Went out with my new Raven 30 today... Amazing. Compared with the Hawk - well, there's just no comparing them. Equipped with Irvine 39/MP2 running on 10% nitro this is a rocket. Climb rate that leaves the 90 equipped Pmax behind and the head speed goes up while accending!!! I am so used to bogging while doing a power climbout that this was a total surprise. And the dial goes to 11 (that is 11 degrees pitch). This is the single most important upgrade to the Raven. Throw in the super fast and accurate CCPM system and it's a winner hands down... Hugh loops without any power loss... Just no stopping this thing. And the engine stays cooler than it did on the Hawk with a Maavrik muffler.
Only things left on the check list are moving to 85mm tail blades and upgrading to torque tube drive (the tail is touchy even with the delay set at 35% on the GY502).
Bear in mind that this setup is not suitable for the stock Hawk sport. It will simply not hold together under the stress.

Raven30/Irvine 39

Nir,

From your post, it seems the Irvine is one powerful engine. I tried a number of their 36H's a number of years ago and really liked their power and carburation. I just found that they did not last anywhere near as long as the OS's. Keep us informed once you get over 125 flights on it.

Hi Phil,
I am past the 80th flight (rough calculation) with the Irvine and still going strong. It will, however, need to make room for the 91 C-spec equipped big brothers...

Hi Nir,

As most all my OS32's lasted well into the 400 flight range - let me know the Irvine is doing when it gets into the 300 or so area. My Irvine's only got into the 125 - 150 flight area before somet5hing failed. If they have become longer lasting that would be great, as I loved everything else about them.

I have just finished a Raven 30 with the new OS37H / K&S tuned muffler and have also found it to be "balistic" using +11/-11. Pulling through everything like a sim.

I was wondering how your Irvine 39 has held up?

HI Phil,
I since converted the Raven to 50 with OS 50 Hyper - even more ballistic
The Irvines were fine but you just can't go wrong with longer boom/blades.

Whats involved with convertion my Hawk Sport to Raven, just the ccpm upgrade? Its got torquetube, aluminum SE side frames and servo frames, I ve got a OS32 with a MP2 and its good really good power. I have HS 5475 HB digital servos in there now, are those good for ccpm.

Thanks

Wedge,
It's a long list but the bottom line is - not worth the $$ converting. Better off with a new kit (with all the current upgrades). Do a search on this topic and you will find your answers.

I see Century sell a ccpm conversion for the Hawk, Falcon. It is $90 is it worth the money.

What I was really interested in was converting to ccpm, would it be benifical, if needed I could make my own mounts. Or is this not worth it.

wedge,

I agree with the others that it would be more benefical to just buy a new Raven. I, myself, converted my Hawk into a Raven and love the response.

If you opt to get the conversion kit, you'll still like the setup once you have done it.

I guess it depends if you are willing to spend for either the full kit or the conversion. In any case, good luck to you.

ya maybe I will leave the Hawk alone, I was planning on flying the hawk this year to learn all I can on that, then buying a Raven 50 at the end of the year for a winter project to fly next year. I ve only put one gallon so far throught the Hawk, so still lots to learn on it, and it flies very well the way it is.

I am on my second Hawk even though I have a Raven 50 put together at home just waiting. I figured that I'd rather crash the Hawk than the Raven so am still learning on the Hawk. Just getting into FF and doing some nice large FF figure 8s, managed to overcorrect and then not correct enough on SUnday and needed new blades, main shaft and some other spare I had but the boom was OK. Once I get proficient enough that I can do the figure 8s, some nose in hovering and general flying around I'll take out the Raven and break it in.

If you ain't crashing you ain't learning. Well, I know some folks don't crash as much as I do but I tend to push it and suffer the consequences. I "know" the routine I should be following but I keep wanting to try other stuff. For example, now that I'm starting FF, I figure it's about time for some stall turns and loops and I'll likely try those pretty soon even though I still have to work on nose-in hovering and increasing my control.

I view it like skiiing. I can take it easy and never fall or I can push my personal envelope and fall a few times.

The closer to edge you are, the more likely you'll crash, fall etc.

Oh and if you aren't on the edge you're taking up too much room

Yes thats true, I have not yet crashed and I hope I never do, I ve flown 1 gallon so far, and I can do FF figure 8's, 540 stall turns, loops, rolls, nose in hover, now learning to do inverted stuff, I was very close to crashing the other day, I mean really close, I recovered like 1' from the ground. I then landed after that, to calm the nervs. I am starting to want something that flies better, but the Hawk is plenty for now, I can still learn lots on it.
