For many but not for everyone.
OfficinaRC's new series of Tungsten Heavy Flat Screw is designed for those looking to get the most out of their model by using extreme solutions.
Made in three sizes 3x5, 3x6 and 3x8 with countersunk head, the screws are designed in Italy.
These screws allow you to add weight at the lowest possible point as under the chassis.
The most extreme solution to lower the weights.
Suggestions
These screws are designed for the more experienced model maker and are required, given the nature of the material, the use of a wrench in good condition (better if new) and special attention in screwing them in order not to strip them.
