Stiletto First Run w/New Boat

[ron1950]

I'll give it a try as soon as chuck sends it back. Do have one new in package. Should I use it raw or just wait for balanced etc one?

I would never use a raw prop... especially an Octura. Wait for a sharpened/balanced one.

In the meantime, a Grim/ABC 42x55 is also a good prop. You can bend some more pitch into it slowly as you build up to speed...

Knowing nothing about working over a prop I take it a grim needs work also before use

The Grim props can generally be used for general use right out of the box. They still should be sharpened and balanced, but can be run as they come.

Beryllium Copper is nasty stuff...

If you're going to work on props just make absolutely sure you're protected, this means goggles, respirator (not just a simple mask), gloves, long sleeves shirts

And make sure you clean the area and wash your clothes right after you're done.

The guide here on OSE is the best I could find:

I made two runs yesterday with the 42 X 55 prop. I should have given more detail. I have 5.5mm bullets on everything. I ran the boat for 4min each time. 4s 2p 5000mah 40c thunderpower lipo's. Full throttle except I slowed way down in the corners (chicken effect). My heat index for electronics was high, ESC 142 batts 128.My connectors were 172 deg but hold up fine at that temp. I also live in Arizona and it was 106 degrees that day. No temp on motor. I thinking of running without the motor cover for a run and see what the temps are with 42 x 55 prop.

keep us advised on that temp with a 42x55 as i ordered one today lol...

Seems like your running a nice set-up good choice on the batts and run time and good job with the 5.5's. Due to the heat outside maybe cut the runtime down by a minute on such a hot day and disconnect the bec and run a rx pack my help. Are you running 1 lipo or 2 paralell?

[ALD]

I'm running 2s 2pack in series. Stacked toward the front.

If your going to run 42 x 55. I would advise cutting holes in engine cover and 5.5 connectors everywhere. When you use your throttle start real slow.
The boat is a rocket. I cut the steering travel to 90% and used 20% expo. Have not tried turning at high speed yet. I also tested boat with stock sharpend/balance prop and ran much better and little quicker. Easy to learn on. The big prop is scary fast but down the straights tracks true.

I've taken your suggestions and added them. Thanks. Here is how it reads now.

Warning- Potential Cancer hazard!
Take caution when working with Beryllium Cooper! Activities such as grinding, sanding, polishing or any activity which abrades the surface will cause airborne dust particles. These Beryllium Cooper particles are highly toxic! There are dangers involved with inhaling dust or fumes. It can cause serious, chronic lung disease in some individuals. Over time lung disease can be fatal!

If you're going to work on these propellers make absolutely sure you're protected, this means proper eyewear, a high quality respirator (not just a simple cloth mask), gloves, long sleeves shirts. Immediately after your work is completed, proper cleaning of the your work area is also suggested.

I have to get my props back from Egneg. I don't want him to DIE!

[ron1950]

Well, he prepared 2 props for me too, I didn't ask, but I assumed (and surely I hope) he uses proper protection when working on them.

I would feel horrible if anything were to happen to anyone just for my hobby!
