Hi Cambo and peter,

thanks for the info. i have made up my mind to go for the car engine. I ordered a .12 car engine with team associated clutch, hope i can get it mounted on the old crtuch properly. also, i remember someone mentioned of using music wire for the extended shaft, can i get the size of the music wire please?

many thanks.

hi guys,

i have found the post of the music wire dimension in this forum, it is 5/32, do correct me is i am wrong.

i am thinking of ordering new blades as my old ones are tatty, do u think i should go for the S2 10X5 or S2 13X0 blades? also, do i need to put in a longer boom version for the .12 car engine?

many thanks.

PS, Nostame: can i have a look at your video? if u still have them, please send them to [email protected] , plenty of space in that account. thanks.

Lawrence,

Yes 5/32 is correct or 4mm. You can also go for a 5mm shaft. You just need to drill the spur gear and the rotorhub to 5mm also.

Why not order a set of both blades ?
No you don't have to put on a longer boom because of the car engine !
Have you already ordered your engine ???? if not, I would get one with pullstart so you don't have to worrie about starting your engine.

If Notasme don't have the movies anymore, I do so let me know...

Hi Peter,

Thanks for your reply and info. I will get some 5/32 or 4mm ( or 5 mm) music wire from LHS. i would g ofor those with minimum modification , not because i am not good at drilling etc, but i am a student with limited tools in this flatshare. good idea, i might order a set for both and see which one flies better.
yes, i already ordered the car .12 and luckily, yes! i ordered one with a pull start , so that i can go flying without dragging the heavy battery and starter!

I am just a poor student who depends on bus as means of transportation and i have to drag all those field equipment+ heli+ radio + fuel on bus and walk

i have just checked my yahoomail and there is no movie yet, do u mind sending them to mi? as i jsut cant wait to see the machine flying



cheers

Lawrence

Lawrence,

Sorry I do not have the video any more.

If you go with the long blades you also need the longer tail boom. You may also want to go with the longer tail rotor blades (faster tail response).

The shorter main rotor blades will give you a higher head speed. The longer main blades will give more lift. You will need to
change your blade grips, this is something that you have to gage from the way you like it to fly.

One other thing is you will need a bigger fuel tank. The lager engine will use more fuel.

HI Nostame,

thank you for the info. I will take these points in view, meanshilw i am still waiting for the car engine to arrive for me to start the mod.
will keep u guys updates from time to time.

thanks

Lawrence

Lawrence,

I will send you the movies... my only problem is that there was a thunderstorm passing us a couple of days ago and it fried my computer at home.
First I replaced the powersupply which was totaly dead only to find out that my motherboard also got fried...

I will get you the movies one way or the other !

Was at the flyingfield yesterday and there was 6 helicopters there and 1 plane, all gasser except for mine
I sure got tempted to get a gasser, or should I try to convert my Corona again.. [sm=confused.gif]

Lawrence, what kind of engine did you order, and have you got it yet ?

//Peter

hi peter,

i ordered ofna force .12 car engine.it is still in the post somewhere, i cant wait to get it soon.

will keep u guys updates, thanks.

i have a very old kalt baron whisper electric heli flying this morning near the car park, it just cant get me the 'ummmph..' feel of the gasser although it flies jsut as good or even better than those screaming helis.

Hi All,
sorry about my absence for quite some time. really bad news about my car engine mod for lite machines. the order from tower hobbies actually didnt arrived to my address in UK. eventually they offered a refund. helpful people though.

then i was tied up with something else. i did put in a brushless and run on 3 cells lipo for the lmh but the flight time is too short. i think my motor kv is way too low at the moment.

i have another .12 car engine in the post now and hopefully i will get it this time and really start with the car engien coversion this time round.
will keep u posted. cheers

Peter_d, can u send me the movies? i havent got a chance to watch jsut yet. please email at [email protected]

cheers

Lawrence

Peter_d

Hey Lawrence !
Good to hear from you again... long time..

You did the same as I did, brushless 3sLipo. I get around 12 min, pretty hardflying with mine.
my setup is Orbit 15-14 with 3s2 4000mAh and when Im done the engine isn't even warm [8D]

Anyway I found the movies so I'll mail them to you..

Hi Peter_d,

thanks for the message and lovely video. i am still on progress( very slow) because i am distracted with another project. to turn the OLD Kalt Baron Whisper into brush less. i will keep u guy posted with further progress, currently only managed to mount the engine but still thinking of a way for throttle control as the servo link and carb is 90 degree away. any good idea?

Cheers and happy 2008!

You could either use a bellcrank or get a slide carb for the OS. I liked reading through this thread, thanks

Peter_d

Yeah, a bellcrank thats what I used on my first LMH/Apache with the Norvel 6 engine...

alteredguy

Peter d, I used a steel cable inside of a plastic sleeve for my throttle. It works very smooth.

hey alteredguy
could you fill me in on what motor you used and clutch set up??

Nino

Peter_d

Nino !

You can go with any .12 or .15 car engine. try to find one with a smaller exhaustpipe..
Also be sure you can attach a team associates clutch bell on it, it's the same tooth angle on their clutchbells and the main spurgear.
Good luck !

Lawrence !! any progress so far ? pics please

I am keeping an eye on some OS engines on ebay. I just got a hold of two LMH one RTF and the other one in pieces. It is going to be a good winter project to covert one of them to use a bigger engine.

Thanks for the info!!

Peter_d

Nino,

Keep the pics coming once you get an engine..

//Peter

alteredguy

NINO My engine setup came from a RC10 GT car. It is a OS 12 CV and I think the clutch is from Associated as Peter D. has stated. I did have to make a shaft to adapt the clutch to the engine. I would like to see what others have done for the clutch shaft. Also had to make a longer main rotor mast. The whole thing came out a little tail heavy so when I fly it , I keep breaking the stock tail gear housing. I do have one of the CHOPPER-1 gear boxes but I am going to make a drawing of it before I install it in case I can find someone to make another one. Like Peter D, I would like to see pics of what you do as well as anyone else who is doing this.

Peter_d

alteredguy,
About that engine, can't you use the engine, clutchshoes and clutchbell as it is ?

If I were you I would definitely get a beltdrive for the tail, It's a real money/time saver and you can use it with brets tail gear housing.

I attached my engine in front of the mainshaft to get a better CG. The design of the crutch is a little different from the original though
I'll post pic once I get home from work.

//Peter

Peter_d

Now I'm home
Here's how I attached my engine. I didn't have a pic. of it with the gasser mounted so I draw it up on a other picture

that looks nice

Peter_d

Thanks Jim,
Unfortunately I got this bird inverted in flight last summer and since it's a fixed pitch heli.. you can guess the rest,
let's just say it does not look that good any more.

That's why I made this one

Sorry of topic, back to mounting .12 engines..
