Hellow alex👋🏻👋🏻 have seen your video of the Sab Nitro heli and I wanted to know what engine it has to put on my Sab 580 helicopter and the exhaust pipe. If you could tell me, I would look for it in an airplane model store here in Spain. Thank you. Greetings. Good helicopter and good brand. video✌🏻👍🏻👍🏻

Hello and thank you. I'm really not a 580 size knowledgable guy. I have 1 580 size nitro helicopter and I've been using the OS 55 HZ-R motor with success. I'm running the Mstudio MS-603D Muffler on mine and it's been a fantastic flyer. I hope that helps!
