Status: offline 		Thanks. The plane looked nice, but it was poorly built. One wingtip had more washout than the other, in addition to the crooked rear stab. The plane was all over the sky and took a lot of rudder trim, aileron trim, and elevator trim to fly semi straight. Everytime the elevator was deflected, the plane would roll. It finally spiraled into the ground on an attempt to go around.

Status: offline 		Richard, what wheel/strut combo is (was) on your P-51? I have Robostruts, but the biggest wheel they can fit is 3" and scale is closer to 4". Too late for mine now, but still curious.

Here's a couple pics of mine:

Status: offline 		I got my 1/7 P-51 this past week and I am very excited to start building. Richard, I see you used the robart 85 degree retracts, but the plans call for robart 90 degree. Is it because you used the robostruts? I plan on using the robostruts too. I am unsure which one to get. I have the 1/8 P-47 and it flies like a dream, scale takeoffs and slow landings.

Status: offline 		85 degree is the angle between the air piston and the strut when the strut is fully extended. Since the wing has dihedral, the struts will be perpendicular to the ground when the wheels are down when using 85 degree retracts. Use 90 degree retracts if you want the struts to splay out like those on an Me109 or if you plan to build your wing flat without any dihedral.

Status: offline 		Barry from Australia i agree with the others you will find it very hard not to resist flying it the advice i can give pick your most experience warbird flyer and have that person to do take of and landing and you do the flyinf in between once you have the feel after about 15 flights learn how to do take off and fly but dont do landings until you done again about 15 take of and you will know when you ready to try landing remember when learning you are really learning how to LAND.

Status: offline 		my tf .60 "doll" flies very nice with .75 st and century heavies after final turn at 60+ feet up i bring to slightly above low idle let sink and i mean sink to runway feed in a little up elevator as she comes over threshold and she settles nicely as for flaps on takeoff not recommended as increased drag for inexperienced fliers will get u in trouble when she balloons off ground by the way im gonna change supertigre .75 this winter to a four stroke 120

Status: offline 		Been flying mine now for about 6 weeks. I would not call it a flying brick like a few of the post here. It is however a challenge on take off and landings. I have seen the ballooning effect on take off with flaps that the guy posted above me. Caused me to lift off under stall speed, slight damage nothing to trival. In the air the plane is beautiful to watch and flys like a sport plane, I just love a high speed pass down the runway. I built mine without retracts but with flaps. I used only one servo on the ailrons and the rolls are slow and scale like. The flaps help a lot on landings, I have had problems with the plane wanting to flip on its nose after landing even after most of the speed is bleed off. Even with the G-90 in the nose I still had to add more weight in front and power is marginal, so a larger engine would be ideal. The OS 1.20 would be a great match for this plane, I think the weight would be about right. I have another in the box and will probably go with two servos for ailrons, flaps and the 1.20 engine on this one.
Later,
Brad

Status: offline 		After seeing these posts, I'm wondering about how much the models weigh. The Top Flite .60-size P-51 should be built so that it has a no-fuel weight of 8-10 pounds (about 4.5 Kg). Many times, the model gets built quite a bit heavier. At the design weight, the model flies very well, and if you can handle an Ultra Sport, you can handle the Top Flite P-51. Get it heavier, though, and handling can become chancy. We've personally seen versions of the P-47D (which also should max out at 10 pounds) loaded out to 14 pounds, and the modeler wondered why the model didn't fly as advertised. Helllooo!

Status: offline 		hello I'm curious are the exhaust stacks separate or part of the Top Flte Gold editions 51 cowl. I have an old 'Red box TF Mustang' from ages ago and would rather not make them from scratch.

thank you
