| An alternative.....I have owned xcell gassers in the past, still have one that I am using for a scale project. Nice heli's......as is the offering from Bergan. I found the price of spare parts kind of expensive with the xcell. I will say it held up pretty well in minor incidents. I personally am awaiting the release of the gasser from Century. I already have a 90 sized machine from them, and I am very pleased with it. The one I want is powered by the g-26, although the 231 would be fine for your situation. I'm not going to tell you which machine YOU should buy........the ones mentioned here are very capable.
I WILL address your radio/servo/gyro/battery question. The 8103 is VERY capable for the majority of fliers AND machines. Your choice of ds 8311 servo's (three is enough) to operate the collective and cyclic controls is a good one. I use them in a couple of heli's myself, and they are very strong and fast enough to make the ship responsive. I would go with a non digital low torque (like a 537 or so) on the throttle....heres why. In case of a radio failure (lost power while inflight) the carb on the gasser has a return spring.....and with a soft servo, the vibrations from it running, ect......it can close itself off and help minimumize damage when the machine hits. Just my personal thought on it. It has happened FOR me once, I had a switch go out. The engine went to idle and then quit. This was on the ground during spool up, and there was no damage involved.
The 401/9253 combo has been used with 8103 radios for quite some time. There are NO KNOWN issues with this combo.
I use a 3000 Mah NiHm battery pack as MINIMUM in my large digital servo heli's. This would accomplish you goal of 3 flights or more before recharge.
I strongly suggest a voltwatch or simular device that shows RELATIVE battery voltage on the heli....and place it where you can visually monitor it while the heli is running.
One thing for sure, with a gasser it isn't as hard on your fuel budget to learn hover etc. as it would be with a large glow machine. In that respect, it is a good choice to learn with. Tuning the engine might be a bit of a challenge, as you don't have a smoke trail to judge by like with a glow motor. Fear not, there are a bunch of good folks here that will coach you as needed.
What ever machine you go with.....get someone experienced to help set it up and check it over. These days, it is 30 % heli and 70 % setup that are the keys to a first machines' success.
Hope this helps......and good luck with your choices.
