or, a couple 6S 3000's in parallel would fix it too..
Nope, no spinner. Haven't bought one just yet. I'll probably strap some lead to the front somewhere for now until my motrolfly comes in. I may switch ESC's as well, don't know if that will help or hurt me yet.

If I had more packs of a decent size I would absolutely go for huge batteries as a solution but everything I have is either 6S 4000 or 6S 5000.

there are some 6000mah turnigy nano techs.

I've been thinking about scoring one for this plane and the vyper.

managed to get my first flight in today before the sun went down. I ended up using stuff I had laying around ( 8611's, 10s 3800 TP packs) and was concerned at my all-up weight of 10lbs, 11ozs. well the damn think will practically fly at zero airspeed . incredably light on the wing even at this weight and very stable. the little bit of harrier I did was solid with no rock . ziltch coupling in KE with cg on the front of the tube. Since 10s Scorpion motor availability is limited right now I put a Himax 6320-250 in it which is pretty weak. actually has the best static thrust (18lbs) on a 21x8 Xoar fuel prop and putts around at 1/4 throttle. Put 900 mah's back after the 7 minute flight. Next week I am ordering a gear box for my Neu 1515 2y which should give it some serious snot and maybe drop back to TP 3300's. Looking forward to lunch tommorrow to try some stick stirring.

I did not know that the a123 packs are OK unregulated on the DLE ignitions. I remember it was NOT ok when I had a DL 50 a couple of years ago. I would have loved to use my 1100 a123 unregulated instead of a 2s lipo 1050 mah regulated. I have lots of wires on my gas 72.

I'm not flying this weekend since I'm working. I got the DLE 30 running today. It took a while and I had to squirt some gas in the carb a couple of times. I did have to adjust the low end needle a lot at our altitude but it starts pretty consistently now. I think I may have killed my HS 225MG throttle servo in the process. It locked up while I was transitioning the throttle on the ground. Mine may not maiden till next Tuesday.

Hi Joe,

Good to see you got it running.

I got my info from the tower site tech notes here.

http://www3.towerhobbies.com/cgi-bin...&P=SM&I=LXZZH1

and here. http://www.dle-engines.com/dleg0031.html Look at the tech data and recommended options towards the bottom.

All this was contrary to what I had been reading on the FG's DLE 30 thread so I called hobico engine support and they told me that the DLE ignitions are indeed rated for unregulated A123. YMMV.

They also have created a nice manual for the engine that actually has some useful information in it.

http://manuals.hobbico.com/dle/dleg0030-0031-manual.pdf

Don't know what happened with the manual included with the engine? It reminds me of my first airplane manual for the slow stick

Wow Hobbico has done a fantastic Job of making a manual for the DLE30 engine. I printed it out and will read it. I'm sure I will learn some new stuff since it's in great detail and this is only my 3rd RC gasoline engine.

I just saw that that pilot rc has the new DLE 170s. I can't wait to get one for the 119" Extra 330sc this winter.

Joe get the 119" now. Whats up on the "lil" 225mg servo failing ! Darn, I used the Aeroworks servo holder "lil wood box" for the standerd size servo, no cutting needed. So I put the larger standerd servo in. I used a Hitec 7966 MG servo, I have extra boxes if ya need one!!

Iím seriously considering the 330SC as my next airplane. Though Iíll admit, Iím a little apprehensive about stepping into this large of an airplane. My RC experience to dateÖ been flying helis for nearly 4 years and airplanes for 18 months. For the past 9 months, Iíve been learning 3D/high alpha-type flying on a couple of 3D foamy airplanes. Recently, I purchased a PA Extra MX, which is my first balsa airplane. My plan was to cut my teeth on the MX for a while prior to moving into a larger 3D airplane. However, Iím wondering if I should just go a head and buy the 330SC to compliment the MX. Just to give you an idea of where Iím at skill-wise, below are a couple of my recent videos, flying my Kalteisen 42 in. EPP Extra 260, which is a 2 lb. foamy. I also included a couple of my heli flying videosÖnot that my heli flying skills are necessarily relevant to being able to fly the 330SC with success. So, what do you think? You think I would be safe to buy and start flying the 330SC or should I hold off until I get more experience with the MX?

now, I haven't actually flown the 330sc yet, hopefully that will change tonight .

But...my experience with the larger 3DHS planes that I have flown, the 65" Vyper and 70" Slick, is that they are total and complete pussy cats. The reason people love these planes, besides the excellent customer service, is that they fly really really well. They have no bad habits and, given that you set it up as per 3DHS recommendations, there are no anomalies or problems to watch out for across a wide range of attitudes and airspeeds. This is not necessarily true of other brands/aircraft designs.

Additionally, the bigger the aircraft, the easier it is to fly. Obviously these planes are designed to handle some very extreme 3D maneuvers. But the thing that is often overlooked is that you don't have to fly them this way, and you can easily leave the plane on low rates until you are comfortable with it. The only problems that I have had with 3DHS planes fit into two categories: (1) I inadvertently goofed on a setup point and the airplane flew not so good. (2) The airplane flew so well that I became much too comfortable with it, and flew beyond my own abilities resulting in damage.

Hope this makes sense. I say go for it!

You would deffinatly have the skills to fly the 72" Extra 330sc.

It will smoth out the moves you are doing and encourage you to push things a little further.

I have been flying mine for a couple weeks and it just does not have a mean boan in its body

Be careful you'll be building the 103" version next

The only difference you will see moving up to something as large as the 72"SC from your Kalteisen (R.I.P. ) plane is a slower to react, much gentler airplane. The smaller ones are much quicker reacting, easier to overcontrol than the big ones. Little planes are also easier to get out of trouble on. Larger planes are super easy to fly, the only thing to watch out for I think is when you get into trouble. It will take a couple extra seconds for the airplane to react and 'come around' to what you want it to do. So you need to stay a couple mistakes high until you are used to that. Otherwise the bigger ones are awesome and fun to fly! Go for it.

If you are flying the MX then this will be a piece of cake. She is so gentle on low rates. Just get a good recommended set up and you will have no problem. I'm using the Motrolfly 4325-307 on 8s and she has gobs of power. Get her trimmed to your liking and she just glides in for landing.
