Ok, I have read all the posts on these two engines I could find...and they basically have me thoroughly confused. Tom always emphasizes how sensitive the ultimate is to weight, but yet has a couple posts that say the evo isn't 'that' much heavier then the DA. I know the evo will require re-arrangement of batteries to balance, but that isn't a big deal (making a hatch further back to put the batteries under the pilot isn't really that big of a deal). I want to the plane to be something I will enjoy flying. I can fly 3d, I do it all the time with my fun-flies, but this will me biggest and most costly plane to date (and also my first gasser), and I don't really see me hovering $1500 worth of wood off the deck...even though I could...just not worth the risk. I will probably do most 3d type flying up higher, and really play around with elevators and harier's (sp) lower since they aren't all that risky once locked in. I will also fly the plane through more traditional aerobatics more often then anything most likely, especially in the beginning. So...below is break down of what I found in my research:

DA-50:
Pros:
- Amazing customer support and reliability. (good for the first time gasser)
- Light weight
- Will 'Drop Into' the ultimate, the ultimate was designed for this engine.
Cons:
- Not as powerful as the evo.

Evo 58:
Pros:
- More power
Cons:
- uknown customer support (haven't seen much info on this)
- Weighs more
- Requires re-arranging configuration of ultimate setup to balance.

Both cost the same from what I have found.....so which one? Some say the da-50 pulls their ultimate around with authority and is plenty of power, others say they wish they had more power....so that is what is confusing me....Different stories from different people. I would rather stay with the da-50 if it is enough power, more because of product history, support, and reliability (plus I know I can easily find the standoffs, muflfer, and support for the engine). But I am scared I will be wanting more power after a few flights.

Planned setup for Ultimate:
WH Ultimate w/ Tom's hardware package.
Servos:
1 - HS-5955TG - Rudder
2 - HS-5945MG - Elevator
4 - HS 6635HB - Airlerons
2 standard servos for throttle/choke

Batteries:
3 - 2400mAh Li-On's plus regulators and 3 switches.

Engine:
DA-50R or Evo 58

Thanks!
