Here are some pictures of the subject plane. Infact this is the second one, I own, the first one was totalled at RCPA and immideately the next one was ordered.
The model is powered by am OS 108 2 stroke engine mounted inverted and performs flawless
Some more
flyingboxcar you are getting very good pictures, you should disable that date time stamp on your camera. but its a personal preference thing.
Adrenaline does some very nice harrier and inverted harrier, gr8 looking plane Kapitaan.
Bravo Captain!! The flight looks fantastic...
would love to join you folks in Chennai.. but have too clock so many hours in my logbook before I can have eyeball with veterans like you!
SLS,
All photos are taken by another flyer at the field who is also a good photographer. Will any way suggest him about the D/T stamp. But if you ask me, that helps you (may be few years later to rememebr the ocassion ;-))
Gusty,
This craft, also excells in all knife edge manouvers. No coupling, and holds the KE easy peasy with just a bit of rudder
Ujju,
Come over to Chennai, you are always welcome
what about KE Loops esp in the lower 1/2 ? coz i am looking at 120 still available
Gusty, honestly have not tried KE loops yet, had planned to do that today, but was having fun with the 40 size tiger so did not even take out the Adrenaline out of the car.
Should try that next Sunday.
The model is said to be designed for 90 size 2T, but I dread to say that you would have to add atleast a pound of lead with a 90 engine. I have roughly 130g of weight up in the cowl with the OS 108 and Dubro metal mounts.
read that on other forums on the cg issue of 90, actually adere 120 is good balance, is it 2 piece wing ? i have booked 120
PS
did some insane flying today
Yes both 90 and 120 are two piece wing. On the 120 I would presume, that due to design the CG issue would still persist, but I have not seen or assembeled one so may be I am unaware.
A 120 is waiting to be started here in Chennai, the person was not very happy with the minor niggles.
is he jettisoning ?
Lovely plane it looks. Would do nice pattern, I am sure with the nice long tail moment.
90 size seems to be just the right size plane. I was also looking out for the 120 but dropped the idea since it wouldnt accomodate a gas engine, without a lot of modifications
With its tail heavy design, 120 might need a 200 Four stroke to balance properly - without the need of lead. WOuld be awesome to fit in a gas engine on it somehow !
Gusty,
Do not know if he is, will ask him when he is at the field next

you stole my thought , just in the morning i ordered a MT 35 , for the adrenaline 120 or the SU 26(Probably), i have seen the Adre 90 fly, the nose is slightly small for a gas engine , i guess it will be a shade wide, some cutting job may be required, . long fuse wiggly tail, how much of expo ON THE RUDDER for a steady hover ?
your thoughts FBC
I have a major problem with the thrust line hence Hovers are howevers. Many of you may know that this is my second Adrenaline 90 after I pranged my first one. The model as it comes from factory has the horizontal and vertical centrelines drawn on the firewall. My first one had the centrelines correct and assuming it to be right second time I just measured and drilled holes for the mount. And what did I have severe left thrust!!!!.
After the maiden I had to mount 3/32 ply pads under the left engine bearers and also do other mods to keep the prop centred and then there is lot of right rudder and aileron trim to negate the issues emanating from the crooked engine thrust line.
I know the only way is to open up and redo the engine mounting. Maybe I would once I am inclined to.
And I re learned the lesson again, do not beleive what comes from factory. If the workers who make these were as careful as you they would be buying these models and not you.
And upto 30-35% negative (Futuab) Expo is my standard on any aerobatic models to start with
Capt. Did u ever consider putting a DLE 20 in the nose of the Adrenaline 90? Do u think it would be possible? Waiting for the servos and then will have to consider which engine............ ASP 90 or DLE 20.
What servos are u using for the bird?
Doc
Flying doc,
I do not posess a DLE 20 hence never considered putting it on this one. If you read the posts above some disussion did happen on these lines and people said that to put in a petrol engine you would have to cut away most of the cowl. And then if you have the model you would realize how tight the space is in the fuse. After installing the tank there is hardly space left for a battery pack, leave alone the ignition module and battery pack for ignition.
On servo front, I have used Hitec 5625 MG on ailerons and elevator, 5645 MG on Rudder and 5485 HB on throttle
Hi Capt,
I went through a lot of ur posts for the Adrenaline on other forums and in one of the forums I found that a talk of shifting the CG to 150 mm was going on. At what position have you set the CG at? We would be mounting the engine today and hopefully take off for the first time tomorrow.
Waiting to hear from you.
Safe landings
Doc
mine is per the manual
Thanks Capt. That is what I'll do. The Adrenaline does not take off tomorrow as our field would be overgrown with grass and takeoff and Landing would be difficult. Will be flying the high wing trainers.
Hope u have a good day of flying.
Doc
The Adrenaline is dead! :(
Long live the Adrenaline ;D
What Happened manish? How? Sad to hear that.
Plain simple
Dead stick, tried that tad bit extra glide to get back in to the wind, turning in from base to final did the trick, the model dipped the nose after a gentle stall, not sufficient time/distance left between concrete tarmac and model. The pretty stiff wind down the runway also added to the issue, where before the model would have again acheived flying speed, and I would have pulled it back to horizontal, that tough concrete surface rose up to meet the models nose.
Result a badly broken airframe, a mildly shattered engine and sheepish looking flyer :giggle:

"Ewe", hope it didn't get your "goat" when it "ram"med into the ground!
But jokes asides, it is sad to lose an airplane. So the adrenaline rush will be now subdued?
Until the next "inter"val.
Cheers Manish!
Ouch.............. That hurt me so so much. Really sorry. Hope the adrenaline rises again... for the 3rd time.
Doc
The next time it rises, you should christen her as "Phoenix".
All the best Manish!
This Sunday I am flying mine, she has undergone a lot of mod, asp 120 ar change from 120FS, which was short on thrust, STD servos changed to hitec mg hi torque pull pull on the rudder, turnigy 648 mg on the elev and aileron, some nose weight, she should be good to go, manish/ doc could you scan and send me the manual, I misplaced mine and not able go find one on the net.
Having had two of them, me think I would move on to something else. Not an adrenaline
@wingco will send soft copy tomorrow.
