macey2kk Posted August 23, 2010 Share Posted August 23, 2010 well, after much ear bending, pleading, and impatience on my behalf ive finally been and picked up my rotron today....and now im the proud owner of a 294 rotron monster!!!. im a little aprehensive of the power as ive not really experienced torque effect, so steady on the throttle for a while!. id be interested in any comments / advice from 294 owners ( are there any over here ) on handling the extra power and take of techniques etc if any different from the norm. but other than that im looking forward to a more economical and smoother flight than the teeth chattering 2 smoke! roll on the flying weather! --- loop the loop being quite apt if i dont steady that throttle lol Quote Link to comment Share on other sites More sharing options...
Farmer_Dave Posted August 23, 2010 Share Posted August 23, 2010 Nice one Macey. Look forward to the fuel burn figures you achieve from that one. Been watching with interest, but not seen any actual data yet. It's obviously very powerfull though, so take care. Sounds awesome too.

scottishmotorman Posted August 24, 2010 Share Posted August 24, 2010 For a nil-wind take-off use between quarter and half throttle and you'll be off the ground in a dozen paces. On a reverse take-off a quarter is all you'll need. Because the battery usually charges to full in under 30 minutes I carry an inverter in the car and can charge it on the field if it needs it but truth be told I get over 20 starts from a single charge. Good luck and happy flying! Quote Link to comment Share on other sites More sharing options...

Good luck and happy flying! i couldnt remember who it was that had one, now i remember its your good self... have you fitted any kind of restrictor to the throttle anywhere or are you just using a finger behind or something to limit the travel?... how do you find it when airborne?..have u ever used full throttle or do you find it puts you close to a stall?.. do you have any tips for avoiding stall?...if im honest thats my main concern when in flight...i use a synthesis 34....and on reflex trim it does sink alot so i suppose it may not be as easy as im worrying about....but i dont think id like to hit it full on slow trim!! thanks for the reply...and you simon...i hope mark is getting on well with my old macro now!

skyraider Posted August 25, 2010 Share Posted August 25, 2010 Brilliant, please do not place your reserve in front of the radiator or you may see the red light blinking. Nice of you to treat yourself to a Rotron. Mark Quote Link to comment Share on other sites More sharing options...
psymon Posted August 25, 2010 Share Posted August 25, 2010 It's a fantastic machine, I just took my very first flight on my 294cc, was abit wary of the power but take off was not a problem at quarter power and I am over 18 stone...

macey2kk Posted August 25, 2010 Author Share Posted August 25, 2010 well my reserve is front mounted so no prob there... and nice one psymon on your flight...i reckon quarter throttle should do it for me...as we are similar weights and my wing is a synth 34.. just need some sodding sunshine and less wind now!....great british weather...not!

I find the throttle has enough spring in it not to warrant any kind of restrictor and that I seldom go to full throttle - it's just good know that the power is there should you get into sinking wind or need a bid extra for a nil wind takeoff.

aquatix Posted August 26, 2010 Share Posted August 26, 2010 Fantastic piece of engineering and better looking than my missus ! Must be nice to fly without the 2-stroke vibration ... Bit puzzled by the quoted performance figures though - the 294 has an expected leap in Hp over the 160, but not such a correspondingly big increase in static thrust. Is that simply a limitation of the swept volume of air ? Also, the Everest version develops monstrously high Hp & thrust for the same size engine (294cc) but has a much higher fuel burn rate. I'm obviously missing something as with that power I would expect it to be on tickover for normal flight, with the throttle being virtually redundant ?

Neilzy Posted August 26, 2010 Share Posted August 26, 2010 I believe the Everest version was super charged Gilo had very cleverly grafted a turbo unit onto engine and drove it via a belt and result was a super charger unit.

alan_k Posted August 26, 2010 Share Posted August 26, 2010 As I understand it the Everest version was supercharged in order to get enough thin air in. Cheers, Alan Quote Link to comment Share on other sites More sharing options...

aquatix Posted August 26, 2010 Share Posted August 26, 2010 Clever little sod!!!!!!!!!! Indeed ! By my rough reckoning thats 313 Hp per litre, which wipes the floor with any automotive engine (not sure what the world record is ....)

psymon Posted February 21, 2011 Share Posted February 21, 2011 Factory Fresh !!!!! Shame it has to go but i prefer racing than flying and the wife and kiddies think doing 150 on track is safer than flying at 40mph lol Cheers Simon. Quote Link to comment Share on other sites More sharing options...

I don't think my wife and kids like the idea of me flying up in the sky at 40mph......Or doing 150mph on the road on my Suzuki Hayabusa....But I'm not giving up either of them!!! Neil..
