I just received this new CMP / CMpro T-45 arf, I have the CMP Spitfire and I like it ...

This thread in German or Italian

It is almost identical to the Hobbyking Hawk (also made by CMP or China Model Products : http://www.cmpairplane.com/ ) up to the paint

http://www.scaleflying.com/BAE-HAWK-...F-_p_2506.html

http://hobbyfly.de/en/rc-airplanes-1...40mm-6685.html

The Spit is a bit on the heavy side , but it seems now this Hawk is made relatively light(er) ...

The wing area on the T-45 is 24dm^2, so that makes the wing +33% larger in surface than the Sapac T-45.

Wingspan = 114 cm = 46 ''

Length = 122 cm = 49 ''

Wing area = 24 dm^2 = 372 sq in

Approximate scale 1:9

Est. weight rtf 7.2 - 8.0 lbs


CORRECT CG AFTER ONE YEAR OF FLYING:
ca. 110-115 mm from wing leading edge at root (see picture below)

Two friends at the field (Art and Don) already have one of these, they fly pretty well, the only changes on theirs was the fan and 3x good sized metal gear servos for the retracts.

I got the F/A-18 airframe only (with plastic wemo-copy fan & mechanical retracts).

Built it Thursday and Friday night and flew it twice today (Sunday) .

I use three metal gear Hitec HS81 servos for the retracts & moved the twin elevator servos under the fins.

The mech. retracts on mine seem to work fine so far, after patiently taking care of all the little mechanical adjustments.

I use a separate beefy 800Ah JR receiver battery.

I tossed the included BananaFan (cheap plastic WeMoTec copy) and used a WeMoTec Midi pro instead with a $19 HC B36-55 kv=1800 inrunner motor on 6S 3300's : https://www.rcgroups.com/forums/show...pp=100&page=13

These motors are now on their second year of flying in the Midi...

Mine weighs rtf on 6s 3000's (Turnigy 40C) 77.5 oz = 4.84 lbs = 2.20 kg , with ca. 1600W.

Guy H took these very nice inflight pictures with a Canon 7D. Thanks Guy

Just started my latest scratch build project, a 1/8-th scale MiG-21 MF (Fishbed J) EDF for a 101mm fan.

This thread in German

So far I managed to find some time to patiently cut out all the fuse formers and trial fit the fan ...

It will eventually be powered by a Neu 1515 motor in a 101mm fan on a 9S 4000 setup; depending on final weight (< 9 lbs) power will be in 3.0-3.5 kW range.

Inspiration for the MiG-21 project came from another avid edf-er JC (Bidule),

https://www.rcgroups.com/forums/show...1177686&pp=100

I found this particular plan on e-bay:

http://cgi.ebay.com/ws/eBayISAPI.dll...m=200453935022

The plan is nice and seems very well made ... will know more about the quality after the MiG has flown

Here's my latest project, a large FlyFly (or Fly Fly ) F-86 Sabre a la JePe Fast Foam,

http://www.flyflyhobby.com

http://www.jepe.org/FastFoam/sabre/sabre.htm

http://www.hobbytopgun.com/PC/F-86.htm

The model's wingspan is around 55.9 inches, the length around 55.5 inches.

The original Sabre had a wingspan of around 37 feet, so that gives the model a 1:7.9 scale.

I entirely glassed the foam airframe using multiple layers of 3/4 oz glass cloth & laminating epoxy.
Now it flies on a 90mm fan on 9S lipos (4000mAh 40C's) at ca. 2900 W.
Weight rtf is around 8.3 lbs, so it's rather lightweight for its size - but nevertheless still reasonably fast and jet-like.

Here are the original instructions. An inspiration on the surface prep was the Dutch Master JePe Fast Foam site: http://jepe.org/

The main motivation for the project was to have a nice lightweight F-86 Sabre in the 90mm fan range, suitable for some
moderate aerobatics.

I had one of the first kits when JePe came out with it. An easy build and a very fast flier, neutrally stable - just like the original ones according to an A-4 Marine test pilot I met one day at the field.

JePe carbon fan, Hacker B50 motor, Hacker Master 77 esc, a very nice setup.
