I found out the hard way that my new Red Arrow BAE Hawk does't have enough power I need help to find out what I should do. The motor , fan and batteries are the same as other Hawk fliers but my first flight was impossible to controland ended in a crash.The airplane is a Century Jet model with a 60 inch wingspan. Weight is 10.5 pounds. Fan is an Aeronaut TP4000 5 inch diam with 5 blades. Motor is a Neu 1910-1.5 1200 watt claimed to produce 10 pounds of thrust with 40 volts. 680 RPM per volt. Battery pack is 10c 6000mah Thunder Power., and I'm using a Jeti 90 ESC. Take off was sluggish and once in the air it wallowed and was barely flying.The hawk has an Eagle Tree on board recorder and the recorder during preflight was operating at 3000 RPM, 3 amps and 41 volts at low throttle. RPM maxed at 10500 at 33 volts and 43 amps. My understanding from EagIe Tree was that the optical sensor I installed would read half of the real RPM. I tested the plane after the crash and the RPM, current and voltage were about the same as before flight. At 680 RPM per volt, it should have been 22500RPM. I used a hand held tac and measured the RPM at 23300 after factoring for 5 blades instead of the 4 set on the tac. If I double the RPM recorded by the Eagle Tree, i would have 21000 RPM. I measured the thrust using a fishscale for a ground pull of 3 pounds. These things just don't add up. The voltage, curent and RPM are close to expected to produce good thrust for flying as well as others have with this setup. The thrust measurements and flight performance look like they agree to very poor flight performance. Any ideas? Any suggestions to resolve the coflicting data?

The Pitesti cup was supposed to take place today but typically slow organisation meant that there was no flying for most of the day. Eventually the F5F pilots had two flights each and some test flying was permitted inbetween. The F5D guys had minimal flying too. Hopefully tomorrow there will be lots of flying with F5B starting at 8am.
Here's a few pictures to give a flavour of the day.

Finally got out and maidened my mini RCDisc (as it's now known - damn lawyers ) on a damp, overcast, cold evening with the light quickly fading. Initially I tried a 7x3.5 prop on the GWS brushless 15T motor and together with a heli 25amp ESC and 1200mAh Lipo it flew not very much like the big floaty 3' disc. Did someone say fast??!!!
After some quick passes and general 'getting a feel for it' I decided to bring it in. The trouble was that the field was chock full of cow pats so there's no way I was going to let it touch the ground and it wasn't going to easily float into my hand like its bigger sister. This mini disc was coming in hot. It was like a moment from a USAF carrier operations training video showing F16's being snatched out of the air. The main thing is I got it home excrement free....well apart from maybe on my shoes - well its only cow poo.
Next day I switched to an 8x4 prop with the idea being that I could slow it down with high pitch and prop hang...but I'm still giving it full throttle as a hangover from many a practiced geared 350c launch. Bad idea.
It was quite a shock & awe moment as it shot over to the other end of the field before I'd finished the throwing action. Had to make a severe hard turn to avoid the hedges and then it was back over to me in an instant....hard right to avoid my head....AAAGH tree!! throttle full, full elevator, scuff the top branches and finally I was off into the tupperware lid grey sky giving me just enough...Continue Reading

after many "tough" flights, the ExtremeFlight Edge 540 slab is once again re-incarnated and ready for flight duty..!

it has been broke in half i think 5 times now..it might be 6..has had at different times, a YS53, a YS63, and YS63fz, a Saito 72, and now, since the latest round of repairs and weighing in at over 6-1/2 lbs, a Saito .91 with a 15x4W mounted up and ready to go..!!

that freakin prop is lookin' mighty big on there..!!! I LOVE IT...am gonna try and get 'er back in da air this weekend..!

what none of the pics show, is that in my "fixins" on the plane, once or twice i might have forgot to check how straight things are, and it now has about a 20degree "hook" in the fuse behind the "canopy" section.it has been crooked for a while, and flies even better than it used to..!

i cannot recommend this plane enough..it has been the absolute hands-down winner for toughness for anything i have ever destroyed/flown..!

Chris has them in stock now at http://www.extremeflightrc.com and they are worth their weight in GOLD..!!

In my efforts to create spectacular crashes in G3 demo, I have come up with this:

no photoshop editting!
I blew off both main wings, the whole tail assembly, and the nose and main landing gears.

Nothing too special.
I just decided this could be my initial blog entry.

I am starting a hobby,and have always been interested in models and flying and thought this would be a good way to kill two birds with one stone,so to speak.If anyone has any ideas about what to start with,i wolud be gratefull.

Arrived at the hotel with all bags and models. One of the British team does not have his planes and the UK F5D team are all planes missing. We're hopeful that everything wil turn up in time for the World Champs, but as we are flying tomorrow in the Pitesti cup we don't think we'll all be flying tomorrow. We're in the Hotel Ambiance, which is about 2km from the flying field and serves beer and 'moonshine' till late!!
The town is surprisingly touristy - must find out a little more about the history before we leave.
I took a trip to the flying site late this afternoon but there was only a little activity.

Well it's not a good picture as it's getting dark here but as my new T-Rex 600 is as good as finished I had to bring out the gang for a little familiy reunion on the lawn....this time even the babies are out even if it's rather late...
