OH... SMEG... Just melted a huge hole in the body of the DragonFly I'm doing... frik'n not pay'n attention... I'll see if I can post a pic a bit later for some suggestions on how to fix the thumb sized hole on the top of the body... just before the riser that covers the swash...
Its really thin on the top and it just dropped out pretty much... I was using a small torch deal with an attachment for cutting styrene etc... I was starting to cut out various things and was making openings on the front of the riser when I got the torch a tad to close... Smeg....
Any ideas??? Should I cut it out and try to glue another piece in?? Glue another piece directly over the whole top?? Under it and fill with 'bondo'??? not sure which way to go or if there is something better...
happy frik'n hole fix'n...

RE: EXI-450 discussions/mods/scale projects
Yeah....the pre-mades have resistors on one of the legs of the LED. Most LED's even the highbrites run on 3v so unless you got too many in series, the brightness should be right. You should wire them paralell and use a resistor on each (1/8th watt, but I forget how many ohms). Dont get too upset if you fry a couple messing with it...I have from time to time.
Can someone decipher this for me....I am not sure how many volts that Dynam BEC is supplying...that could be my problem right there...

That means that if you run 12 cells you can only run 3 servos. On that type of bec the more voltage that you put into it the less amps that it can supply without overheating. This is why a switch mode bec is usually required when you go over 12 volts from the battery.

Well....you just taught me a lesson (LMAO). I run a spektrum 2.4 DX7, and I've had a brownout or two.....it's NOT fun. That's why I'm going to the UBEC on the RX. Thanks for the INFO!!!

I'm thinking the brownouts you've experienced are from too long a run time on your batts? Even if they aren't,an external bec seems to be highly recommended.I've never had a brownout except from too many beers

RE: EXI-450 discussions/mods/scale projects
Hello, I have an EXI-450 and had to purchase a TX and found a Futaba 6EXHP, the Heli has some cheap servos that came with it which are the TowerPro 9g's and I found a Futaba S3157 Digital servo for the tail. It also has an Align RCE600 Gyro and Align BEC35A speed controller. Well Im relitively new to the RC world of Heli flight, and one day I happened to be looking over the settings on the TX and accidently hit the reset button and now all of the settings on the TX are GONE, ooooooSH***, I seached all through the other channels and nothing, it appears that it is now at factory settings and I have No Idea where to begin on any of the levels. I can get thru the settings on the manual ok, it's just now I have no basic setup settings to start from. Are there any of you guys that may be able to HELP? ? ? ? I Talked to the guy's here in town at the E-Flight extravaganza at Century 2 Expo Hall, Killer Exibit and they had reffered me to this Site for help so here I am.
Thanks

Vic I've had really good luck with the emax esc's.I've got two 35a and they do run cool.I'm also running ebecs (1.5a/5v).The ebec's aren't heavy enough to handle 4 digitals though.If you have to replace a esc ya might want to consider the emax.

Hey MCRinc...Do you just want the numbers for our swash mix, pitch/throttle curves for a good place to start? If that's what you are looking for, I would be happy to post all of my numbers for you off my DX6i...If you want specific instruction on how to run that radio, I can't help....

RE: EXI-450 discussions/mods/scale projects
Comments about spektrum are true....I too run a DX7. LohChief runs a 6EXH I believe. To be honest....I had a DX6, went to the DX7....totally different and it actually took a few days to get it so it would even operate correctly, and took MONTHS to fine tune it. Wish we could help here, but that's how it normally goes with "non standard" systems. Futaba is a GOOD radio system, I've had several on planks (the old days). I personally chose DX7 because it's a common choice for the T-Rex, and the programming is nearly identicle with the EXI-450, and LOTS of people have the DX7. Sorry dude.....[:@]

The Hobbywings are nice, very efficient. I bought one with the built in BEC because the 40A series actually has SWITCH becs in them. I can fly 4 packs and it gets only 5-10 degrees over ambient temps.

I have a Futaba 7chp for my EXI but I haven't began to set it up yet. If you don't have your's straightened out before I get started on mine we can share info. then. Otherwise it's just about getting the manual out and working through the steps.

RE: EXI-450 discussions/mods/scale projects
Start with settings recommended by Finless Bob @ Helifreak for Trex 450.
I used them to set up my RDS8000 for the first time.
Worked out really well for me.
The throttle and pitch curve settings are pretty much just a matter of plugging in numbers. Fine tune to suite your needs.
The only settings that require a bit of fussing with would be the servo center positions at 1/2 stick. These settings are based on the mechanics of your particular model.

RE: EXI-450 discussions/mods/scale projects
The basic settings should be the same for most radios, Swash type etc but when you get down to things like servo direction it depends on the brand of servo, installation and other things so you just have to get into the thing and go through the settings one at a time.

RE: EXI-450 discussions/mods/scale projects
OK...I got the stuff in today, it's installed and I've done a few test hovers. Heat prob is gone...that's the good news. For some time, I've been having a tail indexing glitch...annoying but not crucial for me. Well...I installed the 4 E-Sky digitals and the rudder servo being digital ratted out the problem for me. The TELEBEE gyro is causing the glitching, and this is the second telebee I've had that's been BAD in less than 6 months.....I'm done with Telebee. Initial on the E-Sky digitals....they're quick, solid hold, and responsive. I'll follow up as time goes on because I NEVER take things at face value anymore. I need to put these digitals through their paces first. I did install the UBEC also....we'll see how that goes.

RE: EXI-450 discussions/mods/scale projects
i got my xmhobbies g401b gyro today.. gonna try using it with a hs55 type servo.. its speed is [email protected].. gonna run it at 6v so i will see how that works... i am also using the alpha 400 motor ( it draws a max of 23a) for longer flight times.. using a align 35a esc, a ebec, and not sure on what cyclic servos yet.. hopefully the gyro/servo setup holds the tail fairly decent. i am using all of this with the spektrum radio.. not gonna 3d this bird, just wanted to build one that is a lot easier on the lipos and has longer flight times... i also left the flybar weights on for more stability ( i removed them on my other 450's) it may be a while until the build is complete but thats ok. kinda fun to build these things and test different electronics.. the reviews on this gyro seem to be good. not bad for 40 bucks to the door anyway.. i was thinking about just forking out the dough and geting the 65mg's for the cyclic.. would be better in the long run.. i do have one of the older esky 8g servos (non digital) that i saved from my hbk2 collection.. maybe it would be better to use on the tail,. thats just something i will have to tinker with.. trying to keep this bird a little lighter also..

Did you happen to inspect the wires that exit the Telebee to see if they are fraying? I was having similar problems and found that those wires were all exposed from their sleeves and touching each other. I did a little fixey-poo and it fixed the problem. I still know that I fly better than my Telebee will allow, but it's still working well enough to hold the tail as long as i don't try and get too crazy with the sticks.
Let us know Shee if that XM Gyro is worth it. Maybe I will buy myself another present...
Peace on...well, whatever planet you guys are from!
