Thunder Tiger Raptors 30-90 - Imperio > R-30 Crash Kit blade balance way off

Ok, I'm trying to do things right and do a spanwise balance of a set of R30 blades. As the set with the kit were pretty close, I went ahead and glued the blade grips before checking balance. I'm using a Kyosho balancer. I balance, mark the CG and compare. One blade is 5mm different than the other. I can see what the problem is: The blades have the clear heat shrink and I can see that one of the weights is about 1mm farther out toward the tip than the other. I cut trim Monokote and more Monokote and more Monokote to try to get the 'lighter' blade to have the same CG as the 'heavy', but it's going to take a whole boatload of trim to get it there. A 110mm by 125mm piece is stil not enough to get it in balance. Even if I do get it to balance, the weight of that blade has increased significantly.

Ok, so what should I do? Get them to balance and not worry about the weight difference between the two? I don't have a gram scale, so I wouldn't be able to measure that, anyway. Trash the blades? Buy another set and hope I get blades that balance closer to one another?

As I'm at the hovering stage, I'd like to stay with the woodies for a while before moving up to the composites.

I had a pair like that. The TT woods seem to be a crap shoot. Thats when I bought a pair of World Model glass blades for about $25. They were not balanced either but they were much better and no glueing of the blade grips. Do a search for "World Model" on this site.

Hi Kevin,

Actually there are three things to get right when you're balancing blades according to Curtis. He doesn't own a blade balancer and describes his method in his book of questions and answers.

1) Weight of each blade should be within 2 grams
2) Span CG within 2 mm
3) Chord CG within 1mm (.5 mm for flexible blades like woodies)

You can get a high quality gram scale on eBay for around $50 - good investment!

Sell your balancer and use the Curtis method with a straight edge. Let me know if you need more info on this...

I use Red Duct tape from Home Depot. I find the lighter blade and cut a piece of tape that added to that blade, would make it weigh as much as the heavy blade. Then I find the CG on the heavy blade, and transfer that location to the light blade (where I *want* the CG to be on the light blade). I then put the tape on the light blade in wherever spot makes the CG be at that point. No problem. I would think Monokote is too light. I mean, the stuff is *designed* to be light.

typical tt blades!!!!!!!!!!!!!!

your experience w/the crash kit is a mirror image of the kits themselves and the r 60's are worse yet/about 2/3 of the blades are so far off on cg that the correction requires disturbingly larges amounts of correction such that the same applies to the spanwise and is aggravated by the fact that you must add all the weight at the cg for the spanwise/ive built at least 7 r30's and 5 r60's and most always disturbed by the lack of quality in the blade covering and the non-existent cg matching!/your method of balance is fine and buying an ohaus scale is way off the deep end!/b4 u do that you would do better to just buy moderately priced sab frp-fiberglass or carbon fiber mains/for a really low cost good alternative i suggest the aerotech woodies marketed by century helicopter products/they seem to have somehow maintained the high quality of years passed both in cg matching and blade covering integrity/i am probably one of the few in my circle who still regularly and tediously balances woodies mostly for training and virgin kits!/dont dispare u r not alone, your experiences are seen all over/tt had started to carry white covering in their kit blades in the r-30/seemed 2b a good move/dont know why they stopped/my lhs has stopped carrying raptor 30 and 60 stock woodies and opted to replace them w/the aforementioned aerotechs on my recommendation and noting the same problems u have noted over a very long period time!/someone eventually will take the time to bx up and send tt a dozen or so of these crappy blades and tell them ccccccccc look what you have been doing all over the country!/until then i suggest u flyem and dont buyem any more!!!

KyoshoKamper,
There is a key on your keyboard marked with a ".". You should try it sometime. It makes a world of difference.

Kevin,
Here is a quick little proceedure for balancing woodies:
http://68.43.117.149/raptor/blades/balance.html
With the 30 size woodies, I usually just do a quick "teeter" balance and bolt them on.

Kyoshokamper,
Your posts are just about the most difficult to read. Also, when "I" read a post, much credability is lost when it's typed in ubonics or with bad puntuation. Don't get me wrong, I'm not trying to bash you.
I must agree with your observations on Aerotech blades. The 30 size blades are very well matched however, I have found that the 60 size blades are not matched so well.

go ahead and spit it out!!!!!! Michigan PI!

Now that's just great, a self-proclaimed TT representative makes what I and most would consider a racial insult. Insulting remarks about eubonics and consequential apologies are even more of an insult. What does that have to do with helicoptors? If I were a representative, I would probably worry more about TT's credibility than some guys diction, and typing skills. I wonder what TT would think of your post?! Just fix the TT OEM blade problems and stay off my case. Why dont you just call me the "N" word and be done with it. I can smell your thoughts from here. I was only trying to help while sitting on my two tots and typing between screams. That is very unprofessional of you and your apology is not accepted. Don't bother answering this post because I won't.

kyoshokamper,

What is racial about asking for someone to write more clearly? When I read your post, it never entered my mind about your race, and I had the same concerns. I don't think that Jeff considered your race either.

Clear communications via the written word are important. I could care less about the race of the person who wrote it.

We are all human, we need to not be concerned about the color of someone's skin. Your response shows that you do.

