Testimonials- Where The Rubber Meets The Road
In less than a year the Giant Scale Aerobatic RC Industry has "taken notice" and praised the benefits Pro-Flow Canisters. This product fills a "niche" that has otherwise gone unnoticed. How could you not want to try Pro-Flow after reading through these "unsolicited" comments?
This Is What Satisfied Pro-Flow 3D Canisters Users Have To Say……………
From Father Don…………Dave (Sullivan) was doing Pop Tops before anyone knew what they were. When I first saw him do it, I just thought he was being cruel to his plane; my jaw dropped and I knew I had to meet this guy. Come to find out, he was flying a DA-170 on modified Canisters that really smoothed that engine out and made it run like no other DA-170 I had seen. Well, I guess that wasn’t good enough for Dave, so he designed the Pro Flows to make it even better. I’ve said it a million times since installing them, but the Pro Flows have changed my life!! They are simply mandatory on any plane I fly. Perfect idle and glass smooth transition throughout the entire power ban. “Father” Don Brown
Thanks from Ty Keith…………..Dave thanks for all the help. It's a real pleasure to find someone like you that builds a superior product and stands behind it 100%. Been great talking to you. Thanks for all the help. BTW- love the Pro Flows.
Thanks from psk560……………."I just had to tell you how much fun I'm having with your cans. My DA 170 purrs like a kitten and the engine is pulling my QQ 120 inch out of a hover with authority (45 lb plane at the least)... Loving the combo and the ability to drop down in a harrier and not have my engine sag when I add throttle. Great stuff!" Craig
Comment From Pops……………….. "after running the DA-200……………DAVE AND PRO FLOW ...OUT OF THE PARK..... I can't top what Brian Said about these. Guys, out there in IMAC land if you get a chance at the sticks with these on- you will be saved. Truly one of the most innovative exhaust systems out there and a big plus for helping with the Demon sound. The performance was such an improvement that Brian even let Brad Petty fly his IMAC machine and for once Brad was speechless. Dave……….you da man. Guys, if it ain't Pro-Flow you are just blowing hot air!!"
From ericb…………….."I have them on both my 55's and love them. I will not run anything else in my planes after flying with the Pro Flow's."
From Air-Stormer……………… "I would like to say thanks a million to Dave for such a great product... Finally maidened my Krill this weekend and all I have to say us wow! I ran pro flows on a ZDZ 180 and turned a 30x13 evo L over 6600 rpms! Performance was insane! What an awesome product".... Jamie Thomas
Note From Travis…………."Well Dave- you got another satisfied happy customer! I got the first flights in today on my DA85/Pro Flow combo. I think "night and day" sums it up in the difference between thePro Flow canister and the KS95 that I was running. The throttle response is very linear and I completely took out the throttle curve that I had set up with the KS95. I also picked up about 200 RPM over the KS95. Up until now I had been pulling my hair out with this engine to the point of just wanting to get rid of the thing. My mind has been changed now though. It is like having a new toy all over again. Big time thanks Dave."
Comments from Terryscustom……….. "I love my new pro-flow even though I only got a couple of flights on it!!! Super smooth with no "peak" spot! I knew the plane was awesome, but it is super smooth with the Pro Flow!! I think I need to order one for my 89" Slick."
A Word From Colton…………."Ok I'm 100% sold on these cans!
After my video I was already way pleased with how the 170 preformed on the Pro Flow cans vs how it was running before. I had become very accustomed to running the engine just a little rich on the low end and didn't notice it. Long story short Dave gets in touch with me and tells me from that video he could tell that I was just a little rich on the low end and told me to lean it just a tiny bit. And BAM there it is!...even better than I imagined. I really didn't think cans could make this much of a difference but they do.
So I had also had a set for the 100cc coming as well and what do you know they did the same thing. Now granted my TMM 106 I'm running currently on my Edge has been running wonderfully on stock mufflers and I had no problems with it except for maybe one very small power surge at 1/3rd throttle. I put the Dave's 100cc Pro Flow cans on the TMM today and gave it a tune and I could audibly tell I gained a small amount of RPM and more importantly the throttle transition fells like glass. For every tiny movement of the stick you can hear the RPM change.
I have tried many, many canisters and tuned pipes over the years and I will not put another exhaust on an aircraft that wasn't made by Dave.
I hope everyone else has results like I have and I'm sure Dave will do everything to help you.
Thanks Dave!"
From Dave and James…………….."Hey Dave..... We've had four different exhaust systems on that Python. We started out with a Greeves pipe then switched to an RE-3 with a 14" header. That produced power, but was just too loud so we switched to an MTW 110 canister. But still didn't have the mid-range we wanted. Your canister obviously did the trick........ We didn't even change the needles yesterday; just put on the Pro-Flow, cut the header down to 10.5", and you can see the results. The video (on Dave's Video Page) tells the tale. This combination is a keeper!! Thanks Brother."
