TZ 30 & TZ 50 HELI

[sparky]

i had a TZ30 heli kit a few months back which i sold without ever starting it up or ever using it but now im thinking of getting another from revolution models as they are selling both the 30 and 50 sizes.

but i have read lots of bad things about these models yet ade you have the 50 flying on the video and it cant be that bad a model to be flown the way you are flying it!

so how are these models really?

cheers

its worth finding out which line of supply revolution's ones come out and finding the exact spec of them. there are a number of different versions and specs around. The one I had was the deluxe version with the metal head and grips which it appears revolution arent stocking.

If you take the TZ line for what it is which is a damn cheap heli then you will not be dissappointed. Compared to helis of similar amounts of money you cant beat the 30 or 50.

only problems I had were with the auto bearing which only has 1 bushing rather than 2 of the raptor. I also wore the damping out fairly quickly.

As you probably know I have moved onto a knight 50 now, which more expensive but offers much higher quality and precision in both look and flying.

It depends what you are after I think. If you want something that is cheap to fly and will do aerobatics/3d out of the box then a 50 would probably do the job nicely.

If you want something that looks nice and flies accurately then I would go for the Knight.

i was after a low cost 50 as funds are tight. only i didnt want the low cost perfromance even though i know you get what you pay for.

im learning on my shuttle zxx which i bought a few years back and thats been the only heli i have flown. i did have the tz30 30 but never never used it. as such i dont have any experience with other helis. any other ones and the tz30 always look beefier than my skinny little zxx.

i have the full metel tail assy and flybar arm from quick uk on the shuttle. is this heli going to be able to progress with me into mild 3d etc if i ever get to that stage? as like you will see in my other post i think i need a new gyro so funds are tight to be buying a second machine just yet.

cheers

i have never had the chance to fly a shuttle with a decent gyro in it setup properly so I dont really know how well they would actually 3d.

I am pretty sure they cant get the full -9 to +9 pitch range and they have a lot of flybar input making them very stable so I dont think it will get you into 3d.

the TZ is cheap and it does show in some of the parts like I said but it does do the stuff nicely.

I think i would save up for a knight personally.

Mark,

I had a ZXX many years ago and still in fact own my original ZX from circa 1990.. they will 3D to an extent but you have to appreciate the age of the design..

The main shaft is quite soft and the spindle only 5mm.. so make sure you get a decent set of blades.. Anything with too reward C.G. will go out of track easily and bend the spindle. A good set of SAB's should see you straight.

Get the hard dampers for the head from hirobo.. or failing that get the K&S ones for the Ergo (K&S502 3.45).. same dimensions.

You will also need some much lighter paddles.. I used the JR/K&S paddles (JRH96056 3.45) on mine to reasonable effect.

The shuttle is quite light in this day and age for a 30 and has a generous blade size.. this makes it quite a lightly loaded model and therefore quite graceful.. however it doesn't have the control power of some of the newer designs. It will do flips, pirouetting manouvres and even aerobatic autos.. however the weak spots (mainly shafts!) mean that it will struggle with hard pitch pumping manouvres without bending something.

You can just about get +/-10 on the model.. however it does take a lot of fine tweaking to get there..

There is now a 6mm spindle conversion kit for the JR 30/50 models and I'm pretty sure the head dimensions are the same between those and the shuttle.. so you might want to investigate that too.. (K&S1398 19.95) And I'm pretty sure Hirobo do a hardened main shaft for it..

I also have vague memories of having to bend the links slightly that go from the swash plate to the blade mixer arm so they didn't touch the head with extremes of cyclic.. but I'm a bit hazy on the details without having a model sat infront of me!

Hope this info was of some use!

Cheers

that was some really good info on the shuttle zxx.

at the moment i am still a real beginner. i have not flew for about a year now. when i did i taught myself to hover after rob mott trimmed my heli out.

but i do really like the shuttle. i can pretty much strip it and rebuild it now in a few hours( good for when i crash it)! lol

thanks for the help
