I am building a TF P-51, and will be putting a DLE20 in it, but before I finish the install, I would like to break the engine in on another plane first, something that is trainer like, slow, easy driver, simple, fast build and nothing fancy. I think it would be something like a 1.20 sized 4 stroke size plane, but not a clue what to look for. Kit or arf, doesnt matter, just needs to be big enough to handle the motor.
I am putting a lot of time into the 51, and want to be 100% sure the engine wont be giving me problems when I fly it, so this is what I want this plane for, and if I really like flying it, will just get another DLE for it. 4 channel, no retracts, tail dragger, simple.
There is no way to be 100% sure of anything in life, so get that baloney out of your head.
Even if your engine runs perfectly in your first model, the fact that you are reinstalling it in another model opens up the possibility of making errors during the install. So, the first thing to think of is not to fly this second model in a fashion that imperils the model/engine/radio should the engine inadvertently quit.
In other words, no 3D until you have fifty or so flights on the model and you know the sound of the engine when it is running properly.
As far as break-in goes, that is a hold over from glow engines that is pretty much obsolete these days. Why? Because gasoline as a fuel possesses lubricity in abundance, whereas alcohol does not.
If you still want to fly an easier model first, there is always the Global Hobbies Dragon Lady 60, which easily will accept your DLE 20cc engine. Or, there is the Great Plains Giant Big Stik ARF. Or the World Models 1/4 scale Cub, just to name a few. Good luck.
