Hi Volkert

Have built a couple of these (and have another in box waiting for assembly). Mine have flown OK with the motor mounted on the firewall with no side or down thrust. Think most have mounted this way.

As far as aligning I ignored the marks mounted the fuse vertical (fixed it to the back of a chair and shuffled the motor and mount around until aligned with the cowl. I then carefully removed the cowl and marked up

Volkert I have the Corsair and the P-51. And I mounted mine to the firewall. Both fly great. I have the 190 on the way. Gonna put a dle 35 in it. And plan to mount it the same.

I mounted my PTR 36 in a similar fashion. Put the fuselage vertical. Set the motor without the spinner on the firewall.

If your cowl is tight, put wax paper between the cowl and fuselage. Then place your spinner backplate on the crank and adjust the motor. If you slip it off carefully, not disturbing the motor, then you can mark the motor mounts positions.

It is about complete! I cycled the ESM electric gears a couple of times and guess what: it failed! Looks like the gears stripped.

When I ordered them reviews were OK. Now I read about other unhappy campers. So, what is best? Go back to air and get a set of Sierra's? Any other offering of electric retracts? Hope ESM will deliver their V3 version?

Go Sierra's and relax but run the wheels that come with the kit put them on a lathe and round the sides slighty with sand paper and they look great i watched the ESM ones on a test personaly i thought they where junk . Have seen four of there sets fail to date

Volkert,
I had my ESM gear modified by Down and Locked http://www.downandlocked.com/.  I've been very happy.  Reliable and they have great customer service.

Yep, these guys are great! Wished I had them around the corner. If all else fails, I will probably send my retracts there. Will take time though (including mail to/from Europe).

Hi All,

I haven't contributed in a while because my electric 190 has been in retirement for just over a year. Revisited the plane and have had a half dozen flights this month, and finally got a decent movie, shot by my great mate and cameraman Bob.

She flies just as well as I remember, so here is the link to the movie. I hope you enjoy it.

Al,
Nice video! It really is an art to get everything right. Al, I must admit you were my inspiration for converting mine to electric. I used your same set up with 8S. I was considering switching to 10 cells. I have enough power for scale flight but I'm swinging a 22X10 prop to get enough watts since my plane is so heavy at 19 pounds. Pretty high Amps at 65 with bursts to 80.

I had a fun day at the field yesterday.Its still very touchy on the elevator though. I have 15mm of throw. Manualcalls for 25mm.I tried expo too, then backed off to none. Plane balanced at 135mm, manual says 140mm. I thinkI will try 130mm and see how it likes it. Where are you balanced? Perhaps I'm stilla touch tail heavy still. Plane looks very nice in the air and flies pretty rock solid once you get everything trimed and set. Pictures below.



And another some more





I have the gear doors pulled off from previous flights. Wet and muddy field with the monsoon season here in Thailand. I've had a few little mishaps but nothing I can't repair.





The one nice thing I like about bashing these ARFs is that you can do a color scheme that no one has. I haven't seen anyone do the "Pips" Priller bird in a large scale. A real head turner.



One more thing. Feedback for anyone building this plane or any other ESM for that matter. I tore or damaged the gear plate/ribs of this plane 3 times. OK, Ok, my landings or in two cases ..aborted Take offs into soft muddy grass were not pretty but muddy grass tore them loose. The balsa for the leading edge (forward part of the landing gear bay) is real spongy and soft. The ply actually separated and pulled loose twice. I glued the leading edge back with CA to harden it and then CA'd and reinforced everything (ribs, plate etc) with milled glass Epoxy and some FG. No more problems. The greater surface area with the epoxy fillets around the joints did the trick. I'd definitely reinforce and beef up this area if I build another ESM plane.



For Flaps I've tried 15 degrees and none for Take Off. None really required. For landing I use 58-60 degrees. No real pitch change and it slows the plane down fine.



Cheers,



Jason

Jaspn, don't forget: flying electric means no fuel! I'll be hauling around a pound of fuel at take off. So moving to 130mm for CG might really help you. Maybe some other electrics can chime in.

Great pictures!

Hi Jason,

Great photos and an equally impressive colour scheme[8D].

The CG on mine is at 140mm. I too have found that the elevator is sensitive with the flaps and wheels down, but I guess that I have got used to it. Having said that, you can see on the movie that I had a couple of "bites" at the landing!!

I have 3 other FW190As, the FMS 1400mm one, the ST Model 1200mm one and the FMS 800mm one. The first two have retractable wheels and flaps and they are also pitch sensitive during the landing.

I'm sure that moving the CG forward to 130mm will make it less sensitive.

Hope this helps,

Al

Jason,looked at the pictures again and looks like you did a great job on the pilot figure / cockpit. Could you show a detail picture + story on what you did?

You electric flyers should not forget that every electron you carry adds 9.10938188 X 10(-31) to the mass of the plane

Think of what that does to the CG when they start moving from the battery to the motor!

