There will be a pro comp version available. all bling. I have an all bling on road car coming. The models aren't actually store ready. Nutech just did the Nuremburg Toy Fair this weekend past. Production models have been shipped to distributors. I am expecting a few things as this is a pre production model. I allready told Scott at Vancouver Hobbies to set aside a full set of aluminum dif cases for me. Thing is parts and bling are cheap for this model and the mfg is making a ton of goodies right away. I have talked with the guys at Nutech, which in today's world is rare indeed, and they listen and write back. I like support and I like input. The bash videos showed they were tough, but support is important to me too.

Well I get up early today, we have a bash day planned. I prepped last night and figured out my servo problems (am running 2 castle bec's in parallel to power these hungry pigs.. going to hit the mouse button in a couple minutes and buy new servos) and now it's raining outside... arghhh I wanna play with my new toy. I will pronbably hit a gravel field and just go get wet.. can't take it. probably a trip to the lhs is in order too (maybe they will have some good servos and another bec to replace the one in the vw.

ok so my foam looks hack but it serves it's purpose :P I never claimed to be able to keep an rc on it's wheels all the time. I want to test it for durability

Doesnt look hack Baz,fookin' great idea!

good idea pipeous quick and easy mod and cheap

Took mine out to get it run today but the servo problem is still there. I got a video of it running anyway, but just sitting still. It tried to run away when the servos started tweaking so I killed it and did a video to show what the servos are doing... and it's doing it with all 3 radios I have. Am going to put this GWS servo I have in the throttle first and try it out. if not then I order some new ones tonight.

Pipe sounds awesome. Everyone around said it sounded like a dirt bike. I started it outside here a while ago and got the same. Bummed I couldn't drive it, especially watching my bud rip it up with his baja, but we took the electrics out on the bmx track. I'll put a link to the vids when my bud uploads them. for fun I tossed the 3s lipo in with my 5700 and was getting some serious airtime. busted 2 body posts, ripped the body up pretty bad and bent the rear shock tower. not bad for a day of serious abuse (that little ofna is one tough truck)

Well it was my throttle servo. Long story short, I have a gws to put in for now, and it's working fine with one bec. I should get to drive it. I'll get a couple 5745's to toss in though next. Scott... hey Scottt. put aside 2 5745's for me... in fact put aside 4 cuz I don't trust those servos much now and I have another car coming... LOL

Pipe, have you tried it with out the fail safe? thae fail safe used to make my servos glitch
so got rid and use the inbuilt 1 on my 4pk.......

[Trip]

Cool buggy, I really like the pipe! It looks like it's really tucked in there.

I tried 3 different radios, and combos. ended up being the throttle servo. I had to do a detail today. ended up doing the full meal deal since it was sunny. had 4 hrs sleep, did that, have to unpack the car, eat, get 2 hrs sleep and go back to graveyards for 3 nights... this mild winter is crazy man. I don't usually book details until march april. booked 3 more jobs today alone. one day off a week is killing me... the graveyard gig we said we want more money. if not we said get another person in then to take up slack... I only wanted 2 days a week. this 3 on 3 off rotation is driving me nuts. body doesn't know when it's supposed to sleep anymore

ok enough ranting. tomorrow I will fix it. I jusy have to hide from the neighbour that wants her stairwell and hallway painted hehe

Both servos are toast. I did more testing today and found they draw enough power to make the light blink on the bec. I can put the gws on with a servo horn. lock the horn down to overload and no blink.... and the servo now out gets warm on the bottom in seconds. so it's not worth playing around... got 2 5745's for 140 cdn shipped. not worth chancing my new toy. I'll just get the vw back up and running. I have other toys to play with while I wait

Well I got kinda lucky today. I really didn't feel like working tbh. I went to my appt and they weren't home. Usually when they go out they leave the vehicle in one or 2 spots. I know where everything is and the dog is awesome. Guess they forgot... I never make it to the one hobby shop out there so decided to stop in.... they had 2 Hitec 5745 mg's in stock. Yoink (I'll save the other 2 I ordered for the GT5R).

I haven't done anything to the steering rod as above but I wanted to say that the stocker actually have to be careful. Now that I have full steering, the plastic rod end closest to the servo saver actually hits the dogbone now. I installed my Hitec 9745 mg's and just cut one of the aluminum incl servo horns in half for the steering side. at full epa it goes to just about knuckles hitting c hub. the Hitec servo horn is actually a hair longer than stock too...

So to go and play I am going to leave the stock one in and just shim onder the metal part of the ball end to lift it a tap. there's still a fair bit of thread left on the bolt anyway. If you are still running the stock steering rod, then I would look close. it actually puts pressure on the dogbone so for those that bent them it might just be for that reason


You can see what I mean in the pics here.

looks nice pipe.

how did the steering problems start? is it because you want to run 2 steering servo's? Im trying to get my head around the problem but a little confusing which isnt out of the ordinary for me.

or do you think there is some kind of design fault there.

[pipeous]

In the 2 videos above, the first is just idling. The second shows what happens to the servos. I am using a Castle BEC set to 6v. It can handle 10 amps. I use them in both my FG's and had one in the Redcat, The Firehammer etc etc... I like to use 3s lipos. They just last so much longer and no memory... anyway

when both servos get used at the same time, the draw was so heavy that even 2 bec's in parallel could not provide the power and they started twitching. I pulled the throttle servo out because I thought it was just one and had a gws to toss in. but it still did it with one bec and the gws. it didn't glitch with one servo but the bec light would flash....

it has zero problems with 2 Hitecs... and now that I put a flat nut under the steering rod, the plastic ball end now goes over the center dogbone and I have full lock. Until my cvd's arrive I increased the camber (well technically decreased I guess as it's now got about 2-3 degrees negative camber) and put half an earplug in each outdrive in the front. that was a fairly tight fit.

so if you get a Nutech, I would suggest pulling the servos and replacing them right away. I will just wait until tomorrow to get out as I had some other crap to do (and I wanted to watch the Canada vs Swiss hockey game. Swiss have a great team man and Hiller was amazing in goal for them).

[sperera]

thanks for the info pipe, if and when I get one I would change the servo's stright up, always do with the gassers.

u think one 5755 would run the steering ok?

looking at the pics I can see that steering arm would hit that centre driveshaft, im guessing you just tunred the EPA down to overcome this?

[pipeous]

there was a lot of extra thread on the bolt, so I just added about a 2mm flat nut under the ball end on the servo saver side and now it goes over the dogbone. problem solved. I'll figure another linkage later without the bends.

I'll charge up the camera battery shortly. make sure I get some video. I'll just be hitting a big parking lot tomorrow. it's a hockey rink and never anyone at the one end. city guys have a fenced area they store stuff, otherwise it's a huge lot
