Maybe this question been ask before.. how well the GRP .tuned .21 work with a JP-3 pipe?

Anyone knows how to get in touch with GRP in regards to warranty?
I purchased a new GRP promo kit and the engine's piston went bad on the only 2nd tank of fuel.

If you got it a hobbyshop you should go back to them and see if they will contact Horizon Hobby for you about it, if you got it online then you will probably have to contact Horizon yourself.

I finally got a few nice days with out rain and had a great day running my rc's. I made a couple of changes to the GRP.21. I replaced 2 of the standard springs for hard springs on the fioroni clutch and changed from the JP4 pipe to a dynamite 053. Man I cannot believe the difference. My GRP .21 now has great bottom end. I believe the problem I was having before was in the clutch. I built a track on the back of my propert a couple of years ago with a d4 cat and I use it for practice and tuning. At full race speed today I timed 4 full tanks lowest runtime was 11:10 and longest 11:30. Run time was in a Jammin x1x buggy. Engine is now very smooth with enough bottom to pitch it sideways on demand.

I have been looking at the GRP .21 engine and pipe combination. From what I have read it looks like a great engine. The person I met from Birmingham Alabama(I'm new to the area) told me he loves them and that recently many have switched to the GRP. I think maybe he drives for GRP.

At any rate I think I may shop with www.carolinasrc.com because it looks as if they have great specials and prices. I signed up for a email news special fromt hem and with the special code I can get the engine for $339 shipped. I'll be getting either a Losi or Mugen Buggy and all the stuff to go with it so If I can find better prices that would be great. Does this sound good to you guys?

What plug should I use?

I am guesing this is the only engine combo they make?

sounds good buddy you in birmingham ...im guessing you spoke with alan burton? run a odonells 98t or a o.s. p-3 ...but do yourself a favor and read this whole thread before you decide ...some say after running an o.s. that you will have problems switching back to others ...i have seen also where some plugs will cause others not to seal right and cause problems ....im here near alabaster about 20 minutes to birmingham .. ive got the motor you are looking at and finishing up the break in ...im running odonells 98t's and have had the same one in there for the duration of the break in ...holler at me on personal message if you need any more help ...would be glad to help you out ....later

What about the price? How does that sound to you? I'm just gonna run the grp plugs even though they are a little more.

Yes it was Alan Burton I'm pretty sure. How does his engines look/sound during local meets?

Do y ou have a email for him?

Thanks for your help!

yeh price sounds right with shipping ...is that the combo or just the motor?
well he wins alot around here ...he is one of the true pro sponsered drivers around ...motor with the grp pipe doent have the sound you will be acustom to ....but will run all day at 185-190 on a full race tune and will get easily 10 and a half minutes if not 11 to 11 and a half ...you will be pleased ...just get some tips from burton or myself before you start to break it in and run it .....they tune a little different that what you probably use to
