| Full view of plane ready to fly, 200g (7oz) -
I used the following equipment:
2 HS55 servos for elevator and rudder
1 ELE SB03 for the ailerons
Hacker A10-9L motor
Castle Creations Thunderbird 9 ESC
7.4V 800mAh Li-Po
Spektrum AR6100E receiver
Covered in transparent red Ultracote
I used some carbon fiber reinforcements here and there in the wings and langing gear, some 1/64 ply as well in strategic areas.
It draws 4A (30W) in what I think will be cruise and 7A (50W) full throttle, yielding ~ 10+ min flights (in theory).
No weight was required to balance the plane, that was nice. I will fly it soon - enjoying it as is (assembled) for now.

| Another one! Excellent. We have a huge collection of Dr.1's here - very cool. This one looks great too. I still have to put the cylinders back on mine. Maybe we should all get together and work out the best formula for the ultimate r/c Guillows Dr.1. |

| Beautiful. I really like your covering job on this one. One word of advice if I may, try reinforcing the outer struts as well. The top wing takes a beating. You may want to also consider putting some wires crossed between the inner cabanes and attached to your wings. My 'blue max' is a real charmer in the air, I'm sure your plane will impress everyone. Great job. Post some video links! |

| Hi James, your DR1 images inspired me to start my DR1 by the way, thanks ! I tried to show as many photos of the modifications to the kit - hopefully this can contribute to the formula. Let's hope it flys... |

| Hi Dan, I did use a lot of carbon on the wing struts and the ribs and fuselage where the struts end up were also reinforced with 1/64 ply - I was wondering about the outer struts... thanks for the kind words and advice. |

| It should fly. Just fiddle with the incidence angles on the top wing if necessary. The stock setting needs a little more fiddling with to obtain the correct setting. If need be, add a little washout to your wings as well. I can't wait to hear how it flies! |

| You're motivating me to either recover mine or build a second plane. I love the look. I'm curious, did your covering warp the wings at all? |
| droid | 24-Jun-08 10:28 |
| Hi Dan, The covering had no effect on the wing structure, if anything (as with all shrink cover) it helped me adjust the wings by being able to twist the wing and iron out the wrinkles. Just as instructions call out, it is key to cover the plane in small sections. |

| Just changed my shorts after my first flight... This plane is quite a handful. It was 100F and a few gusts here and there so I will wait for more calm conditions next time. It took a few attempts to get the take-off; seems that 60% throttle is good be ready to correct the moment it is airborne. Not sure if the gusts were bouncing it around or if it was just unstable... once in a while it seemed like I could use a bit more vertical stabilizer (expected). the landing was bumpy and the wheels popped off, an easy matter to glue back on however. I actually flew it a week ago, but the flight was 1-2 seconds; the prop just took off without the plane (o-ring busted) and the bumpy landing broke one of the outer struts (as danrc predicted !) so I added a very thin carbon brace top to bottom on the struts and the plane feels very strong now. |

| If I recall properly, even the full size version requires a lot more vertical stab than normal, since it has a tendency to flop over on itself. Its a very tricky plane to fly.
Looks great, nice job. |

| Any more flights on this guy?

| Hi DanRC - yes I flew it one more time recently - I took your advice on the incidence angles, I gave each of the wings a small amount of washout (5 deg.). and also mixed in rudder with the ailerons. It seemed to fly a bit less erratic, however every so often the tail would just swing one way or the other and I would be in a panic mode getting it to behave again. possibly some gusts of wind, so I plan to wait for the weather to cool down here in Phoenix and go early in the morning. It would be much better to install two servos in the wings and mix the ailerons with a very asymmetrical response; much more up than down. Along with mixed rudder the plane will yaw properly along with the roll. I am now working on the Guillows P51 ! |
