New guy with a new heli
How's it going everyone.. just wanted to introduce myself. My name is Steve and I just finished putting together my first heli:

EXI 450 frame
Align 325 Pro wood blades
Align 430XL
Align BL35G ESC
Futaba GY401
Futabe 3107 cyclic/tail
EVO Flight Power 2170mAh lipo
Spektrum DX7 w/6100

I have absolutely no real heli experience, but I caught the bug flying the little Airhog Havoc Helis with my nephew and now three months later here we are

I put the whole thing together using advise from a guy at work that is into helis and watching all of the Finless videos probably at least 2 or 3 times each

I went through 3 packs yesterday and never got the balls to take it off the ground, just floated it along with the training wheels. The tail is locked while floating along the ground, but it wants to drift to the left. In order to get it to stay in front of me, I have to trim the right cyclic almost halfway through the range (doesn't seem right to me).

Am I worrying too much about this? I'm hoping that it's acting like this because it's still on the ground in it's own downwash and it won't drift as much once I actually put it in the air.

Also, I have been practicing with my DX7 hooked into the computer and using the free sim 'HeliSimRC'. I can actually fly pretty good in the sim, but I need to man up and just put the real heli in the air.

Any comments or advise would be appreciated. Let me know if you see anything wrong with my build. I have thick skin and can take some critisism so let's hear it.

Looks great.

You really need to take the heli up in the air and not let it drift around in the ground. It is hard to predict if the heli is trim right or something is wrong. If you don't have the confident to bring it up, as your friend to at least test flight it to make sure it is airworthly.

If you can hover steady on the sim without crashing, you should have no problem with your heli. Grow some balls and just do it.

Welcome Steve and good luck. You are officially hooked to this hobby.

I wouldn't worry too much about having to trim it. It may or may not be the same trim in the air but either way, you can expect to need a little trimming anyway. Start working on the low hovers and have some fun.

Hi Steve
welcome to RR , here is a link to Radd's school of flight , you will see the list of lessons on the left , a lot of people have used it to teach themselves how to fly

http://www.dream-models.com/eco/flying-index.html

also here is a link to RaptorTechnique that will answer lots of setup questions for you

http://www.raptortechnique.com/

once you are able to get it off the ground about two feet you will see it handles a lot better , also it just takes some time to get used to what the heli does with your inputs , and it will start to come naturally with some practice

FROM WHAT i UNDERSTAND ALL HELIS WILL TAKE OFF LIKE THAT. iT IS PARTLY FROM THE DOWNWASH BUT MOSTLY FROM THE TAIL ROTOR. lAST MONTHS RC HELI MAG SUGGESTED ADJUSTIG YOUR LINKAGE SLIGHTLY ON THE AILERON SERVOS TO COMPENSATE. IE LEFT SERVO OUT ONE TURN AND RIGHT SERVO IN ONE TURN.

NICE SET UP. i HAVE THE SAME EXI FRAME. i AM VERY PLEASED WITH IT. i DONT KNOW ABOUT ALL THE PARTS YET BUT A FEW ARE VERY LOW QUALITY. CHANGE OUT THE MAIN GEAR FOR ALIGN. THE SWASH PLATE IS PRETTY BAD TOO. OTHER THAN THAT IT IS VERY COMPARABLE TO THE TREX SA. WELL MINE IS. i HAVE THE ALUM FRAME WITH SOME PLASTIC ON THE HEAD. i ASSUME THE ALL ALUM HEAD WILL BE A LITTLE BETTER.

GOOD LUCK GETTING OFF THE GROUND. JUST GO FOR IT. ONCE YOU ARE OVER THAT FIRST HILL YOU WILL BE FINE.

I did notice that the gear underneath the main gear tracks a little up and down. Only about a 1/16 of an inch, but after spending all the time to make everything perfect, it looks bad having a part wobbling slightly. It will probably be the first part I replace (other than any parts that are broken in my first crash.. ) My buddy said that his older Align gears (before the blue ones came out) did the same exact thing and not to worry too much about it.

if the main gear is wobbling a little you could be missing a spacer. At least on my hk450 there is a small thin spacer that fits on top of the main gear.

Also when you goto lift off it is normal for the heli to want to tilt slightly to the left and want to move to the left. It does this mostly because of the direction the rotor's are turning and being so close to the ground. Heck even the real things will want to do the same thing.

Hey bro,

With the 401 you do NOT want to use any trim to counter drift! If you do, it will work for that flight...then when you re-initialize the heli, the gyro will consider the newly trimmed position as center and the drift will return.

Re-do your tail setup watching the Finless vid again.

Good luck,
Skarn

I HAVE FOUND THAT THE ALIGN GEARS WOBBLE TOO. I HAVE BEEN TOLD BY EXPERIENCED PILOTS THAT THEY ALL DO THIS TO SOME EXTENT. AND JUST KEEP IN MIND THAT ALIGN QUALITY IS NOT PERFECT. THERE ARE A LOT OF THREADS REGARDING THAT TOPIC. THE ALIGN ONE I JUST PUT ON IS WORSE THAN THE EXI ONE WAS. IT DOESNT SEEM TO AFFECT FLIGHT BUT IT SURE IT UGLY TO WATCH WHEN YOU LAND AND CUT THE THROTTLE.

I do remember reading that and seeing it in one of the videos. I'll check that out tonight when I try and put it in the air. I may have to reset the center position of the gyro. Thanks

Make sure when you set the center of the servo on the tail that you have heading hold mode off. It will be impossible to set the center with HH on as the servo will drift in.

Also watch the finless setup video's and make sure your servos are working in the right direction and working together.

Just went through two battery packs, got it to hover about 2 feet off the ground about 5 times for a minute each time until it started to get away from me and I had to come down. Sounds ridiculous, but I don't think I could do another pack right now (whew), I'm just happy it was in the air and came back down in one piece.

Now that I 'know' it will fly, I'll just have to keep pushing it a little more each time. I want to get the hovers a little more stable before I go trying any tail-in movements.

Here's my other hobby that might get in the way of spending $$ on the heli.. I've been wheeling that Jeep for about 10 years now and I would hate to add up all the repair parts I put in that to keep it going.

It looks pretty in that picture because I had just finished repainting it... Before I redid it, it looked like this:
