That looks so awesome, but, I doubt if it would help me. Need to check to see if I can afford one. Now for the so called retarded people, some of lthem are a lot smarter than I am. It is great when you have one that can tell you when the plane is not doing what it is supposed to do. I have lost count of how many I have helped in CL and RC. DOC Holliday

Nice work Brad. It's no simple task to develop and bring a design to production and satisfy the masses.
Looks like you already have some satisfied customers.
Keep up the great work.

Heck, John, I think we had words once... More than a decade ago. HAHAHAHHA!!! We are getting old brutha!!!

I do remember my first designs. A lot of people said, "why don't you fly so and so's design?" Maybe my designs sucked back then. I did not care. I like the T-Rex... it is superior in every way to anything I have ever done.

We be bruthas, no matter what! Yes, I am gettin old...so maybe we had one pissin contest. I caint member! Water under an old bridge. I like yer bird too! I will have one before the dust settles.

It is too big for any engine that I currently have in my arsnel or junk barrel. I would, however like to fly one some day. Right now I do not think I could hold it as my hand is still really tender.

Yes, obviously the typical foam wing suspended bellcrank is NOT original.

Coming up with a way to re-create such a thing in an ARF with a two piece wing is altogether another story. Especially if the goals were:

-make sure the the bellcrank was completely installed in the inboard wing and ready to go

-AND the USER does the final gluing of the mount.

I want the USER to glue in his own bellcrank. So, I came up with this stack ply/ply washer system that simulates the old foam wing suspension. No easy task actually.

No doubt well thought out, Brad. The best bellcrank installation of the ARF lot for sure, one does it oneself. I'm liking it, especially the 4 stroker. It looks industrial!

I am waiting for a flight report using a Supertigre G51.

We, Phil Spillman and Willis Swindell, went out to fly Jim Welch’s T-Rex with a ST 51 today. As you can see by Phil's smile we liked the flights. There are now three new T-Rex’s ready to be built. Here is a before and after picture of mine your choice which is the before and which is the after.

Actually I put it together for another club member in exchange for a T-Rex ARC. Only one flight, was a bit fast 4.9 sec on 63 foot lines, need to drop the take off RPM. Also turned inside tighter than outside, easily corrected trim issues thanks to adjustable intake and controls. Sometimes you just know when you have a good one, this thing is going to be a killer.

Bradley Walker · « **Reply #112 on:** November 01, 2009, 06:49:51 PM »

You will find you need about 1/8 to 3/16 down elevator at neutral flap to be equal. I find this true with nearly every design I have flown.

Well, if the TR works with the side mounted Saito and the inverted PA and pipe (both in Tulsa) then we have demonstrated both extremes of cg and mounting flexibility and functionality at one field. My job is done here.

I highly recommend anyone using the Saito copy Bob.

Thanks for the info Bob, sure is tempting to do another with my Saito 62.The total trimming on my st51 version was a tweek of the outboard wing with the heat gun,exackly what brad said (1/8 down on the elevator) and moving the tank down 1/8 and flys perfectly.I guess i'll have to go plural and do another with the Saito 62 since I love my 4 strokes...thanks Jimmy

Bob Branch E-Rex from the Amped up forum.

Bradley Walker · « **Reply #115 on:** November 12, 2009, 10:08:32 AM »

Amazing finish.

john e. holliday · « **Reply #116 on:** November 12, 2009, 03:30:51 PM »

That looks absolutely gorgeous. Not too gawdy and reminds mu of some of the real planes of the 40's. Did I say I love the paint scheme.

Brad and John

thank you,

Very cool and unique scheme! Definitely one of a kind.

Scott Hartford · « **Reply #119 on:** November 13, 2009, 01:35:51 PM »

I do believe I have a spare Saito that needs a new home! I think this plane looks neat and I will be getting one! Good job Brad!

Wasn't the pilot one of the Village People? YYYYYYYYYYYYYYYYMMMMMMMCCCCA!

Actually , if you are a hockey fan, he is a dead ringer for the Red Wing's Todd Bertuzzi. My wife noticed it right away.... oh, she is a hockey fan.
