Miss Vegas Duece - .150 Shaft Problems

Recommended Posts

My daughter and brothers Vegas keep breaking shafts. Sometimes they break at the stub and some knot up before going into engine collet. We have probably broke 4-5 shafts and several props. Is there any better shafts or recommended modifications to keep the shafts and props intact? It's tough to explain to your daughter that she ran great at race up to the point of the shaft failure. I'm changing the poor quality engine collet they come with. I've replaced 2-3 just because they won't let go of the shaft after just tightening it once. thx in advance

One of the things that can cause the shafts to break is the alignment, or lack there of, to the flex shaft and flex hex coupler. I've had to realign the engine with small shims to allow the flex shaft to slide into the coupler without any bind.

Thanks guys.....I'll double check alignment and look at the octura shaft. It's probably the best boat for the money. My daughter can run it in the RTR and also be very competitive in sport 20 to allow her more race time (since the drivers tend to still run full throttle..... Which cause them to lean or flip engender when they have the race locked up). I can handle the driver errors from her, just need the boat to stay together.

I have a vegas myself.

Octura collet. Yes.

No more than a 1/4" between collet and stuffing tube, tight as possible but enough to release cable. The only time I had curl is to much gap.

and get an octura collet, I see Mike (Toyotatruckin) has a shaft for sale, might work?

That shaft I have comes with a 3/16 stub so it wont work with the 1/8 bore props

You still have that lathe, Mike? It wouldn't take a skilled machinist much to turn one down ;)

Nope, I sold all my shaft and bushing building goodies and all my materials- I built a ton of shafts over the years and things do keep popping up when I move things around lol (except a shaft soldering jig, its somewhere in the garage)

Make sure alignment is on the money,also Teflon liner can cause problems,also prop must be balanced perfectly,found that was the most critical part and the cheap collet must go because damage happens to cable pulling it out when its stuck,the collet for the super v works good or a octura replacement!

Take out the teflon liner and replace it with a peice of brass tube for the .150" shaft and use oil or lithium grease to lube the cable along with the Octura shaft, cable collet and a good balanced prop. This will help and remember to lube the cable and clean and lube after the day's running! You have to maintain your equipment.
