Good morning, I am experiencing sudden stopping problems in flight on my OS 95AX engine. After several times the problem is the candle, I used the OS n° 8 (it’s the one that comes with the engine) finally I put an old Enya n° 3 and there no more problems. Unfortunately these candles are no longer commecialisée! Which candle do you use?

Can you explain to me how we can assemble this type of these engines

deadly

I have recently got a plane with os gt33 and 18x8 is a hopeless propeller..i use a 20x12 and i get brilliant results and also it makes the engine quieter..you might want to calculate with a 12" pitch..bet the thrust measures will climb alot

Recently got myself one of these and I've been looking for what I need to power it, any tips? 😅

First like ever, 14 years later 😂 nice flying man

Wow!

Morcheeba and a flying video , what more could you ask for.

Hi how much nitro% in the fuel?

ชชชช😮😮😮😮😮😅😅 1:04 1:04 😮😮

I LIKE TO SEE RPM CLOSER TO MAX MAYBE I WOULD TRY 27 X 10 AND TURN 6600 ISH

Hi, Do you need any fuel pump to this engine or ...?

What brand of device are the two blue calculators?

Wil thanks for this nice video I just bought a Polaron ACDC and there are very few stuff in youtube about it. Your's is the best for sure. Do not care about strange comments I read about your work from one of the guys here. It's easy to criticize others work Why these people does not produce his own video about the matter?

I have a twin 31cc twin RCGF angina with 32 flights on it! It’s a nice engine!

I haven't broke my 65ax in yet,hope it runs better than my stubborn os55.yours seems to run good,just looking for dependable 60 size engine.

Excellent video

Is the spark Plug coming with the Motor?

what would the main reasons a engine like this would overheat?

So the os gt33 is way more powerful than this 40cc four stroke?

When I saw your test about the the OS GT33 putting 20.2 lbs of thrust and with those dle 30-35cc only have 17 lbs. And about 92 dB of noise. I'll go for the OS engines or the real DA engines.

prop?

What you use ro fix the calbe to the plane on this video?

9lb of thrust is equal to how many Hp or sp?

Where I can get this Prop nut?

Great Job how many HP ?

great presentation 55 lb of thrust = hp ???

Great presentation How many HP does it produce???

Moki engine?

Full throttle 17lbs of thrust per 7500 rpm

Music gave me a migraine

that test stand would not show true readings, the moment arms need to be equal in length.

How many comparison beetwen oil n gas, 1000ml gas : 25ml oil?

Any comments on the geartrain slop for these please?

I haven't finished my giant p40 warhawk yet but, i got a gt60 (as recommended) and my kit has the same fuel cell as seen in your video. Can you give me a guestimate on how long a full tank will last me??

Xoar has a 26 x 16 prop, do you believe this prop could be used on a Da 120?

Read your article, great review of this engine. I purchased one unused.

so where are the results ?,,, I run mine on an apc 14 x 8,,,

This is one syk airfield, beautiful area to fly planes.

43 Minutes wow! I'm just finishing building one, but there's no way I'd keep doing a 45 minute setup every time :) Building a 'jig' to transport each wing side together as one piece that slides into place all as one, while keeping the flying wires connected either to the fuselage or the wing section.

How do you connect the pixhawk flight controller to the gas engine???

Great presentation

15 x 6 prop

Does this have the same mounting footprint as the older style DA-100? Just wondering if I could swap out my 100 for this 120

mucha tonteria pero no se ve el empuje en nigun sitio

using 30X8 the engine creates more thrust? A have a 3W 110B2 and for my fly this propeller i for me and my fly in 3D plane, better than 28X10.
