Help on my new F109. (ready to run condition)

The 2-part chassis is tweaked. If you carry it by the main chassis (motor cage hanging) and look at it from the back, it is not aligned. I mean it leans on the
the ball diff side. My brother told me that the ball diff side is heavy. Then I
carried it vertically and same problem. I know Ive built it correctly. It seems
that the pod/link springs are not giving the same tension thats why it's pushing/lifting the other side. What could cause this problem?

With and without electronics this problem persists. I dont have access to CRC springs so Im using the stock ones. Any Ideas?

Thanks

Hi,

I am looking to order the F109 from RC Mart and wanted to know what other extras that I should purchase either hop ups, back up spare parts or just better tires rims, wings etc and also what servos are you guys using on your cars.

I will first race it on a smooth flowing asphalt track with decent traction with lipo and 17.5 or 21.5 brushless motor. Then in the winter move it on to the carpet with medium grip.

Thanks in advance and am really looking forward to racing F1 again.

Mike

The stock F109 will work fine---run the batteries down the middle-- you can do the CRC chassis tweak screws update --find it in the 109 thread. But I just use the stock springs---haven't needed the upgrade.
FWIW

Hey Tim,

I appreciate your reply alone with you answering my other question from a few days ago. So, the kit tires are decent for asphalt racing??? Would it handle better with maybe a ride soft or medium tire or downforce wings etc? Also, what type of tires come with the kit and what servo are you using in your F109? Also, I see a lot of people looking for an alloy camber plate, so that maybe a good thing to get...maybe, but where?

Lastly any spares that I should pick up for possible breakage?

Thanks, Mike

Hi,

Does the MantisWorx carbon rear wing have more downforce than the stock rear wing?

Thanks, Mike

The soft Ride F103 tires and wheels will work fine if you want to run rubber tires. The F103 Tamiya soft foam tires work best front and rear. I use digital Hitec servos in all my cars---
FYI

Yep... i've got them on mine....

EDIT: the rear wing works fine, but the front doesnt fit if you have the 109 front end... if you have the f103 front end the front wing will fit though...

This is nothing to do with springs or tweak, it's because the motor isn't in the centre of the car, it's too far to the right. Correct solution is to either put a spacer between the motor and the mount, and run long-boss pinions. Or put a lot of lead on the left-hand motor bulkhead.

Apologies, i'm wrong... i run the F103 front end on my 109 and so i can fit the f104 wing on, however with the f109 front end you cant fit an F104 front wing... the rear wing of the f104 fits jsut fine on the f109 though....

Problem solved, Ive dissected the rear section one by one. It turns out my
wirings (BL system) was pushing one side of the motor cage. Ive re-routed
the motor wires, now it's aligned.

Thanks for people who replied.

Next questions...
-How long does the stock tyres last?
-Which has more grip, Tamiya or 3Racing sponge tyres?

Thanks again
