Good cheaper than the full assembly solution for the belt drive version to the CF tail case problem.

[littleman]

I'll be honest, I havent had the best luck in the past with micro-heli, its also really expensive IMO

This will be my next upgrade

I've got two of the $60 full tail assemblys. Pricey but I like them. I haven't had to replace one yet. I'll agree MH's support if you can call it that sucks but, so far I haven't had any problems with the Alum tail. That link is the same price as the CF tail from Gaui. Lots of guys on here have had the bearing hole reamed out from vibration.

[Jetleaf]

Buzz did you also notice they have the aluminum bell crank for the tail?

It looks much more sturdy and solid than the one I got from Microheli.

This one is for the EP100. Will it fit the Gaui 200?

Ya seen that.

this looks like a likely candidate for my next tail. i liked the MH tail i had before. i never used the stock one. it took some abuse. then, it broke, and i pieced together a tail with the sock case and side plates. no problems so far. bearings look good in the side plates. i also used the aluminum bell crank.

[SurfCity]

Buzz, how does the full MH tail compare to the stock tail in: 1) performance, and 2) durability? Also, how does the weight compare? The MH tail weighs 10.4 grams.

[Buzzkill]

Performance is on par or beter than the the stock tail with a few exceptions. The biggest one being the slider linkage is attached by screws so it doesn't pop off like the stock slider linkage. Another is the bell crank is aluminum so it doesn't flex like the stock and the linkage seems to stay on better. Lastly it seems more precise, like there's no slop. Rudder inputs are quick and don't feel spongy.

As far as the weight, I did a post a few months back and I believe it weighed about a gram more than stock. I'll have to look it up to see as I can't remember but I do remember it was enough to be a concern for me.

I had two crashes yesterday before geting a single pack through two of my Gaui 200s due to the plastic crap on the tail. One was a stock belt assembly. Don't ask me why I had it on there. Stupidity I guess. The other was the SD TT config all stock. They'll both be replaced with the MH stuff today. The stock will get a full replacement MH tail and the TT will get all the MH gear I can get to fit. It looks to me like the TT tail is a stock belt tail with spacers. If so I'll use the spacers to fit the alum. stuff and post pics if it works.

I had 16 packs fully charged and about 6 people watching me in the local park as both of the helis pyro'd to their deaths after about 1-2 minutes flight. The TT slammed so hard it broke the CF gear. Only the second time I've broken CF LG after many many crashes. I will not be putting stock tail gear on any of my helis again unless I absolutely have to.

While I'm on my soap box, Gaui really needs to address the see-saws and what is in my opinion a equal if not more important problem, the tail. I don't have tail holding problems. The majority of tail holding problems is either a low head speed issue or a setup/gear problem. However, the plastic crap on the tail has got to go. The first several flights on a stock config seem ok but it doesn't take long for the plastic to fatigue, get sloppy, fail or all three.

For a heli this size that cost as much as their largest heli (gaui 550, yes you can buy the 550 for the same price or less) I don't think it would be unreasonable to expect better parts. I was so frustrated yesterday I came about a hair away from dumping my Gaui's. Blasphemy I know and I'm over it this morning but the tail failure rate is getting ridiculous.

[psindrup]

Buzz - I feel your frustrations, reading your post. :bawl

I agree, the tail "arrangement" is not up to par.
It should be better with a heli with this price tag. It is as expensive - or more expensive - than its much bigger brothers. I just bought a T-rex 450S for half the price.

Hey Buzz, I'm guessing you have the SD version - so do I.

I'm looking at the engagement on my tail gear and it looks to me like we need more pinion engagement. The tail shaft gear seems placed right but the shaft gear is too far out.

I pulled the shaft out of mine and added two shims between the gear and bearing ~.0065" this brought a much deeper engagement w/o binding.

You may want to look at yours too.

[Buzzkill]

I'll have a go at it. Not a bad idea. I plan on trying to use the MH parts today too if I ever get time.

[SurfCity]

The tail is under massive stress. At 4,000 rpm head speed, the tail's turning one million revs per flight hour. That's a lot of gear-tooth engagements. Not surprised by the wear.

[eyeflyhelis]

mh issues they use soft metal. the 2 tails on my 450s were awesome by far way better than the se stock tail but they both bent in crashes. a friend had the mh arms and head units and bent all of them also in not so hard crashes.

[Jetleaf]

Something to consider with increased engagement of the gears is also increased likelihood of gears stripping if the tail contacts the ground or anything else. That's why I tend to run mine on the loose side versus tight. Also you don't have to shim to get more gear engagement just slide the tailbox further up on the boom.

Paul, don't even think like that - we need the prime Helista in the mix here. The Gaui board of directors should be giving you parts.

While I'm on a thread -- I have a WARNING: My DX6 lost it's mind while I was flying the Gaui. All my settings for the Gaui and B400 left the radio for a better place. Of course the Gaui literally attacked me and hit the wall behind me and then tried to hit me again. It was horrific and amazing. I had to get it down like a wounded animal and unplug it.
I have no idea why the Tx went nuts. I had to start from ground zero and re-bind on up. Of course none I my setting were written down. You know how you tweek here and there -- all gone - two birds, too. It has been a virtual nightmare. Bottom line - write your setting down. (Maybe I'm the only one that never did...)

[Jetleaf]

I never write them down either. I do create duplicate models in the transmitter but that wouldn't really have helped in this situation. Would be nice if you could back them up on the pc or at least a memory card. Hey I smell a mod.

[Buzzkill]

I'll always love my Gaui 200s. I may talk trash and abuse them but I treat my girlfriend that way and she still loves me. I don't see why my 200s wouldn't too :thumbup:

[psindrup]

Guys

With regard to backing up your nutty transmitter, I have an idea.

Get your pocket (P&S) camera out, put it on a tripod if you have one, and shoot a pic of the vital screens on your transmitter. Not a backup, but a hard copy.

With regard to all the tail issues:

Have you guys considered going back to the belt and use the tail shown in the first post in this thread. It looks really solid and sturdy, and I like the idea that it does not have two "loose" side plates, but it is one solid unit.
I just ordered one to try ...

Peter

[Buzzkill]

I'm going back to the belt. I like the TT better but with my lack of flying skills it just doesn't hold up. Even the slightest scrape seems to strip gears. One more set of gears and that's it for my TT Gaui.

[Gr4yb3ard]

Buzz,

This has gotten to the point of low comedy, lower even, than we usually share up here.

I don't have the tt yet, but I've been thinking there's got to be a set plastic bevel gears out there that will fit close enough to use.

Have you ever opened up a VHS player or kid's toy? Jeez, they must mold a gazillion of these things a day....
....all we gotta do is get a bit lucky on the dimensions and find the supplier.

I say post the shaft sizes, maybe a pic of the gears close up, and get the whole group to keep their eyes open for a beefier set, maybe something will turn up.

Problem is, one is molded on the cf shaft.

Dumb, Just plain dumb....
