Kemo, if I had to choose one thing to have on the car that is an option on an FG or the HPI, it would be alloy engine mounts. The torque these motors pull twists the chassis like it was a candy cane. Alloy engine mounts are absolutely essential.[quote]
Are you sure? i don't think candy canes can be twiseted very well. They just break![sm=lol.gif]

RE: 1/5 scale redcats
The buggy body is not ready yet but the moment I see one I will post a picture of it.
Regarding the gears, engine mounts etc, when I actually get the samples in my hands, I will be sure to fill everyone in on them.

RE: 1/5 scale redcats
Here is something rather important on picking radios for these... this is directly quoted from Foxy's guide to 1/5 scale vehicles.
HPI appears to be using the trs80120 radio... if only the TR80127 came in 75 mhz!
ORIGINAL: Foxy
Radio, servo requirements? Failsafes?
Gassers don't get on well with the old 27mhz AM radios. The 27mhz band is very close to the frequency of electrical noise naturally generated by gas engines when running. Avoid 27mhz.
*40mhz* FM is considered minimum requirement, but in this age of DSM and FHSS (2.4ghz crystal free systems), there's no excuse really to spend $1000 on a car and skimp on a cheap radio. *(40 mhz in europe, 75mhz in North America)*
Go for a Spektrum, Nomadio, Futaba FASST or Airtonics FHSS system, if you have the cash, it's well worth it especially with a big fast car, to know that you are not going to be interfering with anyone, or have any glitching issues. 3ch radios are normally required either sooner or later for gas cars, though that does not apply for an HPI Baja 5b which will not be raced (there's no slot for a third servo on the car, and since not racing, no transponder is needed), but most large scales come with a third or even a 4th servo slot, for dual servo steering, or for additional disc brake systems, so 3ch has become the norm.
Servos (especially for steering) are obviously much larger and stronger than their standard size counterparts. Most servos available in the 1/4 size servo market are adequate for the job of steering a stock gasser, and the differences are whether you want to get a faster servo, or a digital servo, or a heavy duty metal geared servo, etc. There is one steering servo that does it all for a reasonable price, it's a large scale digital servo, with 16kg@6v holding power and 0.10sec/40deg/6v transit speed. It's called the Multiplex Rhino Digi4. Great servo.
For the throttle, some models provide only a small servo slot for a standard size servo. Some others give you the option to use large scale servos for throttle/brake duties as well as steering, but for most purposes, one strong (200oz-in or more) standard servo is adequate to pull the brakes and operate the carburettor on one of these cars.
I guess it goes without saying that servos for these cars are an important item, due to the size and weight of the car, so don't skimp here. Good servos will last you, bad ones will fail on you, and failures in control can be very expensive
Most RTRs come with rubbish electronics, which should be upgraded immediately.
Failsafes are essential for gassers, more than any other scale. If you have a 30lb truck run away from you at 40mph, you are not gonna be able to catch it, and chances are it will either do serious property damage, or worse, put someone in hospital with multiple leg/foot fractures. I can't stress enough the importance of at least a basic failsafe, and ideally one that can cut the engine as well.

RE: 1/5 scale redcats
Got a few PM's asking to compare the size of our 1/5 with a regular vehicle.
Here you go:
I also updated this page: http://www.redcatracing.com/15scale.asp
Got the two samples in as you can see, but I cant bring myself to get them dirty. I think I will do that on Monday.

RE: 1/5 scale redcats
I have some things planned, but yes there will be pre order options.
I should have everything finalized in about 10 days, which will include pricing, exact dates of availability and hopefully even a picture of the buggy with a body on it.

RE: 1/5 scale redcats
Dude Darin those 1/5's look sweet. I never realized how big those thing were since i have never seen one. You did good on getting those bad boys!!! Will there be a bigger engine upgrade?

RE: 1/5 scale redcats
ya i think they are gonna need a the 26 cc engine to get them going fast enough to clear the jumps i thought i heard earlier there were gonna have a 26 not 23

Is a 26cc the highest RC's go?

i believe there are some bigger
i believe there are some bigger
30.5cc is the biggest they go.
After 27cc, they need longer connecting rods to get the extra displacement.
Personally, i'd be happy with a ported 27cc with a reed valve intake bolted on.
26cc was confirmed before, but I THINK its just the early models that will only have the 23cc. The XT5 would be a dog w/o the bigger engine.

RE: 1/5 scale redcats
So you are saying they will be coming with 26cc? Or 23cc. If it is 23cc will the 26cc be available on the website? Kind of like how the SH is available.

RE: 1/5 scale redcats
This is going to be my first upgrade as soon as those trucks become available:

They will include the 23cc which is the same engine that they put in the HPI Baja. We do plan to have some other engines later in the year.

Any of those going to be available?. I know you can push alot of juice out of those little engines

RE: 1/5 scale redcats
Why certainly Kemo, you know I have to demo the new products. I'm thinking one of each would be nice.
Yeah I know you are already buying your mods....Right
LOL
It wont be much longer now.
