I thought the biggest pinion available for the Raptor 90 had 12 teeth and not 13?
yep, i was wrong. I`m runing 93/12 ratio now. I was planing to get 13 tooth pinion.

What blades do you guys suggest for doing AP, and what gear ratio? 800mm blades would be oversized?

If you fit a 90 boom then I think 710 is your limit, I’m using Sab 710 wide core with a 90 boom, and I will be taking some video this weekend now the British weather has brightened up.
I don’t think Raptor do a 13 pinion but if you find one that fits I would like one.

If you are going to make something special I think you would be better with a 14 or 15 tooth pinion. Still guessing on headspeed.

I seem to remember a post about the Raptor 90 gears some time ago and they had problems with clearance when trying to use the 13 pinion.

Raptor 90 SE Gasser Video
Well it’s not a brilliant Video but at least you can see it fly’s
If the weather is nice again tomorrow I will try and get some more footage
After this flight I opened the low needle a blade width and the climb out was a lot better, less bogging.

WOW, my eyes hurt after watching that! Tell your camera man to stay on wide angle next time so its not so jerky! And I didn't see it fly was I suppose too? And dude, you had such finesse when you walked out there! that part of the video was great. I'm teasin you bro! Try again. I'm really anxious to see it fly. It might motivate me to get off my butt and get mine done.

Yeah baby! Thats what I'm talkin bout. Good Job. Sounds like shes runnin a tad rich but your getting the hang of it. Next time tell your cammera man to not zoom in and not to walk and film at the same time. Dang, it still gives me a headache to watch, but thats ok. very cool.

I will try and get some better footage later,
After that flight on the video I thought it was a tad lean because it was bogging on full power climb outs, anyway I turned out the low needle slightly and it seemed a lot better, am I tuning the wrong needle?

I'll be totally honest and tell you that I'm not an authority on the subject of the needle settings yet as my bird wasn't even broke in yet before the ground came up kinda fast on me. But there are probably a hundred threads on that very topic on this forum. And they will vary greatly. I follow Chris Bergens advice on the fuel to oil ratio and the needle settings.

It didn't sound bad to me. I just think your headspeed is lower than it could be because of the gearing. It doesn't sound to me like it is bogging. That tone change is just a load change when you slam in full pitch.Ace

I must admit it sounds better on the video than it did when I was stood under it, but after that flight I opened the low a touch and it did seem to climb easier and sounded to have more power, I will monitor the plug for the next few flights and see what its like.
The head speed is 16500 at the moment but your right it would be better with one or two extra teeth on the pinion so I could achieve 1700 or 1900, I think someone will come up with the larger gears before long but for now I’m happy to just fly around very cheaply until I improve my flying skills

I think you meant 1650 so the engine is doing about eleven, four. I wouldn't go any higher on a new engine.

Your right AceBird I did mean 1650 (slip of the fingers)
The engine I have wasn’t new when I bought it, the seller advertised it as new on eBay but when it arrived It was plane to see it had been run so I don’t know how many hours or how much fuel its had through it, the seller did tell me later it had only been bench tested and offered to stand by it should it go wrong.
Anyway I'm more than happy with it at the present settings so let’s just see how it goes for the short summer we have left.

You can always tell a new engine by pulling it real slow. If you feel compression early and it has a definate tug at the top it is new. Compression decreases as the engine wears.

OK Guys, I'm getting ready to dive into mine and get it back together. All my parts are sitting here brand new in the bags they came in. BUT, before I do, I want to get this gear ratio thing resolved. I'm not a scientist, or a machinist. I'm running the stock gears right now. When my conversion was running the last time, it seemed fine. Loads of power, stunning climb out, etc etc. Keep in mind I'm not doing 3D. This will be a camera ship running a Airfoil Pro 1 360 mount with and SLR camera. Is it necessary to change out the gears? I'm looking at the Raptor 90 manual right now. My 3 gear choices are as follows. The mains are 93, which is what comes stock, a 94 and a 95. The pinions choiuces are 10, 11, and 12. If I need to change gears which ones do I switch to? I figure its way easier to do it now while the heli is apart than when I get it all done. COme guys, hook me up with some info.

About time
Have another look at the gear options I'm using the (PV0298) Main gear 91T option with a 12 pinion.

Hi Burnt offering
My raptor Gasser is still running great but I have had a couple of problems along the way, the first was fuel starvation and after changing the gaskets and a good clean out it still let me down so I swapped the crab and now it runs fine with or without the Governor, the second problem is a bit hard to explain but after a monuver the blades and head looked to be wobbling, at first I thought it was the bad wind causing it but when the better weather came the problem stayed. The red dampers and thrust bearings were new when I did this conversion and I couldn’t think what was wrong. The only solution I’m came up with was to try some stiffer dampers so I ordered a set of inovation dampers and they worked a treat. I wonder if it was the extra weight that made the head and blades bounce like they did. Now I can’t fault the Heli and look forward to flying it every chance I get.
