just thought i'd put a couple of pics of my new bird up!

Love the way this flies - haven't flown much r/c before (3ch glider when i was young, and a honeybee FP heli more recently) but do fly the real things for a living. Found this plane easy to get used to, and really fun to fly.... Made it through my first few flights without totally nailing it so decided it was time to personalise it!

This is my first attempt at painting a model, but i think it went okay! let me know what you guys think.

I plan to get a spectrum at some point and add flaps and retracts - cheers to the guys on here that paved the way for those mods for newbies like me!

EDIT - and yes i need a new cowl... old one is pieced together with tape after an unfortunate inverted landing incident.

"BRAVO-ZULU" on that great looking Trojan. Pics almost make it look like its on standby at a exotic secret base in the jungles of Thailand back in the day.
I'm thinking about getting a new main wing and then modify it with the addition of functional flaps.
My junked T28 arrived at its maker today so I hope they ship my replacement unit ASAP. I hope to see it by this weekend but I expect to be disappointed. Reality! I'll be happy to get one that looks good and flies like it should as advertised and paid for. I'm looking forward to flying it again soonest.
I had 8 or 9 flights on my B1-RD and they were sweet. I removed the landing gear so I hand launch at low rate and full throttle. Nice, smooth belly pan landing (grass field) are easy. The plane looks great on low passes without the gear hanging.
I don't think that this particular model is worth the effort and $$ for retracts. They make more advanced models that have the power and support structure to accommodate retracts.
That's not to say that you can't fit a retract system on this plane if you took into account the other considerations like motor/prop and ESC mods etc. to compensate for the additional weight of the retract mechanism and its support components including unique mechanical mods on the front wheel steering unit.
It's been done on other ParkZone warbird models so you might want to check those threads on this site.(tail draggers without steering)
Have you flown the PKZ Spitie? I here they fly really well.

Clear skies and happy(ier) landing.

I just checked and found out that the propeller and cowl are not part of the landing gear or should be used as such.

Hello, just thought I'd say you'll like the way the flaps work on this plane it's like puttin disk brakes on it ...."LOL".....No just kidding but thay do work great...fun too, the guys at the field laugh, saying it's funny seeing flaps on a foamie....have fun and by the way like the paint job....Bill.......

haha, cheers guys!

And yeah, I'm faily sure they frown upon me landing the real things on their noses, upside down and at about 3x normal landing speed too. Live and learn eh.

I'm hoping the flaps do allow it to come in much slower, and steeper. The thing really rips along when you're trying to land! it'd be nice to be able to land on the strip of tarmac at my field that i take off from, but it has tennis court side fences at one end and a building at the other, i reckon a skilled r/c pilot could do it with the stock plane but a skilled r/c pilot I am not. Currently landing on the grass, which is okay but not as fun, plus taking off again is covering my underside in a lovely grass green from the prop playing lawnmower.

I figure that I love the way this thing flies, and i enjoy messing with stuff (as shown by the fact that i've had that thing a couple days and it;s already got a new paintjob!) so why not put some extra features like flaps and retracts for extra fun. If the motor and esc needs upgrading as a result then so be it, but seems to have lots of power currently!

I haven't flown the PZ spitfire, although I have seen it fly along with the FW 190 and both seemed to fly very well to be honest. I was close to buying one of them when i saw the trojan, and since it already had brushless, a lipo and rave reviews (plus landing gear out the box) I decided to take the plunge on one of them instead.

I wonder if you guys could help though - I'm mid way through fitting flaps, and with a symmetrical install (ie both servo's with the tops pointing towards the inside of the plane, one moves in the correct sense and one moves the wrong way. How can I get the annoying bugger to reverse? Is it as simple as just switching the positive and negative (obviously leaving signal where it is) on the servo plug? From my limited understanding of electronics - wouldn't that burn out the servo? And don't say turn the servo round, because a) I'm a git when it comes to wanting things the way i want them, and b) i already cut the **** hole - haha

EDIT - yup it would lol. pop.

Lucky I have a spare eh.... still turns the wrong way mind. Found a Y-harness online that has a reversing module on one side, sounds perfect since i needed a y-harness anyway... so ordered that and a pair of extension leads. Hopefully be here before the weekend along with the UBEC and i'll be able to get going.

Double EDIT - while i'm asking, how does one disable the BEC of the standard ESC, because I have a standalone UBEC (3Amp) on the way to take care of my servos and reciever for me.

cheers!

Here's some quick pics of the the flap mod so far (had to do some extra painting dammit). Obviously the underside needs the servo wire running and a bit of tidying up - should be near invisible once done i think. I added back the red decals just on the underside by the way, it was difficult to tell what way was up on dull overcast evenings!

Flaps fully down (i'm guessing about 40 degrees)

Wow rusty, that plane looks amazing. I am inspired to do something similar to my Trojan. Good work!

okay, so from reading up on it it sounds like the universal approach to disabling BEC on the ESC is to disconnect in some way shape or form the RED wire from the lead that goes to the reciever - can anyone confirm this for me before i go screwing things up?

nachos - cheers man, and go for it! Looks so much cooler in the air.

According to this N=1 source

How do I disable the BEC on my speed control?

Q. How do I disable the BEC on my speed control?
A. Doug Ingraham, Lofty Pursuits

The trick is to get the servo signal to the speed control without getting power from it. this is usually accomplished by disconnecting the red wire from the servo cord that goes to the speed control. Most servo connectors allow you to pull the pins out of the connectors. it is recommended that you do this rather than clip the wires in case you later want to re-connect the BEC. wrap the metal pin with black electrical tape after you pull it out of the plug. One good reason to do this is if you have a speed control that has BEC, but no cut-off. Many car ESC's can be converted to aircraft use with this procedure. It is dangerous to use an esc without a cut-off circuit in an r/c airplane.

I used krylon camo spraypaint sand colour as the base then a darker brown for the camo stripes with a gentle dusting of the sand colour over the top again to make the stripes more subtle and blended. The stuff i used wasn't krylon fusion, and i noticed on my test bed that if you did too thick a coat it caused the foam to expand a bit, light coats had no problem however. I think if you can get your hands on it the krylon fusion spray should be perfect.

The black is actually this rubberising spray i had lying around - turns into a layer of rubber which should be pretty resiliant (given it's the front of the airplane i thought that'd be a good thing.) I was suprised it didn't destroy the foam on my test piece, but the underlayer of krylon probably helped with that.

Wedgewing - cheers matey, looks like i do have a rough idea what i'm doing lol.

rusty, Want to pick up some cheap speed.....put a 10x7E, APC it really picks the speed up even on the stock motor and esc....good luck and keep'm in the air!!!!
