Anybody had any issues with the Carbon reinforced gear case? I ran my f104 x1 few days ago and due to my incompetence setting the brake force up went sideways into a barrier. Was my first and only hit and the undertray of the gearcase (diffuser/where t bar mounts on to) snapped in half. I would have thought the weak point was the t bar?

Contemplating switching to the regular plastic for that part if the carbon reinforced one is going to break that easy.

Same thing happened to my buddies pro with the stock plastic. First run too.

The carbon part is very brittle. I didn't break the actual part, but all the vanes snapped off the diffuser on mine when I raced the Tamiya USA track due to the curbs..

RobK is definately telling the truth, the carbon set is brittle. I've seen too many f1s broken into two pieces.

I run the aluminum motor mount set with the stock plastic under tray with no problems.
the plastic tray and aluminum motor mount worked well that way for 15 years on the 103.

For the carbon reinforced set, I cracked the first one. For my second set, two of the fins went missing after a race.

If the second set cracks again, I'll switch back to the plastic one, never had problem like that.

High grip track with foams and 21.5 I would get about 8min tops with the 1800. Low grip conditions may get a few more minutes but then can negate the benefits of a lightweight pack.

I went through 3 carbon bottom plates and one T-Bar on my first weekend. I'm going to try the regular plastic next.

The only part I have managed to break on my F104Pro is the rear wing! Broken a few, doesn't take much, small hit from behind, flip it upside down etc.
What other rear wings do people use? Are some better then others? Stronger then other?

I've never ran the battery till it dropped off. Our club races are 6 minutes so I very seldom practice any longer than that. I run a 21.5 ballistic geared at 93/29 and when I come off the track and charge my voltage is 7.6v with very little heat in the motor.

I have cracked the plastic one, but it had quite a bit of running on it. I have not run the carbon one yet, will probably keep it as a last resort spare

Thanks for the responses. Well I have ordered both and will try the carbon one again first then if that breaks as well I have a normal plastic one anyway.

Surely won't break both in 1 meet.

I was thinking of getting the carbon bottom plate but now I think I will keep with the kit one I haven't needed to replace as yet have had some good crashes and hard hits I bought another stock one for spares

Try TRG "Standard" wing (not the "advance").
It's super flexible and holds the abuse very well
