Hi Guys,
I'm thinking about converting my Trex 700 into an electric beast. What conversion kits are considered the best? What ESC should I use if I plan on runnning 12S 5000 mah 30C packs? The castle or something stronger?

Thanks in Advance,
Bub

its hard to say i would go helidirect which keeps everything stock. i would do hv110 for the price ..jive is high end but also very pricey all goes back to your budget.

I have completely finished my 700e conversion and test flown several times to see how it handled and what the final numbers looked like. I did not run any data logs, but, I don't think I need it. I just went by temperature of motor, esc, and lipos. First of all here is my set up:

700 Nitro Kit
Helidirect conversion kit
Scorpion 4035/560kV motor
CC 110HV ESC
Hercules BEC
FAD 115T Mod 1 main gear
Scorpion 10T Mod 1 pinion
X2 6S Turnigy 5000mAh, 35C lipos
G5 Pro Wide Chord 710mm blades
RJX Flybarless head (modified)
Skookum FBL system
Total weight RTF was 11.4 Lbs.
HS: about 2050 RPM with no load. Under load: down to 1900 RPM.
I am not using the governor yet. I am afraid of using the faulty firmware and burn my expensive ESC.

At the beginning I was flying without the Skookum, but, since I still do a lot of FFF, I did not like the handling of it. It tends to pitch up a lot when in FFF and very unstable hovers when windy. That's why I decided to go with the Skookum. It took care of all the glitches and now I love it.
For each flight I did a series of maneuvers. I am not a hardcore 3D flyer, but, I can pull some maneuvers off. This was my test series: FFF, loops, consecutive flips, consecutive aileron rolls, inverted fight, and a set of tic-tocs. I also did a few punch offs and tried to fly it a little hard. I landed 7 minutes later.

The verdict
Motor temp: 145 deg F.
ESC temp: 110 deg F.
Lipo temp: 90 deg. F.
Voltage leftover per cell: 3.78V

I can honestly say that I am very happy with this conversion. It has a lot of power and torque. It maneuvers very quickly and it is very efficient. I could probably get another 30sec to a minute more of flying and still have the lipos in a safe zone. But, I rather give it a larger buffer zone. At this point, I don’t miss nitro. Especially the cleaning part and the extra stuff you have to carry around.

For this project I decided to go on the budget end and I don't think I spent too much on it. Aproximately $2000 for everything, I am talking about all electronics (that is rx, servos, motor, esc, bec, 4 lipos, gyro), blades, new canopy, and FBL system (head and SK360). Off couse, I bought most of it used. I would go with Helidirect for the kit, they have a cheap kit ($75.00) and also a nice economical flybarless head.
