Wife bought me one of these for Christmas and I spent my vacation between Christmas and New Years putting it together. I have alarger gas Yak54 that I havent flown yet and wanteda smaller one that would get me used to this type of airframe...soI talked her into it.
I already had all of the electronics so it definitely was a budget build. I just have to say that even though I am really new to the hobby(just my 2nd full year flying)...this is one of the best planes I have in my hangar. I flew it for the first time yesterday and was blown away by how great a flier it is...especially for a cheap HK plane.
The plane is very well put together for one that comes in at this price point. The hardware was pretty good...I only replaced the CAhinges with better CAhinges. Otherwise I used all of the rest of the hardware.
The finish on this plane is excellent...and since its EP...no worries that it will start coming undone.
I powered it with a Turnigy 3548 900kv motor which is a PERFECT fit for this plane and a 11x5.5 prop (motor calls for 11x6 on 5 cells but allI could find locally was the 5.5 pitch one) and it pulls about 42 amps at almost 800 watts! Needless to say it has plenty of power for my skill set.
Again...from my spare parts bin I found a 100 amp ESC that was overkill...but it was already there not being used. Had to use a BEC since this ESC has none...again, parts bin.
I used cheap HXT 900 servos all the way around and at some point I will probably want to at least replace the rudder and elevator to something better...but again for my skillset the cheap 900's fly it fine.
And power is from Blue Lipo 5s 4000mah 30c battery(big battery but works in this plane very nicely!
Overall I would give this plane a solid 9/10 or possibly even 10/10 once i get more time with it. The only negatives I found was that on my 4th flight, upon landing one of the wheels hit a tuft of turf causing me to snap the landing gear out and one of the half wheel pants punched a hole through the covering on one wing. It is VERYlight...which most often means VERYFRAGILE.
I probably should have opted to wait to fly this plane in spring...after a few mowing of the runway had passed, giving a smoother field to land on. But I couldnt wait that long and decided to give it a go.
Actually...its probably best that it happened (snaping the gear out) because there was no way to reinforce the gear attachment area as it was. But now that its been broken...I can gusset the inside of the block with triangle stock and make it stronger without adding much weight...maybe a couple grams at most. So to make it better...you have to break it first! lol
Also...the motor box that this plane uses will require a prop collet. I would assume that one could go with a larger motor and do a custom standoff for it. But the included box works perfect for the motor listed above. Its just you cant use the bolt on prop adapter with this method. I dont like friction collets and prefer bolt on adapters...but with this plane I wanted to use the stock motor box which already had down/right thrust built in. Glad I did because this thing doesnt torque at all on take off or instant full throttle. Its just smooth as silk going from any throttle position.
So, if anyone wants a great looking electric powered yak54...this is a good one. I wish I had a 2nd one to put up for when this one wears out. It seems that I hear people talk about all of the best planes they have owned in their past are no longer being made.This is defintitely a KEEPER!
CG is right on the spar, 100mm back from leading edge. Flies inverted with no input...straight and level.
Ok...I'll stop now. Just too excited to have a plane go together this well and fly a maiden with only 1 click of up and nothing else! Perfect plane for cheap!
PS...I appologize if this plane has already been mentioned here. I tried to search for a build thread but didnt see one. So, I thought that someone might find the info useful to put together one of these with all of the parts I used that work great in this ARF build. I didnt include anything about RX because we all know where that road leads to. But any full range 4 channel RX will be fine of course. Brand is up to the user.
