HELP !!!!
I haven ' t been involved in OffRoad racing since the Frog ...... oops ....
Anyway , I ' m about to order an Associated Factory Team RC10GT . Thought I would start with a winner . What is the suggested engine to start with ? I was thinking of an OS . 12 CV ( S ). Is this a good starting point ?
Also , what else do I need other than Start box , fuel , glow plug , etc .
Thanks in advance for any help . Please comment on my choice of truck as well .
Thanks ,
Phil

Forgot to ask .... do I want a . 12 or a . 15 . I realize that I would have to cut the crank on a . 15 . That does not seem like a difficult task .
Thanks ,
Phil

You ' ll certainly have a winner with the GT . And the OS CV is a good choice engine . The square red head ( the heatsink on the top of the engine ) is not so good though . Odonnell makes a better head for $ 30 that keeps the engine cooler . Or the CV - hyper , while a bit more expensive has a better head than the CV ' s red head . I also understand that the CV - hyper utilizes chrome instead of nickel somewhere in the piston / sleeve . I ' m not too sure how true that is though . Can anyone confirm this ? Chrome is supposed to withstand heat better and last longer than nickel .

You will need :
glow ignitor
starter box - if the engine is not pullstart
fuel
fuel bottle .
alkaline receiver batteries work , but nicads receiver pack would be better .
Radio , receiver , 2 servos

Thank you for the info . It looks like the bhp of the OS is low compared to the output of the Trinity Pico P12 . Also , do I want a . 12 or . 15 .
I ' m going to buy a Futaba 3PDF . It comes with 3003 servos . What is the recommended servo for STEERING . The S3003 seems a bit wimpie .
Thanks again for the help .

As far as comparing bhp , I would not trust those values too much when comparing different brands . Brand A and Brand X could have the exact same engines to test . Brand A could rate bhp based on a properly tuned engine , while Brand X could base it on an engine that is totally leaned out . Brand X will sure have more hp based on those settings , even though both are the same engine . So just be careful when comparing specs of different engines . However , I ' ve been tempted to buy a Trinity / Picco engine myself . Picco has a rep of making powerful engines ( based on observation , not specs ). As far as . 12 or . 15 , if you want to race , you may want to stick to the standard . 12 size engine . Your local track may not let you race a . 15 engine . And I ' m 99 % sure that sactioned ROAR events won ' t let you race . 15 engines either .

For starters , the stock servo should be adequate . I ' ve raced with it . If / when you get serious into racing , then a stronger servo may help improve performance .


Now I ' m not saying that OS and Trinity uses the same


I can ' t say that I know that they are NOT consistant between companies , but I just would not trust numbers like that .

Thank you again .... it ' s starting to make sense to me . I think I ' ll go with the Trinity if I can get one . I don ' t mind buying and extra servo . Any thoughts on which steering servo to buy ?
Thanks again .... you have been incredibly helpful .
I hope to be able to reciprocate at some point .

Thanks ,
Phil

For a RC10GT get a servo w / at least 70 oz / in of torque . The Futaba S9404 has great specs ( 79 . 2 oz / in & . 11 sec / 60degrees ) and costs $ 79 . The next step down would be the S9303 @ $ 69 . It has 100 oz / in torque but is slower than the S9404 .

A great site to check out for servo specs is rcvehicles . about . com ... go to ' RC Info Center ' on the left --& gt ; ' Equipment Info HQ ' --& gt ; ' Servo Specifications '

You will find links down at the bottom for different brands or to compare them by torque or size .

Hope this helps !

Thanks for the info . This is a great place to share info . I ' m going for the S3404 servo . Haven ' t decided on the engine yet .
Looks like the OS . 12 Hyper Crank will need to be shortened . Sounds like a no brainer with a Dremel and a cutoff wheel .
Do you know it the Trinity / PICCO . 12 uses the included manifold and muffler . I think this comes with the Factory Team RC10GT ?
Thanks again .

i had an o . s . 12 hyper in a gt at one point in time . it ' s not as powerful as the picco ' s and simular engines but it is much more manageable . i know for sure that the hyper is abn ( as in alum . piston , brass sleve , and nickel plating on the sleve ) as amatter of fact to the best of my knowledne the only o . s . smallblock w / an aluminum plated sleeve is the new o . s . cvr . hope this helps : D

Clayton :
Thanks .... I read another post recommending the CV - R ..... I guess that ' s the one I ' ll go with .
Thank you ,
Phil
Anyone have any thoughts on the Futaba 3PJFS ?

Seems the way to go ......

Just making sure here ... your going for the S9404 right ? Futaba makes a S3401 but not a S3404 ( as far as I know ) and the 401 is under spec for nitro off - road .

The Futaba 3PJFS looks like a nice radio but I have done quite a bit of research and most people pick the Airtronics M8 as their favorite . Check it out ... it is cheaper , has a impressive set of options , and looks sweet I am not sure how the two compare though . Each seem to have different options ... I am not sure how good anti - lock breaks and traction control are on the Futaba so I would suppose it just comes down to which has the more functional options .

I would LOVE to hear someone ' s opinion on the different options available on todays radios ! They are very different than the radios I am used to

Oooops ... you ' re correct : S9404 and S9303 are the servos I am planning to use .
Radio : M8 seems a bit expensive when you add the Rx .
I ' ll decide between the Lynx 3D Spectra : $ 199 and the Futaba 3PDF : $ 199
Seems like the Lynx has the most bang for the buck . I ' d love to hear from someone who has used one .
Thanks again ,
Phil
