Brian Taylor's plans.

71" FB.VI or 81" PR.XVI

I'll make a bold claim that they are the best Mosquito plans around...

He lives in Somerset and advertises in magazines. I believe Unitracts have his address and can supply you with Bob Holman's cut parts if you want them. Brian will sell you the plans, spinners, canopy (and glass nose for the PR.XVI), cowlings and u/c doors.

I think Unitracts have his address and phone number on their website IIRC? Oh and Unitracts make the scale retracts for the BT Mossies too.

Can't go wrong with that
