That tire above with the fishing line is it a truggy or buggy tire its hard to tell? I was thinking of using the new pro-line vtr xtr 4" wheels and tire combo and do the fishing line mod which tire do you think would work the best.

nitrostarter 08.21.2009 01:56 PM

Those are Buggy Crime fighters in the pic.

I think the new VTR's will be the best truggy option since the shortest sidewall.

Rivermaxx 08.21.2009 01:59 PM

Yea I was thinking the same thing I wonder if I could do the fishing line mod on the vtr"s.

DwightSchrute 08.21.2009 02:01 PM

it's a buggy tire. here's where i buy all my treaded pre-mounts:

http://stores.shop.ebay.com/Supra-Sales__W0QQ_armrsZ1

the thing i like about this store, is all their pre-mounts are always perfectly balanced and they are glued very very well.

I've used the fishing line method on these as well and it works great:

I think, ideally, the HPI phaltliners are the best for the truggies/MT's, but if traction is an issue for you like it is me then the Supra truggy yoko's are great with the fishing line technique.

also, i've heard mixed reviews on these, but might work for MT foams. it certainly has the size. i just don't know how good the glue is.

Dwight is obviously on the right track to hitting the 100mph mark. Follow what he is doing and pic his brain as much as you can, sharkattack.

Also Shark, if you want to avoid doing the 8s or 10s setup stick with the MMM, 6s lipo, and get a 1521 or 1527 Neu motor. there are a bunch available right now on offshoreelectrics.com great prices too. if you run 6s just choose a motor with about 2000kv. this will put your motor in the 50k rpm range which is close to max of the motor but not so fast to damage your motor. if you choose this type of setup the rest is gonna be up to gearing and aerodynamics and durability really. good luck.

thanks for the info and the pictures dwight, is that the 2.0 version or just the 8ight? i was looking at the 8ight 2.0 as a starting point. did you get the motor here on rcm? not sure if i should get the one with the motor and stuff or the one with out cause i was hoping to sell the nitro for some extra cash to help fund my project. im not sure yet still getting info and research on were i should start.

well if i can't find a motor that can handle the 8s or 10s or even 12s i won't be able to go that route. we'll see.

Rivermaxx 08.21.2009 07:37 PM

The esc has to be able to handle 8s 10s or 12s first and they are pretty pricey. I really dont think you can put that many batts on that chassis can you?.

All of the 8ights i have, i got off of ebay as nitro rollers. I just got #6 the other day. they were alot cheaper than going the e-route and i could build them the way i thought they should be done.

check out this thread on how i approached the build if you're interested:

http://www.rc-monster.com/forum/show...07&postcount=9

That particular 8ight was a 1.0rtr i had made into an electric conversion, but i have the 2.0 as well as the 1.0 race roller. the differences are all so minimal, any of the platforms are gonna be great to use and all of the parts are interchangeable.

I got my neu at offshore. they've been on sale for a few months now. As far as going 8, 10 or 12S, it's all a choice of effeciency vs effeciency to get the same speeds as 60K is gonna be the limit for any neu to last.

for me, it's a heck of alot easier to get a 1515 1.5 D to do 90+ on 6S than it is to mess with a HV-110 and pistix with a lower KV motor and have to carry all the extra weight. in the end, you have to get as close to 60K rpms as you can without burning it up so i decided to go with a higher KV motor with less voltage. The lower KV motor with higher voltage will be more effecient, but to me it seems like it could also be problematic as using mechanical brakes and fitment will become somewhat of an issue.

For me, the 1515 1.5D is plenty of motor for me. It'll get you right around the 90-95mph mark if you have a good long stretch of road to run on.


Edit:

Still, i think the ultimate speed package is gonna be the 1521 1D (2900KV) on 5S. when i dropped my friend's in...my jaw hit the floor. I'm ordering my own from castle. :gasp:

I just noticed offshore has some 5mm in stock now. Also, if you go the 1521 route, this is also a good idea to use:

The IMEX tires just like the OFNA buggy foams are not glued, they are 2 sided tape.

The buggy tires have held up for me at 100+ with no big issues.

The IMEX in my opinion are horrible!! Big issues are the rim is very weak, has alot of wall flex and the IMEX is 14mm hub, not 17mm.

good to know. i was close to buying some of those imex foams to test out on my twin monster mamba e-maxx. Now i'm glad i didn't. :yes:


i think i'll stay with the phaltliners for my MT. they have produced the best results for me so far.

wow thanks for the info now i have a starting point. and good lock to you on your quest for 100+.

sharkattack99 08.25.2009 07:59 PM

oh for got to ask what is a pistix? and why would i need one?

it's an adapter that makes it possible to use aircraft escs like the phoenix hv 110 that can handle much more voltage.

basically, the pistix translates the throttle signal of an aircraft (which is different from a land esc) to a land signal. you need to use manual servo brakes though as an air brake translation gives little more than the feeling of a drag brake.

jayjay283 08.26.2009 12:19 AM

I have a pistix never used, one of his last. Though he said he was going to make a pistix 2.0 which would make mine turd. Its all yours if you get this going. Means I have to get up and go to the post office. No small task for me. Lets see some progress and if you need it its yours. RCM <~ makes it happen

_paralyzed_ 08.26.2009 12:33 AM

many newer plane esc's don't need a pistix, they just calibrate for either radio type. cc hv's need one though. hobbycity's don't........
