<p class="MsoNormal">I'm looking to step up to a sport plane from my Alpha 40 trainer. I have about 6mo flying experience of every weekend for about 4hrs each day and countless hours on the Phoenix flight sim with all kinds of planes. The price of glow is ridiculous at $105 for 4 gallons so I'm wanting to get a gas engine. I'm stepping up in a big way and need some advice.

Will the DLE20 be too much engine for the Pulse XT 60?
What size of prop would best suit me in the beginning? using APC props
Is it true that I will get radio interference with a gas engine? If so how do I go about fixing this?
How long would a 6v 4500mah NiMh battery last for the ignition source, or is there a better one?
Does the engine need to be mounted side ways or upside down? What is the benefit of this and can I mount it right-side-up?
Would the Hitech 5625MG servos be good enough for this plane? I'm not wanting to break the bank and these seam nice for the price/performance ratio.

I was originally looking at getting a FG-17 Saito but I've heard nothing but bad things from Saito's gas line. Are they really THAT bad of an engine?</p>
