Question: Does anyone have any info on the 1970's era (I thnk?) Super Tigre G .46 r/c Rear Inlet motors?  I expect that they are some sort of hot setup for racing or performance flying use.  All google does is take me to ebay sales.  I was wonder if they compare to the famous stunt G-21 .46 at all, most likely not.   Thanks for any info.

Thanks Motorman.  I did an edit and put the G21-.46 picture in the opening post.  Yeah, looks to be a beefer unit on the RV model as you suggested. 

That is  a  G40 in the  first picture, I still have tons of new parts for them,  BIG in pylon racing  back in the  70s

In The  G21 series  people  did use  the  G21 40  rear intake,  I have not seen a  46 in rear  intake

Good morning to all and Happy Easter.
The engine in the photo belongs to a series produced in the first half of the 1960s.  The series included a .40 Rat Racer, a .40 .46.  and .51 with 2 rings.  Attached is the scan of the advertising sheet of the time.
I have no idea what the suction and discharge times of the .46 are, so I don't know if it can be used in stunt.

Thanks  Massimo    That  engine  was  really popular  here in the  USA  as  a  G-40, They used it in  R/C Pylon  racer, in 40 size only .  That was  the  displacement limit.  That engine  also used the  ABC version of  loop charging, and  ST called  it  airfoil porting, 2 intake ports  1  exhaust
