Top Flite 1/7 P-51 Build

Aren't the #403's for 1/5 giant scale TopFlite planes?
If I order a set of the 306 retracts what else do I need?
A pump? Fittings?
Thanks,
Dan

Yep, I think your right. I just checked mine and there's no model number on them, but I think those are the ones I have. As for the accessories, robart sells a kit that includes everything. All you would need is that kit, a pump, and a servo. Electrics are much easier though, in my opinion.

Now that I have my Mustang back in the air and flying great! I need to replace the cheap Hobbyking retracts I have been using.
The plastic base cracked and finally broke today. So I need to replace the retracts before I can fly it again.
I went through 3/4 gallon of fuel today flying the Mustang. What a great flying plane! The Saito 120S is a great match for this airframe.
It sounds great and is fast. I have a nice big runway, so I usually take off and land without using flaps.
I'm looking at the eflite retracts.

I wonder which would be better?
Or can anyone suggest something a littler cheaper that would work well?

I have the same, got them at the Toledo show. Depending on completion of the Cub and Corsair, they should be going in this building season. What struts did you use and what adapters?

I have the Robart 653's left and right struts with the 3/8" adapter that came with the retracts. You have to pick what size you want when you order, and they are $5.00
If I remember correctly, I think I had to take 1/4" off of the top of the strut with my dremel tool. I also have the 3 1/4" robart wheels.
My retracts are the "normal" speed ones that are available. They also have a "fast" speed.
There is a selector switch on the retracts that you can set and adjust the delay feature.

Thse are the ones I have. The struts are currently hooked up to Robarts AIR in the P-51 wing, but will get pulled and installed with the Wingspan ones. I got the adapters, but dont remember what size they are, and since I wasnt sure what size the wire is for the strut I got the smaller one since I can always drill them out on my lathe if needed.

I've got my P-51 kit out and am scoping it out for a build. I also have the B-conversion kit for it.
One little 'touch' that I'd like to add is the scale prop that Top Flite used to offer, strictly for static display. Does anyone know what the part No. for this is, or if one is around anywhere? I know that they're not on TH any more.
Thanks,
Bob

They are very hard to find. the Part number is TOPQ7906 the cockpit kit is also very hard to find. The spinner is 4 inch, made of plastic, and there are reports of the spinner exploding in the air, taking the front of the plane with it. Google search for " P-51 on a diet" for your amusement.

Hi guys, Thanks for the info. The spinner is not a problem and I have a cockpit kit already. I just wanted to know if anyone had a line on the 4-blade display prop because it had the proper shape molded into it, i.e., the paddle blades and cuffs, etc. I finally dug up the part number myself (thanks for those who also did that for me) - it was right on the plans. For my plane, I'd probably use a plastic spinner for display and a DB Products Vortech for the actual flying spinner driving a 2-blade Xoar 16-6 prop.
Did anyone build a P-51 up with the Saito 125??? How did it fly? I'm curious of any pitfalls that I should watch out for (forward CG, etc). Other options will be a conversion to a B-model.
I'm reading some build threads now (including this one) but I'm just getting started.
Thanks for any advice you can give.

Thanks for that, crjdriver, I appreciate the link. The price is a little steep but the prop could make a hit at scale contests. Thanks for that link
Thanks for the insight acdii. I just checked the fit on the plans and the 125 is a perfect fit under the cowl. I'm going to have to start the break-in process.
Next question - I presume that no one is using the abs chin cowl or air scoop. I'm going with Fiberglass Specialties there, and will be using Lado retracts.
Comments???

I made a mold off the ABS cowl and made a fiberglass copy of it, half the weight. Will be much easier to fit around the 125 too. I have mine mounted in the ARF. It is a perfect fit, bolted right in place of the 100. There is some talk that the 115 has more power than the 125, and that the 100 and 125 are pretty close in power too, but wont know until next flying season. It was a balmy 2* this morning.

acdii, I was afraid to pull my own mold, but another friend already talked me into doing exactly what you describe. Your reply was the icing on the cake. Where I'm new with this, my thoughts are to mount the cowl (or scoop) and pour a plaster mold around it. Then wax the mold and use that to make the fiberglass part. I was going to lay in some 1/2 oz glass first, for smoothness, then go in and lay some thicker glass on top (i.e., inside) to build up the strength.
Would you mind giving me a snapshot of how you did yours, say, in 25 words or less?? Or point me to some resource that describes it???
Thanks,
Bob

I followed this guide. http://www.cstsales.com/tutorials/fiberglass_mold.pdf
For the backer I got foam display boards from Walmart and hot glued the cowl to it. I got the fiberglass from Autozone, both the mesh and mat, the PVA from O'rielly auto parts, the parting wax from SIG, and the rest of the stuff that is listed in that PDF from an online store. 6 coats of wax on the cowl is all you need, just give longer and longer times between each coat before rubbing it to a shine.

Thanks a lot... I think I'll scout around YouTube too, just to watch. I hadn't thought about pulling a fiberglass mold, but it makes sense. And, I could use the experience.
Where did you get that info about the Saito 125 in post 3046? I'd like to look in on that. I can't believe that the 125 would only have the power of a 100, but I suppose that it's possible.
Thanks,
Bob
