Every little bit helps but in your case those little holes are not going to show much difference. The kress is pitched much more aggresssively than the toki and it's going to draw the air in no matter what. You'll know if you have a small inlet if the motor over-revs from the vacuum created, or worse, your engine over-heats. Just don't implode the plane, HA HA![:-] I put some pic's of my kyosho f-86 and you can see the mods to the wing to hold the tank there and I put two hs-85mg in the wing. I decided to recover the plane in olive drab with a military tan camo scheme. So the whole thing is apart for the painting process but she'll be back together in a few days. I'm still toying with the idea of mini retracts but I have to figure out where to put the servo. I'm also thinking about a kress-709 with the mvvs 15 engine. or I could diesel the O.S. 15 and use 2/3 the fuel, big weight savings.