From Jamie Mason……………."just purchased a set of Pro-Flow rear dump for my extra 260 with a DA 120. Installed my new canisters and just test flew the plane today. I cannot believe how smooth my transition is from mid to high range. No bobbles. These canisters are smooth and really increased my flying ability tremendously. I can't thank PlaneBender enough for designing these canisters."
By Scott Z………….."I got up before the snow came and pulled the DA 170 outside (17 DEGREES) put the wings on an started it up with the ProFlow cans- they sound like a quiet muffler should.The motor had an electric motor feel from idle to full throttle. They were much better than the KS 95's and even smoother than the stock DA mufflers which are obnoxiously loud. Good work PlaneBender."
From Jamie Thomas…………"I would like to say thanks a million to Dave for such a great product... Finally maidened my Krill this weekend and all I have to say us wow! I ran Pro-Flows on a ZDZ 180 and turned a 30x13 EVO L over 6600 rpms! Performance was insane! What an awesome product."
From Luvthestang……………"Dave- Great Product. Well I got to start her up and fly yesterday... Wow what a sound. I would buy these cans over any others if everything else was equal just for the sound!!!! But... add in that my idle was so slow and so smooth I felt I could catch the prop out of the air. The transition was very smooth I will have to relearn my plane and throttle control as this is almost like an big 126" electric now………Thanks for the great product.
From Mbacosa……………"Ok guys I finally got to try out my Pro-Flows on my DA200 this Sunday and all I can say is WOW!! I was thoroughly impressed and excited. I have to say that the motor actually runs smoother now and seems to have a little better throttle response. I have outstanding power. I tached the motor hot and it was turning 6350 on the ground with a 30X13 EVO L. In the air it is so quiet I am going to have to get used to that. I can't hear it at all when another plane is in the air. I didn't notice any power loss when flying. It still pulls just as well as it did with the stock mufflers. I am very pleased to say the least. Thanks Dave for a great product, Mike"
From RC4flying…………………I am a happy flyer now. These Pro Flow Canisters have made my day.
I too had problems with the way my engine ran on MTW 110, RE3's and KS 95's. I swapped out my recent MTW's and chopped the headers. Now I am smiling again. I was able to get nice even throttle changes and transitions without much difficulties. I am still getting the needles dialed in, but flying 3D without the worry of the hesitations make me feel better. I was getting no throttle response during TR'n and after long low throttle runs. That is a problem when hanging on the prop and the plane starts tail sliding because the throttle would not respond. Issue free from what I am experiencing now.
All I can say is "Thank You Dave Sullivan" for taking the time to figure out the problems this engine was having on cans and pipes."
From Dan Kippen………….."I haven't used the Greves but used the R-3s, then I went to the Pro-Flows. As soon as I did this the DA-170 became a totally different and reliable motor it was designed to be. I don't fly 3-D anymore but hear they are great for that. I do fly IMAC and have found the throttle transition is better than any tuned pipe out there."
From James……………."Finally got around to flying our new Extreme Flight 110" Yak today running a DA120 /11 inch flex headers/ and front dump Pro-Flow canisters. All I can say is ...WOW! The combo of the DA120 and Pro-Flow canisters was the closest I've ever got to perfect out of the box! We left the needles stock and with a "break in" prop (Vess 28B)- the setup flew great. We leaned the low end a little the first two flights...but damn this setup works good. Thanks for the great product Dave"
From 1bigben………. "I recommended the Pro Flows to a friend and installed and ran them this weekend. Talk about an impressive product to handle and the reduced sound output was stunning. Now that darn prop makes all the racket. I think he can enter an electric contest and be a true spoiler!"
Comment from TR2000…………. "Just fired up the DA 170 with pro flow's and the DA 120 with Pro-Flow's They both sound great! They both seem very smooth with great transition. Already I can tell both will run very well compared to the KS unit and Greeve pipes on the DA 120."
From Patrick H………….."Pro-flow baby!
I live half a world away and Dave was real easy to deal with. Could not get better service."
From 2 Dogs……………"Hey Guys………I ordered a set today for my new Extra and Dave spent 30+ minutes on the phone with me giving me all kinds of tips and advice. You don't see that kind of service very often. Thanks Dave"
From Hollywoodjax……………"I got a few more flights in Saturday with my pro-flows! Man I love the sound that they make. I like the way my throttle feels the most. Happy customer here."
From Sid…………The Pro Flow (baby) muffler is a drop-in fit. I will mount it in the modified Mojo this winter for flight in spring. My opinion: nice idle, easy transition - up and down, can't wait to see how it fly’s!!!! Great, this muffler is NICE!!! Thanks for a great product, Dave!!!
