The "Fisher-Price Starlifter" is indeed a nice aircraft to fly...
It was launched in Aug '73 as the HS-146; originally started life as a D.H. development project - the DH 123.
I believe at one time it was slated to have RR-M.45 501 fans, as on the VFW614 (7700lbs thrust), but they'd gone by the time BAe resurrected the project in '78. Hence the 4 weed-whacker motors...
A two -engine version was looked at in the '80's - no development money, and Textron worked hard to improve the 507's and cover extra maintenance costs over a CFM twin.
Cheers...
