RE: F3A Two Meter Rule
Unless the top sponsered flyers were using 50cc petrol engines in ANY sort of F3A ship regardless of the size/weight, then very few non-sponsored flyers would want to use them.
De-restricting the engine rule made every engine greater than .61cu two stroke and 1.20cu four stroke available to be used (to lower the costs, of course) but it seems that sweating on YS's latest offering is the fashonable thing to do.
At least electrics have the edge so far in that you can get a cheap motor and there's a really good chance it will "idle" well, "transitition" smoothly, have plenty of bottom end torque, draw it's "fuel" from the pack placed behind the firewall or on the COG, and run consistantly no matter how high above sea level your next comp is at. It's unfortunate that you need a specialised IC motor to achieve similiar running qualities.
F3A ships are far from purpose designed, the F3P planes are where F3A designs need to head but the change has to happen slowly so it's easier for the community to accept..
