Just came back from the maiden this morning. This plane is a gentle giant, far more gentle than the initial impression of being a big, intimidating airplane. With 1/2 flaps landings, this thing floats in almost like a sailplane. Landed on the grass both times to make sure it didn't run off the end of the runway. But man, it's a power hog. Twin 5000mah, 6s Gens Ace got sucked down to 3.76v/cell with timer set for 4 minutes.

Or did they?

Congrats!

4min take off to taxi back with short taxi on 5200 and add just about a minute on 6200. The 5200 are 620-640g/ ea and the 6200 are 760g/ ea. The 10oz difference total is a little noticeable. The 6200 do have a little better punch. I just bought new same 6200 and the newer ones are 70g/ ea heavier, Going to have to decide if I use them or not. I also have 5800 RT's that are 765g/ ea and fit better since they are long/ narrow.

4min 'in the throttle' time for me on the HRB 6000 50c's and had plenty left in the tank; will probably try to push towards 5 since I had so much left. It all does depend on how your flight goes, but I really like the way the HRB's perform per dollar. The 2 pack is 150 bucks on amazon.

I've been wanting to give the new Liperior 5000 75C a try, but they've been out of stock. Great price though, and they have tested out at a true 35C (175A).

I use them in my F-22 and it shrugs off the extra weight. They're too heavy for my taste in the F-18C.

Congratulations on a successful maiden. If you go to the Roaring Tops, I would not recommend the 6250 35C for these 2 inrunners, not a high enough discharge rate (although great for the outrunners), however if you are taking off of asphalt, which I know you are, then it shouldn't be that much of a problem (just a few more meters of runway) and the additional 1250 mah per battery would help the flight time (and they only weigh 790 g). You could use the RT 5500 70C (same weight), but I think the HRB 6000 50C-100C burst (weight at 824 g) would be better for a little more capacity and just as much power for the inrunners, and at a cost of only $75 per battery. Just my 2 cents.
I've checked out the HRBs at Amazon.ca but they are expensive and not too much choice. Amazon.com tells me to go to .ca. I'll check again and take a closer look at the RT. I was going to get more of the ChinaHobbyLine but bigger, but their website was so glitchy, they would accept my money. I'm not spending that kind of effort to find out why I can't give them money.

Can you get these on your Amazon? I got a dozen of the 3700 4S for my Bronco, Tigercat, P-38 and various other warbirds and love them. I want to try their 6000 6S.

Originally posted by crxmanpat View PostMy experience with the 6250 35C's are quite the opposite. I use either those or 5800's in all of my Freewing jets, and they love them. They are a true 20C (so capable of 125A sustained on the 6250's) and provide plenty of power. In fact, the T-33 is the first single EDF jet that I can get 4 minutes of spirited flying and still have 25% left upon landing. I fly off asphalt as well, but they work great on unimproved surfaces as well. I still want to try the new Liperior Pro's as the 5000 weighs the same as the 6250 and would be a drop in fit without worrying about CG. Those test out at a true 35C sustained.Hugh "Wildman" Wiedman

Hugh, I use R/T 5000/5500, Jetwerx 6000 and HRB 6000 for the majority of my 80/90mm EDF models but just bought a single R/T 6250 to try. Put it in the T-33 first and wow she had noticeably more thrust AND I came down with more than my usual 14% ! Could have been that all my packs are old and/or this one was shiny new. I never break my packs in and forgot to see what my IR meter gave me as a true C rating but I was impressed, will buy a few more when the time comes.
Don't have a single 6 cell pack (out of my active 17) that began life better than 34C according to my Giles IR meter.

Actually I'd assume that running the wires around the ring is probably more effective but would love if someone with more knowledge on the topic could confirm, maybe Gringotuerto ?

On another topic and OMG AND LOL!!!!
Several posts back I was detailing how I was having nose gear hangs during retract and how I “fixed” the problem. WWEEELLLL - The problem returned this morning. Only one out of 5 flights did it retract.
TURNS OUT - Not jamming against wind-blown doors!!!
IT WAS A NUTTY SERVO! Always worked on the ground. Stopped working in the air.
Tested it out this evening after installing a new retract servo. The problem is FIXED! Soooo happy / was about to pull my hair out.
