Ok guys, I have read that the Corona is capable of performing loops and rolls. I’ve been trying to figure out how. Take a loop for example; I’ve been playing about with it some. Since the machine is fixed pitch, when you pull up, it quickly looses all of its airspeed. So, I thought I would pose a few questions to those with more experience then me. Can these maneuvers be performed safely with a Corona? If so, what suggestions do you have for making them happen? I mean, like do you kill power during certain sections of the procedure or something else? How much of altitude do you loose? Will the machine burst into flames and fall to the ground like a ripe apple?

Thanks in advance,
Max

I have done two loops in two years. Both times freaked me out! It does loose altitude quick. You have to chop the throttle on the apex of the loop and pull back on the stick...once the nose is pointed down, then apply throttle to pull out of the loop. Sounds easy...but I thought it was going to smack the ground. Wait...I forgot....my first attempt...I DID smack into the ground. Sorry. But...I had some heavy assed cells mounted on my Corona. Now....with the lipos....Ithink it would do much better. I will wait for the summer to try some more crazy stuff.

I have never attempted a roll. I have done it with my Old Voyager and my old Hornet II....but not with the crona...yet!

I am just tickled taking out... flying it and bringing it back home in one piece!!!!

The Corona is capable of loops and rolls providing you give yourself enough height when you attempt them. The problem is that you loose a lot of headspeed and she will drop like a streamlined anvil. Ballistic Technologies is coming out with a collective pitch upgrade at the end on this month. I am anxious to see the reviews... It could open up a entire new world for the Corona.

I hope it is a better effort than the last collective pitch I saw for the Corona. I feel they need to do away with the Corona blades completely. No mater how much negative pitch you dial in...you will never fly inverted with thos plastic blades. I have been patiently been waiting for the better or upgraded collective pitch head for the corona.

I have to say....my Corona has taken a LOT of abuse and comes back for more. I love this little trouble free heli!!!

I dont think it is so much forward speed the concern but the verticle. I find you need to have some altitude some forward speed and as you are entering the loop-Nose in to the wind ,give it full throttle as you are pulling it over. Dont kill the power,you may not recover. Ive lost count how many loops ive done. Another thing, make sure your battery back is very secure before attempting to do wild maneuvers with the Corona.
Doing some fast Piros once then noticed my battery pack sticking about 8" out from my heli holding on by the battery connector.

Guys… What a great read. I sat laughing while reading about Dave smacking the ground, Chad’s comparison to a streamlined anvil and Darth’s reference to ejection power packs. Just plain awesome!

So, gleaning information for a loop:
#1 Prayer
#2 Tight battery pack and everything else.
#3 Lots of altitude
#4 Good forward speed.
#5 Full throttle over the top.
#6 Thanksgiving or a trip to the store?

Anything else?

I found a picture somewhere of the new Ballistic Tech. prototype collective upgrade and it had T-Rex plastic blades on it. I have heard that those blades are very durable... The Choppahedz version did utilize LMH blades, the Ballistic version with T-Rex blades might be the ticket :-)

That will be the ticket!!!! Now we are getting somewhere! I hope it proves to be durable and worth having. The Coppa Hedz....I just could not justify the $$ for something that would just marginally works.

Please post a link if you find one.

It looks like this new head is being tested with all sorts of blades...

I started the another thread. I am expecting a kit before end of the year. (preproduction) for beta testing. the full kit will be released in end of january timeframe. (final minor little tweaks are to be incorporated, but basic design is flyiing realy well) I flew the early prototype for several month as well, so I know it flies well. (and have video of it flying) I also had choppa cp kit, and it did not work.. in fact, choppa never even had video of it flying. Matt is going to have some video soon. (he is tweaking it out for 3D flying using 385mm blade) Matt is having early order pricing till Christmas, and you will save a bundle.

I will try answer any question you guys have on this. this is totally new design head usable with LMH blade as well as standard blade. trex blade works well for lightweight setup at higher head speed. for heavier setup, 385mm blade is necessary. I did most of my early testing with 335/325 trex as well as LMH 110 as well as 120 blade. 120 blade is bit too much unless you have good motor.

I think I got 1 loop out of my Corona. FF, a bit of back elevator to slight climb. Feed elevator slow and steady, full throttle all the way. Keep speed over the top of the loop, and bring it around. Sounds easy, making it happen is not. Never done a roll, but I hear a guy from Sweden has done one....
As far a a CP head... Made one, got the HS up, but the washouted undercambered blades made the mod mute. Going to a new, wooden blade would ruin its ruggedness (sp), so I went for a current CP heli..... A CP version of this heli with a semi sym blade of the same material mounted the same way would be sweet however....

I've looped and rolled corona, but with BT setup. it requires lower pitch setup and high head speed. (inside zlink also helps a lot) it also takes about 60-70'(I do them about 100'up) and full throttle. my acro LMH is 110 bladed setup that can turn near 3000 rpm and it can loop/roll lot quicker. (roll in 30' loss)

I've flown the CP with LMH blade a fair amount. it does everything CP is supposed to do, constant head speed, instant power, etc. being able to go to 0 pitch does help a lot for rolls and loops, and flies like CP heli. (stable but responsive) awesome lift and vertical power. (with appropriate powerplant) most of the LMH modified CP (including Choppa CP) that I've seen does not work well.(I had to modify choppa version extensively to make it work, and even then it was not great) Even motormike's had some issues with reliability. the new BTCP is a scratch design because modifying the existing design was not going to work well, and it is compromise at best. scratch design allowed us to use best of available design, material and geometry. this is fully 3D head design, and it is being 3d tested with CF 385 and 420s. we went through 3 different major revs before being satisfied with the design. 3D upgrade kit will includes thrust bearings, etc so it can handle the load.

Nylon 3D blade on CP setup is not really good either. it is too floppy and will still get damaged due to high blade speed. 3D require high head speed , and lots of power. no blade material can really survive this too well.

once you get full BTCP setup, you no longer have LMH corona. it is BT heli that can use corona blade. corona blade is great for transition learning. once crash occurrence goes down, it turns into 3D trainer, then into full 3D heli. flexibility, durability and flyability is a good thing.
