Can anyone tell me what spinner to mount on this without spending an arm and leg. The stock is junk for a 16" prop and the Dubro 2 1/4" is no good also because the blind nuts interfere with the back plate. 2 1/4 is about as large as I want to go.

You will probably have to bite the bullit and go with Tru turn.I just ordered one for my Taylorcraft and i think it was 21/4 cut out for a 15 -8 prop but i think they said it would also fit a 16" prop.They cost a little more but at least you know you won't have to hog them out to get a fit.I think i paid 40$.

I used a Great Planes 2 1/4" aluminum spinner on my T-craft.I had to open it up some for a 16x8 prop but it only took 30 minutes or so and the spinner was about half the price of a Tru-Turn.

Thanks guys, looked at them on Towers web, not that bad in price. I have the interior all painted in white, servos covered up. Looks pretty good and looking forward to flying it this spring.

Ok,

One more question. The length of these spinners are 2 1/4". The hub to the end of the crank with a prop nut for the spinner screw is about 2 1/8". Are you sure this works and are there any other things I will need to do with this. Looks like it may be real........ tight. Thanks guy's

BTW, I am going to use a 16 x 8 prop. I have an APC, but the hub is thicker than wood versions. What are you using?

Hi Chook,
The OS 1.60 twin I used on my plane has a totally different method of mounting the prop compared to a Saito 1.80.It uses a threaded sleeve that the prop rides on that screws onto the drive shaft and then a lock nut screws into the center of the sleeve.This lock nut has a threaded hole in the center for the spinner screw.This arrangement probably does not stick out as far as on a normal engine so I can see where you might be running out of room with your set-up.I seem to remember that Tru-Turn may have made some special spinner mounting prop nuts just for this type of problem.It might be worth giving them a call.

Tailspin, how did you rig the exhaust pipes for the 160 twin on the Tcraft? I'd like to use the OS long flex pipes that screw straight into the head , but they are pricey. Also thought about some copper tubing to dump the stock pipes into.

Thanks, Dorin Luck

Hi Dorin,
I used some chrome plated soft copper tubing I found at Lowes Hardware that is normally used to hook up a sink faucet.It is the right size to slip over the stock header pipes using a little hi-temp silicone to seal them.I then bent them into "S" curves so they come together at the center of the bottom of the firewall.I made an aluminum bracket that screwed to the firewall and clamped both tubes to it with a hose clamp.This has worked perfectly so far and cost less than $10.

Thanks a lot , Tailspin - that'll save me a bunch of $$. What kind of high temp silicone did you use? I didn't realize that stuff would hold up to a four stroker exhaust temperature.

You can also use a 2-1/2 in. spinner which is much easier to set up with the larger props and looks great on the plane. visually, there is not much difference between 2-1/4 and 2-1/2 spinners.
