nitrosportsandrunner -> Cat 5 Tornado! (8/21/2012 1:51 AM)

I have my Tornado epx pro ready for 3s lipo power.

I upgraded the shock towers to the billet alloy ones.

I added 2 heat sinks to the motor.

I installed a 8E fan to blow onto the motor. Its mounted with servo mounts.

I moved the ESC to the top plate, and re-wired the fan to be powered off the reciever.

Last, I put on traxxas 2.2 rims with proline dirt hawg tires. These do decent offroad, and wont fall apart when used on pavement.

I will be testing it with the new skylipo 3s 5000mah hardcased pack that just arrived tomorrow. Cant wait to see the speed. I will also check the temps.

Ok
tested the tornado today on 3s.

Speed was amazing. I even pulled a wheely!

I do have an issue tho. Im not sure why, but a kept loosing either steering or throttle. I think its cause I was trying to power 2 fans off the reciever.
I think the bec on the reciever couldnt handle the draw.

I could keep my finger on the motor/esc...so temps never got more than 120-130.

Its possible the ESC just cant handle the power. I know I have run 3s on this system before....but the sky lipo Im using now is a 60c burst-30c constant. So the lipo can put out more punch than ones Ive used in the past.

The larger tires also put more strain on the motor...thus more draw.

I may have to upgrade the BL system. But Im not giving up on the little ezrun ESC just yet. I have a few ideas to try still.

Anyway...watch the vid. I never even gave it 100% throttle!

well, did more testing last night.

I wired up the 2 fans to a seperate 2s 1000mah lipo pack (rx pack)

I didnt have any glitching, but then I only got to do 3-4 high speed passes before I heard a bad sound.

It sounded like the dredded spur gear strip sound.

But when I pulled the cover off the spur gear was fine (I had forgotten it was hardend steel)

The pinion gear on the other hand had only 2 teeth left!

Ive been in the hobby for 7 years. Ive had some pinions that were brass which got worn down over time, but this was the 1st time I have seen a pinion gear have the teeth sheared right off!

That novatech 3300kv motor on 3s packs a punch.

The buggy pulled a wheely at over 25mph! The rear of my wing has road rash! (it acts alittle like a wheely bar...lol)

So ill have to wait till a new pinion gear comes till I can know for sure if I have sorted out that glitching problem.

I talked with a buddy who agreed that the ezrun esc blinks red if it overheats. I think that blinking green is what it does if it doesnt have a RX signal. So I think the fans overloaded the BEC on the rx and thats what caused the servo and throttle to cut out on me.

When I get a new pinion gear Ill drive it enough to know for sure. I will also take some temp readings, tho Im pretty sure they are low enough.

I will also double check the punch control and braking force on the ESC. I had them set a tad lower when running 2s (From stock) but Ill need to put them down more for 3s.
