GWS orange Props

[nolasco]

I have discovered that the GWS props can survive crashes if some form of prop-saver were used. Since I normally make my own gear drives, I ream the GWS props to friction fit them on the hub of the spur gear. When a crash occurs, the prop merely pops off.

Unfortunately, this method only seems to work when the crash angle is far from perpendicular to the surface of impact. The prop still survives. But, it's now the spur gear that splits. I have run out of 48-teeth gears in the process.

And as for the small 3x2 props used for direct drive, they seem to be a different animal altogether. I have lost half my supply and they all had the hub split in two.

So, I just buy a nice supply of the props. They sure are much cheaper than the ARC and WesTech props I have but am afraid to use for fear of breaking them.

There seems to be hardly any material there and one rough landing where the blades contact the ground momentarily can easily shear the blades cleanly off.

Again, I applaud GWS, I'm just trying to give a little feedback...

I'm using a GWS EP-1047 on my I.F.O. and have yet to brake 1, and believe me it is not like I do not crash... I do a great 1 point landing. I do have to say the I.F.O. has the carbon fiber wrap around the front. That may be what is saving me.

Thank you for all the good supplies Mr. Lin.

Very interesting. What motor/gear drive are you using on your IFO? Is it rigidly attached to the IFO, or does it break away after a 1 point landing?

I have a scratch built mini-IFO/Mouse hybrid that has sustained several of those crashes while trying out several motor and gear ratio combinations. That carbon fiber wrap around the front does not seem to have done me any good ever since I have rigidly attached the motor/gear box on the frame and employed the prop-saving method I mentioned above. I have since then lost several 48-teeth spur gears, but no GWS props.

Any ideas why I am killing spur gears but not props?

I'd like to thank Mr. Lin for supplying us with those perfect, lightweight, economical props. I just "balanced" a shipment of 9.

I use a magnetic balancer which has feather accuracy. I don't bother with hub balance. All were "right on" except 2, they required a couple of dabs of clear nail polish. The hub imbalance was so little that they'd swing for a minute or two in the horizontal position if I waited that long.

Also, thanks for the Tiger Moth. I'm building one now. I think it's an excellent design.

The motor and gear is the same as the one ont the light stick. 5 to 1 I belive. I'm runing an 8 cell Nickel Cadmium pac. The fun only last 4 to 5 minutes. The motor is held on by zip ties. You can see my motor mount in the tips and tricks of http://www.flyifo.com or http://www.angelfire.com/electronic/MyHobbyShack/

I use a dual B2 motor gear drive with an 8:1 ratio. Initially, it was just glued to the carbon "fuse". But I soon got tired of that setup when a crash always resulted in the drive and/or one or both motors being detached. Sometimes, one or two wires were also cut.

So, I decided to rigidly attach the gearbox to the fuse using dental floss reinforced by CA. That solved the detached gearbox/motor problem. Unfortunately, the spur gear now became the weakest link. It split into pieces during 1 point landings. I lost three gears in a row that way. :(

GWS thanks for your suggestion.

Origial ideal to it eazy broken is, my hand had been cut by other propellers so many places. Forgot to show you during my speech at SWAC!:D

And many years ago, Taiwanese RC flyer who hit a lady and paid a crazy high amount of medical compensation ( we don't have so many insureance coverage to paid for that.)

If you feel rather get prop stronger is better, I can ask my R & D to trim the tooling make the root jointion stronger.:p

Sorry, cause your inconvenience!

w rgds, wish you fly better!
