How are the Rx8 & T8's holding up?

rotor breaks a 4s or 6s?

we all use 5S mostly 1700kv and one 2000kv motor

I was using a 1700kV buggy motor on 5S.

I was at the race meeting where Marvins rotor seperated (again),it really is quite upsetting to see someone spend a lot of money on something he really believes in (electric over nitro) green issues and noise.When he built his first electric buggy,most of the people at the track we race at,really took the mickey,'the motor/esc bound to break/short/burn/explode,that sort of thing,but he stuck with it,to the extent that a few of the racers were starting to consider that he may be right in what he is doing,but with these continual breakages/problems he is beginning to get very down-hearted,which is a real shame,because this hobby needs people like him if it is to grow.He is now at the stage where he just does not trust a Tekin motor to survive a race,but because of money shortage he will have to stick with this motor,instead of,i suspect,buying a neu for his buggy,a real shame.

I'd like to know his full setup: Motor, gearing, battery, car, weight of the car,etc.

Is it possible to get a full refund for a RX8 1700 Truggy set which I bought from amain hobbies this month ? (The ESC is on the way to tekin for replacement)

I don´t want to put this set in my car anymore.

break more easily buggy 2.8" or 3.0" motor truggy?

motor 3.0" should be stronger because they are longer! or not?

While this is rare it would be quite dissapointing for the consumer to be sent a new board only to find out that his unit is still non functional after the repair.

The most common part to have a cold solder joint is the large black piece suspended from the lower boards. It has two joints that attach it to the board and must make contact. While flowing them again isn't overly difficult it still might not be the only issue.

A broken unit is a lose lose for both sides. However we're obligated to make it right and we're doing our best to turn the service items around as quick as physically possible. We have people working on the weekends and at night to make this right for the customers experiencing the problem.

That can be one, yes.

I was running an XB808, weighing in at 3.7kg.

Motor: Tekin T8 1700kV Buggy
Battery pack: Hyperion VX 35C 5500mAh 5S
Gearing: 42T spur, 15T pinion, 4.3:1 in the diffs.
Connectors: Direct solder between the motor and ESC, 6.5mm gold tubes between the battery and ESC.

The track is medium-large, with a few sweeping corners. EDIT: It is mainly dirt, dry and dusty - low grip. /EDIT

I use Mike's motor mount and one of his 15T pinions. In fact, the combo was bought from him at the same time as the motor mount and pinion.

EDIT:
ESC settings:
Punch Control: 60% (I believe it's around that mark. I set it to 70% on my hotwire, then lent it to someone else, so reduced it by 2 LEDs on the ESC)
Timing: 0
Cutoff: 5S
Throttle Curve: Linear

I haven't touched the other settings if I remember correctly.

I'm just not sure that the 5s 1700 setup is "ideal" but it should still work.

That's a fairly heavy car at nearly 8 1/4 lbs. My car is weighing in at 7lbs 9oz's but again, it should still work.

What rotor is in your motor? Original or the new style?

On the track how does the car feel? Do you have too much power, is your car a lot faster than other nitro buggies?

[bryan]

I HAVE A BRAND NEW RX8 ESC. ON EBAY NOW. THE ONLY REASON I AM SELLING IT IS BECAUSE THE 1700KV T8 WAS ON BACK ORDER WHEN I WANTED TO PURCHASE IT.MY LOSS COULD BE YOUR GAIN. JUST THOUGHT I WOULD LET YOU GUYS KNOW

I always thought the x808 was a light buggy,certainly no where near the weight of a Truggy or MonsterTruck,are you saying there is a weight limit?
The rotor in Marvins T8 was a new V2 rotor,which you sent to him after his original V1 rotor failed.As for track running,yes the car has more initial punch,but is no faster then the nitro buggys down the straight.

Out of interest, why do you say that 5S 1700 is not ideal? It was recommended to me my many of the members here, as well as, if I remember correctly, Mike. Obviously, as the manufacturer, you're opinion/testing is perhaps more valid, but I was just wondering why?

I know it's not the lightest car, but it's only a little heavier than a nitro D8, and they don't get any more engine failures than other cars.

I have the V2 rotor in there, which was sent to me after my V1 failed.

With the 60% punch control, my buggy is a bit faster out of corners (as is expected really), but is a little slower down the main straight than the nitro buggies. Only by a very little amount, like 1/2 to 1 mph.

I turned the punch control to 60% after my original rotor failure, as I was asking what were the best ways to eke out extra run time. I turned punch control down to 70% first, then to 60%, and I find that I can't really spin it in corners any more. My 808 has got back all the driveability it had when I ran nitro. (I used to have a nitro XB808 late last year).

I now am driving smoothly, and, other than on jumps to correct the flight, do not blip the throttle. I just slowly build up the revs through a corner, and rarely brake into corners, preferring to roll into them instead.

Obviously, on tighter corners I will brake, but I do let off the throttle a coast first.

Hi mate,

I bought one of these 2nd hand off a forum user, and have a good feeling this is what has happened to mine... if i send it back, will the repair incur a cost to me other than postage??

What's the addy to post it back to for repairs?

cheers =)
