hey sp thats funny you mentioned the rrr cause the guy at my LHS that passed on the info to me about metal servos has that same car??I think the reason is that he had a problem when running a metal servo on throttle??
also I thought the G4+ was a limited edition with only 1000 made is this the case or is it in continous production now??
thanks for the info
cheers

guys thanks for replying on the topic of the servos ...

btw, I am just curious, what servos would u recommend ?

Omarko,

IMO, the competition / race servos are a bit expensive but well worth the price and lasts forever. There are budget servos that may fit the need, but they break down sooner and faster. In the long run, you may end up spending more with budget servos because you have to replace them more often

The discontinued Futaba 9550 digital/coreless low profile servo for steering (perfect fit) is still available at online stores, and if you're lucky, at your LHS. This servo is also lighter than a full size servo. This will set you back around $75-80. Lots of G4 users have this servo. It has been replaced by the 9551, which I haven't seen yet because they continue to push back the release date. It is suppose to be a bit stronger and faster.

For throttle, get a good high quality analog servo. My choice is the Airtronics 94357 or 94358.

There are plenty of good choices out there, this is what I use.

guys I just started building the car and on the front diff with 30000wt oil it seems VERY stiff to spin the diff, is this normal? I didnt know 30000wt oil was this thick, the diff spins but with alot of resistance, will this mean the car doesnt roll as freely?

I think i found a mistake in the manual, the booklet calls for 50.70 mm from cup end to cup end for the rear anti-roll bar, one problem, 50.70mm means the cups are uncrews off the rod....



any suggestions?

as long as you are certain that you meshed all your diff gears correctly! yes this is normal over time it will free up I put 50000 in my front diff!

yes this is a mistake I am fairly sure its 46mm!if you look back thru in either this thread or the g4+ it should be there!

The car will still roll freely in a straight even if the diffs are tight. Tight diffs, which sort of acts like a spool, are good for high speed, free flowing tracks while looser diffs are good for small, tight tracks. Either way, you have the ability to brake without loosing the back end.

can someone double check for me?

I dont have a g4+ and im not looking through 500 posts

rc_alan

In one word.... No. and just to keep you from causing yourself more problems... I wouldn't use 30000wt diff oil in the front...

thats what the g4rs kit com4es with is 30000wt, it depends on your track i use a spool on my g4s and a diff on my rs with the different tracks, best thing to do is play around and try out different weights and see what gives you the better lap times or maybe change from a diff to a spool or maybe even a one way??
cheers

Don't worry. The diff's will feel a little 'stiff' and what has already been said is true, you will need to try differnt oils out.

Generally (!!!)

You will use a very stiff oil in front and low in the rear when there is little grip....... ie: 100,000 FT and 3,000 rear.

For a v. high grip track, some seam to go for slightly lower front and higher rear oil......... ie: 50,000 ft and 30,000 rear.

There are many exceptions to the rule. One nalely the front spool. People have used this in both high and v. low grip conditions.

It does help to pull the car around though, especially in low grip.

Hope this helps you.
Ps: In other words. Try the stock stuff in front and rear. It will give you a general feel. Then once you've taken the car apart a few times, try different oils loosely based around the info' above and see how you like it.
