Lepton Pinons are coming!!!

[AdrianM]

I have seen that there is a lack of high quality pinion gears in appropriate sizes for the Hirobo Lepton EX. The stock pinons are not a good match for all power systems and alternatives are impossible to find.

I run a company that imports R/C cars and I have contacts to get high quality hardened steel gears made to the proper specs. These gears will run quiet, true and may out last your heli.

I want to get an idea about the demand for specific sizes so if you could respond to the poll it would be much appreciated.

These will be also be available in the correct sizes and pitch for the Trex 450, 600, Logo 10/14 and Raptor 550E/620E. Check the threads for these helis and vote in the polls for their pinions.

AdrianM,
I would like to see both 20t and 22t pinions for the Lepton. Only allowed to vote once!
Gus...

I voted 21t which with a Hyperion 10 turn and 4S should be a headspeed of 2,750. This is based on Finless' speed of 3,010 with the 23t.

I know that there is more to account for than just gearing, but only looking at changing gears this is what each should be:

21t 2,748

22t 2,879

23t 3,010

[AdrianM]

Thanks for the response guys. I am doing this to get an idea of how may of each pinon to get.

[Voyager]

I would probably buy on of each :)

[CRAZYKEV]

I would probably buy on of each :)

:mrgreen: I would do the same

[3secondsToImpact]

Count me in for a 21t, 22t and a 23t.....Please God, let there be pinions

[clever]

I would definitely buy one of each.

[Finless]

For those wanting 5S you may want a 19T depending on Motor.

[Jafa]

I would go for five 23T and one 22T
(For the Sydney Lepton boys)

[AdrianM]

I have a web site in development now. It will go live in early January. The pinions will be in stock by mid to late Janaury. As soon as I have confirmation that the pinions have been completed and shipped I will let people start placing orders.

[CRAZYKEV]

I'm the only one that thinks a 21t would be nice? No biggie, a 22t would be just fine :mrgreen: I would also buy a 20t.

[Learn to Fly]

NICE!!!!!!!!!!! :WOW

20/21/22 I'm all in. Let us know when they become available, I just want a cooler run and moderately high eadspeed. I gather the stock is too much of a load. Eric

[AdrianM]

Hi Guys...The pinons (all sizes) are all on order and will be here in late Janaury. I am developing a website to sell them. I will post info here and go live with the website as soon as I have confimation that the pinions are done and have shipped.

[CRAZYKEV]

Excellent! What pinion sizes did you end up ordering?

Whatever it is, I'll take one of each and ready to send money whenever you are ready! :mrgreen:

[AdrianM]

Everything size 19 to 23 but going heavy on 20,22 and 23.

[CRAZYKEV]

Are they the same size as the Hirobo ones? I am talking height of tooth and the shoulder. The Tamiya ones are to short on both aspects.

Thanks for getting these made for us Adrian!

[AdrianM]

Yes, the same as Hirobo so the teeth are the same width as the main gear. They will have 4mm set screws so you can get them tight too.

[buster1]

I would take a couple of 23T pinions - please advise when ready,
Thank you,
JH

[andrebandre]

i would like one of each.even though it is labourious to replace them i would like to experiment with each size.

[toyturbo]

the hirobo pinions are actually 2mm taller then the main gear.

[AdrianM]

the hirobo pinions are actually 2mm taller then the main gear.

Then they will be 2mm narrower than the Hirobo pinions ;)

[CRAZYKEV]

It would be better if the pinions where 2mm wider than the main gear. This allows some room for the main gear to move around a bit. Also would be easier to set the pinion height.

Any way to make them 2mm taller?

[AdrianM]

Not at this time and honestly this is not an issue. Finless and Aaron Shell from R/C Heli tested prototype gears that were 2mm narrower than the main gear and had no issues. I had the production gears made to match the main gear width. Any wider is just excess weight and unecessary rotating mass.
