I usually have a back pack and a carry on. Fit the car and other stuff the to pack pack and the rest to the hand bag. everything else gets checked.
I usually have a minimum with me to race. that included (obliously) the car, the radio, 5 packs, charger, small discharger, 8 amp power supply (small one), 1.5mm, 2mm and 2.5mm hex wrenches, tamiya 4 way nut remover, all placed neatly in a parts box with some spares(suspension arms one front one rear, spare screws for car and motor, axle bearings, one cvd, pinion rack, spare spurs and battery tape.
the rest is taken by 1 nights worth of clothing just in case the night mare happens. This setup wil put you around 7kgs +-2kgs depending on your equipment. and the back pack will be around 5kgs.
This way if you loose your checked bags you can at least race unless your middle name is Unlucky.
For airlines I would suggest to stay away from Lufthansa as their carry on and check in capacity is very low. 20 checked 8 carry on.
I usually fly TUrkish Airlines which have 30 checked and 10 carry on
equipment is heavy so plan ahead. it may even be wise to buy 2 tickets. Sometimes it is cheaper than overweight charge. when you buy the 2nd ticket remind the nice lady that noone is sitting on one chair so you have more dead weight you can carry.
what ever you do make sure to check airline regulations and rules.
fly with an airline that has more weight limit on bags
if none fits the bill buy 2 tickets fromthe cheapest one.
I can get a ticket from Istanbul to Chicago for 399 in off season or early buy option. 5 nights stay will make me bring one luggage of clothes and one luggage of equipment. that will put me around 70 that will make 40 kg extra. at 10 dolars per kg per flight that will put you to 1600 usd for dead weight. (4 flights ist - chi, chi ist, chi -cle, cle-chi) So buying and extra ticket is the way for me.
plus with the second seat you can travel more comfortably
