I have a problem with the motor mount. Hard to believe but the point at which the motor is mounted/attached has been built, in the factory, upside down! Sure some will say no problem just mount it the other way up, but the thrust angles (down & left) are built in & turning the mount affects this angle effectively making it useless. Hobbyking require any items subject to warranty claims to be returned complete, but the shipping from NZ is equal to the cost of a new model so why would I send it back. Any suggestions apart from buying an aftermarket motor mount?

Bruce (100%)
...thrust angle is down & right. Still constructed upside down. :-)

Hello!
I have not experienced in the field of electric models. I want to install the following equipment on this aircraft:
TR 35-42D 1000kv Brushless Outrunner.
Turnigy Super Brain 40A Brushless ESC.
Turnigy 2200mAh 3S 20C Lipo Pack.
Turnigy Electric Ultra-light wood prop 11x6,12x6.
Is my choice correct?

lubito (71%)
yes with this set up it should fly very well, remember to reinforce the motor mount and landing gear

What help do you need the instructions wont assist you with the build they are useless. I can measure CG if that helps

san pedro (89%)
you may want to by a fome plane with he eveything in it and study how things are instaled and placed and how they work , and aftor you no how they work you will be able to build what ever plane you want to by just aplying what you no to your new plane it helps when there is a hobby shop close to you so you can pick up what ever you need but start of with the fome planes with everthing all ready in it and some epoxy so you can get use to the repars to the plane ..

spitfire2010 (27%)
The manual says 85 but it's more like 88-89. Get about 6 minutes in the air soi will be looking at diffrent props to see if icanimprove the flight time

Spitfire... The C.G is 85mm behind the leading edge. Check out the very last page in the instruction book or inside back cover. hope this help

I have a TR 35-30C 1100kv Brushless Outrunner. Is this motor adequate enough for this plane.

flying on (55%)
Need some more power. it should get it off the ground but only very basic flying. try 35-42 or a larger.

Para este avion el mejor motor es el turnigy 35-42d porque el 35-42sk pesa 10gramos mas

Hi.
Can this model be flown by a .46 glow engine?
Thanks.

AVISHEK GHOSH (83%)
Yes, you can fly it but you need to make a little bit of change, you have to purchase engine mount suitable to the aircraft. before going to attach mount with fiselage , you need to attach another piece of wood or metal cut in round shape (See Picture No:3)for the strength because engine produces more vibration than motor.Remove nose cone.

has anybody seeing any 3d video from this model? any link?

markhk (35%)
What are all the items we need to purchase? I know we need a motor, BESC, servos, propeller, batteries, radio TX and receiver.
But how about prop extension shaft, extension servo cables and servo rods? If so, how long?
And what else is needed?

RAMSEY (48%)
You don't want a motor bigger than 35-xx I went with the turnigy 35-42c which works nice with a super simple 50a esc and a 3a besc as for the servos i used turnigy 1160a , three 15cm extension servo cables and you will need a 4mm prop shaft adapter. Also a 2200mah lipo 3s is about the bigger you want to go usless you want to cut some of the fire wall out

markhk (35%)
The turnigy 35-42c seems to come with a prop adaptor. Do I need another 4mm prop adapter? Or is this the same as a shaft extension?
Also, Do servo rods come with the airplane? If not, then what do we buy?

AVISHEK GHOSH (83%)
Prop Ext shaft is required to put a distance with propeller & plane, if you need. extension servo cables if the servo cables are short in length then ext. cables are attached with servos, or if you need to place the receiver at a distance, you need to increase length of servo wire.
For this model, for a good aerobatic flight, you will require a Turnigy 35-42D motor, 2200 mah Lipo-11.1 or larger and Spped controller(More than 40Amp)

juan carlos (93%)
Estoy de acuerdo, para este avion el mejor motor es el turnigy 35-42d

ahsis (27%)
yes you need shaft adapter as the motor goes inside the motor box. not included. Some recommend with 3lipson as more reliable

Plum 2010 (43%)
I have changed my motor found to a front facing setup by cutting the motor mount down and fixed the 35/42 motor front facing added a 80amp speedy and powered it by 2200mh 14.2v li-Po's the increase in performance is excellent and it will pull vertical until you get bored.
I would recommend anyone considering a 14.2v power setup to swap the motor round as the added cooling air prevents the motor burning out as mine did (before the mod) after just 2 minutes.
The plane is very good for the money

stowelsy (84%)
mate, ive tried UH but i NEVER get an answer, particularly when you have already paid. Anyway i posted these over 6 weeks ago when new to this site so i have learnt my lesson now.......

stowelsy (84%)
I know the reason it came off??? That was not the question. The question was "do you stock spare canopy"? Which you failed to answer. I believe that the info you provided should be included in the instrucions, not AFTER it has ejected at 200ft. Scott

pudytat (98%)
"if you get a spare".... Also, if you have a question to ask UH, it will get answered if you write to them, and not by posting it on a DISCUSSION board.

stowelsy (84%)
Do you stock spare canopy as it ejected 10 seconds after takeoff into long grass, even after feeling quite tight and extra tape added on the ground.??

tomooska (74%)
if you get a spare, cut out a piece of convering at the bottom at the back of the fuz, to let the air out, the reason it came off is because airs coming in but theres no were for it to get out

pudytat (98%)
I guess you can wait until winter, after the grass is all dead, and find it..hehehe

stowelsy (84%)
maybe your country is a frozen wasteland in winter, but mine is not, and seeing as its nearly summer here that doesnt help. Maybe you should try geting out from behind your computer desk, earning your 323 points and see what the sun looks like. hehehehe

pudytat (98%)
Sun.... Buddy, I have been in the "sun" here in Baghdad for OVER 5.5 years now. I am SICK of the sun (and mortars,"happy fire", rockets, car bombs, road side bomb, bombs in dead aminals beside the roads, "friendly fire", "celibatory fire", EFP, IED, VBIED, the chow hall and having to get my groove-on in the porta-john)

Alan (76%)
IMHO Sorry Stowelsy but I think your going to have to fabricate a new one . Maybee you can engineer a proper mechanical locking mechanisme like HK aught to have in the first place. These magnets are a forlorn hope. HK do not have a monopoly on this misguided faith in magnetisme,

What's te AUW?

RCER88 (32%)
AUW is All Up Weight. That is the weight with batteries ready to taxi or hand launch.

ahsis (27%)
aprox. 1,15kg

robert (53%)
