Hey guys I just bought a new 450 sized Beam E4.
I have a Futaba radio\
Futaba R148DF Receiever
Futaba G190 Gyro
and a hightech servo for the Gyro.
I need a speed controller, a motor and the common servo.
where are the suggestions for this model
the only suggestion I see is the pinion recommendtion
for 2500 kv, 3000kv or 3500kv motors.
I would appreciate any help or suggestions.
My skill level is some where around beginner but I
have an extremely talented expert flyer to help me
fly. so what ever you guys suggest I would be grateful.

I second the Scorpion HK 2221-8 V2. I would also recommend the Jazz 40 speed controller.

To hover is divine, the alternative is rather PLANE.

Advantage has the Tahmazo 40 and 60 amp ESC's.

The cool thing about them is that you can get a small handheld programmer that allows you to program your gear ratio and then "read" the rotor rpm of your last flight so you can adjust your throttle/governor or gear ratio - it makes tuning your model easy. The 60 amp is really small as compared to the scorpion. Advantage has 10% off everything this month and has free shipping

+1 on the Tahmazo ESC. I have been abusing the 40 with a Scorpion -8 for several months now and it has been working flawlessly.

It is compact for it's AMP capacity and whether you fly governor mode or not you can check the max headspeed rpm from the previous flight.

Unlike the CC Phoenix ESC, I can put it in throttle hold and not have to worry about the slow spool-up when taking it out of throttle hold. I still haven't been able to get that to work well on the CC.

+1 on the Scorpion -8. I run a -8 with a Jazz 40 in one 450 and a -8 with a Jeti Spin 33 in the other. Jazz can't be beat if you can afford it, smoothest spin-up and best governor, although the Spin is pretty effective and a lot lighter. It can not hold the headspeed in governor mode the way the Kontronik does, but I like the way the Beam flies with as little weight as possible in the air.

I ended up with the Scorpion 8 and the Tamanzo SC with the programmer.
Fired it up tonite. Just have to do some little things and it should fly tomorrow. I used the 11 tooth pinion.

Scorpion HK 2221-8 V2 with the Scorpion 55A ESC, make sure it is a V2 ESC as they come with the IR programmer and have more Heli related features (soft start etc).

Stick that in with a 14T and your good to go

Dont bother fitting a Jazz, although a very good ESC, it is expensive and will not meet the current spike needs you might encounter. Been there and made the jump to a Scorpion. The Jazz was a great ESC a year or so ago, but the compatition have now caught up

That said, I have NEVER overamped my Jazz 40 (plenty of overhead), it come down only mildly warm after back-to-back-to-back flights, and has a governor that is still best in class. The start-up is also smoother than any other ESC I have seen or used to date.

You may not know if you have "overamped" your ESC unless you were measureing the actual current drawn with something. I was suppicious of my ESC as I had some incidents of the heli falling out the sky for no particular reason. So stuck an eagletree logger on during flight.

My Jazz was pulling up to 59.35A, which I am sure you will agree is well over the max safe rating in it's specifications!

http://www.rcheliaddict.co.uk/f124/...3112/page8.html

Of course this all depends on your pinion, motor, throttle curve, pitch curve etc.

I think the castle creations and scorpion ESC's as well, there soft starts are just as good.

Like I said, the Jazz was the best (why else would I have bought one) but I dont think it is the leader anymore on a bang for buck basis. YMMV

Bang for buck, I agree, it's a cadillac and a bit on the heavy side. I log many flights with the Eagle Tree V3 and can safely say that the Jazz is not struggling - many run it far beyond the 40A continuous for years with no issues. They are understood to be conservatively rated and the BECs are top notch switching units that require no external BEC to run your power hungry servos.

The Jazz is an excellent ESC and they rate them conservatively. You have to look at the average amps going through your ESC and not just the peaks when looking at log data. I bet your average amp draws were nowhere near 59A. Remember most quality ESCs amp rating is for continuous amp draw. Your usually only hitting your peaks for fractions of a second.

I have a Jazz 80 on my Logo500 and have logged peaks of 120A but if you look at the average amp draw it's about 45A.
