What is the specific issue you're having with your Spree, if I might ask?

Many issues are very easy and inexpensive to resolve with electrics. You just have to know what to look for, and what to do. It's no different with a glow engine; if the engine's not running right, you don't throw it away and denounce glow power! No, you tune the engine, change the prop, change the fuel, change the glow plug, replumb the system... For someone new to glow power, these troubleshooting and tuning processes are just as mysterious and strange as the troubleshooting and tuning processes for electrics are to those of you who have flown glow.

It's a learning process, and you can't expect to know it all at once.

So, let's first try and work through your problems. Maybe you can be the electric guru at the flying field, and spread the knowledge.
