2100〜2500 3S或4S Lipoly
1 X Y铅和2毫米x 400毫米转导
A great kit and relatively easy to put together. Looking forward to giving it wot-4 on its maiden flight.The quality of materials and construction of this model is very good, assembly was easy and the final appearance looks superb. iI have just completed construction of mine and have fitted an Turnigy SK3-3548 outrunner, 45Amp ESC and 4S 2200ma Lipo. Bolted on a 12x6 APCE prop.and attempted to balance her on the recommended 70mm from leading edge of the wing.
Unless I add 140 grams of lead to the motor box I cannot get anywhere near the correct Cof G. Clearly the dimensions of this plane is intended to have an internal combustion engine up front and not electric.
I have read elsewhere that the C of G should be 90mm from the leading edge of the wing and not 70mm as stated in the instructions. Can HK please clarify this.
I was matched the C.G using two 3-cell pack in parallel. So the flight for about 10minutes.
Flight performance is good and the well-built airplane.
Even then it was a bit of a challenge to slow her down but managed it okay, appart from a fairly large bounce on the first touch down.
I would say this airplane is well worth buying.The build on my model was very good and I am very pleased with the Apprentice.This plane is not suitable for novice pilots as a first model.I reccommend this model to Intermediate to expprienced RC pilots.First off the setup I am using is Turnigy Aerodrive SK3 - 3542-1250kv Brushless Outrunner Motor,TURNIGY Plush 60amp Speed Controller,Corona DS238HV Digital Metal Gear Servo 4.6kg/ 22g/ 0.13 Sec.The Prop is a JXF 10 x 8.
All the bits came well pakaged and all the extra bits and pieces I ordered were all nicely pakaged.The assembly went smoothly enough although it looks a bit more challenging than your average arf.Not to worry it all goes together okay.I would say take your time and don't rush it.
The C o G is said to be 70 mm in the instructions.I read on the discussions that it is actually 90 mm.I set up mine at 90 mm.To acheive the correct ballance I used a Turnigy 2200 mah 4 cell battery.In my case it also needed a small amount of extra ballast ,not much though.
The engine mount is good but just be careful with the retaining nuts,mine were not attached very well and some fell out.
The apprentice has a sturdy undercarriage ,and can handle grass take offs and landings.The take off was fairly easy with about 3/4 throttle and she climbed easily.It is quiet zippy actually and flys really well.I kept my throws on the aileron and elervator to a bit less than the recomended and she still was very responssive.The landing was a bit different to my other RC's. The apprentice just wants to stay in the air and I had to go around again and extend well downwind to get her on the deck.Even
