3DHD carries a 3" carbon spinner that is cut for up to a 20" prop for $58. The back plate is 10mm so if your using the gt33 you'll need a spacer.

Day 2 of flying went great! 8 more flights! Still haven't killed the first gallon of gas yet...

I added just a tiny smidge of rudder to aileron and rudder to elevator mixing and she will fly KE almost hands off! Really smooth and fun to fly!!!

Started to lean her out so she wasn't 4 cycling. Noticed on my last flight that if I am flying horizontal and inverted at a lower throttle setting it seems like she leans out and wants to die. If I am climbing inverted, don't have that problem. I'm wondering if I didn't go too lean, but if I make it any richer, then it will start 4 cycling again.

I noticed this earlier, that when flying inverted she seemed to lean out a little and stop 4 cycling. Now that I have her leaned out a little more, she wants to die. Not exactly sure what the deal is or if it is normal...

This OS makes so much power and this thing flies so fast!!! I'm really thinking I'm going to want a 20x6 as opposed to a 19x8 after break-in...

The forecasted winds for today (as of last night) were 6mph. It was blowing 10+ with gusts to over 20. Was nice to not even care! Tomorrow is supposed to be really nice again. I might have to bail out in the afternoon for a few hours and see if I can't finish off the gallon of break in fuel.

I was the smallest plane at the field today (by far). 2 other guys out there that fly IMAC. One of them has a 118" CARF Extra on a DA150 (man that is a sweeeeet looking plane). The other has a Thunder Tiger 122" on a 3W 170. Both of them commented on how well the Slick flew. I let the guy with the Thunder Tiger take a pull on my Slick and I think he was fairly impressed. He goes, (incredulously) "You haven't added in any mixing yet?"

I haven't had to add any mixing to mine yet either but I'm still kinda getting the hang of the plane. Maybe when I'm a little more adjusted to it I'll add some.

Did some more tuning on the os gt33 today. This thing is nuts on power!!!! Got the idle at around 1650-1700 rpm and it sounds like a mini v8!!! Left it a little fatter than I would like up the top end but that's good for the break-in cycles. Oh and also dropped the woodruff key in the grass...sunova

That woodruff key is a slippery little bastard isn't it!

I failed to mention that the second spinner broke today. Same way as the last one. Not sure why... Maybe those Extreme Flight spinners from 3DHS are only meant for electrics.

I also had my prop slip on the shaft today... Actually, the prop didn't slip, the backplate did. The aluminum backplate on those spinners are smooth on the back. That part will slip on the knurled drive spacer on the OS. Need to find a spinner that has a knurled backplate...

(I had that thing on there TIGHT... I don't think the cause is cause I didn't have it tight enough or that the wood prop started to squish... It was very tight...)

Yea I am going to loctite the next woodruff key in but also have spares.

I noticed my spinner slipped today as well. I am using a great planes spinner that I had to cut out the prop areas on. When I stopped tuning today I could see it spun enough for the prop to dig into the recess on one side. Ordered a Omega 3" as a replacement for when a put the 20x8 on the motor once its broken in.

You maynot have enough air exaust, thereby building up pressure inside the cowl. This will cause your engine to change the fuel mixture.
You may try opening the bottom of your cowl or run a static port

My slick took a hard knock today... did several tumbles back to back and must have shook loose the ignition battery enought to pull the leads out of the plastic plug/connector. I was maybe 20 feet off the deck as she was coming out of the last tumble.... no air speed and not enough attitude to gain glide speed... I did manage to put her down mostly on the landing gear... snapped the wing tube clean in two. She's repairable... just gonna take a little time.

All part of the fun I guess... I'd been getting progressively more aggressive with my flying. Just need to make sure everything is double buckled!

the way the OS is set up ...none of the spinners will work out of the box......I'm sure a good engraver could match the knurling on the spinner backplates to the OS pattern....but i bet they wont do it for free...... my brother is having the same issues with the prop/backplate slipping....personally i just dont run a spinner.

+1 on this..... i made louvers for the bottom vent opening on both my planes.......they draw out the heat and excess air pressure from the engine cowl..... you can feeling it drawing the heat out on the ground with just the propwash so i know it works great in the air.

Interesting........

So this would be more evident at lower throttle than at higher throttle?

What about the fact that I noticed that it was leaning out when inverted yesterday when I was NOT running it with the cowling on?

What is a static port exactly? Does that mean you point your vent tube into the wind??? Hehe, I have no clue... I'll do some searching...

By not work you mean because of the single bolt MOUNT?

OUCH! Hope your repairs go well!

After my battery tray let loose on day one, I went through and made sure the new setup is rock solid. Hope I don't have any batteries flying around inside the fuse ever again!

If you had the cowl off and it was doing it when going inverted Then either she is not tuned correctly or your pop off spring in your carb is not adjusted right
