Kyosho motors - early 90s

[GoMachV]

I've heard it referenced as "endurance" also, but then how would you get to a 240e.... It's an oxymoron. An endurance 4 minute motor? I think something was lost in the translation long ago. It makes more sense if the "E" referenced a bushing "economy" version, because the numbers would already dictate endurance or not

This is only my speculation but I think it was a misprint in the 80's that we all believed

I think it even says Endurance in my '87 or something Tower Hobbies catalog. S for Speed, T for Torque, E for Endurance...SB for Speed & Ball-bearings, I believe. Maybe the 240E was an economy version of the 240 motor? I don't know. I *do* know that it stands for endurance with regards to the 600E.

Ive had several kyosho rc airplanes, geared and direct drive, and none of them ever came with a lemans motor. I do somewhat remember tower hobbies catalogs advertizing that some model did though,, cant remember which 1. My 240 E is built just like a typical mod motor, fully serviceable,, so its going to get bearings before being put to use.

You might be wrong about that...in that Tower Hobbies catalog ('86 or '87?) there were some Kyosho planes that had Le Mans motors...maybe the Valencia or Patricia motored gliders...I'll have to dig up that catalog again. Maybe one was electric, the other was nitro?

EDIT: Ahh yes, I just found a manual for the Kyosho Valencia 1800, which came with the Le Mans 240E motor.

There was also a Kyosho Etude and for some reason, I remember another with a name starting with "C"...damned if I can recall the name, though!

[rccars4sal]

Etude came with a geared 540, Cessna cardinal came with a direct 540,, except for the later version which was bigger and came geared. Stratus and soarus both came with direct 540s, and duet came with twin geared 540s. I had all those,, but not a valencia motor glider! Back in the day, the LHS guy said electric planes wouldnt work, because they were too heavy, and our altitude was too high. Every kyosho plane i had worked great, geared or direct.

[Coelacanth]

Apparently the Valencia flew great, too...but being a glider, you just powered up to altitude and glided it back down. I imagine it could be a lot of fun with today's brushless technology and long run-times, and was a slow-flying plane--in other words, great for beginners. I was really tempted to buy one back then...I wish I had, because they are quite rare and I think bring good money these days! (The Patricia was even more rare.)

Im a kyosho nut. Ive got 2 NIB airplanes from the nineties waiting to be built.... and 90% of my cars are kyosho.

Exactly. There had been other "E" type motors as the 600E and this again is an economy version. Actually all of the numbers are just showing Kyosho´s estimation of runtime range in seconds. This means any 240 should be a 4 minute motor, any 480 an 8 minute motor etc. Any additional letter as S (=speed), T (=torque), SB, etc. was just used as a quick reference for showing differences.

Someone was asking why Kyosho´s motors were not as popular at races as let´s say a Trinity motor. Actually most of the early Kyosho motors were of a high quality but all of the armatures were "just" machine wound so a full spec modified motor will have more power or more efficiency. But some motorbuilders were using Kyosho cans and armature blancs at some of their modified motors for some reason. This was at least Trinity and Revtech also I have seen motors from Checkpoint, GM-Racing and Drastic but not sure if those had been factory motors for their racing team or production.

Also as far as the suffix' go- it was said "240SB" meant speed and bearings- if that were the case the. The "240S" would have been bushing and it was in fact bearing. I think the problem started with translations.

[V12]

All of the early LeMans 540 size motors had ball bearings, beside the "E" motors. I´m not sure if the "B" means bearings in this case, as the original 240S still was available when the 240SB was released. I think the additional "B" maybe means second version instead of using a name like "240S2". Main difference to the 240S was a double wind armature where other early Kyosho motors were single wind. Another difference was the end bell where the usual plastic version was replaced with an aluminium endbell and fiberglass board for the brush holders.
But then they went with another strange name with the "480 Gold". The "gold" actually doesn´t tell very much about the motor
beside the golden colour. Maybe they didn´t want to use something like "480SC", 480TC" or "480T3" after their 480S and 480T.
Just an idea.

I remember reading somewhere that the "B" on the 240SB motor stood for brown. But once again something was probably lost in translation.

[Jirka]

B = Bronze?

[Coelacanth]

Maybe B = Better (or Best)...because the 240SB was better than the other 240 variants.

What would the WS in the Spa Motors stand for?
Well Sorted?

[GoMachV]

W= wet magnet?
