Sparky, Kwik had his say and I had mine... I still love him and no hard feelings I hope

Absolutely no hard feelings.

Jimmy, I have a thread on my engine here, in case you are interested;

Thanks I will take a look....thats a great place for scale detail

How is everyone doing with the electric retracts so far?

What I have learned from all these threads on retracts.

1.Voltage, Voltage, Voltage, the sweet spot seems to be 7.4 2S 25C 800-2000mah
2.Upgrade tires, get rid of foamy's
3.Toe Out the wheels 2 to 3 degrees
4.Make sure Robart control box is on correct settings are plugged in with correct polarity. Failure to do this causes issues?


Did I miss anything???

I am quite happy with the Robart electrics - they have worked quite well so far - 2S Lipo 3600. I am using the high capacity battery since I am also driving my auto start off the same 2 cell.

I was using the Williams Bros 14600 wheels but they flatten out too much and on landing I had two near nose-overs due to friction against the pavement. The plane does not even roll easily when I push it. I have gone back to the foamies until I find something else. Folks have recommended the 12200 here so maybe I will try those.

I have tried toe-out but I can't say it did much for me. I found that putting the tailwheel on a separate independent channel and reducing travel will dramatically improve ground handling. I may add some more toe-out as well. My P-51 and P-47 have much better ground handling than this plane.

I use the 5" Dubro treaded lightweight wheels. They are inexpensive, durable, and fit fine. They don't look as scale as some of the skinny Williams bros. wheels, but they work just fine. A bit smaller diameter than the stock (5.25") but that gives you a bit more clearance on the wheel wells that can cause less problems. Here's a photo of them on my plane. If you painted them black and added some detailing they would look more scale.

Re -The only modification I've made was to add epoxy and some 1/4 inch rails under the saddle area. and that seems to have been the fix.

could you post a pic please ?

Ok, so any word on how much the Saito mod costs?

Thanks for the idea. I will try them out!

Have you tried filling the tires with foam?l

Hi, this is a good idea. I had this idea before but my guess was that the tires would be tough to take off. I will try it now though since you brought it up. Thanks!

I think I have the same Wheels as you, although I get the 14600 and 12200 mixed up; are the 14600 Wheels the ones with the more bulbulous Tire Profile, the Tires are actually slighlty wider than the Rims, whereas the 12200 Wheels the Tire Profile is tapered and tapers narrower than the Rims?

Either way, let us know how you made out filling them with foam, how you did it, what you used, etc; I'm still building my FW190 but I thought that the Wheels/Tires were a bit too soft/squishy; others are using these Williams Bros Wheels, how are you finding them?

Thanks, Doug.

My 12200's have been fine. They're pretty solid.

dasintex

My Feedback: (10)

Are your 12200 Wheels the ones that have a tapered tire Profile, a cross section of the Tire would look like a rounded cone?

My Feedback: (45)

Yes

Ok, to Electric start or not??????

who is enjoying the electric starters??????


too much maintenance or worth the work?

Here is what is cool about electric starters IMO ....yer airborne flying about before the spectators and you kill the engine and holler " DEAD STICK!!" Then as you make final and cross the threshold, you hit the starter and zoom away leaving the spectators slack jawed in awe��. Otherwise, unless you have a crappy engine that's hard to start, I think it would be a pain in the hiney Bo

I talked to the owner of William Bros Products 'Dan Brett' who took over the company in 2005; I asked him about the wheels we were using and how some found them too soft, flattening out on landing, etc.

He said depending on how old they were, 1 of 3 three things may be going on; 1) No Foam Inserts; or 2) Prior to 2007, softer low density Foam was used; or 3) After 2007 Stiffer high density foam was used.

The Foam currently being used since 2007, is a dense Closed Cell Backer Rod/Cord filling the tire cavity completly with the right sized diameter Foam Cord.

Dan said to give him a call (512) 846-1243; if the Wheels are not working out, he would like to have a look at them, see if they have foam or the softer foam, etc and work out a replacement if they were not up to current standard.

As far as trying to fill the Tires with Foam, Dan said the Wheel Halves are Glued together and accessing the tires is not possible without breaking the wheels

I would like to say that yes.. there is a thrill factor cutting the engine in flight but what's really great is starting the plane from the pilots station as opposed to starting it and walking over to the pilot station to fly... plus.. I'm old and my elbow and shoulders sing after a day of flipping props... while my index finger never gets strained

Dasintex, the last posts about tires was #2700, I think. And your tip about them back then made me order the 12200.

I have the 12200 now.

They are NOT the conical type. 12200 is the round type, looks very much like the Fw 190 type.

I like them a LOT.

Putting on the 12200 wheels trigged two belly landings; One wheel didnt want to deploy.

Reason; The wheels were pushing against the bottom of the wheel well. That makes it difficult to "unlock" when you want them "out".

So I had to shims the mountings inner part, to avoid the wheels touching the bottom of the wheel wells.

Kwik;

I still get it confused, I have the same Wheels as you do for my FW190; I havn't flown mine yet, still building mine, yeah it takes me forever, I get sidetracked often with other projects.

However, I do have the Wing completed and the gear extends and retracts without any problems getting stuck in the retracted position, mind you thats on the work bench and not in the air; prior to you shimming the mounts, did your gear work without any problems on the bench as well like mine, but got stuck when the plane was in the air? are you using electric or pnuematic retracts?

I don't know the number of mine any more, but they are the conical shaped ones. I've had no problems with flattening out. As for the electric starter, while it would be cool to shut down and restart in mid air, I like mine just for the fact that I don't have to flip anymore. You almost always need nose weight in a warbird anyway so why not make it useful. I'm installing one now in my 30cc Waco and will be using one on my H9 corsair when it shows up.
