Welcome to the Forum iGGiE,

I have flown several Pro38 motors (I did L1 and L2 on Pro38) and love them........ As far as a true comparison, I think they are both pretty close in price........ Pro38 is easier to use but Aerotech will provide you with more motor choices per case (ie an Aerotech 39/360 case has more motor that a Pro38 4 grain case)

Overall, I would say go with Pro38 for you L1, think about Aerotech later to give you more choices....

Iggie...Welcome to The Rocketry Forum!!!

That said , I have both and would make a suggestion. If you can fit a 38-29mm adapter in your model and it's not too heavy, eg:less than 4 lbs...you could fly it on Aerotech 29mm H128W's. the reloads are fast and loud, very cool and most of all, cheap! $12.50 for a reload, they are about a dollar more than a G64 for twice the propellant and about$5-15 cheaper than Aerotech or Pro38 38mm reloads. You can build quite a few HPR rockets that can fly on this load...I have at least six myself. Of course, you would need the 29mm 180/240 hardware, but it's a good investment.

Just a thought.

Chilly answered the question...I just bought a half dozen or so H128's from Ross at Magnum Rockets at the $12.50 price...they are starting to appear at many vendors and the price is about average. My son wanted a G64 and F40...at$9.95 for the F40, I had a hard time buying it, when for a couple bucks more we could have flown an H128...and the G64 was definitely out. We wound up with a F40W and H128W...and got to fly the H this last weekend.

The combo of Dr Rocket 29/180-240 casing set with one set of closures is a good buy at $69.95...saving you even more money. Carl #### shockwaveriderz ##### Well-Known Member Carl is correct....those H128W are almost a steal at$12.50....when compared to FG prices....

Thats why I'm working on doing my L1 right now.....A Dr.Rocket 29/180 motor and a H128W is even in my financial range...!

I was gonna certify on an H128 and Ross was SOLD OUT. :kill: No harm done though...you know the story on Sunday's wind and someone here on my side of Columbus is letting me use his H165 Redline. So life is good. #### aksarben10 ##### Well-Known Member For me availablity is what counted the most when I made the hardware choice. I went with the Pro-38 system not because of price but because Giant Leap always has them on hand. I think the price argument can go either way. I may still get some AT hardware someday, but I am sort of waiting to see where the whole regulation business goes before I invest in another system. Plus job aspects as of late do not allow me to spend much money. So here I sit content with my Pro-38 casings. I finished the set with the last sale that they had. Scott #### n3tjm ##### Papa Elf Pro38's are expensive, especially with the smaller loads. The Case is the cheap part. The 2 grain Pro38 load is about the same price as a 3 grain Aerotech 38mm load. At one of my recent launches, I wanted to fly my EZI, I had two motor choices to buy, a Pro38 2 Grain H154, or a Aerotech I357-10T. Both loads were the same price. I would of gon with the I357, but nobody had a 360 case I could borrow, so I went with the H. The prices get more reasonable with the large loads. #### shockwaveriderz ##### Well-Known Member I did a comparative fianancial analysis between a Pro 38 2 grain H153 versus several AT H reloads with DR.Rocket 29-180 motor.. Prices are from MagnumRocketry.. Motor pro38 p38-2g$29.50
Dr rocket 29-180 $48.50 Motor cost$29.50 $48.50 Reload cost pro38 H153 AT H128/238 1$26.50 ($56.00)$12.50 ($61.00) 2$26.50 ($82.50)$12.50 ($73.50) 3$26.50 ($109.00)$12.50 ($86.00) 4$26.50 ($135.50)$12.50 ($98.50) As you can see from the above chart, only at the initial motor/reload purchase are you saving money. Starting with the 2nd and then subsequent reload purchases, by the time you have purchased that 4th engine, you are actually saving$37... these savings do not include the delay charges requirements of the motors...

If you replaced the single 29-180 motor with the combo 29-180/240 at $69.95 , you would still be saving money by the end of the 3rd engine purchased. This would allow you to then use the H210R motor at$22.50....still less per engine charge than the H153.... SO by the 3rd engine purchase you could have :1 motor/reload or 2 motor/3 reloads to choose from
