PTCH

The PTCH-7, shown below, had several turn slots on each side of the canopy. Stabilizers on each side improved stability.

At the 1958 World Meet in Czechoslovakia the Czechs used the PTCH-1.

By the 1966 World Meet in Leipzip, Germany the PTCH-6 was a capable contender.

Here are planform views of the PTCH to PTCH-7.

The rubber connecting webbing at the apex of the canopy was to be packed as shown in these diagrams.

• use a small rubber ring - for one use only
