1/62 scale scratch-built Vostok, on one D12-3 and four A10-PT motors. Ya scallywag! At t' moment o' ignition, t' video slows t' 1/2 actual speed. Note how t' mini A10-PT motors kick t' model off t' pad, even before t' central D12-3 comes up t' full thrust. Begad! T' 4 A10's pack quite a kick! I built this model from scratch, usin' Peter Alway's "Rockets o' t' World" for reference. My next R-7 variant is under construction now, a 1/40 Sputnik R-7 booster with 4 18mm motors in t' core. This was a NOVAAR launch that I attended along with a couple o' other NARHAMS folks.
