Excellent engine, reliable and powerful, ... only the propeller plate drive needs to be reviewed (brittle!). Thanks to AMAINHOBBIES for their assistance ...

Thanks for the prompt delivery. The initial back order delivery date was mid-December, so I was pleasantly surprised by the shipping notification. The engine arrived well packed and in great condition. I have test fitted it to my current model build and will do preliminary run-in on my test stand before final mounting and fine tuning in the plane. I expect great performance from it as with my other OS engines.

Mike McConnellVerified owneron O.S. FS-95V Ringed 4-Stroke .95 Airplane Glow Engine

It took 8 days before the engine was shipped and 3 days to arrive. I just ordered another engine from you and expect the same result. I usually order from Tower Hobbies but Amain had the better price. Amain should consider Tower's free shipping practices. 8 days before a product is shipped is not acceptable. Mike

I haven't had a chance yet to run the engine, but if it performs as well as my other OS 4-stroke engines, I'll be a happy camper. The order from AMain hobbies was received in a timely manner and the price was much better than some of the other big mail order companies.

What reviewers say

Reviewers generally describe the O.S. FS-95V engine as reliable and powerful, though one has yet to run it and another has not tested performance. Reviewers praise the packaging and condition on arrival and report favourable pricing from the seller. Shipping timing is the main point of disagreement: one reviewer was pleasantly surprised by a quick shipping notification, while another reports eight days before dispatch and three days in transit, and criticises the seller's shipping speed relative to a competitor offering free shipping. One reviewer notes a brittle propeller plate drive that needs attention.

  • + Reliable and powerful performance
  • + Well packed and in good condition on arrival
  • + Favourable price compared with other retailers
  • + Pleasant order handling for some buyers
  • − Eight-day wait before dispatch for one order
  • − Brittle propeller plate drive
  • − Shipping speed criticised relative to competitors
