winsor68 Posted August 31, 2011 Share Posted August 31, 2011 Do you reckon these engines would be a possibility for Aviation conversion... say for a 95.10 aircraft... say something like a 95.10 Sapphire? http://subarupower.com/pspecsheet.aspx?pid=225 I know many years ago Subaru/Robin engines were used in Ultralights.

Guernsey Posted August 31, 2011 Share Posted August 31, 2011 The 28hp model could possibly suit 95:10 aircraft that performed satisfactorily with a Rotax 277 , the Winton Swing Wing for example, however there are very few 95:10 aircraft around and the Sapphire was better equiped with the Rotax 447.

There seems to be a fair number still around... and as a build project 95.10 seems like the perfect category... the problem seems to be the lack of Rotax 447 engines left in circulation with no real alternative.

Guest ozzie Posted August 31, 2011 Share Posted August 31, 2011 The Backyard Flyer uses a similar generic V twin. It performed well and sounded great. http://www.culverprops.com/big-twin.php Link to comment Share on other sites More sharing options...
winsor68 Posted August 31, 2011 Author Share Posted August 31, 2011 Thanks for that Ozzie... That Valley Engineering engine looks great... All the hard work done and a good price. Link to comment Share on other sites More sharing options...

fly_tornado Posted August 31, 2011 Share Posted August 31, 2011 flying 5 knots above your stall speed will only work for a while. you want power and lots of it! Link to comment Share on other sites More sharing options...
Guernsey Posted September 1, 2011 Share Posted September 1, 2011 you aren't going to get too far on 28hp! At the end of the video the specs stated that the engine was 40 hp. I like it and at that kit price we could start a squadron of them. Bring on the 95:10:thumb_up: Alan (squadron leader) Marriette. 1 Link to comment Share on other sites More sharing options...

Guest ozzie Posted September 1, 2011 Share Posted September 1, 2011 Yep mate sure does ... what does the Lazair have ? Isn't it between 10 and 16 HP .David 11 total maybe on a really good day early in the morning. I had an early single seat Thruster with a 277 on it. Required a gentle touch. But it went as far if not further than a Thruster with a 503. Link to comment Share on other sites More sharing options...
Guernsey Posted September 1, 2011 Share Posted September 1, 2011 My Winton Swing Wing also had a Rotax 277 and did 50 kts at 5,000revs, 55 kts at 5,500 revs and 60 kts at 6,000 revs. This aircraft is still performing well with it's present owner at Renmark, SA.

Litespeed Posted September 2, 2011 Share Posted September 2, 2011 What about a engine designed for a aircraft instead of a mower? How about the Verner JCV360- flat twin, watercooled, redrive, very light and good power http://www.vernermotor.com/index.asp?sec=42&gal=photo110404 The cost is about the same as a converted mower from the states. Approx $5000. I just think it has to be a better prospect for reliability. Displacement 360 cc / 23.06 cubic inch Bore 63 mm / 2.47 inch Stroke 58 mm / 2.28 in Compression ratio 1 : 11 Maximum power 35 BHP (25,7 kW) @ 7800 RPM Max. continuous power 26 BHP @ 6000 RPM Torque 33 Nm @ 7000 RPM Propeller rotation CCW, viewed from the front (tractor propeller) Weight dry weight 26,4 kg Spark plugs NGK CR9EK or equivalent Spark plug gap 0.5 mm (0.02 inch) Electric starter 18 V/370 W Generator (Alternator) 12 V/100 W Lubrication semi-synthetic 4 stroke motorcycle JASO MA/MB oil Fuel motor petrol, octane number 95 Fuel pump vacual Mikuni Carburetors 2 × Walbro WB-37-1 Reduction drive 2,76 : 1, via belt (width 42 mm, length 610 PJ) Propeller hub ø75 - 6 x M8, ø70 - 6 x M6, ø50 - 6 x M6 Weight cooler - 0.74 kg, oil 1l ~ 0.8 kg, watter 1l ~ 1 kg, exhaust - 1.6 kg 1 Link to comment Share on other sites More sharing options...
