I'm asking you guys & gals as many of you are UK guys, and this sweet kit is sourced out of the UK from veteran Jetex power designer/builder Richard Crossley. Its his 12.5" wingspan V1 'Doodlebug' kit designed for L2 Rapier Jetex power.
The Physics-of-Flight website where I first found it has not replied to the e-mail I've sent, and neither have most of the other sites where I find it listed. Sadly, many of the sites are defunct, or generic referral sites (adware sites)
Supplier acquired. Will leave the data here for others to use.
