Graham Bowers Posted December 26, 2022 Share Posted December 26, 2022 Thinking of slotting a ".90" sized model in the build queue, something like a Kaos90. 75.5 inch span, 1002 sq inch wing area, 10.5 to 11.5 pound flying weight. Wouldn't mind trying a petrol engine, brand new territory for me though. Suggestions sought on which engine to go for please. https://outerzone.co.uk/plan_details.asp?ID=5216 Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted December 26, 2022 Share Posted December 26, 2022 DLE 20cc,,,, Quote Link to comment Share on other sites More sharing options...
Dale Bradly Posted December 26, 2022 Share Posted December 26, 2022 Big fan here of the Stinger range. Either the 15 or 20cc will fly this. I have the 20cc in a broadly similar plane and it can be a hooligan 🙂 , the 15 would be fine too. Note however that they use a rear mounted carb (most gassers do), unlike most glows. The narrow fuse of the Kaos might make for a tight fit with regards to throttle and choke pushrods in the tank bay. Not insurmountable. Experience has told me to steer clear of the NGH and Evolution (if still available) ranges. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted December 26, 2022 Share Posted December 26, 2022 Just bear in mind noise if you are on a noise sensitive site, you'll need a decent canister silencer. Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted December 26, 2022 Share Posted December 26, 2022 Stinger 20 goes well, powerful and easy to use. DLE seems more........ refined; but is, if course a bit more expensive. Both are quite noisy so you may need to spend quite a lot on an effective muffler. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted December 27, 2022 Share Posted December 27, 2022 So Dle are more expensive in England ?, with customs it's the other way around here. Quote Link to comment Share on other sites More sharing options...
cymaz Posted December 27, 2022 Share Posted December 27, 2022 I got both a Stinger 20 and a DLE 20 RE The DLE went through the noise test with just a couple of pepper pot ends and silicone tubes. The Stinger is far more harsh in tone, mine also uses a 1/4x32 plug. The DLE has the standard ( and much cheaper) CM 6. Out of the 2 ...I should have bought a second DLE 20. Just my preference, the Stinger is a strong reliable unit in fairness Quote Link to comment Share on other sites More sharing options...

Yeah, from a little to a lot. I have two 'Stingers' - both, I am slightly ashamed to admit, came from China and were half the price of a DLE....... good, reliable engines. Supplied muffler is useless though. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted December 27, 2022 Share Posted December 27, 2022 I have the older versions when a 15cc was 100€ and the 20cc 125€, my Dle's were both less than 250€ ( RA ) and the side exhaust 219€,,, Quote Link to comment Share on other sites More sharing options...
Graham Bowers Posted December 27, 2022 Author Share Posted December 27, 2022 Seems like a Stinger vs DLE shootout so far. Anybody tried / seen / heard any of the OS petrol offerings please? Quote Link to comment Share on other sites More sharing options...
cymaz Posted December 27, 2022 Share Posted December 27, 2022 Clubmate has an OS 22. His ignition seems very sensitive to voltage drop on the battery. OS 22. ~£359 DLE 20 se ~£259 Stinger 20 ~£220 parts availability and price is another thing to consider Quote Link to comment Share on other sites More sharing options...
Eric Robson Posted December 27, 2022 Share Posted December 27, 2022 I have 2 Stinger engines a 30cc twin and a 15cc rear exhaust single, both the new edition. The only downside is the noise, it does not effect me as I fly well away from populated areas, I haven't tried a decibel test as no-one in the club that I know of has a meter. I would think they would fail. I am very happy with the performance and overall running of these engines. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted December 27, 2022 Share Posted December 27, 2022 They are both noisy, one of my Dle 20cc RA, has the canister and another I have adapted two small stainless steel boat silencers which make them bearable,,, Quote Link to comment Share on other sites More sharing options...

OS 22. ~£359 DLE 20 se ~£259 Stinger 20 ~£220 parts availability and price is another thing to consider As I said earlier, I'm afraid I went Chinese for my Stinger and it was under £130, delivered. Took about 2 weeks to arrive, and I was happy to gamble on no after-sales for that price. Not sure about spare parts - I know they're available from China too. It sat on a shelf in my Pigeon Coop (workshop) for about 15 months, then started first spin of the starter...... Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted December 27, 2022 Share Posted December 27, 2022 The muffler was hanging off my 15cc petrol for a flight and I noticed no 'growth' in the noise at all...... 😞 I too fly in a pretty remote area so noise is not a huge concern.
