*Hi Steve and All,

Richard sold me his EXI T-Rex 250 helicopter, Scorpion Motor and Jeti
speed controler for helicopters with programing board. The T-Rex-250 is
smaller than a piccolo and yes Kicks butt! Head speed is 4000 RPM.

This video was shot here in Tehachapi with Richard flying the Little
T-Rex 250 the yellow helicopter below in the picture about 5 day ago.

**Here is a video of Richard flying his T-Rex 250 with carbon 205MM blade.

**

Richard flying T Rex 250 11 8 2009 (4 min 53 sec)

**In the pictures below the helicopter names are as follows Back to
front T-Rex 500, T-Rex 450, and the little one is a T-Rex 250.*

*.

.

.

The little T-Rex 250 has a Carbon frame and a all metal head. They Run
about $54.00 from Hobby King. The head speed of the blades on the T-rex
250 is 4000 RPM. Bothe of the Larger helicopters T-Rex 450 and T-Rex 500
both have a head speed of 2400 RPM.

The Larger two helicopter are ready to fly. I have been flying both of
then on a regular basis. Here is the current video of Richard Chandler
flying 3D Helicopter maneuvers with all three helicopters.

Re: Speed 400

Hi Ed.

All of these suggestions are in runners for and a geared 2.3 -1
reduction drive to be included. They are to equal or better a Speed 400
7.2 volt about 90-110 watts or better.

This first one is a inrunner and over kill. 2X the power as a 400 (180
watts) (400 is 90-110 watts). This does have the same shaft size and
mounting holes I am pretty sure are the same too. Sam weight as a speed
400 though. at 63 grams.
http://hobbycity.com/hobbycity/store...hless_Inrunner

This one is nice with the right shaft size and mounting holes I believe.
and weighs less than the above. It is a real hot motor though. you
might end up with a 6X5 prop.
http://hobbycity.com/hobbycity/store...hless_Inrunner

This is the best choice so far. The right shaft size (2.3 mm) and
mounting holes and the weight is less than a speed 400
http://hobbycity.com/hobbycity/store...ess_Motor_(FIN)

This si the same as above but much faster and would work with the 7X6
prop or 6X5 may be.
http://hobbycity.com/hobbycity/store...s_Motor_(FIN)_

This would work for a 8X6 I think right shaft and mounting. Less weight
than a 400

I hope this helps.

Mine was long enough ago that nimh's were'nt available yet. It used a mfa
" rocket " 400 3:1 on 8 600ae nicads with a 7x7 apc prop. It was
suprisingly fast and could do very large loops. Might have to do another, I still
have the plans.

Re: Speed 400 7.2v Equivalent Brushless - Hacker B - 20

Hilaunch@aol.com — Sun, 15 Nov 2009 18:23:00 GMT

Ed,

I use the Hacker B - 20 12 L with a 4:1 gear box. It can be propped
to run well on 2 or three cells between 100 - 220 watts. It works very
well in the E Blaster and some foam models weighing up to 25 oz or so. I
usually set it up for a 20 - 25 amp draw for take off and then about 1/3
throttle is enough for sustained flight..

Although the initial investment is a bit more than a speed 400, it
will last a lifetime. I have several, but the oldest is at least 5 years old
and is used several times a week. In the Blaster I use a 900 Mah 2 or 3
cell LiPo depending on the thermal activity and my mood? 3 cells gets me to
600 feet in about 15 seconds, 2 cells takes 25 or so, but the lighter
weight (14 oz) is better for light thermals.

Here is the link to Aero-Model and the B-20 page.

Hi;
What Brushless Inrunner would anyone suggest to replace a Speed 400
7.2 V with a 3.2:1 gear box & 7X6SF Prop?
Also using a 3 cell A123 1000 mah pack & 20A ESC, which gives me
12.73 amps & 114 watts?

TIA
