I use these on grass. When you land on grass (drag)/ pulls the wheels back thus the spring will give in that motion..

Out for a nice fly today. Video posted

Love the carrier type approaches this plane makes with the full flaps extended. I have it dialed in now. I'm on my second set of struts for this fat pig

What it's flight characteristics?
I had an EPO T-45 70mm and it flew like a trainer, and not so fast landings.

Greetings!

Really enjoy reading about everyone's build. Thinking about the T-45 to move into the jet era....what is that black switch on the side of the cockpit??

Hi guys,
Woo Hooo, I FINALLY broke down and purchased one of these beauties. I have had it on my "must order" list since they first came out. I even picked up one of those 'scale' cockpit kits and pilots from HK last year. Today was the last day of the Nitro sale so got it shipped for $170. I need to pick up the retracts next. Looks like HK has the Lander set. I'm going for a lighter 6s setup.
Now I finally have to finish up my HET F-20 build, also the HK Viper 70, oh yeah, the Dynam A-10 and Turbojet planes that are almost finished. Yeah, I have enough going to keep me busy, but this T-45 is at the top of my 'want to build' list.

I have read this whole thread now, so thanks for all the great insight and info about this model. Hope there are still some of you flying this plane. I kept putting it off due to some of the guys here calling it a heavy brick and very rough to fly/land. I think most of those were just over-loaded with large lipo loads though?
Well...gotta wait until next Thursday for delivery...plenty of time to prepare!
Happy flying,
Ken

She's heavy especially with RC Lander Fan and Retracts. I think 6S will dissapoint. I fly the 9S 5000mAh and performance is good. Would have gone with 10S but I couldn't balance CoG w/o adding weight to the tail...

Thanks for the reply Dave.
Looks like I have a lot more thinking to do about what setup to go with.
The only 90 size fan I currently have is a balanced Midi Pro fan. All my other EDFs are 64 and 70mm sizes.

I was afraid when I finally ordered one of these that it would end up being another $1,000 project. That's what happend with my E-Flite Dueces Wild twin. Parts started adding up until it was just shy of $1,000 when I maidened her. Money is a LOT tighter now, so hopefully I don't end up with buyers remorse with this EDF.

As for lipos, I do happen to have (2) 4000mAh 5s packs and (8) 4000mAh 4s packs. I fly my Dueces Wild and 70mm F-86 EDF on the 4s packs.

I'm keeping my eyes and ears open about setups for this plane. Gotta do it right, but might take awhile if it's going to cost a fortune.

Thanks again for your reply,
Ken

Thanks Dave,
Those are some of the items I have been considering.
Does this plane really need 10s to fly well? I was hoping more for the 6-8s range. I don't need to try and make it a rocket ship...I have plenty of those already. I just want a decent flying T-45...but not one I have to keep the throttle up at 80% or more just to stay level?!
Thanks again...more thinking to do.

I'm putting a Fan Jet in mine with a HET motor. My first one had a Wemo in it that I ran 12s 3300 packs. Unfortunately I can't give a report on it because I set the CG where the instructions indicated.

I'll run the Fan Jet on 8 or 9 and use 4000 mah packs.

Its not all that fast on 9-10S as you can see. Here is a short flyby of Maiden. I use 6S paks for my smaller foamy that are much lighter like RC Lander F-16 and 90MM Mirage. Access is very easy if you want to make changeds. Enjoy your build

Best to mention it now too. If you use the RC Lander Metal Retracts designed for this plane.... They BOUNCE badly. Here is a fix you should do before you land it....

YeeenHaaaaw,
My T-45 came on wednesday and it is perfect. Thankfully not a scratch or crack anywhere!
I am looking to go for a 8s setup, just not sure which motor yet. I have read this entire thread, now working my way through Herb's blog with his build.
Man, this is going to be a fun build but also going to take my time.
I'm just finishing up my Dynam TurboJet...an awsome kit. I am just having a TERRIBLE time trying to balance the two rotors. Everytime I think I have 'em balanced, I run them up and get that awful vibration and buzz sound

Good luck everyone...
Ken

How much throw are you using on your control surfaces? I may have missed the post if you already mentioned this. This tread is just becoming tooo long ;-)
Flaps are at 3/4 inch full and 3/8 inch mid. Aileron deflecection is 1/8 inch up both ailerons. I use the recommended throws. From memory about 3/8 in hi rate elevator and 3/8 hi rate aileron. Halved for low rates. I'm not sure how she will handle grass. Eats up alot of paved runway as it its....
