash mine. (knocks on wood/crosses fingers and toes/sacrafices small creature to heli gods)
    The fun New Mexico Winds are back in the afternoons...so I did not get to fly at all yesterday...I ran out of time this morning and winds are already up around 15mph so I may not get any in today...tomorrow they are saying 25-30 mph with gusts up to 45mph and that is suppose to last a couple of days. I am hoping it is over by the weekend.

    RE: EXI 450 thread

    since both my blackhawk and exi are down i had to wipe off the dust from the HBK2. its still flys well. tail is locked solid with the esky hh gyro. that was the good ol days where it was easy to fix and tune the HBK2. i may be down but i'm not out. i always have the HBK2 to fly when i need it.

    i finally fixed my exi 450.. it now have the trex tail case and grip. trex tail boom. the only left that is still exi is the frame and head. it was a real pain to change the pinion on it. i just finish the first test flight a little while ago. still have to trim the swash just a little and its ready for another adventure. i will post the pics in a few minutes

    here is the new tail case and boom. i also modded the canopy so some air would help cool the motor.

    RE: EXI 450 thread

    update.

    just installed carbon paddles on my exi 450. so now every blade on it is carbon.

    i also found out why my tracking was off at high rpms. the flybar was bent but it was so hard to tell visually. i thought i had already replace it but i must of forgot during the rebuild. everything is now dead on. i actually prefer the frame to be metal rather than carbon. steel is stronger. i was thinking about upgrading the head to full cnc but didn't think i have to just yet. i took a real good look at the head and it looks fantastic. the only plastic on it was the seesaw and the blade grip.

    i now know how to rebuild it. . which isn't that hard at all. i'm kinda glad that i crash it so it forces me to get to know this awesome heli
    i think i'm ready for the trex kit. it might take me a while but i know what to do,

    i wanted to see if the trex blade grips would fit on my stock exi head. as it turns out it is a direct fit.. this bird is becoming more and more trex.

    RE: EXI 450 thread

    one last ride.

    well looks like my exi 450 is done. crashed it this morning flying around in idle up. sun caught my eye and i lost orientation for a split second. when i saw it again i couldn't tell if its upside down. lol. it came down full throttle and smacked the ground. the entire frame was bent. all the servos survive the crash. those hs65mg are tough! they've been through 3 major crashes in idle up and they are still working flawless. the head was still intact. flybar and feathering shaft is probably bent. the entire tail made it through ok also. [] i was able to get one last vid before the crash. it was flying FANASTIC! so much power. it climbed like it was a rocket. this heli made me appreciate the power of a true 450.

    I went to the LHS after the crash and picked up the trex 450SA. i just finished putting it together with the servos and gyro from the exi. I picked up the align 430XL motor for my new bird. at 3700kv and monster torque. i only spooled it up to see if all my setup was correct. only the intial spinup i goosed it all the way to see what kind of power i'm looking at.[X(]. (this was done on a bench) holy crap this thing is a freaking dynamite. it immediately chewed up the main gear. I replaced the main gear and reseated the motor for a better pinion and main gear mesh. tested it again after adjusting and it sounds beautiful. i also have the hobbywing 40a esc that i think i'll test to see if i can squeeze more power out of the motor.

    anyways this will probably be my last post on the exi 450. it was an awesome ride. i'll post the last vid on youtube later

    RE: EXI 450 thread

    i give my exi one last farewell and disassembled all the parts i might use later. now i have extra bearings and screws.

    I just test flight the trex 450 for the first time today. It is ready. this is my very first 450 build that i put together myself. . took a total of 4 hours from setup to test flight. followed the manual to the letter. the cool part is that the manual was setup with the dx6 in the book. . that made it really easy to setup. i even measured all the links to the exact specifications like the book and sure enough it was perfect. tail is holding perfectly. the only thing i didn't follow by the book was the v curve for idle up. in the book they have it at 100 85 100. i changed to 100 90 100 but may increase it to 100 95 100 for even higher head speed.

