Looking for a spinner
 

I have the Hangar 9 P40B Warhawk 50. I am looking for the 2 blade 86mm nylon spinner. Anyone have a spare for this ARF or have another one in another color like red or black? I can't seem to find them anywhere unless they are carbon fiber. I don't want to pay those prices. I would even think a 3.5" (89mm) would work too. I doubt 3mm will make any difference. At least not to me. Thanks.

sideoftheroad Might I suggest that since most P-40s use inverted engines and that combined with plastic spinners very often end up with those nasty black rings Perhaps its time to step up to an aluminum spinner. If you must use plastic then definitely the color to use is black as this tends to hide the rings.

TLH's link above shows some aluminum types (I also would avoid the carbon fibre types) and here is a link to the Dave Brown Vortech spinners:

Thanks for the input John. $40 is more than I want to spend on a spinner though.

Go black then:cool:

Great Planes offers a 3 1/4" spinner with an aluminum back plate and a nylon cone in white, red, black, or yellow. They are available thru Tower Hobbies @ about $15.00. That's the largest "plastic" type spinner that I know of. Larger than that, you will need to go to the more pricey aluminum type. "If you wanta dance, you got to pay the fiddler".

Why do people not do their own research before posting on this website?

This site exists to ask questions and learn from others,, isn't that research?

Mecoa is not a very well known vendor,, I'd venture to say many seasoned modelers don't know those CB spinners are still available there.

Flycatch. I had 2 objectives in my post. One was in hopes that someone else had or has the Hangar 9 P40B Warhawk 50 ARF that might have bought a couple extra 86mm spinners that was made for this plane and might be willing to part with one. The plane is long out of production and they cannot be found anywhere. Part 2 was if part 1 wasn't possible to see if anyone had resources for a spinner of similar size that I hadn't already looked at. After all I did state I am only finding carbon fiber for that size which I didn't want to pay those prices and I'm looking for nylon. Even if I hadn't done the research, sometimes it's much easier to reask the question over and over and over again vs spending hours digging through a bunch of info looking for a needle in a haystack. I've already gone through the hangar 9, horizon hobby, dubro, hobby king, ebay and other sites to name a few before posting this. I didn't know mecoa had spinners and have no idea who Dave Brown is so I didnt know that site even existed. I usually say what is on my mind so quite frankly responses like that just turn people off to the hobby altogether. I am a couple years young in this hobby so my questions will seem basic and anytime I can get help is always much appreciated. Now that I've received help next time when someone else needs help with a similar question I can pay it forward with the information I've learned. As stated before isn't that the idea behind the site, is to help each other out?

I have a new uncut spinner for this plane. You can have it for what I paid plus postage. Let me know if you want it.

Craig,
I responded to your PM. Thank you.

Hence the lump of coal.

Hey sideoftheroad you needed to make no explanation to that rude responder in post #8 who had nothing to contribute and apparently seldom does other than contempt for this website.

I do hope I contributed also and by the way The Great planes plastic with the alum backplate that 52Larry mentioned and the CB alum backplate plastics that Scaleonly linked are much preferable over the all plastic types. This is because there is less of the problem of the backplate deforming during tightening and there is groved capture ring in the alum backplates.

John. Yes you have helped. I wasn't sure what you meant by the black rings though. Also correct me if I'm wrong but the CB spinner, aluminum spinner or any for that matter that you have a screw at the end of the cone, is that just for gas engines or can that be for nitro too? I wouldn't think it would matter but I'd rather ask than not know.

The cb spinners come with an adaptor nut for nitro engines

Hey sideoftheroad Yes the single center screw through the cone to an adapter thats screwed onto the end of the crankshaft is the best type of spinner. Sometime long,medium and short adapters are avalible to suit your components and yes this method has been used since the begineings of Nitro engines.
My apologies on the black ring thing. The black rings are endemic on plastic spinners and very difficult to avoid especialy when an inverted engine mount is used. It is caused when a starter is applied to an inverted engine that may not be properly cleared, as the result is the ugly burned in black ring. And I was serious if you go plastic do choose black so this will not be so noticible.

John

Sideoftheroad, Looks like by group action you have several choices to resolve your problem. If I were you I would go for the 3.5" red P-40 spinner from MECOA as suggested by scale only for me. A lot of p-40's had red spinners. I also didn't know MECOA sold spinners, so we all are learning from your question. BTY the black rings that John referred to are score marks that can occur when your electric starter cone slips on the plastic section of the spinner. If the spinner is all aluminum the score marks don't happen. Careful use of the electric starter (and a good rubber insert) will minimize the black ring problem. And lastly, the spinners with a single center bolt are fine for glo engines.

