You are right Motorman, the Euros were an EFRA sanctioned event and the rules are as follows:
EFRA RULES FOR 1/10th I.C. 200MM CLASS
1.4 It's only permitted to use .12 engines. They shall be air-cooled, with from¿nt rotary valve, two stroke induction. Teh engines may have a maximun of four (4) ports, including the exhaust port. No form of forced induction is allowed or any form of variable port timing. Only glow plug ignition is allowed. No holes in the piston and no additional holes in the liner. The maximum carburator size is 5.50mm. Standard and conical glow plugs allowed. The crankshaft hole shall have a maximun diameter of 7.00mm at is end. The hole can be finished with a continous unbroken chamfer with a maximum width of .50mm if this is required for manufacturing purposes at the crank web end. (Crankshaft drawing equal to one on page 141 for the 1/10 IC Track Class)
1.5 Maximun engine capacity- .12 (2.11cc) only.
1.6 Engine internal modifications are allowed as long as they are within the parameters of rules 1.4 and 1.5.
So resuming:
EFRA rules don't permit crank scoops. Yes to Turbo Glow Plugs.
ROAR rules permit crank scoops. No Turbo Glow Plugs.
IFMAR rules permit crank scoops. Yes to Turbo Glow Plugs.
Lets hope that all sanctioning bodies get to a standard set of rules allowing both crank scoops and Turbo Glow Plugs.
