yearnin to Fly -> CRRC-pro GP26R 26cc gas engine information thread. (3/22/2010 8:03 PM)

I am starting this thread so anyone who has questions directly related to the CRRC-pro GP26R 26cc gas engine can post them here. Also if you have any experience you have had with them and want to post that please do.

I am doing this in hopes of helping others to find answers to the questions they may have.

Thanks to everyone for keeping this thread clean and clear of any bashing.

God bless !!!

I have one of these engines I am running on a test stand and have even bolted it to a profile katana to check it for fit.

So far the engine has plenty of power to fly the 26cc size katana and will hover it with ease. I hope to post pics soon.

I do sell these engines, so let me know if you have any questions.

Any news about the engine?

Any news about the engine?

Yes so far the engine is still breaking in. It builds more power the more it runs and breaks in.

I have been flying it on a Katana prifile plane with a 63 inch wing span and it will hover the plane at about 3/4 throttle.

I am well pleased with this little motor. I have even started stocking them here in my shop to sell.

I've recently purchased one of the rear carb CRRC 26 but have not started the break-in process. I own two of the side carb 26's and really like them with one in a 90 Funtana and the other in a Goldberg wildstick and they both perform great but not truly 3D capable. I'm anxious to see how the rear carb stacks up against the side carb units. I'll break the engine in on the wildstick. Just out of curiosity, where could I find a profile katana for this engine?

A comparison of specs for the two 26cc engines. Not only does it appear that the rear induction develops more power, but it seems that they also improved the ignition.

SPECIFICATIONS: CRRC GP26R engine rear induction

Type: 2 cycle rear induction reed valves type gasoline engine for airplane.
Displacement(cc): 26cc
Bore x Stroke(mm): 34mm*28.6mm
Dry Weight: 1.08kg/2.376lbs. (With engine mount, muffler and CDI)
Carburetor: Diaphragm butterfly valve type

Has anyone confirmed the specs for the rear induction model?

Breaking in one for a friend. So far 20oz Stihl HP Ultra at 32:1.  APC 18X6W, Pitts mffler. Low rpm - 2010, high - 7950. Will be put into QS 72" Yak. Closed the hole in the choke for better first prime. Used sticky back sand paper to make friction disc for prop. So far good running engine. Wish shaft was drilled for center bolt.



fillopygeesi -> RE: CRRC-pro GP26R 26cc gas engine information thread. (6/8/2010 9:45 PM)

Hello, I have this same engine and I cant get it to run good, it wont idle, its hard to start, and revs very slowly. I dont really know much about gas Ive only ever done parkzone electrics so has to be something im doing. It also vibrates quite badly is this normal

Give me a call and I will try to help you. I am usually in the shop from 9m to 6pm central standard time monday through friday.
I think I may know what you have wrong, 618-566-4102, My name is David.

KBoatCrew -> RE: CRRC-pro GP26R 26cc gas engine information thread. (6/11/2010 6:59 PM)

How do go about setting the timing on the CRRC? Isn't the Hall Sensor fixed and not adjustable?
Please let me know as we had a similar problem.

Thanks!

Do you also handle the 50cc twin?   Thanks  Capt,n

Does anyone, know of anyone who makes mufflers for the CRRC pro GP26R engine that will make them ALOT quieter?

Thanks for any help!!!



jedijody -> RE: CRRC-pro GP26R 26cc gas engine information thread. (8/2/2010 8:12 PM)

CRRC does.

Hi Jody, do you guys sell these? I would rather buy from you. Thanks~!!!!!!!!!!!!!!!

mpascual -> RE: CRRC-pro GP26R 26cc gas engine information thread. (8/2/2010 8:40 PM)

I agree with Jody:

CRRCpro engines (all 26cc versions) are much more quieter with this canister muffler.
(Also the DLE30, but enlarging the header intake the same as the exhaust port of the DLE30)

Regards

I purchased a Profile Katana with one of these CRRC 26 engines. I got it 2nd hand. The original owner got it from a person but people are asking if anyone in the USA is selling this combo kit. I saw it listed in the UK but not USA. The original owner tuned the engine and built the kit, but so far, the engine is flying just fine as far as reliability. The throttle linkage arm is a bit funky. The throttle servo needs to have a short arm and I even had to turn down the ATV alot which yields a pretty short throttle linkage movement. Anyone have a clue on the amount of mAh pulled per flight on the ignition battery?

I sell these planes out of my shop. I have flown mine alot and am currently using it to learn 3d on. I am getting ready to order more of these planes if you want one, just send me an email.

I use the CRRC-Pro GP26R rear carb on mine, ( it is one of the engines I sell here in the shop for the folks I do nitro to gas airplane conversions for) and it has MORE than enough power to do anything I want.



fillopygeesi -> RE: CRRC-pro GP26R 26cc gas engine information thread. (3/5/2011 7:03 PM)

Hey its been a while but Ive still had no luck with my crrcpro 26. At one time you told me I could send it to you. Was wondering if you would still be willing to help and how much.



Neo gold -> RE: CRRC-pro GP26R 26cc gas engine information thread. (3/11/2011 12:43 AM)

Anyone else running one of these?....how do they compare to the V2 version?...i'm soo tempted to get one ...they are very cheap at the moment...had my old v2 for ages now...only problem was a worn bearing & so easy to replace with superior SKF bearings...now runs better than ever...GP26R as loud?...as smooth ?.



fillopygeesi -> RE: CRRC-pro GP26R 26cc gas engine information thread. (3/11/2011 2:44 AM)

I have the V2 version and have had no luck with mine. It was beleived that a certain handfull of them had the timing incorrect from the factory. Evidently I bought one of the ones that was because mine ran really crappy, vibrated somthing awfull, and would deliver full rpms. I was told it could be easily fixed with a timing kit so I tried that. The engine behave better but still not much power and wouldnt idle. Id like to find somone with more eperience to see about getting it to run right if possible but the guy I talked to that had delt with the same problem on multiple CRRC engine to said he closed his shop.
