I just loved this heli so much but I do not have the peace of mind flying it with the original crown gear. Too bad I can only do this on the Faifa because the main gear is wide enough. I can release the CAD drawing so that other srimokers can get this made by their local machine shop.

Yes please Romeo If you could send over those CAD drawings that would be great

Crown and Bevel Gear
Quote:
I haven't flown it yet but I've used a lot of MA helis with crown gears and there design is pretty bullet proof but its very differant to Kasamas design.

Me either.
I believe all helis have their own limitation and I have reached the tail limit on this heli. Just like the TDR, they have reached the RPM limit so they are building a bigger drivetrain TDR/TDS. |

I flew the same manoeuvres two days before, without reducing the tail pitch and stripped the teeth in three different spots on the crown. I'm also only running 95mm tails, though the head speed is 2200rpm. With the amount of tail pitch at full travel, the tail blades are stalling the drive train.

So exactly how much is the travel being reduced by? I plan to run to a headspeed of 1900 and lower on 105 tails.

Wadders did approximately half, about 20° each way.

It's not a mod, it is a setting in your FBL unit or gyro, just reduce tail throw limits

Fantastic mod by the way... it would still be good to have the option from Kasama to have helical tail crown and gear, but at least reducing the tail pitch gives a solution for people who want to use stock parts.

I would like to get the helical stuff on mine to, but atm i not having problems with the stock parts, mine used to eat the bevelgears in 5-6 flights , even if i had the mesh tight or loose, my pinion had pretty sharp edges.
So, i pulled it out and went over each tooth with a small file to dull the edges some, put it back in with a new bevelgear and set the mesh pretty tight. Havent seen a speck of white dust from the bevelgear after that.

This heli is worry free now to my skill level. Had more than 30 flight on it now without any lubricat on the bevel gears.
I have 1 extra of this mod. PM me if you need it. This will include the modded gear and the machined adapter, no screws included. You will have to buy the other matching bevel gear. |

Is there any chance one of you fine people could measure the distance you're getting between the tail gearbox now you've reduced the throw/pitch? I think I've reduced the throw by around 4/5mm, that sound about right? I'd certainly buy any upgrade that became available. |

I've reduced mine to 20 and 25 degrees. I say there smacking the tail left and right for a whole flight to test it. I find it hard to believe anyone could strip a crown at these amounts. Tail held perfect too.
