Only hope to get close to that rpm is to go gas and stay at 3/4 throttle. Personally I do not do glow anymore at all. Either electric or gas. Saito has the fg11. Real nice little motor that power wise is similar to an OS .55. Of course sounds better being a 4 stroke gas. And no need to spend 20mins wiping down the plane when done flying.
Glow motors are easy to come by, hit a plane auction, ppl are offloading them for next to nothing like they are hot potatoes. Seeing 40-60 OS's go for like $5 each.
My own personal rule on fuel: Methanol for 60-size and below, gasoline for anything north of 60 size. Glow ignition all the way, though. The OS G5 glow plug ignites standard 87 octane gasoline with standard 2-cycle oil mixed in standard ratios and it does this with the same glow driver we've been using for decades; absolute wizardry went into that plug and they use it primarily in their GGT10 and GGT15 glow ignition, gasoline-fuelled two cycles. This plug is standard thread too, it should fit into p.much any glow engine that accepts normal plugs. Maybe I'll get one, throw it in my 46 AX and my Saito FA-45 MkII, see how they run on gasoline with a G5 plug in. Lessee...16:1 oil mix oughtta be good for those two, aye?
I.....don't feel like screwing around with, or carrying the weight of, CDI units,
especially with smaller engines where the CDI unit weighs a fourth as much as the engine it's firing off does. And given my transport situation this is the size range I'm working with. 40-60 size at most; I can't really transport a wing much larger than my NexSTAR's right now.
As for getting engines, I'll have to poke around more. I'm on the Glow Nation FB but those guys know what these things are worth and actually want them so prices there are kinda high from time to time. That being said i've nabbed some real steals from that bunch; an AP 061 for 50 bucks that came with a Cox Medallion 09 RC free and a Norvel 061 with a couple of rando tanks thrown in gratis for 70 bucks. Can't say no that! What I'm really after, however, is OS 4-cycles and Enya 4-cycles.
OS FS26 and FS40 Surpass engines make great powerplants for Flite Test planes
and for cars since OS themselves sold them with different cams, carbs, cranks for car use specifically. I'd absolutely love to throw an FS26C-X in my Slayer and my SC10GT but an OG sells for damn near a thousand bucks if it crosses eBay at all...but if I got my hands on a workable FS26 Surpass for a pittance at a swap meet I could just create a new FS26C for a fraction what an OG would cost. Same for FS40.
OS FS52, FS70, FS62V are the bees knees for my balsa plane ambitions. Reliable as a swiss watch, plenty powerful to fly any plane I can transport to and from the flyin' spot.
I want Enya 4-cycles for multi-engine applications. These things use two seperate cams, one for intake one for exhaust, and this quirk allows them to be re-timed for reverse rotation in about five minutes. I
think you can get cams for certain Saito engines that will allow them to run in reverse rotation(IIRC It's one of the cams from a twin that used the same cylinder), and if you want an OS FS to run backwards you're pretty much phoning up Crane or Comp or Lunati and asking them to custom-grind one for you since the OS twins are so much more bespoke than the Saito twins.
