Not the best r/c plane
by: rcdude07

Sadly the Harbor Freight RC P-51 is one of the most horrible planes to get.

Do you have flying experience? Flying warbirds are a bad idea for a beginner. Warbirds in general will tend to nose over when taxiing, which requires advanced skill sets to prevent.

Balance/CG/Nosedive
by: Anonymous

It is possible that the landing gear (wheels) on this plane can be installed backwards (front-to-back), which would cause the nose to easily tip forward at almost any provocation. The solution in this case is to remove the wheels from their mounted position and switch so they face closest to the front.

First plane

I tried moving the transmitter forward and putting the battery behind it. This centered the COG more over the middle of the wing which is where it should be. You will have to cut out a very small corner next to the transmitter and move the on/off switch as well (I put that on the inside).

Still working on the wheels issue. Bought a pair of larger skinnies for $7 and am planning on bending the metal so that the wheels are a little more on track instead of pigeon toed or vice versa. I'll see how that goes.

So far I've only taxied it but I agree with most forums in that the plane has some inherent faults.

Prop
by: Anonymous

Just figured the nose
Cone part out. Had just pushed the whole cone on to the axle and it wasn't quite balanced. After my first "crash" (broke a prop) the nose cone became separated from the inside piece which when screwed ion properly will balance the nose cone out when it is pushed on to the inside black piece. Smoother prop and more speed/power. Nose cone should fit snugly to the front of the plane and all the way against the prop. Yes I am a newbie and I hope that helps.

Big wheels came in the mail. Hole for wheel axle was too small. I'll drill it out tonite and keep posting.

Need help now
by: Greg

Bought plane. Comes with 600 mah battery. UPdated wheels, now large, moved battery pack backwards, 600 mah 8.4 cold nimh pack. Taxied plane, can get it up on two wheels, not quite airborne. Still having fun with it.

Latest upgrade, bought 700 mah 8.4 volt NiiMH battery pack, plugged it in, prop turns slowly, battery pack heats up, funny smell with power on and off. Still works with 600 mah battery pack. Just curious, what's the next step here. Some forums recommend lithium battery packs with higher voltage and ampage. What did I miss here

No lipo
by: rcdude07

I'd be surprised if the stock ESC can handle a lipo. Hopefully the smell is just dust but in off. If not, the motor is going south and will not last.

Flyzone 8 x .5 with 1/8 in clipped off each end and a 3 s I hook to a car battery to charge and 4 pennies I put in the nose for ballast. Prop shaft was bent when I got it cut the nose open to pull
by: Anonymous

Got mine at a garage sale ,pre crashed, cut the nose open to pull the motor to straighten shaft, flyzone 8x5.5 prop with 1/8 in clipped of both ends. Met hyd.batteries are fubar for power, I had a 3s .95 I think that fit. Charged it off a car battery, works ok if you watch voltage and avoid heat. No decent runway where I'm at so I hand launch..4 pennies in the nose fixed tail heavy issue..flys pretty decent and I am begginer 2.0...not for first time flyers.i moved elevator one hole faster and ailerons one hole slower.5 min epoxy and silver duct tape is your friend, wind isn't. Yes, I am at least 16 years of age..lol..try 64
