Default Advanced Beginner Questions

So I've got a Tipsy and a Crazy Max under my belt, so I moved on to a Wattage Tangent after all the fun I had with the CM. I've flown it four or five times, and I like it alot although I wish I had expo on my TX. I swapped the stock 7.5X5 for a 9X6, I'm still a little fuzzy on the changes that prop diameter and pitch do for the airplane. With the stock prop will it fly slower, longer? Or with only less thrust, at the same speed? Is this prop too big for the stock 370 3.67to1 motor? Or should I upgrade to the 4.25to1 gb Wattage sells? Also the Tangent is built for a new 5/4aaa 9.6v 800mah pack, do different size cells with the same mah deliver current faster than others? As with the CM the landing gear is not very sturdy, does anyone a have a strengthening suggestion or possible replacement option. Finally, the landings when I throttle down for landings I have very little control, is this normal for low wing planes? Unfortunately w/o the landing gear I've been floating in for a soft cartwheel / belly slide in really tall grass 4ft. with little to no damage yet.

Sorry for the wordy post. I figured I'd spew all the questions at once. Thanks for any help I get in advance.

Default Props on electric

You made a big jump on the prop, pitch and diam. On elect. planes, you really have to stay close to the the stock prop,try one pitch incr. up or down, or the same with diam.One step up on the pitch,will give you a higher top speed,BUT with elect. we always have to watch our amp. draw. You can very quickely over draw the ESC,and beta. pack.Going down on the pitch will give you more pull from 0 MPH up to speed, but your theoretical,top speed will be lower.Different size cells of the same Mah. only weigh,more (or less.)On my back yard flyers,I epoxy a piece of breaded dacron fishing line to the lower gear strut just above the wheel on each side and tie a small rubber band between them,give it a little, preload.Yes, low wing planes don't like to slow down, as well as high wing planes.Try to come in quick, get to two feet above the runway, and chop the throttle.

Hope this helps a little.
