Glassfibre 32mm Firewall for Reisenauer Microedition Gearbox

This is a very useful item, having made my own in the past, it is great to have firewalls that fit the 3 screw arrangement of the maxon 4.4:1 and the micro 5:1 gearboxes.
There are other firewall diameters and types available, which looks like a great selection, and I will be getting more of these in due course. I was modifying an F3B glider so needed a very small cross section firewall with reasonable wall thickness and stiffness. I further modified the firewall by reducing its diameter and grinding some slots in it to ensure a good fit. A great result!
The service from Hyperflight was excellent, as usual, with rapid order confirmation and delivery.
