View Full Version : Suzi Hans build
01-29-2010, 10:03 AM
Finally started my Suzi Hans build and am extremely anxious to get it in the air. The 2.6mm thick frames are a nice touch and the heli is extremely light. Hoping to get it in the 9-9.5lb range. Thought I would post some pics on my progress so far and the equiptment I am using.
Suzi Hans conversion
Scorpion 4035-400 motor
CC 85HV esc
CC PRO BEC (still deciding whether to use this OR a seperate reg and 2S lipo)
Futaba 617 receiver
Align 610 servos on the cyclic
Futaba 9256 tail servo
Align 3G FBL system
RJX FBL head (modded swash driver/arms)
Only thing left to get are the batteries. I am looking at the enerland 6S 4270 packs from RREmodels for their lightness and descent cost. Considering the turnigy packs as well, they are pretty hard to beat for the price however the shipping cost of $69 for 4 packs has held me off. Hoping to finish it up this weekend and maiden it next week.

Looks nice, how much frame assembly did you have to do? Where all the holes and what not drilled out for you or was it a straight up kit and you drilled everything? Only reason I ask is because I saw the manual for this and the drilling and assembly looked pretty intense.

basically the way you see the frames in the pics are how it came. The frames now come assembled and there was really no work involved. The only holes that were not drilled were the holes in the motor mounts. I received a carbon fiber mount and the newer aluminum mount. They were not fully drilled however they did have dimples to show you exactly where to drill which took about 2-3 minutes for drilling 3 holes. Other than that all I had to do was put the 2 bearing blocks in, put the skids on, slide the mainshaft/head on, tail boom section and thats about it. Kinda boring actually, I was looking forward to some sort of build :D. I am very Impressed with it!

Starting to look very nice ;)

The anticipation is killin me, just waiting for the rest of my electronics to arrive monday and will be on my way!

I'm flying the Turnigy 6s 5000 (the cheaper/lower C ones, I don't remember the exact number) on a Suzi-Hans frame. They work GREAT and the thing is lovely to fly. Monster power.
I'm flying a Kontronik Jive, so I'm using the built in BEC. This is about the ONLY controller where I'd do that. With the CC Pro BEC, you'll be fine (assuming your soldering skills are OK). I wouldn't add the weight and hassle of a separate RX bat.
You'll really like this heli (assuming the Align fbl is good).

yeah I decided to put the pro bec on to save weight and not have to worry about charging another pack. Looking forward to the 3G.

Been waiting for this... Looks great :thumbup:
01-30-2010, 08:22 PM
Thanks bpd! Gonna try to finish it up this week around my work schedule.

Sweet it is coming together real nice
The frames come pretty much ready to add all your stuff in .

I'm considering this kit as a scratch build, just getting the Trex parts needed (as opposed to a full 700 kit). A couple questions for those in the know...
The Conversion frames come assembled. Do they come with the alum spacer/supports installed, or do i still need to get those separately and cut to fit?
The lack of support at the bottom kinda scares me. Wouldn't a bottom carbon plate cut out as a cross support add substantially to the strength of the frame while adding very little weight? I've heard that the screws tend to pop out and strip the threads in a crash, and I'd imagine that a bottom cross beam support would help alleviate this.
When looking at pics of the swash, the control links at the servo arms are offset from the swash. Seems odd... why? Wouldn't it have been better for the servo geometry to have them (the servos) positioned slightly forward or aft to keep the geometry straight?
I thought I read somewhere that the KDE motor mount and shaft support could be used on this kit, but when searching for the post again, I can't find it. Is this true or am I imagining things. All this talk of stripped gears and broken shafts makes me want to run a motor shaft bearing support.

I am building the suzi hans conversion as a scratch build, I wanted to keep my 700N as is. By aluminum spacers I'm guessing you are referring to the bearing blocks which you will need. Right now I have the carbon fiber motor mount installed, the kit also comes with the aluminum mount that I may try for better heat dissipation. I basically bought the tail section, bearing blocks, and skids.
The kit comes built and there really isnt much to do except install all your electronics. The frames are very thick and I am told from people who have crashed them hard that they held up with no problems. If need be you can order just the replacement frames.
Not sure about the linkages yet as I am just about to install my servoes and everything else today. I can report back on that if it becomes an issue.
As for main gears stripping, I went with the scorpion 4035-400 and will be running either a 19 or 20T pinion...possibly even a 21T. I havnt personally heard of anyone stripping gears with this combo and is one of the reasons why I chose this motor.
I am hoping to get it ready to fly by tomorrow and will post some more pics of the finished heli.

By aluminum spacers I'm guessing you are referring to the bearing blocks which you will need.
I mean the aluminum spacer/supports pictured here...
02-01-2010, 11:48 AM
yeah my mistake I just realized what you were talking about when I looked at my heli. The aluminum spacers are included and installed.
02-12-2010, 07:25 PM
Finished with the build, ready to maiden it tomorrow weather depending. RTF weight is 9.2lbs.

Slick looking heli....
The pictures don't do it justice...What I mean by that, It's hard to get a picture up that really shows the thickness and rigidity of that frame set. First time I saw one on here my first reaction was, " Looks flimsy" Then I got to actually put my hands on one at a fun-fly last October....REALLY REALLY NICE.....
Please give a report after the maiden on how everything works and how you like that 3G.
02-12-2010, 08:44 PM
I definitely agree with you on the pics not doing it justice, it feels VERY strong and I am amazed by how light it is for a 90. Will get it in the air tomorrow hopefully.

NICE JET! Great looking build. Let us know how she does!

Im am considering a Suzi Hans trex 700E build from scratch as a few of you here have done.
I have a question about battery size.
The most common battery size for a 700E is 12s 5000mah
Considering the low weight of the Suzi Hans Build do you think you could get away with
2 x Hyperion VX 6s 3300mah 35C That i am just about to buy for another Heli, they can provide a constant amp draw of 115amps with peaks of 214amps 65C!!
What flight times do you think I could achieve with the 3300's?
I have no 3D intentions I just want to be able to do basic aerobatics.
The Suzi Hans kits look awsome ,it has many features i prefer like direct to swash servo linkages and the slide in slide out battery tray I'm very very tempted!!
Thanks in advance for any feedback

Suzi-Hans, Xera Motor, 2x5000 packs draw current as shown below. Your setup should work. The flight below was about 3 minutes and used about 1400. So, if you use .8 of 3300, or about 2640, you should be about 3300/2640*3 = 3.75. Maybe 4 minutes if you fly more gently or your lighter setup uses less.
Crank up the headspeed, and/or really yank it, and your going to drop below 3 min.
02-14-2010, 01:10 AM
Thanks for the feed back
I thinnk your right the bare minimum you would probably want to use is 4000mah
5000mah is really the corect size for a 700 size heli.
Thanks for the graph.

Very Nice Jet
We have flown 2600 too 6500 Mah packs i The E conversions. Depends on flying style for packs IMO.
I myself prefer the Lighter feel of the 3700 to 4000 mah packs
02-15-2010, 11:25 AM
Right now I am using the 6S Enerland 4270 packs and some turnigy 6S 4000's tryin to keep the weight down.
02-15-2010, 01:16 PM
What are teh average flight times you are getting with those Packs?
What style of flying do you prefere?
02-18-2010, 06:29 PM
FINALLY- got a chance to fly my suzi hans today......all I can say is WOW- what a BEAST! The power to weight is absolutely incredible! It feels so light in the air, especially with the 4000-4270mah packs. By far THE best heli I have ever owned or flown.
