convert 600npro to belt drive?

[moyesboy]

Can anyone point me to a parts list of what I need to convert a 600npro to belt drive?

Are the belt drive bits just he ones from the 600e? becvause none of the shops seem to list the belt drive shaft in "600n spares".

does the belt drive tail shaft just fit into the pro ali tail box or does it need oter bits, or a plastic tail case (or dedicated belt ali version?).

Thanks

I know there's a post on HeliFreak that spells it out. Can't get HF working at the mo tho.

Try searching it from your end?

Did this on mine...all you need is this...

H60078 : ALLY' TAIL DRIVE GEAR ASSY' - TREX 600
H60132 : 600 Metal Tail Belt Unit Set
H60036 : Tail Drive Belt

Mo got my NSP converted to belt drive very simple job tbh, maybe not the cheapest as the you need the whole new tail box belt version assembly but in my view worth it.

[Mart61]

Still can't get Helifreak up. However, when I priced up all the bits needed to do the change, I'm sure it only worked out to cost about £25 or less. Might be wrong tho...

I'll keep trying HF.

It says:

"Q: I have a Pro (or Super Pro) and crash a lot, so I'd like to convert the tail to belt drive to save money on crashes until I get less crash prone. What parts do I need?

A:
H60079 Metal Tail Rotor Shaft Assembly = £5.81
H60078 Metal Tail Drive Gear Assembly = £7.75
H60043 Tail Case = £7.28
H60036 Tail Drive Belt = £5.81
Two M3x26 or longer cap head screws (included in H60047 fin set or third party M3x30) = In your spares box or local hardware store? Copper's I'd have thought?
Two M3 locking nuts (also included in H60047 fin set or third party)" = In your spares box or local hardware store? Copper's I'd have thought?

I didn't opt for the cheaper tail case for me I wanted the NSP look therefore it costs a bit more...

[moyesboy]

What a pity its not possible to put the belt shaft in the gear drive tail. So I get a plastic tail case.
I was wondering if it could be done for a similar price to a 3 set of front tail gears...
However it looks like it has to wait until I broke my last torque tube!

I'm not that worried about the looks only about how it flies. I am running a 600sport and a 600pro and I can't tell any worthwhile difference between the belt and plastic tail case and the torque tube drive.

What is the benefit of the conversion?

[Si Goodchild]

Reduced susceptabilty to damage on landing?

[Stuart]

If the tail blades happens to touch the ground on an auto or just say uneven ground then this will cause the tail gears to come under stress and usually either on he first instance or over a few times of doing this you weaken the gearing mainly at some point between the tail gears to the bevel gear that feeds the tube drive. They are designed to fail - you'd rather replace a small gear and next to nothing cost versus a main gear. If however like me I have a poor habit of hitting the tail on auto's (must get into the habit of turning it tail in and tipping forward). The belt drive will give a little even to the point where it might jump the teeth but by doing so the tail belt is weakened but is unlikely to completely fail so you get a bit more life from it - plus in repair costs a belt is about half the price of the tube drive.

Thanks Stuart. I was thinking that maybe the belt could maybe change the flying characteristics.

Thanks Stuart. I was thinking that maybe the belt could maybe change the flying characteristics.

The only disadvantages are a slightly less efficent tail system and the possibility of static problems.

the belt is sipposed to have more drag than the gears. This doesn't seem to be very noticeable. however compared to other belt drive helis the 600n should be a little worse becuase it still has the satep down gearing before the belt starts, rather than the belt going round the bigger gear using ideler pulleys like the raptor/beam/kinight3D.
If you are getting short on head speed at the end of the auto the belt is more robust compared to the tail gears stripping - due to it having a little bit of elasticity.
My 600n sport (belt) runs a 720 and 9254 and my pro (torque tube) uses a 720 bls251 and there isn't much difference in tail performance between the two at all.

With my raptor and knight I didn't damamge the belt in the crashes they had and the belt in my 450 just goes on and on and on.

Regarding crash cost three sets of tail gears are £16. I was wondering if I could convert to the belt or that cost - but the tail case is extra.

The torque tube is about £10 for a pack of 1 and goes when the boom goes. It annoys me that they are single when the booms are in pairs! ITs usually only the front gears that go but the back ones still go sometimes. I need front and back gears and this rebuild wil clean me out of torque tubes booms and gears...

Also don't forget that a belt will stretch a lot faster than TT gears will wear.

I knocked the teeth off my tail umbrella gear on my first dodgy landing. Having then fitted the 700 vertical fin to the heli, I've not lost any more.

This could result from the fin or better landings. Probably both.
