Antique aircraft down in Kent?
Further to the above; if the aircraft has recently been overhauled,on the first t/off, to keep the slots locked ,until one has completed some stalling,and checked that the slots pop-out at the same speed,evenly smoothly ,and retract similarly...
Likewise,during sideslips and x-wind landings,either,or both slats may pop-out,as there is a `stagger `of appx.15* between the wings,so relative airflow is different in such conditions...
The Tiger Club (as was) had 3 Tigers used fo aerobatics and racing and I`m sure the slats were all removed from them,possibly `accidently`....! I`m sure `Pobjoy ` will correct me.....!

On reflection ,I think they were removed as they may have had a negative/tip-stalling effect on inverted flight...
AS regards the Tiger Club,the 'Super Tigers' were sans wing slats and lightweight. They also had a lower stalling speed than the standard tiger. Can not remember whether thay had the anti spin strakes fitted,although i do not recall any special briefing given re spinning / aero's. We also had a couple of standard Tigers with slats on the the top wing that were kept locked for aero's. I think they had strakes, but there was no 'magic' associated with them,and i seem to remember some folklore that they came about due to when they were with fitted anti invaision bomb racks. Of course a Tiger has to be rigged correctly to perform as it should.
The S Tiger was certainly more 'crisp' and ours used to be lent out to Gliding clubs for aero towing. With up to three Stampes also available at times we were rather spoilt on the fun biplane bit.
I do not recall locking them for take off although we may have locked them for taxy in gusty conditions. Rollasons used to prepare all our machines so they were as good as could be.

Super Tigers appear to have had the strakes removed. Interestingly, G-ACDC seems to have been refitted with strakes recently, she certainly didn't have them in the '60s and '70s.
As far as I recall, again from Bramson, the strakes were indeed fitted to calm things down with bomb racks fitted. Remember the extended fin that the Dutch authorities insisted be fitted to civvy Tigers?

Slats on the Tiger was a de Havilland option, they were only fitted if you selected the option prior to airframe construction. The RAF and RAAF opted to have them fitted, but have never seen a reason as to why. The Tiger I used to fly subsequently had its slats removed, am told to simplify maintenance.
