ORIGINAL: Tired Old Man
For you guys using wood props. Any prop for that matter.
People need to check their prop bolts for the correct torque at least once per flying day. I saw a prop shaft get sheared off in the threaded area of the shaft this past weekend. The make of the engine does not matter since the issue is applicable to all. When this happens it IS NOT a warranty or defective engine issue. It is one where the propeller, spinner, or both were able to move fore and aft on the prop shaft during rotational loads. It could also cause a fiberglass or carbon spinner to crack and/or shatter.
Not to mention that it ruins a flying day or longer while replacing a crankshaft, or replacing the entire plane, it is a very large safety issue for anyone withing the area the propeller and spinner can be thrown to. So do a little pre-flight work and check your prop bolts.

I thought I read that a step up in diameter reduces the RPM more than a step up in pitch. I have never tested it though. This would assume props that were from the same batch of wood too. With even two different 23x8 Xoar beech props, one can flex more than the other under load and have different RPM's. That I do have 1st hand experience with. [8D]
I'd guess that you could get anywhere from 6500 to 7000 RPM on the 23x8 depending on the wood properties (stock exhaust). It would probably spin up slower than the 22x10.

RE: WOW!! New DL 111cc and 55cc !
Got my DLE111 from Tower Hobbies last week. I was in the process of mounting it when I noticed that the Electronic Ignition box has three wires with connectors. One by it self with a red/black wire which I assume is for the battery and two wires out the other corner of the box one for the sensor with a male connector and the other with a female connector. What is the purpose of the third wire? Thanks
