Hey there all
Picked up my new car just this last week.... new to on road electric. Always been a nitro on road driver. But friend persuaded me to join in this year.
Looks like I missed the outdoor meets so looks as though I'll be hitting the carpet soon.
Know nothing about how to set up electric or anything ... so should be interesting!!!
Feeling like a rookie all over again :-)
Just building the car now. Need a body and maybe a servo. Low profile one... which would you guys suggest?
Looking foreward to racing again after almost 2 years away!!
(Well ... 18 months. Lol)
See you on here again soon.

Really? Not the smaller low profile ones? Well I'll see what I've got. I haven't looked up those servo's you mentioned but do you go just for speed on the? I wouldn't have thought you need too much power on these for steering?!
Thanks for replying though

You mean mini servos like used in 1/12th scale? I believe Josh Cyrull tried that with some success. I however want weight up front to counter the motor and amount of battery opposite, and I do believe the servo drivetrain is stronger in "normal" sized servos. I like to have min 100oz/in for steering and no faster than .10 seconds/60º of travel and no slower than .15 seconds/60º.

Hey,
Thanks for the input Rezen'. Not really finnished the build yet so not had chance to see the weight distribution. But I understand what your saying.
One thing puzzles me about what you said though...... "No faster then 0.1 secs? Why? I would have thpought faster the better, isn't it?

I also have a question for you experienced MI4 drivers...
The double cam steering..... as apposed to the single.
I've heard the double gives a more progressive steering and is less aggressive.
I will be racing on carpet I guess so would I be best to stick with the single to get more steering?
Thanks for your input.

I feel that the double bellcrank steering is more linear, less aggressive around neutral, and better/easier control in tighter corners. That can all be changed with the servo to steering link, as well as the ackerman links.
I do not like a super fast servo, as they cause my car to do EVERYTHING my hand is inputting. .1 second/60º of travel is still very fast, but going to the .06 versions is just nuts. I used to run those in my 8th buggy as well, ended up dropping them all for .1 second versions. Its all taste and feel. At least if you have a higher end radio, you might be able to slow the servo down. It was just much too twitchy for me, and I love a twitchy car.

Is there another brand of spur gear that will fit the Mi4? In 48p, Schumacher doesn't seem to offer anything between 70T and 85T. I'd like to get something around 78-80T. Just enough to get me down to about 3.6-3.7 with a 37-39T pinion. I have no trouble hitting that FDR with the 70T pinion, but it moves the motor pretty far back compared to a larger spur. They make a 106T in 64p, which is the perfect size, but I don't really want to go 64p. I like how easy it is to mesh the gears with 48p, and haven't had any problems with grit.
Any suggestions? Xray maybe?
EDIT: Hrm... Their UK site lists a 74T 48DP for the Mi4.