Yup.....but the CG doesnt change with fuel usage with electric since there is no fuel usage.

Kahlog,
True, True. I here ya!....But I think they are using some ironic gas usage humor...[X(]

Volkert,
Thanks for the compliment. I'll post some of my cockpit details below from my Build Thread over on RCSB. If you want more you can go to RCSB and check out the whole Bash build. You can Register (free) to view, but if you want to post more than 5 times then you will need to subscibe for $20. Well worth it IMHO.

I'm using a DBalsa cockpit kit and I'll need to determine how it will fit with the servo tray located in the fuse. This first part will go quick since I've been building on it for a little while. First was cutting a hole for the cockpit kit. A dremmel cutoff wheel was indispensible for this. I then had to figure out the placement for the cockpit deck. I had to get it as low as I could without interferring with the servo tray. I decided in a little higher than scale location for ease of installation without removing too much. After some trial and error it fit OK. I threw a 1/6 scale Dragon pilot to check for depth. Pic below. I later trimmed the back of the seat down to look more scale and installed the rest of the kit. Quite a few things were not very scale with the kit, but it was a starting place to add touches. It's no INZPAN kit but it works for an ARF and adds quite a bit. I wish INZPAN made a 1/6th scale kit. (I now know that I Fly Tallies.com offers cockpit parts for a great looking cockpit.
http://www.iflytailies.com/store/instruments/1-6-scale-warbirds/.)







Here's the pilot test fit. The height looks about right. I later removed some stuffing from his chute so he would sit better in the seat. Here's a picture of the man himself "Pips" Priller. Remember, I cut the seat back down in later. It was too high. It's not the most scale cockpit in the world, but for a Bash in an ARF I was fairly happy with the outcome.





Here's the rest of the cockpit put together. I cut hand holds out and sunk the REVI sight into the dash. The kit directions had it mounted to the front so it stuck out, but I think the embeded position looks more scale.








Cheers,
Jason

Hey all, sorry to jump in and ask a likely redundant question but I've searched through a lot of the 107 pages and at this point am throwing in the towel! I have an older gas engine I really want to use ( a Weber Bully 35 some that a few RCU guys helped me get running ). It is a strong runner, but a bit heavier then the newer breed of gassers. My original plan was to use it on the ESM Val, had one on order, then it went back order with no word on when they might be in stock. So now I am looking at other round-cowl war birds that need nose weight and am kind of down to choosing between the 190 or the F8F Bearcat. Reading through the posts, I see that the earlier version with the molded wings was heavier and needed more ballast up front. The newer built up wing version is lighter, but I didn't see how much less nose weight was needed. When putting the Bully on the scale, it comes to just about 4 lbs. ready to run (muffler, ignition unit, spinner, prop - basically pulled from the test stand and put on the scale). It seems the bearcat has a shorter nose and needs A LOT of added wt. but the 190 looks to have a longer snout, any one know or have an opinion whether the bully would work in the 190? Or at least have a motor/added weight combo I could research?
Thanks!
J

The 190 does NOT have a longer snout then the bearcat. Not by a long shot. The 190A is a very short front end. A 4 pound motor would work well up front on the 190. I put in a saito 180 and everything related to it in front of the cowl.....ie...throttle servo, onboard glow, and even the RX battery and STILL added at least 12 oz or more of dead weight lead.

I mounted a Laser 200v @1220 grams but will still need a lot of lead to get to the right balance so you should be fine with that motor.

Thanks Kahloq and Volkert, are your's the built up wing versions?
Guess I spent too much time looking at the stumpy (almost caricature) profile of the bearcat, that and subconsciously calling up images of the Dora I just remembered the sleeker looking 190 (in any of its models) as having a longer nose. The bearcat is 5" shorter, but you would think that would make it less tail heavy, but from what I read that's not the case. Anyway, back to the subject,,,
Volkert, how did the laser fit in the cowl? The bully is side carb and exhaust, just wondering what kind of clearance I would have.
Thanks,
J

Mine is the built up wing. The actual wing itself doesnt really change the CG muchwhether its composite or built up. The composite just is heavier....though there is maybe like a 5-10mm difference in CG. Ive got mine balanced at 133mm if I recall

Ya thats the part I wasnt sure of, I knew there was a difference, but couldn't tell how that effected the nose weight situation and all the magneto (i.e. heavier g38's etc, though the bully is electronic) motors were being discussed farther back when the older style was in use. Just wanted to make sure there wasn't a significant shift that would make my motor a bad choice. Other then that it sounds like a good flier? It can handle the weight? Ive always flown warbirds, but am new to gassers and have stuck mostly to "sport scale" hangar 9's, etc, that fly more like sport planes with only a couple of real "warbird like" planes that took off and landed much at the same speed (and held breath)! Not looking for a floater, but want to stay away from a white-knuckler till I get more familiar with gas (kind of the impression I get from reading about the bearcat).
