Hey All, I was wondering what it would take to get a brushless set-up to reach the speeds of 80-90 mph ( a OS 25fx tweaked w/mousse can )) I have a half dozen or so smaller brushless set-ups, parkflyers, running 200-250 watts w/30 amp ESCs and 1000-2200 Mah 3s1ps, I know that I`m gonna need some bigger li-pos,ESCs and motors, I get alittle confused when crossing over the nitro specs ( rpm vs watts ) I pulled this off a website on a motor review, and the spit weighs in at 3-3.5 lbs.............Hyperion .25e Spitfire spinning a 10x10e APC prop on 4S 2200 20-30c lipo pack , with a 60 amp ESC. Whole setup works fantastic. Clocked the plane at 86 mph in a level pass against the wind with gear down. Vertical climbs are mind-numbing. Motor comes down a little hot because I'm riding it WOT at 40 amps, which is pushing the edge of the motor's recommended limits. I suggest using a slightly bigger prop on 3S or slightly smaller prop with a 4S setup like mine..............anyway I sure would like to do both Open-B and 2610 combat E-POWERED...I`ve talked to a few people about it, and they`re very concerned about a Li-Po fire, due to mid-airs. Hey thanks for all and any help.......oh yea also I should mention that they will WOT all the time ( 5 mins ) Well that`s how we do it with our SLIIIIIIIMERS [8D]

I would say those who are soooooooo sceptical about lipos have not used them. Not saying its 100% safe but they do not always blow. You have a higher risk of getting killed driving to the post office than flying a 100S set up flying at a million miles.

If you want speed the main issue is NOT your power set up. Even a brick can reach 800 mph if you tie it to a rocket. Your fuse is the main hurdle. So you want to go fast ... with what sort of plane? Aerobatic plane? Scale plane? Hotliner? Flying wing? You need to decide on that 1st. Also, how big a plane do you want?

My Micro Jet is doing 80 mph on a simple set up. I had a little pylon racing plane that was faster than then MJ with an even cheaper set up. So you need to decide on what plane first. Something like the P51 will need more power to get to 85 mph than a hotliner. But again, the P51 looks sharp.

The planes that I was wanting to convert are in 2610 Combat ( http://rccombat.com/index.asp ), which are WW II 12th scale fighters, ( plus or mnus 10% ). so they are scale streamlined to go fast, I thought with a full cowl ( usally partly open to non-exsitint on the nitro ones ) would be even better.The AUW averages 2.5-3.25 lbs., average WS 39-48 inches..Thanks for your help

Twisted - something like the AXI 2826/10 would be fast on 4S.
