What are the best most reliable engines out today in the .15 and .35 range?  Would like to get into larger planes eventually but only have .049's at present. .....and can't afford expensive stuff. Whats the best older stuff to keep an eye out for in the .15-.35 range?

I've flown Thunder Tiger engines (.15 - .46) for years with good performance. The GP series are bushed; the Pro series are ball bearing engines --- they are middle of the road engines. New engines are expensive although you can find NIB engines on eBay --- just watch your bidding. Parts are also scarce, but this is becoming the case with many brands.

CL or R/C?

Pretty partial to Fox and Super Tigre. Fox being the more affordable.

OS .40FSR with the ringed piston. Vintage reliable power house. OS FP series is also reliable. Stay away from the OS FX series as they had a liner peeling issue.

Ya...I don't do ebay. Used to some before they instituted pay-pal only as a means of payment.
OS and Fox were a couple I was thinking of...not so sure about fox anymore from what I've read here.  No experience with those super tigre engines. Controline for awhile...already fly electric RC..but want to switch to nitro there too. Not fond of electric power and all of the unsolveable elec issues,not being an electronics whiz kid!

I don't understand your problem with Paypal.  Tie it to a cash back credit card and you make money or at least recover part of what you paid.  Paypal costs you nothing as a buyer.  

I do understand a reluctance to use ebay and I share that concern opting for other venues.  

I'm partial to Enya engines of all displacements.  I have bought many for less than ten dollars.  But that was in the past.  A quick check of Enya's on ebay just now leaves me wondering where all the good prices went.  But I did find this one for $9.99 with 2 days left, but no telling where it will end up.

Any way, good luck with your search.

One of my favorite engines is the Fox .15 X I have a couple of them , my biggest problem with them is the factory needle valve I have 2 that are flying right now and they both have RSM Super Tigre replica needle valves in them . I run Omege 10% nitro with 11% synthetic & 11% castor in them an 8x4 JXF prop and a good hot plug, run them in a wet 2 stroke plenty of power and very light weight

I'm with Bob. Seriously consider Enya, being one of the best finished engines out there. Prices might be getting up a little, but they're still competitive if not better than OS in price. Can't wear them out apart from serious abuse. Parts pretty much easy to find, still lots out there for sale. Start easy, run strong, don't have annoying needle issues or vibration problems. A little heavy would be my only negative.

I have 2 little Enya .09's and they are sweet little engines, one thing about the Enya .15 that I like is they are easy to put a muffler on very few of the Fox 15x's were sold with muffler lugs and if that's a requirement the Fox is out. I have an early Thunder Tiger .15 Enya clone with a muffler and its a nice little sport engine but parts are non existent , I also have an OS FP .15 & a Thunder Tiger .15 GP OS FP clone they run very nice have mufflers but are brutes I think they would have little issue flying a full size Flitestreak. Just some random thoughts rattling around in my head Lol TJ

I almost forgot, I have heard good things about the Brodak B-40 and the K&B .28, I have no experience with either but they might be a possibility in the future, both available new with good parts supply. TJ

The OS LA series are pretty under rated. The .25s we use for replacing the the Fox .35 stunt motor, run just as fast and are light. I would stay away from the smaller Thunder tigers, mine just can barely fly my planes, and have leaky cranks. The Pro BB series are great though. I have a couple LA .40 and a FP .40 with a peeled liner. The FP seems to still run well for some odd reason. Something to watch for if you buy any used OS. The early FSR and FP were iron pistons or rings and I would put them above Enya. I am not a Fox fan, but have a Fox .15 BB schnuerle that I am fond of. They come with a muffler that has a weak mounting system. Supertigers, Rossi, Taipan, Cox Conquest .15, are a good choice if you find a deal. I have had great luck lately at swap meets. There are no bidding wars like the _Bay. I have converted some car motors like Picco, Novarossi, that run great, but needed machining and drive plates/prop nut issues. Often these are $20. K&B I would put ahead of Fox I guess. For anything that you get, make sure they are not worn out or have cracked cases around the venturi and exh. port that would affect performance.

I have been a fan of the OS FP series of engines and to help them live longer with good reliable performance if you are going to use the available RC fuels with synthetic oil I would add castor oil to the fuel that way it with help you with corrosion on this engines. I have used Supertigre engines and they are very good also. But like I said I always added castor oil to the Cool Power 15% fuel with synthetic oil and after the last flight run it dry and add some after run engine oil.
