hi all.
the new tail gearbox will it be an upgrade or will
it be included into the kit?
lets assume buying a fury extreme , how can one tell if
its coming with the new or old tail gearbox, are
there serial numbers on the kits?
thanks.

Well to be honest... Dr. Ben .I think the tail box should have some sought of cover anyway to keep the dirt out like the competition has... I just don't think you get a quiet true gear out of a mold. If you did, I think we would still be using Molded Main gears...I guess it boils down to quality... A Chevy or a Lexus

didn't think $20 was too bad, either. But then go search for how many times guys complain about the price of the main gear or inner ring gear. If you blow both tail gears, that's $40. I think the major concern was for silly causes for damage, like kicking up a little rock and ruining the set of gears and thus trying to make them somewhat affordable to replace.

lol..... if you're are really griping 'bout a gear that cost $20.00 on a heli that is $1000.00 with all your radio gear which is $2000.00... and then you take into consideration that a tail gear is a pretty important item........ well sorry, but you must be daft. that is just silly... so let me guess, the main shaft and spindle should be made of foil to save weight and cost right! make the gears of paper machea' (sp?) and the blades should be made of bloody silly puddy
you know what... bearings get expensive, so you should take them all out and use bushings! then again, bushings will wear out too... so you should have no bearings, no bushings... you just have to take the entire heli apart after every flight to oil everything! oh wait, oil cost money! god no! what shall we do.... you could use magnetic forces to suspend every part so nothing touches thus, no wear... oh fook, magnets cost money, and that would be technology... yep, cost money!

i know... you could sit on your arse at home, and twiddle you thumb all day.... cost no money........

come on now..................

Some of the main gears they sold were molded then the teeth machined to make them true,they were still expensive. The gear box they have now is perfectly reliable if built right. Most people are just going for the new look.

how can one tell if your getting the new tailbox or not in the Extreme.
The easiest way would be for you to check with your hobby dealer and ask if he has the new kits with the open tailgearbox..I don't there will be a special serial number or anything...or better yet write to Miniature Aircraft

I'll tell y'all an interesting story in the developement of those gears. Granted the cut gears are the truest running. No argument. We've beaten the cost versus quality issue enough, and I was on the side of quality anyway. Anyhow.............some of the earlier samples of the molded gears some eccentricity. For testing, they tested those gears anyway. They flew as smoothly and sounded just as good as the cut gears. The gear mesh on the tail with these gears just isn't that critical. Even if the molded tail gears don't run dead truly, it doesn't seem to have a functional impact on the transmission. This finding lies in contrast to the issues that were found with the main and ring gears. Those parts certainly are at their best when running as truly as possible, and molding just won't do it. If either has a large wobble and high side, the low side gets so loose as to be problematic under load. Extreme 3D pilots can vouch for what happens if you set the from tail tranny too loose. All of you ME's out there can explain the relative issues of gear and tooth coverage in the gears in the tail versus those up front. My lay engineering mind tells me it has a lot to do with those big, fat, deep teeth in the tail gears versus the smaller and finer mesh up front. The lastest test batch of gears have survived all the hell that Henry Caldwell and Eric Larson could throw at them. Availability won't be long now.

imo, i have not had any issues with older cloesed gear system and i do not plan upgrading my tail at all, i beat the crap out of the tail and have not had any problems with the metal gears and thats with a couple of crashes on them.

Dr. Ben


Dr. Ben
Dear Dr. Ben: Not sure if you are a democrat or republican WHAT A SPIN....For your info when you have a tail boom sticking out 25-35 inches and the gear mesh isn't as smooth as possible not even mentioning hte noise factor from molded gears ( do to the lack of a good gear mesh from molded gears), the ensuing vibration will be transmitted thru the drive train maybe even more then if the Main Gear wasn't meshed right. So, I'm not sure what u mean when you say not criticle.. I'm sure we have all had tail gear mesh problem with metal gears that weren't set correctly.. and that vibration was awfuI for one will opt for CNC gears if someone makes them ( I hope !!!!!!!!)

Hmmmmm
Even if my metal gears were not meshed correctly, I never got a vibration. Noise, yes, vibration, no. The metal ones whined something awful until I got the mesh correct but, if they were not damaged, they never vibrated, at least enough for me to tell it and I'm pretty picky. (Not as picky as Dr. Ben. )
If the molded gears are true as far as diameter but have front to back play (as can happen when cooling a cast gear) they still seem to work as well as the ones that are machined. I was as surprised as anyone when we found that out as I was not expecting it. In the front pinion/main gear mesh, if the main gear had up and down play, the TR pinion tended to peel off teeth on the crown gear, hence the very nice machined main gears and crown gears that reduced that play to acceptable levels.

blakka... you really feel like you need the -new- style?

they are the same gears that are in the hirobo box... (not the metal box of course)

it's fine... just keep it lubed, and set you mesh correctly....

when you kill it by slamming it into the ground get a new one

besides, last reports i heard were not that imressive...

When you say "They are the same style" do you mean the new ones or the current metal ones? I am not being a smarty, I actually am currious. As I have never built a Hirobo machine. I personally have no issues with the current tail box design of MA helis. So I see no need to absolutly have to have the new tail box. But that is me.

Build it, fly it, crash it. Repeat as often as needed.

both actually... lol

the only difference in the metal gears is that the Hirobo ones are helical cut, and they are harder... believe me, those gears aren't going anywhere... i've tried to kill them they will eventually wear like the MA ones, but it's very unlikely they will fail you... unless you've completely fooked something up in the build... even that is hard to do though..

the biggest difference in the plastic gears..... Hirobo's are white, and MA's are black (last i say anyways). the Hirobo's are machined derlin as well.. blah blah blah....

go have a look at the Hirobo tail box (plastic gear one)... ie standard TT conversion for a freya... you will see very much that same thing as you will see in the new MA box.

Well Im getting one, I have not had problem's with my old tail box's, But I think it's worth a try. Cant judge something until you try it.

MOLDED VERSES MACHINED TAIL
Aside from what Dr.Ben and Gordie and other PR MAS guys are saying about molded gears being as good as CNC cut gears.There must be a reason that Hirobo and JR use machined gears not molded ones wonder what that reason could be?????? I guess they just like charging their customers for a more expensive un-needed part. If the Hirobo machined gears are the same design as Miniature's "molded " gears does anyone know the part number as I guess this is the best way to go...Maybe in time even MAS will see the light
