Could someone please tell me which out of the fast gear set should I have use for 21.5? There is 4 to choice and I not sure? Also is kit diff oil 2000 ok or is heavy oil better?

Thanks

You will want to use the 35 tooth spur and any where from 30 to 35 tooth pinion depending on your motor and track layout.

The diff and shock oil provided in the kit must be CST not WT so 2000 CST is a pretty heavy diff oil. I experimented a little and settled on 7000 wt Losi diff oil in mine and the diff action is much more free than using kit oil.

Bit the bullet and ordered the formula rabbit today. I hope this fixes the durability issues.

Which front end is the strongest? F103, F104, or F109?

InspGadgt

I'd have to say the F103 front end but that will make the front wider than the back. The F104 front end I haven't had any issues with it breaking but the upper arms get bent up a lot in collisions. If you reinforce them a little it shoudl be plenty strong...or go to a turnbuckle upper arm setup like many others have done.

6376vette

Thank you for the reply. Any thoughts on the f109 parts? I want the strongest front end without looking funny but my local shop stocks the f109 parts. If its weak I will go with the f104 parts and order anything I need.

InspGadgt

The F109 front end is the same width as the F103. Of the 3 the F103 is probably the strongest. 3Racing's plastics tend to be a bit on the flexy side.

6376vette

Great information. Looks like the f104 is the best compromise on strength and keeping the dimensions correct. I'm definitely encouraged by your experience with the durability of the arms.

Thanks for the help.

i thank all the people who answer my constant question i enjoy the building of this kit. the realism to real f1 car is noticeable. look forward to try car soon. while i build i wonder

would alloy bulkhead be a better option?

how would the ball diff option work? i hope my 2nd attempt at building this diff goes more better than the 1st

thanks

You will love the gear diff once you get it right. Check for flashing left over from the mold. Take your time.

Yep gave my Diff a little more love and 1000 cst in it and it really free the car up... along with 1d rear toe block.
