That upsidedown thing ?

[duzie]

Hi everyone,

Just to start off...Wow, how cool is this site, Loads of info for a newb like me, but ....i know this may put a smile on some of you well seasoned heli dudes but i've got to ask.

How does that upsidedown flying/hovering thing work ?

Why doesn't the lift created pull the heli to the ground ?

I know , theres something going on here new newbs like me dont get, or is it just me :?

Have been doing my research with regard to purchasing a heli , think my final decision is....Reflex xtr for however long it takes then a Raptor 30v2,
what you guys think ?

As i said before this site is the dogs doo darrs, have looked for, but cannot find a "jargon buster" ....not sure wheather
ive just made that up or not....anyway, you know what i mean, somewhere that gives an explanation of expressions ,me been a complete newb (my new hobby is in its second week) i still dont know what ,nose in, 3d flying, swash plate, i know what that last one is but you get the idea.

Cheers...........all the best

duzie.

hi duzie,
firstly welcome,
the upside down thing is actually called inverted it works basicly like this,the rotor blades tilt up or down in a collective pitch heli this is called pitch the pitch of the blades in conjunction with the throttle make the heli go up or down, in inverted the heli is upside down the blades are at negative pitch therefore the thrust is going the opposite way to normal enablinging the heli to hover or fly,nose in is flying the heli when it is facing you,tail in is when the heli is pointing away from you,3d is areobatic flying,
xtr and raptor 30v2 are a good choice in my opinion for a newbie
hope this helps you with this great hobby

Nice one mackem,

Everything is much clearer now.

I'm well chuffed, just found out theres a dedicated heli club about 3 miles away from me...and they've got tea making facilities...how cool is that
Need to get down there and have some long chats and a nice cuppa tea, get some of that all important knowledge.

Am going to town at the weekend ,a visit to the model shop to buy xtr....feel like i'm boring you guy's with idle chit-chat but i cant wait. I'm like a little kid with a new toy, or in reality a big kid without a new toy :cry: .
Only two days though. and 11 hours and 51 minutes and 26 seconds....25 seconds...24 seconds...23..... . . . :lol:

If you are going to purchase XTR (which is superb by the way) you will need to decide what transmitter you will want to use. Dont scrimp if possible as many functions that are "desirable" are not available on the lower end transmitters.

Look for a minimum of 5 point pitch and throttle curves (e.g. a Futaba FF6 has only 3 point pitch, whereas a FF9 has a 5 point pitch - wish it had a 7 point though!)

You need help :roll:






Welcome to the club

Buying a Tx is a tricky thing because if you are going to stick at it, the learning curve is huge for some, buy the best you can afford. I started with a JR X378 and outgrew that very quickly... Most people tend to go for the cheapest they can get away with and soon find the limitations.

I now use a JR PCM9X which I'm happy with, it has 7 point curves but I find most of the time I don't use them but then I'm mostly electric these days so maybe that is why...

[Butuz]

I have a cheap TX - and i say to you now. Dont bother.

If your serious about Helis and you know your gonna stick with them. Get a Futaba FF7 or FF9 (or the equivalent JR/Hitec/Sanwa) now. Its the only one you will probably ever buy.

Im a futaba man myself. Will be getting a FF9 at some stage in the future.

[duzie]

Thanks for your reply's guys.

Have been looking to get a jr x2610 ,Have seen them recommended in a few forum posts, would anyone advise whether its NOT a good idea to get one for some reason.

One day and 10 hours and 45 seconds...44 sec blah blah blah.

[Butuz]

Hi I cant advise what TX to get because i have had none of them.. What i will say is this. (probably only make sense if your from the UK)

Some people like Fords. Some people like Vauxhalls. To all intents and purposes, they make the same things. But, if you talk to a vauxhall owner, they will say its _thee_ best car far better than a ford. If you talk to a ford owner, they will say its _thee_ most reliable car i ever had, far better than a vauxhall.

Personally i had a ford focus 2.0 ghia for 6 years - it was _THEEEEEEEEE_ fastest and most reiable car i ever had!!!! It did 130 no trouble, and it started on the button every day ****





















**** but the only other car i ever had was a 1981 mini 998cc........which was slow as shit and only started whilst i was under it getting covered in oil.

[Ade_Law]

butuz, to some extent you are right... especially if you look at the futaba/JR 9 channels there is very little in it. One has a nicer feel to the sticks/switchs the other has much more flexible switch assignment.

However..

when looking at the 6/7 channel radios. There is only one.....

Futaba 7c

It has 95% of the features of the 9c but in package half the price. The others simply cant touch it for features. The only one that comes close is the JR 2610 which has a slightly nicer feel to the sticks and casing but looses out from only being 6 channels, only 1 idle up, not enough switchs meaning you are forced to put gyro gain on idle up or loose throttle hold.

dont even get me started on hitec and sanwa!

this is not an opinion but an observation... why spend the same money on something with less features?

ade

[Butuz]

Agreed mate. I only mentioned Hitec/Sanwa because i have never had experience with them so could not write them off.

10 years ago i swore by futaba for my TX and KO.Propo for my servos in my RC Cars, times have changed big style but i will be buying a FF9 as my next TX and where is KO now? I see none in the field of helis dont tell me they gone bust?

Butuz

[Ade_Law]

KO are stull around some people use one of their dual voltage servos on 90 size helis. I had one on my dynax 9kg and 0.06secs AND accuracy too. I went to a couple of local indoor 10th scale touring car tracks and there were a bunch using KO radios there.

Ade

[Smoothound]

I use KO servos in my cars and a lot of the car guys use KO Helios radios, they just don't do our typ of Tx as far as I know and the servos start around 80 for standard servos.

Hi
I'd have to say for 130 pounds the 7 is probably the best
buy for Tranny only.

5 point pitch curves etc mixing and such.

I got the Futaba 7 just about christmas time ready for the Predator
I know have and it just takes a bit of getting used to like all trannys.

It is unlikly you'd need another tranny other than the 7 once you have it
if you got the 6 you'd be after a new tranny after about 6 months or less.

[phil485]

The other point to consider is what other people in your local club/area are using.

If you are goingto join a club or use an instructor and they all use JR, it would be betterto use JR too, just from a ease of learning etc point of view.

For my 2p's worth I love my Futaba FF9

[Dedcalm]

Whatever you get you will always fancy the next one up... I had the FF6 btu ran out of channels so upgraded to a FF9. Very nice radio and does everything I need (at the mo). But it does have its down points, 1 of which is 7 point curves.

I wonder if the newer FF9 Super has 7 points? Also how many points does the WC2 have ? I guess they will be using 7 at least.

Rob

BTW not had a Vauxhall so cant comment, have Mazda and Subaru both of which are excellent... even so there is no point comparing a reliant (FF6) to a rolls (WC2)
