Quick one for you gurus out there....

I have made the switch to Avid Big bore springs on my 44.1

Questions 1: I cant get my ride ht any higher than 20 - 20.5 mm as the avid springs seem a little short, I have also tried Traxxas and Losi lower spring retainers BTW i am using Ghea Upper Collars.?

Question 2: has anyone found a need for a stiffer spring than the Purple Avid (which are .2lb) softer than the standard AE silver?

Cheers

I'm looking for some help from regulars at either OCRC or WCRC in Orange County / SoCal.

I recently picked up a very lightly used B44.1 . Got some help from a team driver at OCRC on the diffs and slipper settings. I dropped a brand new Novak GTB2 ESC and a Reedy Sonic 6.5T into it. The problem is, the car doesn't really feel any (or much) faster than my B4.1 with a Tekin RS and Tekin 13.5T in it. I had another guy at OCRC that used to run 4WD buggy class drive the car, and he also expressed it seemed 'slow' for that much motor.

I left the timing on the Reedy 6.5 alone from out of box, and I'm running a 81 spur with a 21 pinion. I checked temps on the ESC and motor with a temp gun after starting with a 17 pinion, then a 19, and now on the 21. Everything is free spinning, no binding, no bad noises from the gears. I've reset and double checked radio and ESC settings to make sure I'm getting full throttle, etc.

I'm starting to wonder if the issue is my batteries. I picked up a couple Turnigy Nano-Tech 5100mAh 65-130C 2S Lipos. I also have similar (same brand) batteries in my 2WD B4.1, and I thought they seemed really good, especially for the price.

Other then the car isn't as fast as it should be with this electronics setup, I'm having fun with it and it handles pretty well with the stock settings. I'm really hoping some local folks that read here can offer me to meet up with them to help further figure my issue out. I'd love to try another battery someone can offer to see if there is any major difference there before I plunk down a large chunk of cash on one for no good reason. Another thing is maybe swap my motor into your B44.1 to check it out. I have a good soldering iron and lots of soldering experience, so the swap would be very easy.

Please respond here and/or PM me. I'd greatly appreciate it, and am willing to buy your practice or race time that day for your assistance.

Thanks,
Jesse

B44.1 action shot.

Great shot!

John Watkins-I just installed the Avid big bore springs on my 44.1 but I'm not having the ride height issue u are. I'm trying purple front/yellow rear springs with Traxxas 3768 collars top AND bottom. The Traxxas collars slip right over the stock AE spring retainers. I'm using stock pistons with AE 35 oil ft/30 oil rear. I have plenty of room for ride height adjustment.

I just put on the new springs last week and will try the car next Sunday here in socal at wcrc.

What's the reason everybody seems to go harder on the rear and softer on the front with the Big Bores?
I always thought that the best Start- Setup was the stock one, which is rear 1.9lbs/30w/No.1 piston and front 3.85lbs/35w/No.2 piston?

For me, the best "replacement" would then be rear AVID white(1.89) and front LOSI blue(3.8).

My technical knowledge tells me that it's possible to choose slightly softer BB springs, because the small springs got "softer" during driving, because they got more "stress" and had more work to do!?

Am i totally wrong?

usually anywhere from 1/8 to 1/4 out in front and 1/4 to 1/2 out in rear feels the best. BUT the term "fully tightened" is misleading. This does not mean cranked down until the screw doesn't turn anymore. It means tightened until the spring is no longer able to hold the T-nut from moving. BIG difference. As you tighten the screw, watch the t-nut compress the spring. When it stops moving, that is fully tightened. Of course, after breaking in the diff to fully seat the balls and rings, you may need to re-adjust a little.

Where did you order these? ive seen them but up in the air if i want to drop the coin on them.

Thanks Jg,

How much adjustment would you say you have available to you (IE threads available on shock body +5mm?)

I know the traxxas top collors slip over the originals which would give another 1-2mm of play, that may help, but if you are saying you have a bit of adjustment left again, I'm thinking i may have a bininding issue witch is limiting/affecting my rebound.

Let me now how you go with them, Alot of the Team guys havent gone with Avid's on their b44.1 they are still runing LOSI springs and Avid's on their other cars, not sure why?

Cheers

I will keep you guys posted on what i find out.

Unless you got a bum pair of saddles, those batts are great. I run them in my 44.1 and Desc410.

Double post sorry.

I thought about this problem all night. The only thing i can think of is you might have a bad battery or bad motor. The last thing i can think of is maybe your Throttle Epa on your radio is turned down. Good Luck hopefully you get it resolved without having to spend any money.

Tried losi bb springs, orange front, #2, 35wt losi oil front, and white rear, #1, with 32.5 losi oil rear. That combo was too soft. Switched to yellow rear and that helped, and just ordered the green springs for the front.

I ran this set up at Glitch, in az, an outdoor, dry dirt track, lightly dusted.

what pinion should i run with a 5.0 turn motor?

i know different tracks require different pinions but whats a good starting point?
