UL-1 Power system upgrade arrived!

[LuckyDuc]

The power system upgrade for my UL-1 arrived today.
Motor: Medusa Research 36-60-2200
ESC: Etti 150 opto

Eagle Tree test data coming soon!

The small Grimracer L38 x 55 prop would be a good prop to start testing with. Be careful Alvinsmith burned up the ETTI controller in his UL-1. Do not use a lot of ON/OFF throttle.

Thanks for the heads up about the Etti. I hope it is beafer than that Perhaps it was the BEC that burned up with his. I intend to use an external BEC with mine as I purchased the higher volt version that does not have an internal BEC. If it does burn up with less than full throttle I know better than to buy an Etti again.
The first prop I intend to test is a grimracer L40x57... it's the smallest I have at the moment. I plan to test an Octura x440/3 blade also, but it hasn't arrived yet.

Dude my etti was the 150 non bec and it didn't last 4 minutes. I would try a xl motor with the 120, then you should be safe.

The capacitor upgrade should help.

The L40 X 57/3 would be cool to test also. Let us know.

What a load of C#*p nothing wrond with the Etti 150 i have been running one with a KB458xl 6s m445 & abc H5 prop no problem that esc will handle your app no problems just start with a small prop x442

Your Eagle Tree data might come in pretty useful for this thread.

Wow! Looks like you started quite a discussion there

Completed Medusa 36-60-2200 install

I finished installing the new power system this afternoon. Everything seems to be functioning properly.

Changes I made from the stock configuration include…
-----------------
-An external 6 volt ParkBEC to power the Rx and servo.

-Installed a Medusa 36-60-2200 motor coupled with an OSE aftermarket UL-1 water jacket. Seems to fit fine.

-Replaced the stock collet with a Kintec 3 piece collet adapter. I kept the stock collet with the stock motor for ease of swapping motors back and forth.

-Installed a 5mm thrust bearing between the motor and the collet.

- Replaced the stock ESC with an ETTI 150 ESC
-------------

Things I noticed during the installation….
The motor shaft sticks out a bit from the end of the motor can. Shown in pic below. I need to keep the wires and lipos clear of this. I may make a cover.

The front of the motor shaft hit the end of the collet, preventing me from closing the gap between the motor, thrust bearing, and collet. I had to add 3 washers to the outside of the thrust bearing to take up the extra space between the motor and collet. No biggy. Pic of installed thrust bearing below.

I also had to trim 3/32” off of the flex cable to get the proper clearance between the drive dog and the back of the strut.

Looks good man!
cant wait for the video..

Looks great, can't wait to see the results. You going to start with an M440 or similar?

[LuckyDuc]

Thanks!

I have a Grimracer L40x57 3 blade on there right now to test with first. When I get done testing that prop at the various strut depths I plan to test an Octura x440/3 next. It should arrive before the weekend with any luck. I intend to also test a Grim 40x52 3 blade to see how it compares to the x440/3.

And... when I get done with those... just for kicks, I have a Grim L42x66, Octura m445, and a Prather S220 to test

You can also trim the motor shaft off if needed instead of adding washers.

duc, my favorite was the 38X55 for speed out of the turns, speed in the straights, and decent temps. nothing was to hot to melt anything after a 10 minute run. another prop that may be really fun for your setup is an X637 0r X642. The EDDI and new motor should take a 6 series prop if you don't get to big.

will there be video on hand cause I'd really like to see this.. good luck man!!

[LuckyDuc]

I think I will order a 38x55 tonight for testing as well. I will talk the wife into manning the video camera when I get a chance to run it.

At Jeff,
I thought about cutting the shaft, but it seemed like very hard steel, and I only have a dremel