Even if someone is racial, lets try not to let it get to us. I know it may be hard sometimes, but we must try our best at all times.

Tim.

Well, at least he got you to use punctuation and mixed case this time. I know he did not mean it as a racial insult since no one knows or cares or wants to know what race you are. You probably set him off by publically insulting his company "Typical TT blades." I have used many sets of TT blades and I think they are fine. No, they are not as good as $90 blades, but I choose to spend $25 on them and balance them myself. I don't gripe when they arrive out of balance because everyone knows or should know that you have to balance them.

There is nothing racial about ubonics and/or poor or lazy diction. Forgive me if I have insulted you, it was definitely not my intention. I have no clue to your race nor do I really care. I could care less about yours or anyone’s race, ethnicity, national origin, educational background, religious beliefs, income bracket, make and model of vehicle they chose to drive, or the toothpaste they use. And, unlike you, I do not attack others in public forum.

I had actually thought you were experienced, well educated, and by previous posts that I have read here, I thought you were quite articulate. You have clearly proven me wrong with your explosive comeback and grappling for the race card. If you want to troll for bigots and racists, try posting to some other forum, not here. Sorry pal, this isn't the place for it.

The point I was aiming for, if I wasn't clear enough, was that the post earlier in this thread for you was very difficult to read. Nothing racial was intended nor implied.

RC Helicopters don't see race, ethnicity, national origin, educational background, religious beliefs, etc. That's the great thing about a hobby like ours, it knows no barriers, we are all brothers in this hobby regardless. Doctors, Lawyers, Sanitation Workers, Fry Cook, it doesn't matter, we are all on a level playing field on the flight line... black, white, yellow, brown, it doesn't matter. English, French, American, Russian, Chinese, African, Canadian, Japanese, it doesn’t matter.

I see alot of hate in your post, and that is sad, especially in the times that we're in.

To get back to OEM Wood blades...
Sure, TT blades may not be the best, but they definitely aren't the worst. The Kyosho wood blades are the worst I have ever seen. Warped, unmatched CG's and weights, and that sticker that is impossible to remove.

"that sticker that is impossible to remove"

That was a good one, Jeff. I had (emphasis on HAD) a Nexus, and I had that sticker problem. I used rubbing alcohol, my fingernail, etc and nothing worked short of just getting an Xacto knife and cutting the film off of it

Usually when I come across a post w/ lots of misspelling, bad punctuation, etc, I just skip reading them. I don't think there was any racial profiling going on there (racial profiling in heli's??). We all should be thankful that we have helpful people taking there time helping people out, either w/ their heli's or their bad spelling/basic punctuation skills.

My 2 cents.

"....most would consider a racial insult."

I sure didn't. Did MP know your racial background when he posted his response? I didn't until I read your angry post. Chill-out.

They're balanced

Ok, thanks for the sidetrack guys. Back to the matter at hand. I have the blades balanced now thanks to the suggestions above. It's not pretty, but they balance spanwise and teeter totter style. Also, as tape is on both blades instead of one as originally balanced, the weight difference between the two has been reduced.

Thanks again to all for your help. Peace.

EBONICS!! please who do you think you are talking to!

The world is full of well educated people with serious social problems, who refuse even in the face of their peers to admit wronging another. The word ubonics is inherently racial and refers to people of African decent usually in a derrogatory way. But you know that! You and your little buddies may pretend not to know the concept of trigger words but I know better than that. That is one of the oldest tricks in the book, the muted understatement. You quietly mention off the cuff a racially connected trigger word and cleverly mix it in with what appears to be ok among guys type conversation. Well it didn't work here and you have been found out. Condemned by your own words! Did you think I would not notice? Did you think I would not respond in kind. Try going to work next week and spouting your mouth off like that about ubonics or more correctly ebonics and see how long they keep you around. Thunder Tiger/ACE is a multinational corporation that likely might have serious concerns about a so called representative with a propensity for trigger talk and racial slurs. You might be hiding now, but rest assure I see you clearly. Semiarticulate's comments are an example of truely generic criticism with absolutely no trigger words or racial connotations.
Darkstar, tittelba, rsilvers and robb dont waste your time trying to defend this moron. He knows exactly what he did. I must say respectively to you that your view of Michigan PI's post is not the important one, mine is. I didnt have to think 1 second before I knew where this guy was coming from and I'm not alone. I would bet that none of you would dare mixing trigger words like that in general conversation and expect to do well in life. I could give you a long list of common trigger words that when defined or taken alone mean nothing really but that are guaranteed to get you hurt, killed, fired, rejected, divorced, thrown ot of court, etc. But, I will not lower myself to Michigan PI's level. Some things are just not PC because smart alecs have been trying that for far too long and it is no longer considered cute or smart. Michigan PI you have my sympathy. You are not as coy or as sneaky and cunning as you thought you were. I SEE YOU CLEARLY NOW!

So, the weather here is sucky today. Wish I had some fuel to fly my new 50. I got about 6 flights in saturday and it rocks.

By the way, after balancing my brand new 50's blades chordwise, spanwise, even weight and everyotherwise all I had to do was add a piece of tracking tape to one bladetip, heck need that anyway. These were the most perfect set of blades I've ever used. Way to go Ace.
