3w80xi... i took this excerpt from another post of mine....

27x10 Bolly wood and i was a little disappointed as i only got 5200 RPM tuned to fly... So i switched to a Menz 26x12 Ultra and got 6000 tuned to fly... I didnt bother with the 26x10 Menz i have, Its rips when im flying, very noisy..

According to the prop power calculator with the 27x10 i am only getting 5.37HP and 36 pounds of static thrust, and with the 26x12 i am producing 8.34 HP and about 47 pounds of thrust. This engine is rated at 8.5 HP so i guess the 26x12 is the prop to use?

Edit* I was noticing that the Evolution 80 has a 27x10 Mejzlick as their benchmark prop, swinging it 6400RPM, are evolution engines more pwoerful than 3w? Yet they are so unpopular in the areobatic/IMAC and 3D scene

da100L with re2's and a mejzlik 26/12 about 400' asl 6900rpm.

DLE 111 first run out of the box....28-10 Menz, stock mufflers, 5800 rpm at 7000 ASL....

RCGF "B" Line 50cc engine. First run out of the box, Vess 22A 7200 rpm.

YouTube- Broadcast Yourself.

DL 50, home made cannister exhaust (freon can)... fully broken in, Amsoil 80-1, JC Super Prop 23x7, 80 degrees at 15 foot above sea level, 7480 hot. Pulls 88 inch EF Yak around like toy. Engine/airframe belongs to buddy and we tached it together today. Nice and quiet setup except the lightweight cannister has a hard tin sound...(I like it)

DLE-55, 2 gal, castrol racing FD, 40:1, mejzlik 22x10, 7500rpm

Super08 · 12-07-2009, 10:21 AM

Is that on a pipe?

Those number are definitely inflated, or your tach is wrong.....I ve seen several dl setups none have come close to 7500 on a 22x10.... Hell at that rpm its producing 6.97 HP

stiffy · 12-16-2009, 08:27 PM

mejzlik 22x10@7500rpm, it's unbelievable, even for myself!

maybe I'll take some photos or video this weekend......

pe reivers · 12-17-2009, 09:04 AM

6.3 hp
Must be the Castrol racing oil

with magic muffler.
A good tuned pipe might do it though.

Super08 · 12-17-2009, 09:09 AM

How about a mislabled prop?

pe reivers · 12-18-2009, 05:21 PM

Not with Mejzlik!

stiffy · 12-19-2009, 10:14 AM

guys, this prop maybe really mislabled.

the actual pitch is 8in I think (22x8 @ 7500rpm draw 14kg thrust is typical)

see video:

AHP · 12-19-2009, 10:39 AM

Now that's how you backup your claims! That's impressive, even if the prop is mislabled. The fastest I've ever seen a DA 50 turn a 22x8 on the stock muffler was 7250 (one of my own).

Super08 · 12-19-2009, 11:44 PM

Either way it is running very good. Nicely done.
