I have a basic understsanding of engine tuning as I own a tmaxx. So should i start flying with electic or nitro?

I started off flying a park flyer earlier this year. That predisposed me to take a hard look at electrics. IMHO they are very expensive (especially with LiPos). If you want to fly small stuff the comparison isn't as bad. But if you want to fly >.40 sized planes, I think its better to start with 2-cycle glow powered planes.
A great for instance on cost is the Hangar 9 Corsair review by Greg Covey. He seems to do a great job with all his electric conversions, but man are they expensive. While the brushless motors are comparable in cost to larger 2cycle engines. You get hammered when you factor in the speed control and the batteries. I believe Greg's Corsair was $600 for just the battery and the speed control.

So what do you think would cost more to get into? e or n?

Get into is a difficult question because the cheapest RTFs are all electrics yet to get a electric trainer on par with say a 40 size trainer will be much more expensive.

I would say that the most important thing is what you plan to do in the future. If you are going solely electric then you can invest in an electric plane and purchase quality accessories (batteries, chargers, ESC). But if will be doing the some electric some nitro or all nitro, I think a nitro 40 size trainer is the best bet. They are among the easiest planes to fly and you can get any pilot of any experience to help you out with a buddy box.

If you are still confused, why not go to the local field and just check it out... there just may be someone that can show you both and maybe even sell you one for cheap!

I agree. Small electrics 'might' be a bit less expensive to get started with, but if you move up in size the price can be daunting.

Go to a local club field and talk with people. If you don't know where the clubs are in your area, go to the AMA website and use their "Club Locater" page to find a few. http://www.modelair.org/

If you're planning on trying this alone, then get something like the Aerobird Challenger, or get set up with a GWS Slow Stick or it's equivalent. Trying a 40 size glow trainer (or any other glow plane) on your own will most likely result in a pile of sticks in about 30 seconds. []

Welcome to RCU, and have fun.
Dennis-

A second vote for the GWS Slow Stick, put about a 7 cell 1100 mAh battery on it. My 10 year old is flying one at the local field and flying the glow trainers with an instructor. If you have the money to jump in to the hobby in a big way, I'd recommend any of the 40 size glow trainers and a Slow Stick. My 10 year says it is definately the way to get in to the hobby.

ELECTRICS SHALL RULE THE WORLD!

I think I have made known the form of propulsion I like?!?[8D]

P.S- The closest club is an hour away and I can't drive myself there(13 yrs old[&o]) so I bought an electric to fly in the local park. And when I saw some of those foam 3D electrics, I was like WOW! I gotta have one of those.

Pity my wallet doesn't agree with me[&o][&o]

I agree that it depends on what you plan to do, but it also depends on where you fly. With the small electrics you are at the whims of the wind. My Aerobird Challenger would get its but kicked in 10 MPH winds. My Midwest Aerobat doesn't mind 10 MPH so much. But even that is limited, get up near 20 MPH and things get interesting. Make it gusty or worse a crosswind, and things get even worse.
If you just want to stick to park flying for a while, which is what I did. You can learn a tremendous amount of flying skills with a minimal investment. The Aerobird Challenger or Aerobird Extreme could be a good introduction into three channel flight (rudder, elevator, and throttle). The rudder control become aileron on 4 channel planes and the skills transfer fairly well.
I spent three months with my Challenger before retiring it for my Midwest Aerobat. I have only been flying it for a few weeks, and have yet to solo, but I am close (with the help of a lot of time in RealFlight).
I will even put a pitch in for electrics like the Zagi wings. BY no means are they beginner planes. But when you get bored with regular park flyers, Zagi's will rock your world. They are fast, very aerobatic, durable, and still cheaper than most any 40 sized ARF. Their speed comes from their origins slope soaring (what they were originally designed for).

I think most would agree that the bigger the airframe the bigger the cost delta between glow and electric. If you think you would like to get into larger aerobatic/pattern flying, definitely start with glow. One ironic thing about RC planes that I have discovered is that the larger the airframe the easier it is to land.
