I fly a Talon - an ultralight-type E-LSA, powered by a 582. I need a new radiator. I've been told that it's not necessary to buy a new radiator from Rotax - that a car radiator will do every bit as we ...

The 503 was discontinued last year. According to Phil Lockwood, at a forum at Oshkosh, Rotax is committed to continuing to supply parts for all discontinued engines for 10 years after they go out of p ...

Does anyone know if the 447 and 503 have finally been discontinued? I noticed that BRP no longer lists them on their web site, i.e. at:

Though I never had that problem with my warp drive (68" 3 blade), I now have a powerfin F model (70" 3-blade) on my tornado/912ULS and it's smooth as silk at idle and shutdown.

I did talk ...

Well here I am having to correct myself on a post. I had heard from a top person in Rotax about the lack of ZDDP in Aero Shell Sport Plus 4. You would have thought they knew. But I just had someone se ...

Hi Dick,

I too knew this was a loaded topic so I put on an extra layer of skin, but couldn't see any reason to hold back. I heard that the reformulation won't take place until 2012. I truly don't k ...

For the guys that come to me I will not recommend Aero Shell any longer until it is reformulated. For the guys that need a semi synthetic I will recommend Golden Spectro 4 motorcycle oil (10-40W or 20 ...

Hmmmm... lots to think about. I don't mind trying to guide the plane off power and wouldn't automatically pull the chute in haste, but it is good to have just in case while flying over the mountains i ...

Thank you very much for your help Sir, as I have fallen short trying to find anything on the 447. I just want to ensure the dependability is there, and support is around when I need it.

Very respe ...

I just heard that the company supplying Rotax with the new fuel pumps just back ordered them. That means they could still be a month away. It's a wait and see.

So does this new fuel pump mean the o ...

Hi Lucien,

Just drain a little coolant down below this level, pull back the clamp and hose. Then unscrew the 2 screws that hold it down. It is far easier to remove it than mess with everything else ...

Hi Lucien,

It happens once in a while, but not real common

Hi Roger,

Is it just my imagination, or does it look like I'll have to take the intake manifold loose to unscrew the elbow? Seems li ...

It's not the "O" ring. It is leaking around the threads. You should be able to re-use the "O" ring.

Take off the fitting. Take a heat gun and warm up the part and unscrew it out ...

Hi guys,

I have a very slowly developing leak at the upper coolant elbow on my #1 cyl on my 912uls. I've attached a picture of it (if the attachment goes through that is). It's a very very slow ooz ...

I have been adjusting, then flying the RV-12 with trial and error Sensenich ground-adjustasble prop blade settings. I believe I now have the prop about where it should be. Here are the results of to ...

Hi All,
HMMMMM!
THE IDLE JET AND or CIRCUIT may be restricted.

lol... this is exactly what happened to the other titan on our field after he did his carb rebuild. When they were doing the bala ...

Hi All,

Thinking ahead.

I'll give this scenario and see if someone can tell me what the problem is and where to look to solve it. I'll give it a day or two for answers then I'll give the answer ...

I am looking for another hole to mount an additional flight instrument in a Kolb Firefly panel. I’m considering removing the dual EGT gauge and the dual CHT gauge, and replacing with a combination ...

Isn't the idea of syncing up mean to match one to the other??? Wouldn't you just adjust 1 carb to sync to the other??!!!
