You know your probably right, I started to have him change the way he stood on the drivers stand ( he stands with his right shoulder facing the track) but a couple of the fast guys at the track said to leave him be , if he is comfortable he's ok, and what did he do, finished 1st in spec slash and 2nd in monster trk class for the season.....lol, we didnt race for points last year in buggy due to him being new to it, this year he will be running both buggy and mod corr trk, I should just let him drive and just watch and pit for him.......lol

My son who is 7 does a lot of bashing with me and my freinds. He is driving a Savage with a Mach .26SS. I tried giving him pointers and he would get frustrated with me and not want to play so I just left him alone to do his own thing and now I swear he drives better than most of my friends. I can ignore him and know he isn't going to run over me with his truck ,unlike some of my friends. LOL!

thats defiely true if you run hard clutch springs, you do have to blip the throttle i know i did when, i ran the stock losi eight clutch setup.

when i blip the throttle it seems slower, espially running buggy lol. now for truggy yea i can see, bliping the throttle. a bit to get it to rotate. but yes if the low speed isnt to rich, you can be smooth and fast.


i learn from running electric than nitro ,.so im really used to being smooth on the throttle.

i do not blip the engine at all. i let my car do the work. let the car roll into the corner. slowly start to apply throttle from the center off. if your engine, car, and clutch setup right it is much faster. and you will get much better runtime per tank. watch and see if tebo. cav. ect blip the throttle..

Someone put the same frequency in their car, (which was also the same as mine) to see how I moved my servos while I was driving

Interesting, does 2.4GHz allow frequency spoofing?

About the topic:
Its called Pulse Width Modulation, the theory is that you can produce the same resultant rpm using multiple pulses of throttle by varying the frequency of the pulses, ideally these pulses should be all of same width. Thats how it is in electronics. I think this method works pretty well with nitro motors but it may fry the esc if you do that with brush-less motors.

yea but what clutch springs was he using, if its a hard springs clutch setup than you kind of have to blip, the throttle a little bit.

I think that type of throttle control would be more like amplitude modulation. The speed that most drivers blip is fairly constant. The amount the driver pulls on the trigger is what they vary. (amplitude) The blipping you hear when the pros do it is not a straight full on, full off blip. They vary the amount they pull and keep the blip rate fairly constant.

But I do believe PWM is the standard method of internally controlling speed on our speed controllers. At a constant half throttle pull, the ESC is going from full on to full off 50% of the time.

Now back on topic, I’m thinking the blipping is to keep the clutch engaged. When you race a real car, I never see them coast in neutral they are always in gear.

I think blipping is done to keep the car settled , especially going into a turn if you let off & don't need to use the brakes it seems to unsettle certain cars unless you use a little throttle . Going out i think is done to keep the clutch spooled up . I have noticed that it seems as though some people blip it cause they may be paranoid the engine might stall . My son had an engine that we fought flame out issues for a couple races , now he has a habit of blipping to keep it from stalling . I found after 10 years of racing motocross if i tried to make big changes with my son it messed him up so if your son is doing well i wouldn't make to many changes . Sounds like he is doing pretty good.

It looks like he is blipping mostly right before he enters the turn, either from letting off to soon or? And then just as he's exiting the turn, possibly to engage the clutch, but I didn't see him blip at anytime threw the straights....wow he can drive.......