    RE: EXI 450 thread

    Hi All,

    Nice to find the thread. So I've had a couple of RTF's in the past and I just ordered an exi 450. I am looking forward to building it up and learning all about the heli as I go. I am hoping someone can point me to or help me compile a complete recommended parts list for the build. I have googled a bit and basically what I've found so far is discussions about what's better between two parts etc... and not often is the exact part number mentioned. I would REALLY appreciate it if I could come up with a comprehensive list in order to avoid ordering incorrectly and having to return etc...

    P.S. I am still very new to cp so 3D is a ways off.

    Thanks in advance,

    Zack

    RE: EXI 450 thread

    Thanks Noob! Is Ar6000 compatible with the dx6i? The exi is on the way and I'm going to start ordering parts. Getting stoked! Would you recommend dissassembling the frame and checking grease and locktite?

    Thanks again!

    RE: EXI 450 thread

    yes the ar6000 is compatible with the dx6i. but since you have a full range transmitter get the full range receiver. I'm stuck with the dx6 at the moment but have been looking at an JR or the dx7 to replace my dx6.

    when i first had it I didn't loctite or grease anything. I just went over all the screws to make sure they were tight. It came with the screws all tight. you'll really like the quality of the heli right off the bat. the only things i didn't like about it was:

    Horizontal and Vertical fins. they were cheap plastic
    Horizontal fin and Knighthead holder. again cheap plastic
    Tail Gear case. not too bad but still all plastic
    main blades. they give you these cheap plastic blades that are HEAVY i have never used them. never even tried to fly with them

    I immediately bought the trexseV2 tail gear case and metal tail rotor grips
    bought the vertical and horizontal fins for the trexsev2
    metal horizontal fin holder
    align 325 pro woodies
    trexsev2 metal blade grip

    here's my replacement for the exi

    i have also decidely to buy the JustGoFly 500th motor for it. i believe this will bring my headspeed somewhere in the 3500 or 3600 rpm.
    from what i understand the 430xl with the 13t is putting 3000rpm. its smooth but i want MORE.

    went to the park this morning and flew 2 packs on the trex450. tail is rock solid. full punchouts without so much as a wiggle. didn't do much as i'm still coping with the lose of the exi. i even had the shakes. i'm sure that will go away as i get more comfortable with it

    RE: EXI 450 thread

    Has anyone bought the exi all aluminum special edition version from Xheli (exi tg 450se)?? If you look closely the head is a slightly different design than a trex. Also the gear is a carbon copy of the Beam and Blackhawk design. It looks really nice. Im also looking at the Beam 450 but the price is high. Im seriously looking at getting the exi aluminum 450, however my only concern is getting replacement parts from xheli or another source. Need some feed back to make a final decision. Thanks all. Sorry to hear you crashed your exi Noob. I crashed my blackhawk yesterday when showing the wifey how I could do backflips and rolls. LOL thats what I get when I say watch this.

    yes i too wanted the tg 450se. and i have the same fears as you when it comes to replacement parts. you cant trust on xheli to provide a flowing staple of available parts. it does looks very nice. i was also looking at the exi 450 pro edition for 199 also. this is compatible with trex 450.

    RE: EXI 450 thread

    i just got my exi finished and am having problems.. i think it is the esc.. when i do punchouts the tail is outta control... it has a gy401 and s9650 servo on the taill. all are brand new.. the esc is a exceed rc volcano series.. it is rated for 40amps but the max current the motor pulls is only 23amps.. the esc gets very hot.

    RE: EXI 450 thread

    the esc might be the problem. i went with the align bl35x esc and it works beautifully. what kind of motor are u using? also when setting it up use the trex 450 instruction manual. i followed exactly to the letter and it flew perfectly. let me know if you want the settings i have for it. i just bought the mars 480 and will now spend much time putting it together and setting it up.

    yea i am thinking the esc is the problem./. the gyro holds the tail rock solid but during punchout the tail is gone (the helis actually does a piro) the motor is an exceed rc alpha 400.. i noticed it is kinda weak also.. sounds like they sold me some junk.. i think i will go with an align motor and esc
