I just got my 190, havn't started the build yet, getting some ideas, I will not be taking the Monokote off, the Splotch Decals provided by Top Flite look kinda of dorky, what have others done, from what I recall in some pictures, they were not used at all, others look like they made their own out of Flat Olive Green Monokote; I was thinking of airbrushing my own on to the Monokote, problem is matching the color to the Monokote, unless someone had done this and would be so kind as to share the color name, number, etc; anyways, I have read this thread through and through, excuse me for a bunch of questions, one feature missing with the RCU upgrade is the Gallery Feature to view Pictures posted in this thread, so bear with me for your kind indulgence in reposting pictures. thanks.

...so I have a coupla quick questions, if I may...
What Hitec Servos (or others) are a good equivalent to the Futaba's suggested in the build manual?
And retracts - I'm leaning towards the Robart Electrics - good, bad, indifferent?
TIA for your suggestions...

For servos, I used these except for the tailwheel steering.
HS-485HB Servo
For the tailwheel steering a metal gear equivelent.
HS-625MG Ultra Speed
Both of those options are for 6v maximum. If you want to run didgital servos or 7.4V you'll have to try something else.

I've been setting up HS-625MG's in my F4U, so I might have a couple spare somewhere for the rear LG. If you're sure the HS-485HB's are strong enough for the rest of the airframe, I'll see what I can source down here.
Robart are apparently having some sort of 20%-off sale, but I couldn't find TF FW190 retracts on their site - just tells me to look up 'Great Planes', and of course, they're not listing them
I like the idea of electric retracts - despite some of the negative comments - and the real one ran electrics anyways, IIRC...

Cooling Fan/Spinner
A couple quick questions and some feedback in regards to the use of Cooling Fans/Spinners; from what I have read, this plane needs some nose weight, the Spinner/Fans available from SIST or FIGHTERACES I have been told, are lighter than the decent Spinner that comes with this Model from Top Flite; however, I am considering the Electric Start from SDS, MilehighRC; which will add usable needed nose weight, thereby countering the use of the lighter Fan/Spinners. For actual cooling of Engines in our planes the Rule I have always went by is 2 times the Exit/Exhaust Opening/Venting versus the Intake; obviously the Intake is limited on the FW190; if you use the Fan can you reduce the size of the Exit/Exhaust? the reason I ask, I have seen some large Exit Openings on some of the Posts, does the fan not Force the Heated Air out? just trying to limit the size of the Exhaust Opening; finally, if anyone has the Spinner/Fan from FIGHTERACES, would the Top Flite Spinner fit or work on the Fan Unit? Thanks.

The robart electric retracts may be a drop in fit..but if yours behave as mine have they will give you fits.
Be prepared for bent pins on the trunions and installing heavier mount brackets for the actuator mounting.
I have also recently had to remove and disassemble the motor/transmission assy to find out why one of my motors would fail to work intermittently.
Found fuzzy lint like black fod in the end cap that holds the motor contact wipers.
After many weeks of cussing and 4 belly landings. I have finally made 10 consecutive flights with no gear failures.
See my earlier posts on some of these matters earlier in this thread.

I also had a problem with my electric Robarts, a belly landing on my maiden flight due to a defective actuator. I also did the actuator bracket mod that Tommy-Gun talked about and initiated on this thread. So far all is working well and I am sticking with electric retracts, pneumatic retracts have problems also. My retracts fit like a glove, no messing around they just dropped in place.

The Spinner/Fan Unit from FIGHTERACES are from SIST, seems I might have read that, sorry about that; does this SIST Spinner/Fan from Fighteraces Fit the Top Flite FW190; Roy Vailycourt told me that his Spinner/Fan Unit from Vaily is too big for the Top Flite FW190.
Thanks

HS-485HB Servos are a bad idea.
I waited a little before responding to this to give one of the regulars here time to respond. I believe going with HS-485HB's would be a grave mistake. Although they may have a sufficient amount of torque, the gear train being that of "carbonite" is very brittle. I would suggest going with a servo that has a metal gear train to stand up to the vibration. The added benefit of metal gear servo's will also put the torque output to over 133oz per servo @6v.

Yes, those or something similar in the same class would be perfect. Without starting a servo war, this is what I used in a recently completed TF Giant P-47.

No - no servo wars plz.
Don't get me wrong - just trying to work out if servos that I have on-hand are good enough for this Beastie... or if I shoudl shell-out for bigger/better/stronger servos.
It's a decent size plane that costs a few bob. Hading over the odd pineapple or avocado more means little if it is the difference to flying comfortably... or decking it ...

Servo Question, Not servo War Question
A quick Servo Question; for this Plane, which is more important, Hi Speed Servo or Hi Torque Servo?; I am looking at either the Hitec HS625 Hi Speed with 94ozs at 6volts - VS - HS645 Hi Torque with 133ozs at 6volts; same price for either one, both types exceed the minimum suggested torque of 50oz-in; which way to go? It would seem that the way to go would be the Hi-Speed type, you get faster Action and it exceeds the Minimum, best of both? Right?
