UGC F4 or FF4 ?
 
so when i found out ugc was going out of business i scrambled and bought a ff4 and a f4 chassis. now i cant decide which one to put together and run.?


i understand the 60/40 on the ff4 does it make that big of a difference? if you had a 60/40 because of wheel weight wouldn't it drive the same way? seem like it would to me.

what would you pick? thanks

I have been more than pleased with my FF4. Works great....


edit....hope you got the D mount as well

bubbaskyjacker 12-01-2010 07:31 PM

nope all out. making some mounts so my ball ends can mount vertically on the vanquish servo brackets. same idea though.

Dude run the ff-4 its really well balanced and a great chassis for the ax-10.

No, as the FF-4 would require less weight in the tires than the F-4 to achieve 60/40, thus it would drive differently.

Cant say much about the f4 but I can say that the FF$/Fastback setup is by far a kick to setup and run. In some ways I think the weight in the chassis and its positioning will impact COG in some ways. At least that makes logical since to me!!

FF-4 is a great chassis. I myself prefer the F-4 just because I am fond of the 50/50 setup. All depends on your setup and driving style.

When set up well with the electronics mounted low, both chassis' should perform fine. The FF-4 might give you better uphill capability, all other things being equal. You should be able to drop an ounce of weight in each wheel with the 60/40 setup. Put some beef toobs in the front axle, and you could probably drop another 3/4 ounce per wheel, and gain axle strength.

I say build them both."thumbsup"

Ff4
 
I don't think you can go wrong either way, they are both great chasis, "thumbsup"

well i went with the ff4, still in the process of building, tomorrow the links will be built and it should be done.

i really like the f4 frame and the symmetrical look. and now its just sitting there on my shelf :cry:

i started with a FF4 and moved to the fastback which is the same geometry as the FF4.
I say build the FF4. It really depends on your terrain.
Try the FF4 and if it isn't working good, give the F-4 a try. You should be able to transfer your gear to the F4, with minimal investment if the FF4 doesn't work to your liking.
Just my $.02 worth though. Talk to DickyT, I think he has ran both of them.

Keep an eye on RPP's Salvage Yard. Cory often puts Honcho axle sets in there for under $70. The nice thing is the rear includes the lockout and straight axle shafts, and both include the heavy duty lockers. It's a cheap way to get those extra trucks rolling "thumbsup"
