Good point. Just an FYI to all those that don't know and you probably already all do. The 15-25 size have a max wieght rate on the airframe of 7lbs. I have a set in a plane that is 6.5lbs with battery and they are holding up fine.

The electrics have to be the small size, I have heard that the 120 size are way too big.

I have TamJets mini retracts on my 8lb Starfires, I have two, and these minis are severe overkill. A bad landing will just rip them right out. I also have Tam's struts attached.

Bottom line, I think Bob Vincent is on the right track, whatever retracts that will fit, but wire struts. Just bend them back after a bad landing.

Flyboytha1 will build this plane with the best stuff, but based on his past achievements, the cost will be $2500 when finished.

To each his own.

I'm using Tam's retracts with wires for now. When the struts are available, I'll get them! They come with the matching aluminum wheels

I have Tam's retracts in a 10.5lb plane and they work great. The wire struts are no good off grass though at that weight and bend back on take off every time. Only got worse as time went on and got softer from bending back and forth. Once I put the trailing links on it seems like the units themselves can handle any weight you throw at them.

... I posted a bunch of pictures of the CMPro T-45 I got last week here, just the plane out of the box for now.

Seems nicely made & relatively lightweight compared to other CMPro stuff

I have the fan, motor (Neu) & esc combo, the Springair 602's seem to fit just fine.

Hi Herb,
What Neu motor are you using and how many cells?

You guys got me wrong,Tam mini's are great, with struts even better. However there are other other things to consider.

1. waiting time

If you are in a hurry, and want to fly this bird in two weeks or less, I have a spare set of TamJet minis with struts that I will sell at twice the normal price. LOL.... E-Flights you can get tomorrow.

Wow, this pic from Herb's blog shows it is quite a bit bigger than the Sapac Hawk. Makes me feel like now I can justify getting it even though I have the Sapac Hawk.

Wow guys opening the box it really is VERY nice!! I like CMP stuff already as I have their 120 sized Spit converted to electric but this kit is really nice! The paint and pre-printed covering is sharp! it is an eye pleaser for sure. It's just big enough to be a really nice 90mm size plane. Should have a b it better wing loading than the SAPAC too.

I have the 10-15's in a 6.5lb L-39. A little springy but holding up fine. The 15-25 are the same units, just thicker wire.

Also, I've had good luck with EPF Hobby's DSR46T units. I upgraded to the metal side plates as well. They have a new set with trailing link struts & metal sides. They will be strong enough for this plane if it is in the 8-9lb range.

I opened the box, just had to do it. The below quote is good advice based on what I saw and felt. The main wing is thin, built up and covered with CMP thick covering. It will resist wrinkles, but there are several hollow points built into the wood to lighten it up.

Some of you guys could actually over build it into a flying brick. This baby needs to be kept light. It should be built like a heavy foamy. I'm not even sure about the Midi Pro with an ARC motor.

I gotta jump over and see what Herb is doing, for some reason the 90mm setup looks to be too big. OK I jumped over, Herb has it taped together so from basics it looks like the 90mm Midi will fit perfect, the ducts fit.

Note Herb's warning about the wings, very thin and very small. A hard landing might push the gear all the way through. There are some negatives. This plane has to be built light...
