My UMS 7-77 is now well over 10 years old. Still going strong....sadly, it’s the owner thats showing signs of fatigue!

Hi Manu cc I push oil into the cam ring when I get home. I've never tried fat.
If anyone here on the forum has used grease for the cam ring on 7-35.7-77.9-99 so tell us

OK, merci.
Je demande, car je suis en train de faire la révision du mien, et d'origine y a de la graisse blanche.
Et à chaque fois que je démonte un poussoir après un vol, de la graisse en sort avec la pression qui se créé dans le carter de distribution.
J'ai tout nettoyer, maintenant je sais pas si il faut remettre de la graisse, ou continuer à mettre de l'huile après chaque vol.
J'ai contacté UMS, mes pas de réponse.

Congratulations.
Great work there.
WOW! And I thought I was doing well. You fly it yet?
How are you mounting the radial? I'm still trying to figure out how to mount my 7-90.

I'm sure this has been answered 1M times, but whats the grease coming from out of the radial near the pushrod base? There is a decent amount that comes out everytime I run it. Is it a defect or a feature??

Are there any issues with mounting a 7-90 90 degrees to the side?

Voici le montage que j'ai fait pour le 7-77, une première plaque de 10mm collé et visé sur la cloison moteur, et une deuxième plaque de 22mm qui a la forme du support moteur
