Thanks for the reply! Any advice on the build, weight to balance, flight characteristics? I have a DLE 55 and will use a pitts-style muffler.

Hi there, I havent flown it yet, but C of G came in just about right with my Z62 and an 800ml tank. I have ordered a new cowl after a bad cut out, and will be raising the sentre line of the engine by 10mm. There are a couple of videos of it flying on you tube,some electric some gas, I have heard some stories about weak undercarraige on the medium size version but not the 62cc. Will be flying her this saturday and report back.

The firewall looked a bit weak to me, have re-enforced it, and upgreaded the closed loop cables.

On the look out for a heavier duty tailwheel, and have ordered this pilot to replace the 'modern' pilot that came with it.

That ungodly muffler is a Damn shame. Jtec and Slimline make a pits style muffler for the G-62.

Thanks for the reply. You might look at the Slimline muffler before cutting your new cowl. Please keep me informed as to your progress.

Well, it had its first flight at the weekend, just caught the tail end of it on camera, but the feedback is as follows:

CG was perfect, spot on as per manual.
Even using reccomended throws, waaay over controlled, apart from rudder, going to leave the reccomended throws as high rates and half of them for low.
Waaaay over powered, it would fly well (but not balace well) with a 45cc.
Landing gear seems strong enough no problems so far, was worried based on reviews of smaller versions.
Looks and sounds fantastic in the air.
Doesnt want to slow down, very slippery on landing ( we used a 100m runway in the video ) and strong 15kmph headwind and 24x8 couldnt slow it down. Might try reducing the pitch.
The huge 24" prop looked amazing, loads of clearance and will try to get the largest, shallowest prop the ZG62 can swing.
Looking forward to getting it back up in the air this weekend.

I tried to get a Pitts muffler, 2-3 months waiting, so new cowl will sit in shed untill then, I have also ordered 1/4 scale cockpit panel and proper pilot.
I ended up with 125mm dubro vintage wheels, did the job very well. Must bind up the tail wheel to get her to brake a bit.

heres the clip (very short)

Graham,

Thanks for the info. I am looking forward to starting mine this winter. Will follow your advice. Please do wait for the muffler. I believe that Seagull messed up showing the stock G-62 muffler in their manual. Really messes up the appearance. I will use a 55cc with a pitts muffler and 8 inches of pitch. Likely will move the c/g forward a touch along with reduced throws.

Your flying field is beautiful. You live in one of the most scenic countries on the planet.

Please keep posting your progress!

Ominous weather for a Maiden flight! Checked out your videos....and went to your website. Is the DH 88 Comet still flying? What was the problem with it?

All the best,
Chris

Hi there, the Comet is hanging up in the Garage, it is in one piece but very difficult to fly largely due to its wing shape. The pointed tips induce tip stall at anything lass than running speed, in fact the end of that landing was the start of a tip stall and it was really travelling at that. I am building a YT International (ESM / Kondor) Tigercat at the moment that should do a bit better, lots of wing, huge tail plane and tricycle gear, should be fast too, but easy to land, the Comet just isnt. Its a beautiful plane, went to see the original in England, but way to hard to fly (for me).

I seem to be attracted to fast red planes............

DH-88 Comet
Denight Special
Cosmic Wind (Little Toni)
Sparrowhawk

I have a 45cc gilmore now but havent flown it yet.

Here's some well made Pitts mufflers, It doesn't take them long to get one made up for you.

Hey Guys, Sparrowhawk fitted with proper panel, pilot, ( still waiting on muffler ) and extreme envelope test flight this evening by top pilot from our club, Ger Kilbey.  Small mishap on landing, reported too little elevator authourity on low speeds so add about 15% to elevator, aileron, and 20% to rudder throws in manual.   Awesome plane, just watch and see what it can do, it is not sped up. Excuse Irish accents in video!

Hello Graham, can I ask a question about the Sparrow Hawk kit. Did the kit include the wheels?

Hi there, no, it didnt include wheels, I have since switched to Dubro 5" Vintage wheels, but now replacing whole wire undercarraige arrangement with Robart forked sprung struts after two landings punched the wheel pants through the skin of the wing, sheeting the area below the pants with very thin ply.

Hi there,

the struts I have ordered are these:
http://www.robart.com/products/58-di...5-14-wheel-max

so they can fit the Dubro Vintage Wheels.

I will post the pics of the installation, and by the way, guess what arrived today in the post!

My slimline Pitts muffler!

Tru-Turn, here we come

That is for the large 84" Sparrow Hawk with the G-62 (or equivalent)?

Correct. It is in reference to the 62cc version. I pulled the box out of storage and measured the cowl opening. If you do a review, can you send it to me?
