Got home last night and all unpacked. Defeated in my effort to match the European 1-Cell Hydro record of 88mph, but successful in finding about 50 ways NOT to go that fast. ;-)

It was another fun trip, highlighted by Brian's epic P-Hydro runs, any Tony's great stories!

I'll add some pictures and videos tomorrow once I get them downloaded.

A very crooked M2-Hydro set of passes.... Note to self... bump the steering trim LEFT, not RIGHT!

A Tour of the Pits (Forgive the quality... this was taken from a Facebook "Live" post, so the quality isn't that great):

I'm going to do something I rarely do: Here's the entire setup.
Hull- Raptor tub, SAW front sponsons, no rears.
Motor- TP3650 2Y 3080kV Thanks Jun Lin!
ESC- CastleCreations Edge Lite 200 with added cooling tubes and conformal coating. Thanks Joe!
Batteries- Dinogy Graphene (4S2P 3300's). Thanks mark!
Prop- ABC 1823-19-38(2)cll S/B (snowman prep). Thanks Jim!
Driveline- .150 double square cable with teflon liner into Hyperformance outboard stub shaft. Thanks Dave!

So here's the reason for posting the info: It's essentially an off the shelf system. It's proof of what can be done with the incredible equipment that's available to all of us. It's also a reminder how careful we all need to be with how and where we run these things, be safe. Last but not least, it's a starting point and an invite to anyone who might be interested in joining us at time trial events.

Now that's the spirit! I like where this is going.

How does one thread that into a strut being a left hand thread???

Buy the correct tap (5/16-32R from memory, I'll check). Tap threads in the speedmaster flat bottom strut. Teflon lined 1/4" brass on the front side, outboard stub shaft on the back end. Figure out what shaft length you need and have Dave at Hyperformance build you some double square shafts. Outboard coupler at the motor.

Thank you. Answers to all questions I wanted to ask except how you lube it, maintain it? Take motor out?

Motor has a square coupler and slides right off the shaft. Unbolt and remove as usual.

Every run I squirt a 50/50 mix of marvel air tool oil/STP into a hole drilled in the upper 2" of the stuffing tube and a hole in the side of the strut. Both holes are slightly counter sunk to give a good seal to the oiler tip.

Thread the stub shaft out and pull the cable between events. Spray with wd40, wrap in a paper towel and leave it in the hull.

What is the purpose of having such a double square shafts setup compared to using the typical flex cables and collet, etc?

No binding under load.
Thrust applied at the strut.
No thrust load on motor bearings.
Sealed drive line.

ahhh gotcha. I hear thrust load and big drive dog gaps are a bad combination especially for LMT motors and their motor bearings... Is there any truth to this? Should gaps be minimal when using LMT's?

raptor347

No idea. My experience is very limited with LMT motors.
I try to keep thrust loads off any motor/engine bearings.
