Good link to a nitro starter

Nice video but it is no where near the baseline of Ben Dover Productions Ltd !

Seriously though, Your vid has convinced me - i think ! - dynatron seems to be highly regarded and I have yet to discover anyone on the web who has a negative view on these starters. I personally tend to believe that people do not tend to spend hours on the net telling the world how good something is. I feel its human nature to complain when things go wrong, seek advice, and get help/views. So perhaps a reasonable approach is to look at negative comments on the net about Dynatrons - which I havent been able to find as yet. Just my way, but others will doubtless have something that works for them.

I don't use one, I bought a cheap JP starter years ago, lashed a 5S LiPo to it and haven't had issue. More than enough to start a 90 never mind a 50. I haven't had to replace it but if I did I would buy a Dynatron. Some buy once and buy right at whatever cost, some buy what they can afford at the time to do the job, I'm the latter.

I spent more on the wand than the starter

[helijohn]

I couldn't resist, sorry

a

I'm glad you couldn't. I guess it means more to those that have suffered with naff starters.

I've had a few of the Sullivan types and I currently use an old Taiwan made starter but when it comes to the big stuff like 90's IMHO it needs a good powerful one.

I recently bought an align starter, which has performed really well on my os50 using the the align 2in1 for the glow. whenever I start it, Panos stands behind me with his dynatron, like a vulture waiting for its prey to die, but it has always been fine. Then, I removed the 2in1 (after many recomendations) and put on one of those little blue pushglo devices. Now, on the first start of the day, the starter vibrates like it does in the video and takes a lot longer to start.....! its perfect on subsequent starts. In came the dynatron at this point and the extra power has it started in a flash. I have to put it down to the push glo device.

Hi buddy, cheers,
Can you apprise as to what the performance and reliability has been with this so far as in your experience of using it.
Thanks again,

I have had the unit 7 years and it's not let me down yet.
The barrel is not to cumbersome so you can get a good grip on it.
The heli starter shaft that came with it just pushes in to the starter cup , but I found this arrangement a bit unnerving when it was in use, so I bought an upgrade shaft and quick release connector, much safer to use.
The unit has never showed any signs of being underpowered when starting my TT39pro engine.
So it does the job very nicely, one thing I am looking into is some sort of cradle that will fix to the barrel and allow me attach a couple of lipos or nimh's just so I can increase the portability of my setup.
The yuasa battery I mentioned in the op are very good replacements for the household alarm which is where mine ended up at the weekend.lol the one I took out had ripmax on it so that explains where my starter batteries keep dissapearing.

What with the scientific proof Mattie and Richie gave - indeed showed above, plus all the good posts I think you have your answer but for one last go at convincing you picture this, its a perfect winter day, crisp air, bright sunny blue sky day with barely a hint of wind, you ruck up to your field and can't get your heli started. This WONT happen with a Dynatron but may with other starters. How much is a days flying worth to you?

Been there, done that and got the T shirt. I sold all my equipment about 6 years ago but kept a few spares and such; one item was an old starter. I know it'll crack a 30 but I know it won't a 90.
Do you have a link to Dynatron please or is the same as this?

A friend was starting his heli one time and the wand span out and cracked his radio's display. Incidentally it is one of the reasons I use a freewheeling (one way) starter wand.

What is the upgrade shaft like? Would it fit other starters?

I bought the Dynatron ( love the name by the way, every time I use it feels like it will transform to something! lol ) and it's just very smooth to operate, and it has bags of power. The only down side for me is that is just big!
So I bought a second hand Align super duper starter and had a go with it last weekend. Unfortunately I found out that is faulty ( That will be on another thread soon if the seller don't respond soon ) but the video is spot on, the Align vibrates allot and just feels like has no power. Shame really as the size of it it's perfect.

So Dynatron for me all the way.

One thing nobody has mentioned about the align starter is that if you have small hands or poor grip they can easily spin out of your hand easily if your not ready for it

I'll admit that that is very true Just like my VXR torque steer, just learn to live with it

[Boggy]

I've just edited my post Harry I seemed to have over used the word easily with ease far too easily!

[Planehazza]

Easy does it

[Keratos]

What is a 'freewheel' starter / shaft and why would one find it advantageous?

[Delarado]

Its probably one with a one way bearing in it, so the shaft will only provide torque in one direction.

Certain engines dont have a one way bearing in them, so once you spin the starter shaft coupling and the engine starts, the starter coupling on the heli side continues to spin.

If you dont have a one way bearing on the starter shaft then your in a world of trouble as the engine continues to spin when you stop the starter. Most modern helis/engines have a one way bearing in the starter mechanism though.

I think.

[Keratos]

Cheers for that, I comprehend - slightly - and my nitro does have a one way bearing although I had no idea what it is.

What i dont fully understand though is why a one way bearing would stop the motor spinning , because both starter and motor would spin the same direction (no?) so why would the motor stop spinning when you stop the starter, and if it stopped spinning, then it (the engine) is no longer running which was the whole purpose of the starting - I'm obviously not getting this am I?
