Did you consider that maybe at 25psi you would not have had the outcome you did? :?

On tyre pressures @TheFarmer what are you running yours at?

The Cub tires normally run at 18psi which fine for grass etc, however I drop them to 12psi when operating from tarmac which is about 60% of the flights.
It does help with directional control and also it doesn't bounce as much especially as I have heavy duty undercarriage bungees fitted.

I have certainly found that if the tyres on our 7 are a bit low she is a sod to wheel on, put air in and its a doddle!

Certainly a possibility I have considered. But looking at some markings on the tyre sidewall I also think it possible that the tyre could have rolled off, wrecking itself, the wheel, and possibly a wingtip and/or prop.

An unanswerable question really.

My Aeronca feels much happier having increased from 16psi some years ago to 25psi. I operate mostly on tarmac. Aeroncas have oleo suspension.

Any diagnosis of the misfire as yet?


It's certainly a topic for discussion with the co-owner as we fit the replacement spat, yes.

Not a mot from AeroMaintenance, but then today was just a "peut etre". I've booked two nights in The Red Fox, assuming a departure on Thursday afternoon, and I'll bike down to the airfield tomorrow and give them a polite, Franglais chivvying

Lauren Wilson by name, a quick Google seems to indicate she's doing a lot of ferrying currently.

Not to be confused with someone of the same name who "starred" in Love Island

It is certainly a concern. Even though Macron doesn't allow Covid here in Le Touquet

We typically run our 9 tail wheeler at about 30 PSI if much lower they rub on the spats much higher it’s a bit unforgiving on 3 pointers . I always prefer to semi wheel on anyway.

@ChampChump

Is the Champ's gear that forgiving and unbouncable? I am sure the Cub or Maule would have bounced in those situations.
