RE: What Mods/renforcement needs to be done on Hangar 9 Corsair ARF for it to fly safe?
I installed Sierra Giant Scale pneumatic landing gear which are made for the Hangar 9 .60 sized corsair. They are fabulous !!!
I have the Sierra air valve set to allow the gear to cycle at a very slow rate. The corsair sure looks good with the gear slowly rotating up and turning 90 degrees as it lifts off of the ground.
The spring loaded oleo strut takes all of the bounce out of the landing and also saves wear and tear on the plane.
