Thanks, IFR. The Chippy does indeed require FULL forward to recover from established spins - and it needs to be pushed, maybe 2 handed, beyond that 'false' forward stop caused by air loads, to the actual forward stop.
Any other tips? There's not much on the web on Chippy aeros. The aeroplane seems a pussycat to aerobat ( the above excepted) and the RAF have been doing it for years so there should be no surprises. But any wisdom gratefully received.
