Ok im hooked !!!!! this is going to be my 2nd heli and my first scaler!!!!

I went out yesterday and bought the Little Bird at Toys R Us and im ordering a Hawk Sport to put into it today !!!

I have read all I can find here on RR on this project but still have some questions

1) I plan on putting a os .46 in it what other parts will be needed to properly use this combo in the Little Bird? 46 will fit in the 32 mount right? 14 tooth pinion gear?

2) Can i use the stock Hawk boom or do i need a longer one?

3) Is a torq tube neccessary or will the wire drive do the job?

4) Do I need to use metal side frames or are the stock frames fine?

5) I have the carbon mount by century for the T/R servo (the one that bolts to the frame under the boom) and am using the stock wire control rod with the guides on the boom. Will this set up fit inside the boom?

6) What blades should I use? (Looking for inexspensive ones please)

After looking at the various pics i see that some have the mechanics set way high up in the fuselage and some are real close to the floor !!!
I like the way the lower setup gives more servo clearence but i see that if done that way that the boom will be slightly out of wack !!!! With the higher set up the boom is straight but servo clearence suffers greatly !!!!

What do you recommend high or low and why?

Now all that being said and asked keep in mind that my flying skill are minimal and im not looking for performance all i want to do is fly and have fun !!!! I want to keep the cost down as much as possible so I dont want to buy anything that isnt neccessary or vital to completing the project succesfuly!!!

I dont know where else to find info on this conversion besides RR and have read every thing here on the subject(many times) so any links to info and pics else where will be greatly appreciated !!!

Thanks, Max

DiZeaZed and I are going to work on the gearing. We are pretty sure at this point that a change in gear for this combo won't be needed as you are going to be looking at 12 lbs+-.

2) Can i use the stock Hawk boom or do i need a longer one?

Right now, it looks like the stock one will work fine.


3) Is a torq tube neccessary or will the wire drive do the job?

I would use the torque tube.

4) Do I need to use metal side frames or are the stock frames fine?

We are planning on using the stock frames, but plan to move up to metal or even CF lower frames. If for no other reason than to get the fuel tank under the mast (CG).

5) I have the carbon mount by century for the T/R servo (the one that bolts to the frame under the boom) and am using the stock wire control rod with the guides on the boom. Will this set up fit inside the boom?


In a word, no. Use the stock location.

6) What blades should I use? (Looking for inexspensive ones please)

We're still looking, but looking for woodies around 560-570. This should load the bigger engine with the added weight sufficiently and give the added lift needed.


BTW, DiZeaZed's main frames are up high in the frame and there is no problem with the tailboom. Also changed the Hawk to eCCPM to get the added clearance needed for the mechanics to sit high (see DiZeaZed's Gallery) and get the proper alignment on the tail.

Jldesign hooked me up with this link

http://flyingtigersrc.com/littlebird.htm

That link provides a wealth of information as well as many awsome pics

Id love to be able to keep as much of the forward cockpit section as he did (80%) but im not so sure of the way he did the servo relocation
Take a look at it and let me know what you all think about it please

Sure looks alot cleaner for a scale model (he didnt need to cut the top front area at all)

What do you guys think of the tail setup? I like his design but question the durability of it from the longevity stand point !!! Id like to do it but feel it wont be durable enough to last without causing stress fractures at some point down the road !

Also ive reviewd DiZeaZeds design of the eCCPM many times over and am contemplating doing the same with mine but want to make sure its the thing to do once he has tested and refined it a bit !!!!

Keep me posted and if you have any links to other sites on this project please let me know !!!

I'm sure there's a trade off there, but it seems like an awful lot of over engineering to get there. You get a weight loss by losing the servo frames and gain some by keeping the cockpit. Personally, I like doing away with the cockpit more. It keeps more weight up to the front and moves the CG forward on what is going to be a VERY tail heavy bird (the metal or CF frames will help as well). Besides, we are going to 'tint' the heli's windows to make it look more scale in flight.

AS far as the setup that DiZeaZed has designed, even on the intitial setup (design 1), it flew quite well, and the upgraded parts should only make things better. Remember that these flights were done with the mechanics only, so there was no extra weight so that will also help to make this heli more "subtle" in the air, to say nothing of the mods since then and some messing around with the Tx.

Max, if you are interested I have my 21st Century Hughes 500 for sale. It is already finished, all one has to do is install his electronics and motor and go fly. Am using the old electrics for another project. The mechanics are Hawk Sport. Pics in my gallery. Oh yeah, the asking price is $250 shipped in US............Dave

55crownvic,

Smoking deal but I love to Build !!!!

Did you alter the servo placement to get clearence up front ?

Max, I actually cut the part of the boom, that is molded in at the back of the fuse,away from the fuse and reattached it at a slight angle upwards to get more room for the servos and also for appearance sake. I didnt want my boom to have that "tilted up" look. There is a lot of work to do to these 21st. Century fuses to get them to look right and fit right. But afterall these were not designed as RC helis, only toys........Dave