Opps, looks like John and I agree on everything except spinner color choice. He is correct that with a black spinner the score marks (rings) will not be visible. I still like the looks of the "red nose" at least at Christmas time! :cool:

If you use a silicon insert in your starter, it will not leave marks on the spinner.

I've looked at the Mecoa site from time to time at engines and parts. I HAD NO CLUE the CB spinners were still available from them. I've been modeling off and on since "75". I think of Mecoa as an engine vendor only. Time to change that attitude;):D

I have used a number of them in the past and they have some advantages first and formost is the capture ring type back plate and the plastic is thicker than that from some others. One down side is usually depending on your prop size normally some custom grinding will be necessary in most sizes. And of course sooner or later most folks are going to burn a ring regardless off the starter insert especially if the airplane is an inverted installation.

John

A silicon insert will not burn the spinner. Inverted or otherwise.

Yes indeed if a starter is carelessly applied to a hydralicallly locked engine the insert material will make no difference. I use nothing but silicon inserts but they are not fool proof.

John

I've been using Magnum silicon inserts, (the white one), for 14 years and haven't marked a spinner yet. Nylon, aluminium or carbon fibre.

What colour insert are you using?

This is an example of someone doing everything right and no of course not you will have not burn however when someone new to spinner use and in particular inverted araingements most folks will sooner or later will burn a plastic spinner Now as for myself I have no such problem since for many years now when I choose to use a spinner it will be an all alum type and my favorite types which are still avalible are either the Dave Brown Vortech's or the Tru Turn's. I keep an ample supply for my needs most of the time.

John,, most guys don't use as good a batteries as you do ;)

Actually, I've burned a few over the years,, you soon learn to clear out the engine before applying the glow and starter.

I believe its best to inform folks of all the down sides when they are making decisions to go cheap as possible concerning spinners and yes those cheezy cheap but pretty plastic spinners have some severe down sides. The biggest problem of all for the all plastic types is deformation of the back plate when tightening both the crankshaft nut but also the two or four cap screws (two blade).

John

I wonder why this is so hard to find the larger all nylon spinners and they went to the ones with the different backplate.

Not sure if it was meant for me but I have one white one for the medium sized spinners and a red one for smaller sized ones. This is what was available at the hobby shop.

The black rings that you are taking about is the reason why I started this post. I ruined the one that came with the plane I have.

The white inserts seem to be softer. I use the Magnum white cone shaped one.

I use this insert on all my models from a 1 1/2" nylon spinner to 4 1/2" aluminium which includes carbon fibre as well. Never marked a spinner yet.

Probably why I have issues using the electric starter. I can never seem to get enough grip on the spinner so I have to press in harder which in turn causes the rings. Do you have any links to the magnum insert?

No links for the Magnum. I get mine from my LHS here in Aus.

Sullivan have one that is very similar. http://www.sullivanproducts.com/Star...sMainFrame.htm It's the white one about 4 down on the right hand side. I just ordered one tonight on Ebay.

You can see the cone shape in the insert. That's why they grip so well.

sideoftheroad for the best type of insert the link that Drac provided is far better that anything else above. The Key word you should look for in the purchase of starter insert is silicon. If it only says rubber then those are the cheap ones and most likely to cause problems. They are around a third of the price of a good silicon type. A silicon insert is no assurance aginst a carelessly applied starter to a plastic spinner on a hydrolocked engine.

The top one listed in that Sullivan link is a rubber type and the type to be avoided but the second and subsequent few are the good ones.

John

I didn't know CB still made spinners, I had a big box of them and have been using them for years but finally ran out of them. With gas engines I hand flip so getting a mark isn't a problem but I used a white CB on several of my glow engines, same spinner, different engines. I didn't mark it but I sure melted a nice groove in it. The Kaos didn't care about it though so I kept using it. I would have never looked up MECOA either, it's not a go to company so I never think about them.
That's another reason for this site, it's reminds us of places we forgot existed these days.
I'm glad CB is still around, time to stock up on spinners again. Thanks for the info guys.

I recently bought the white one (4th one down) to replace the one they came with the starter I have and also have the red one (5th down).

Do you guys find it harder at first to use them to start new engines and easier once it is broken in or no difference?

Naturally a new engine is harder to turn over, but as long as I get a reasonable amount of pressure on the spinner, I find it's not too much different.

No problem GB
