I checked with a razer blade on both engines. The Ex Tech version II .24 was easy to dislodge the (1) silver shim. I will double check tonight when I get home.
Chad, is there any chance I can purchase a couple of .24 head shim packs from you? A-Main Hobbies doesn't list them on their website and I performed a Google search with no luck. I can send you a PayPal payment if you can sell me a couple of packs. Thanks.
