Latest new high end Receiver now have built in by pass capacitors circuitry to help with the resonant frequency noise, especially those 7 to 10 channel heli receiver, which u need this circuitry on more then 3 channels receiver.

Default Only If you are into the extreme of finding out the Glitch.

I have a glitch monitor or counter that i made my own to count how many hit i got and to troubleshoot the problem area on my R/C. Place it on my heli but not my car. I think u can buy this online somewhere, i can't remember where, its pretty expensive though for about 50~60 bucks. Most of the hardcore heli guy have it on their Heli for prevention purpose.

how much run time are you all getting out of your serpent receiver packs? i have yet to run mine right down, even during a full day of racing. seems weird considering it is a small pack.

Its all depends on what type of Servo you are using. If you are using High torque and high speed digital servo, then it drawn much current from your battery.

Assuming you have 750mAmp for your battery, using 2 Digital servo like S9451, personal transponder, use a little of drag brake, you have about 4 runs (6~7mins each run) before u need to charge your battery to be safe.

maybe it is because i am not using digital servos, do not use a personal transponder (use the tracks) and don't run any brake drag.

nizee, are you sure that is all you are getting out of a 750 pack? I run my car for well over an hour on my standard Serpent pack. I have run 45 minute mains without recharging, and still had plenty of juice left. I run an analog servo on the brake (since the digital ones burn up when using a healthy dose of drag) and a digital on steering, plus personal. Of course, being "safe" has never really been part of my battery planning, but I have yet to run a pack down to where I can not control my car.

I know this is off the current subject, but what engine's do you guys run in your 705's?...I'm leaning towards a NovaMega.

What .12 engines do you run and why?

Thanks in advance!!

Fmolzer,

What i did was after every run, about close to 10mins, i charge my battery to find out how much current drain. The charger indicate i've about 120mAmp juice put inside the battery. Multiply by 120mAmp with 4, u get abt 480mAmp, minus 750mAmp, u left with 270mAmp, that 270mAmp usually are my safe zone, just in case. As i saw couple of guys lose control as their battery went low. Also, battery full capacity usually don't go 750mAmp fully charge, even though the label indicate 750mAmp. U could go longer run then that. But both my S9451 really drain so much current. thinking of changing it on the trottle.

I'm running MR-12 and soon the Pixy, still waiting for it to arrive.
Why MR-12? Because from all feedback i;ve heard, it such a good speed engine.

I was deciding on Nova or Pixy sometimes back, but finally pick the Pixy. Why? Because i got a better deal !

You are right, the math is there... but, my pack still easily lasts for an hour of runtime. Again, if a draw say 100 mAmp per 10 minuts instead of 120, that would put me in the ballpark. From a completely drained battery, I normally get about 710 mAmp, then I peak it once before a long race and put another 50 or 60 mAmp in it before it peaks out and that does the trick just nicely. I find it hard to believe that I would draw a lot less than your car considering my very enthusiastic drag brake setting.... but maybe...

Believe me it surprise me too. But then again, i forgot that i've that voltage monitoring device that turn an arrays of LED, that i made my own, that consume some current. I normally get around 700mAmp fully charge.

I run the Novarossi 5-port Turbo in my 705.

I looked at the Pixy for the 3-port class but I have heard they are not all the hype and that the Novarossi S3 is better money value over the longer period and easier to keep running.

As for batteries, I never use anything above 600mah. With 2 digital servos and a personal transponder these will run a car no problem for a full days racing (4 quals of 5mins, 1 final of 30mins and probably 6 tanks of fuel for track set up testing throughout the day).

Since we're on receiver battery packs, I've always been trickle charging my Serpent battery pack. At what amperage do you folks fast charge the battery pack at?
