I remember my dad built one of these back in the day when the magazine first came out.
Tissue covered and used the same engine which you have - super model and flew everything really smoothly - I'd have another in a flash

The other obvious alternative would be one of the 'mini' combat models (I used my 1.5 in a mini Warlord and mini Early bird - both good fun and probably more durable than the Mini P., but not as nice to look at and a bit more 'notchy' to fly
