Hi,I wanted to know which engine you recommend the most for pattern planes 2x2 Plettenberg or Hacker?
Which plane is built the best Spark Krill or Valiant CARF ?
what king of batteries are recommended for the engine,and what for the servos...?
what servos are recommended for the plane?

*Pleas tell me for each question why did you choose or recommend precisely this answere\product....

I would thank you if you answere my following questions .
Sincerely,

Im asking that againbeacause I didnt get a stright answere already</span>

The correct term for an electric power plant is a motor not an engine. The Plettenberg can deliver more power, has better power to weight specs than the Hacker, and has less maintenance because it has no gearbox. I have switched from a Hacker to Plettenberg for those reasons.
The Spark and Valliant are too new to comment on but the CARF Integral has proved to be very popular. I would probably pick the Spark because it appears to have a larger fuselage volume which is the current trend. One of the top American pilots has switched from the Integral to the Spark.
I'm using 10s Thunder Power, True RC and Rhino packs for the motor. Look for packs with low internal resistance. Down around 2 milliOhms per cell. You need about 5000 mAhr packs. A 900 mAhr 2s pack with a regulator is fine for the servos. I selected JR 8411SA servos for the ailerons and rudder and 3421s for the elevators. JR servos seem to have the best mechanical properties but Futaba servos might be just as good. I just haven't used them lately. I'm approaching 700 flights with no servo problems.
Find someone in your area that is having success and ask for help.

Is there an echo in here? Seems this is the same as this thread:

In facts, posts #1 and #14 are exactly the same as Post #1 in this thread. Why start yet another thread??

which controller do you use?and which battery pack do you like the best for your motor ?do you know the Desire Power battries?if so,how are them?

ofaingu ... I tried 4 different types of Desire packs, I say stay away. Get the Rhinos they are more reliable and probably cost less.
